Abstract

PROBLEM TO BE SOLVED: To provide a device that automatically turns off an ampere breaker during a power failure, which can be installed without a prescribed qualification.SOLUTION: In the device that automatically turns off an ampere breaker, an electric signal is generated in a detection piece of a non-contact sensor arranged adjacently to an input line or an output line for an ampere breaker, by a capacitance due to the voltages acting on the input line or the output line. Consequently, since the electric signal due to the capacitance is not generated in the detection piece during a power failure, the device detects that the electric signal is not generated, activates an actuator and switches a switch lever of the ampere breaker locked to the actuator through a connection tool, from a connection state to a disconnection state; and further confirms safety of an electric apparatus linked to an individual breaker and then switches the switch lever of the ampere breaker to the connection state so that a secondary disaster can be prevented.

Description

The present invention provides a changeover switch that is interposed in an electric circuit between an input line (primary side) and an output line (secondary side) and switches the electric circuit from a connected state to a disconnected state when the electric circuit becomes abnormal. The present invention relates to a switch automatic disconnecting device at the time of a power failure that automatically switches the selector switch to a disconnected state sometimes.
In particular, the present invention relates to a changeover switch automatic disconnection device at the time of a power failure that automatically disconnects an ampere breaker, a leakage breaker, etc. installed in a distribution board at the time of a power failure.
More specifically, the present invention relates to an automatic switch-off device that can be retrofitted to a distribution board during a power failure.
More particularly, the present invention relates to an automatic changeover switch disconnecting device at the time of a power failure that can be easily attached to a distribution board.
Further, the present invention relates to an automatic changeover switch disconnecting device at the time of a power failure, which can be easily attached to a distribution board and is inexpensive.
Furthermore, the present invention relates to a power recovery notification device that can notify the power recovery after a power failure.
In addition, a changeover switch that is connected to the input line (primary side) and the output line (secondary side) and switches the circuit from the connected state to the disconnected state causes an earthquake of a specified seismic intensity or more in addition to a power failure. In such a case, the present invention relates to a changeover switch automatic disconnection device that automatically sets the changeover switch in a disconnected state at the time of a power failure or an earthquake.
The “switching switch” used in the present specification includes an ampere breaker, an earth leakage breaker, a safety breaker, or a switch having a function similar to these. An ampere breaker is a device that has the function of automatically shutting off the supply of electric power that is contracted between an electric power company and a customer, that is, when a current exceeding the “contracted amperage value” flows. It includes a limiter, service breaker, contract breaker, and similar devices, as is said in other electric power companies. The earth leakage breaker is a device having a function of detecting a current flowing at the time of earth leakage and automatically cutting off a circuit. A similar device is a device having a function of opening an electric circuit when an abnormal overcurrent flows through the electric circuit from the primary side to the secondary side.

  As a first prior art, an earthquake detection means for detecting the occurrence of an earthquake having a predetermined seismic intensity, a power failure detection means for detecting a power failure of a commercial power supply, and the power failure detection after the earthquake detection means detects the occurrence of an earthquake A control signal output means for outputting a control signal when the means detects a power failure of the commercial power supply; and a forcible opening means for forcibly opening the breaker when the control signal of the control signal output means is input. A circuit breaker with a seismic function characterized by the above is known (Patent Document 1).

  As a second prior art, a buzzer, a lamp, a reset switch, and a relay switch are provided. Between the lead-in wire attachment point of the 100V or 200V lead-in (input) line and the circuit breaker for wiring The relay switch is closed when the lead-in wire is connected to an arbitrary position and the lead-in wire is connected to the indoor wiring, and the relay switch opens when no power is applied to the lead-in wire due to a power failure. The lead-in wire and the indoor wiring are cut off, and when the voltage is applied to the lead-in wire again, current flows through the buzzer and lamp to emit sound and light, while the relay switch remains open without being activated. When the shut-off state is maintained and the reset switch is manually turned on, the relay switch is closed and then becomes conductive, and power supply to the indoor wiring is maintained. It is known disaster breaker characterized (Patent Document 2).

  As a third prior art, there are a plurality of main power breakers inserted in a main power circuit supplied with power from a commercial power source, and a plurality of power supplies branching from the main power circuit on the secondary side of the main power circuit breaker A branch breaker inserted in each branch circuit, a power failure detection unit for detecting a power failure in which the commercial power supply stops power supply, and a power failure detection unit that detects a power failure, at least partly from the main circuit There is known a distribution board comprising an opening / closing part that cuts off power supply to the branch circuit (Patent Document 3).

Japanese Patent No. 3351966 (FIG. 1 to FIG. 18, paragraph number 0012) JP-A-9-093805 (FIGS. 1 and 2, paragraph number 0016) JP2012-249391 (FIGS. 1-7, paragraph numbers 0026-0046)

  In the first prior art, in the event of a power failure after an earthquake of a predetermined value or more, in order to prevent the occurrence of a secondary disaster such as a fire due to the ampere breaker being connected, a predetermined by the earthquake detection means When a power failure is detected by the power failure detection means after the detection of the above earthquake, the ampere breaker in the distribution board is automatically disconnected. This has the advantage that the occurrence of secondary disasters due to re-energization after an earthquake can be suppressed. However, in the first prior art, the ampere breaker is not automatically disconnected even if there is a power failure unless the earthquake detection means arranged in the distribution board detects an earthquake exceeding a predetermined value. A secondary disaster may occur. For example, since the distribution board and the place where the electrical appliances are located are different from the place where the distribution panel is located, if the earthquake detection means in the distribution board does not detect an earthquake of a predetermined level or more, if a power failure occurs after the occurrence of the earthquake, Ampere breakers are not automatically disconnected. In this case, for example, when a combustible material falls on the hair dryer, there is a problem that the hair dryer operates due to re-energization after a power failure, and a secondary disaster such as a fire is likely to occur. Can not.

  In the second conventional device, regardless of the presence or absence of an earthquake, when a power failure occurs and no current flows through the input line of the ampere breaker, the ampere breaker is automatically disconnected because the relay switch does not act. After that, when the power is restored from a power failure, the ampere breaker is connected by checking the lamp or buzzer that notifies the restoration and pressing the reset switch. Technology. However, relay switches and reset switches must be incorporated in the distribution board. In Japan, the wiring change work in the distribution board can be performed only by a person with a predetermined qualification, so that the cost is high and there is a problem in spreading it to the existing distribution board.

  Even in the third prior art, when a power failure is detected by the power failure detection unit, the switch provided between the main power breaker and the branch breaker is opened, so that there is an advantage that a secondary disaster after the power failure can be prevented. However, there is a problem similar to the second prior art and a problem that the cost is increased because a switch is newly arranged.

First, the non-contact sensor 162 will be described mainly with reference to FIGS.
The non-contact sensor 162 detects that a voltage is applied to the input line 148, in other words, no voltage is applied to the input line 148 in a non-contact (non-connected) state, and outputs a power failure signal PFS. In the first embodiment, the capacitance sensor 170 is used. In other words, the non-contact sensor 162 outputs the energization signal RPS when it does not output the power failure signal PFS. The non-contact sensor 162 is not limited to the first embodiment, and can be changed to one having the same function, for example, a sensor using electromagnetic induction.
The capacitance sensor 170 according to the first embodiment includes a detection piece 172, an operational amplifier 174, a rectifier circuit 176, a threshold circuit 178, and a comparison circuit 180.

First, the detection piece 172 will be described.
The detection piece 172 has a function of outputting an electrical signal under the influence of the voltage applied to the input line 148 in a non-contact (non-connected) state with respect to the input line 148. In the first embodiment, the capacitance sensor 170 is formed of a rectangular plate made of a conductor, and is disposed close to the input line 148. Specifically, in the first embodiment, a first detection piece 172A and a second detection piece 172B are provided. This is because the non-contact sensor 162 is configured by a pair of detection pieces 172A and 172B, thereby simplifying the circuit configuration and manufacturing the device at low cost. In the first embodiment, the first detection piece 172A and the second detection piece 172B are close to the input lines 148A and 148B to which the voltage is applied among the three lines from the front side of the lid-side distribution board cover 126L.

Specifically, the first detection piece 172A and the second detection piece 172B are disposed to face the input lines 148A and 148B in the vicinity of the input line terminal portion 151A. As a method for attaching the first detection piece 172A and the second detection piece 172B, the first detection piece 172A and the second detection piece 172B can be attached to the surface of the lid-side distribution board cover 126L with a double-sided tape or an adhesive. In the first embodiment, it is attached to the back surface of a bracket 250 described later. With this configuration, when an AC voltage is applied to the input lines 148A and 148B, voltage application and non-application are alternately repeated on the input lines 148A and 148B. The alternating signal ACS shown in FIG. 8A is output from 172A and the second detection piece 172B in response to the application and non-application of the voltage.

It is out.
First, the operational amplifier 174 will be described.
The operational amplifier 174 is a known operational amplifier and has a function of amplifying an input signal and outputting the amplified signal. In other words, the detection signal DS from the first detection piece 172A and the second detection piece 172B, in other words, the alternating signal ACS is amplified with a predetermined amplification factor, and the amplified signal AMS is amplified as shown in FIG. Has a function to output.

Next, the rectifier circuit 176 will be described.
The rectifier circuit 176 has a function of rectifying an AC input signal. That is, the amplified signal AMS from the operational amplifier 174 has a function of rectifying and outputting as a DC signal DCS as shown in FIG. 8C, and a known rectifier circuit is used.

Next, the comparison circuit 180 will be described.
The comparison circuit 180 compares the input signal with the threshold CMS output from the threshold circuit 178, and has a function of outputting an abnormal signal ES when the input signal, that is, the DC signal DCS is lower than the threshold CMS. The comparison circuit is used. Specifically, when the output voltage of the rectifier circuit 176 falls below the voltage from the threshold circuit 178, the power failure signal PFS shown in FIG.

Next, the threshold circuit 178 will be described.
The threshold circuit 178 has a function of outputting a constant voltage threshold CMS to the comparison circuit 180. Specifically, a known threshold circuit is used which has a function of outputting the threshold CMS shown in FIG.

Next, the actuator 164 will be described.
The actuator 164 has a function of switching the switch lever 144 of the ampere breaker 128 from the connected state CS to the disconnected state AS. It has a function to make it a cut state AS. Therefore, if this function is provided, the actuator 164 can employ various actuators.
The actuator 164 in the first embodiment includes an electric motor 184, a speed reducer 186, a clutch means 188, and a take-up reel 192.

First, the electric motor 184 will be described.
The electric motor 184 functions as a drive source for the actuator 164. In the first embodiment, a small DC motor 194 used for a model or the like is used. This is because it is small and can be easily obtained at low cost. The DC motor 194 has an output shaft 196.

Next, the speed reducer 186 will be described.
The speed reducer 186 has a function of reducing the rotation of the output shaft 196 of the DC motor 194 at a predetermined speed reduction ratio and outputting it from the speed reduction output shaft 198 (FIG. 7). The reduction gear is used. These gears may be made of resin, metal or the like.
The electric motor 184 and the speed reducer 186 are installed in a rectangular drive unit box 190.

Next, the clutch means 188 will be described mainly with reference to FIG.
The clutch means 188 has a function of selectively interrupting the driving force between the deceleration output shaft 198 and the take-up reel 192, and is constituted by the friction clutch 200 in the first embodiment. However, other clutch structures can be used if they have similar functions. The friction clutch 200 according to the first embodiment includes a taper body 202 attached so as to rotate integrally with the deceleration output shaft 198, a slide taper body 204 integrated with the take-up reel 192, and a taper body 202. It includes a spring 206 that pushes to the right.
The tapered body 202 includes an outward tapered portion 212 and a cylindrical portion 214 that are attached to the small diameter portion 208 at the tip of the deceleration output shaft 198 so as to rotate integrally with the key 210, and at least only the outward tapered portion 212. That is good. The taper body 202 is prevented from falling off even when the pressing force of the spring 206 is applied by the first retainer 216 locked to the tip of the deceleration output shaft 198.
The slide taper body 204 has a cylindrical shape, and is attached so as to be slidable and relatively rotatable along the deceleration output shaft 198 by inserting an intermediate portion of the deceleration output shaft 198 into the center hole 218. Further, an inward taper portion 220 that is inclined at the same angle as the outward taper portion 212 is formed around the center hole 218 on the taper body 202 side. A take-up reel 192 described later is fixed to the outer periphery of the slide taper body 204. The spring 206 is disposed between the disk-shaped first spring receiver 226 and the second spring receiver 228 in which the deceleration output shaft 198 passes through the central through holes 222 and 224, respectively. The first spring receiver 226 is configured not to move to the base side of the deceleration output shaft 198 by the second retainer 246, and is configured to rotate integrally with the deceleration output shaft 198 by the key 231. However, the key 231 is not essential. The second spring receiver 228 is slidable in the axial direction with respect to the deceleration output shaft 198. Accordingly, the second spring receiver 228 is pushed toward the distal end side of the deceleration output shaft 198 by the elastic force of the spring 206, and the slide taper body 204 is pushed toward the taper body 202 side in accordance therewith. The tapered portion 220 is pressed against the outward tapered portion 212 with a predetermined force, and the driving force is transmitted to the slide tapered body 204 by the frictional force between the inwardly tapered portion 220 and the outward tapered portion 212. Thus, when the deceleration output shaft 198 is rotated, the taper body 202, the take-up reel 192, the first spring receiver 226, the second spring receiver 228, and the spring 206 rotate together and are connected to the take-up reel 192. The connected connector 168 can be taken up on the take-up reel 192. On the other hand, when the second spring receiver 228 is moved toward the first spring receiver 226, the slide taper body 204 does not receive a force toward the taper body 202. Thus, the slide taper body 204 can be manually rotated. As a result, the take-up reel 192 can be manually rotated, and the cord body 244 can be pulled out of the take-up reel 192 by pulling the cord body 244 with a locking member 242 described later. This is convenient when locking the locking tool 242 to the switch lever 144.
The clutch means 188 can be a meshing clutch when the friction clutch 200 has insufficient transmission torque due to insufficient frictional contact area due to installation space. For example, it is possible to improve the transmission torque by forming corrugated irregularities on the outward tapered portion 212 and engaging and forming irregularities opposed to the inward tapered portion 220.

Next, the take-up reel 192 will be described with reference to FIG.
The take-up reel 192 has a function of winding one end of a connection tool 168 whose one end is locked to the switch lever 144 of the ampere breaker 128 and winds the connection tool 168. A take-up reel body 230 and a slide taper body 204 are included.
The take-up reel body 230 is formed in a reel shape by flanges 232L and 232R in which the left and right ends of the cylindrical body 232 are enlarged in a bowl shape. The take-up reel body 230 is fitted and integrated with the outer periphery of the slide taper body 204. However, the take-up reel body 230 and the slide taper body 204 can be integrally formed of resin or metal.

Next, the control device 166 will be described mainly with reference to FIGS.
The control device 166 has a function of operating the actuator 164 when the power failure signal PFS is output from the non-contact sensor 162, and includes a timer circuit 234 and a switching circuit 236 in the first embodiment.

First, the timer circuit 234 will be described.
When the timer circuit 234 receives the power failure signal PFS, the timer circuit 234 outputs an operation signal PS for closing the switching circuit 236 for a predetermined time T. The predetermined time T in this case is a time sufficient to switch the switch lever 144 from the connected state CS to the disconnected state AS via the connector 168 by the operation of the actuator 164. Therefore, it can be changed to another device having the same function. In the first embodiment, as shown in FIG. 8E, when the power failure signal PFS is received, the operation signal PS is output for a predetermined time T.

Next, the switching circuit 236 will be described.
Based on the operation signal PS from the timer circuit 234, the switching circuit 236 has a function of closing the motor circuit 240 of the electric motor 184 and the battery 238 for the time T during which the operation signal PS is output. In the first embodiment, the switching circuit 236 is connected to the electric motor 184 and the battery 238 in series. Accordingly, when the switching circuit 236 is closed, the electric motor 184 starts rotating, and when the switching circuit 236 is opened, the rotation is stopped.

Next, the battery 238 will be described.
The battery 238 is an electrical energy source for enabling the actuator 164 to operate even during a power failure, and a known single-use or rechargeable battery can be used. Lead batteries, alkaline batteries, lithium batteries and other known batteries can be used. The battery 238 supplies electricity for operation not only to the electric motor 184 constituting the actuator 164 but also to the electric circuit constituting the non-contact sensor 162 and the control device 166. The sensor circuit 182, the control device 166, and the battery 238 are accommodated in a box-shaped battery box 248.
The battery 238 is a rechargeable secondary battery 344 as shown in FIG. 6 and is configured to automatically charge the electricity generated by the natural energy power generation device 346 with the charger 348. The problem can not be avoided. As the natural energy generator 346, a known natural energy generator such as a solar cell, a vibration generator, a wind generator, a small-scale hydroelectric generator, a wave power generator, an air thermal generator, or a combination thereof is used. I can do it. This is because the environmental load is not increased.
In addition, when automatic charging is not performed, in order to prevent the battery 238 from running out of battery, a voltage detection device (not shown) of the battery 238 is provided, and a battery running alarm is output when the voltage of the battery 238 falls below a predetermined value. It can be constituted as follows.

Next, the motor circuit 240 will be described.
The motor circuit 240 includes an electric motor 184, a switching circuit 236, and a battery 238. When the switching circuit 236 is closed, the electric motor 184 rotates, and when the switching circuit 236 is opened, the electric motor 184 stops.

Next, the connector 168 will be described mainly with reference to FIG.
The connection tool 168 has a function of connecting the actuator 164 and the switch lever 144, transmitting the operation of the actuator 164 to the switch lever 144, and switching the switch lever 144 from the connected state CS to the disconnected state AS. Includes a locking member 242 and a string 244. However, the connection tool 168 can be changed to another structure having the same function. By including the locking member 242 as in the first embodiment, it can be easily locked to the switch lever 144, and by including the string member 244, it can be easily attached to the switch lever 144 due to its flexibility. There are advantages.

First, the locking tool 242 will be described.
The locking tool 242 has a function of easily locking the string body 244 to the switch lever 144 by covering the tip of the switch lever 144. In the first embodiment, the stopper 242 is covered exactly on the tip of the switch lever 144. It is formed in a cylindrical shape with an open end so that it can be. Since the switch lever 144 has a rectangular cross section, the shape of the opening of the locking member 242 is similar to the cross section of the switch lever 144. With this configuration, the cord member 244 can be locked by covering the tip of the switch lever 144 with the locking tool 242, and thus there is an advantage that it can be easily attached. However, the locking tool 242 can be changed to another configuration having a similar function.

Next, the string body 244 will be described.
The string body 244 has a function of connecting the locking tool 242 and the actuator 164. In the first embodiment, the string body 244 is configured by a flexible string-shaped body formed of a fiber having high strength such as nylon fiber. One end is locked to the cylindrical body 232 of the take-up reel 192, a predetermined length is wound around the take-up reel 192, and the other end is fixed to the lock 242. The flexibility in the string body 244 means a lateral direction perpendicular to the longitudinal direction, and the longitudinal direction has no substantial flexibility. In other words, the string body 244 has substantially no stretchability in the longitudinal direction. Further, the string body 244 may be a rigid body having no flexibility depending on the combination with the type of the actuator 164.

Next, the bracket 250 will be described mainly with reference to FIG.
The bracket 250 has a function of easily installing the non-contact sensor 162 (including the detection piece 172), the actuator 164, the control device 166, or the battery 238. In the first embodiment, the bracket 250 includes the actuator 164 and the sensor circuit 182. The control panel 167 including the non-contact sensor 162 including the control device 166 and the battery box 248 containing the battery 238 are attached to the bracket 250, so that the ampere breaker automatic cutting device 102 is easily attached at the time of power failure. Further, since the bracket 250 is attached to the distribution board cover 126, the installation work can be performed very easily.
The bracket 250 has a rectangular shape in a front view and a rear view, and in a side view, the bracket 250 forms a substantially right angle with respect to the vertical plate 252 from the upper and lower ends of the vertical plate 252 to the rear side, and extends substantially horizontally. The upper horizontal plate 254 and the lower horizontal plate 256 are formed into a lateral channel type. The vertical plate 252 is disposed relative to the front surface 126F of the distribution board cover 126 (lid-side distribution board cover 126L) when mounted, has the same length as the front surface 126F, and the upper horizontal plate 254 has a distribution board. Arranged relative to the upper surface 126T of the panel cover 126, has the same length as the upper surface 126T, the lower lateral plate 256 is disposed relative to the lower surface 126U of the distribution board cover 126, and the lower surface 126U Have similar length.
The front end portion 254T of the upper horizontal plate 254 is formed in a downward arc shape so as to wrap around the back surface 126R side of the board-side distribution board cover 126B constituting the distribution board cover 126. As a result, the front end 254T can be hooked on the upper edge of the back surface 126R of the board-side distribution board cover 126B.
The front end portion 256T of the lower horizontal plate 256 is formed in an upward arc shape so as to wrap around the back surface 126R side of the board-side distribution board cover 126B constituting the distribution board cover 126. Thereby, the front end portion 256T can be hooked to the lower edge portion of the back surface 126R of the board-side distribution board cover 126B.
Further, an amper breaker through hole 258 is formed in a rectangular shape at the center of the vertical plate 252 so that the switch lever convex portion 146 of the amper breaker 128 can project.
The bracket 250 is formed of a flexible material, for example, resin, sheet metal or the like. When the bracket 250 is attached to the distribution board cover 126, the upper horizontal plate 254 and the lower horizontal plate 256 are used by utilizing the flexibility. Then, the vertical plate 252 is bent to expand up and down to move the tip portion 254T beyond the upper surface 126T and the tip portion 256T beyond the lower surface 126U to the rear surface 126R side of the board-side distribution board cover 126B. After the expansion is stopped, the bracket 250 returns to its original channel shape due to elastic force, and the vertical plate 252, the upper horizontal plate 254 and the lower horizontal plate 256 are placed on the front surface 126F, the upper surface 126T, and the lower surface 126U. It is attached so as to hold the distribution board cover 126 by being in close contact with each other and the front end portions 254T, 256T being hooked on the back surface 126R. Therefore, since no fixing screws or the like are used, the distribution board cover 126 can be easily attached.

In the first embodiment, the first detection piece 172A and the second detection piece 172B are attached to the back surface of the bracket 250 at the upper side of the ampere breaker through hole 258 so as to be opposed to the input lines 148A and 148B, respectively. Under the hole 258, the actuator 164, and thus the driving device box 190 and the battery box 248 are fixed, and the take-up reel 192 is disposed in the gap 260 between the driving device box 190 and the battery box 248. By arranging the take-up reel 192 between the gaps 260, the take-up reel 192 can be protected from accidental damage.
Normally, the connection tool 168 is suspended from the take-up reel 192 by gravity. With this configuration, when the bracket 250 is attached to the distribution board cover 126, the switch lever protrusion 146 protrudes from the amper breaker through hole 258, and in this state, the first detection piece 172A is connected to the input line 148A and the second detection piece. 172B is positioned relatively close to the input line 148B.
Thereafter, the locking tool 242 is put on the tip of the switch lever 144 and locked. Next, the second spring receiver 228 is moved away from the take-up reel 192 to eliminate the pressure contact force between the inward taper portion 220 and the outward taper portion 212, and the take-up reel 192 is turned by hand, and the extra string body 244 is taken up by the take-up reel 192. After the string body 244 is wound and wound, the second spring receiver 228 is released, and the inward taper portion 220 is pressed against the outward taper portion 212 with a predetermined force by the elastic force of the spring 206, and the clutch means Put 188 in the connected state.
Therefore, when the bracket 250 is attached to the distribution board cover 126, the non-contact sensor 162 (capacitance sensor 170), the actuator 164, the control board 167, and the battery 238 can be attached. There is an advantage that it can be mounted very easily by so-called one-touch.

  However, with respect to the first embodiment, the non-contact sensor 162, the actuator 164, the control panel 167, and the battery 238 are separately provided on the wall surface to which the distribution board cover 126 or the distribution board 100 is attached without providing the bracket 250. Can be attached. In addition, any one of the non-contact sensor 162, the actuator 164, the control panel 167, or the battery 238 is attached to the bracket 250, and the other is attached to the wall surface, or some of them are combined into the bracket 250. Mounting, etc. can also be mounted on the wall.

Next, the operation of the first embodiment will be described with reference to the output signal diagram shown in FIG.
At the time of energization in the normal state, the input lines 148A and 148B are periodically applied and stopped because they are connected to an AC power source. Corresponding to the voltage application and stop at the input lines 148A and 148B, the first detection piece 172A disposed in proximity to the input line 148A and the second detection piece 172B disposed in proximity to the input line 148B Depending on the capacity, an alternating signal ACS flows as shown in FIG.
As shown in FIG. 8B, the operational amplifier 174 outputs an amplified signal AMS obtained by amplifying the alternating signal ACS.
The rectifier circuit 176 rectifies the amplified signal AMS and outputs a DC signal DCS. The comparison circuit 180 compares the voltage of the DC signal DCS with the threshold value CMS output from the threshold value circuit 178. When the voltage is larger than the threshold value CMS, the power failure signal PFS is not output. Then, the power failure signal PFS is output (FIG. 8D).
The timer circuit 234 outputs the operation signal PS for a predetermined time T based on the reception of the power failure signal PFS (FIG. 8E).
While the operation signal PS is being output, the switching circuit 236 is closed and the electric motor 184 rotates. Since the reduction output shaft 198 of the speed reducer 186 is rotated by the rotation of the electric motor 184, the take-up reel 192 is rotated via the clutch means 188, and the string body 244 is taken up. By winding the string body 244, the switch lever 144 is pulled down in FIG. 3 via the locking member 242 and immediately after its posture becomes almost horizontal, a snap action mechanism built in the amper breaker 128 is used. The connection state CS is switched to the disconnection state AS. By this switching, the ampere breaker 128 is shut off (opened). As a result, even if power is restored, electricity does not flow to the electric device 121. When resuming the use of each electrical device 121, after confirming the safety of each electrical device 121 connected to the individual breaker 132, push the switch lever 144 of the ampere breaker 128 upward (counterclockwise in FIG. 3). Rotation) By returning to the connected state CS, each electric device 121 becomes operable.

Next, Embodiment 2 will be described with reference to FIG.
Explaining the configuration different from the first embodiment, in the second embodiment, the detection pieces 172 (first detection piece 172A, second detection piece 172B) of the capacitance sensor 170 are made to correspond to the output lines 150A and 150B in FIG. The driving device box 190 and the battery box 248 are integrated with each other. In the second embodiment, since the first detection piece 172A and the second detection piece 172B are disposed close to the output lines 150A and 150B of the ampere breaker 128, electricity flows to the output side of the ampere breaker 128. If not, in other words, if no voltage is applied, the actuator 164 is activated and the ampere breaker 128 is disconnected. Therefore, when a power failure occurs, the ampere breaker 128 is always set to the disconnected state AS. Further, since the driving device box 190 and the battery box 248 are integrated, there is an advantage that the mounting work to the bracket 250 is easy.
The operation of the second embodiment is the same as that of the first embodiment.

Next, Embodiment 3 will be described with reference to FIG.
A configuration different from that of the first embodiment will be described. In the third embodiment, the detection piece 172, and thus the first detection piece 172A and the second detection piece 172B, are attached to the ampere breaker 128 instead of the bracket 250.
Specifically, at a position facing the input lines 148A and 148B on the surface of the cover plate 264 covering the upper surface of the concave groove 262 in the input line terminal portion 151A where the terminals connecting the input lines 148A and 148C are arranged, The first detection piece 172A and the second detection piece 172B are attached. Of course, the first detection piece 172A and the second detection piece 172B can be attached to the cover plate of the output line terminal portion 151B. The input line terminal portion 151A is provided corresponding to the input lines 148A, 148B, and 148C, and terminals connected to the ends of the input lines 148A, 148B, and 148C are fixed screws 149A, 149B, and 149C ( FIG. 2) shows a structure fixed in a connected state.
In the configuration of the third embodiment, since the detection piece 172 is arranged at a position closer to the input line 148 or the output line 150, the voltage applied to the input line 148 or the output line 150 is more or less accurately applied. There is an advantage that application can be detected.

Next, Embodiment 4 will be described with reference to FIG.
Explaining the configuration different from the first embodiment, the detection piece 172 is arranged around the individual input line 148 (148A, 148B) or the output line 150 (150A, 150B). Specifically, the detection piece 172 is a ring-type detection piece 266, which is formed into a semicircular first semicircular body 266A and a second semicircular body 266B, one end of which is formed on the same support shaft 268. The tip 266AT and the tip 266BT on the opposite side are abutted against each other elastically like a clothespin. After the detection piece 266 is opened so that the tip 266AT and the tip 266BT are separated from each other, for example, the detection piece 266 is mounted so as to hold the input line 148A, and then the expansion is automatically returned and closed. Thereby, since the detection piece 266 is positioned around the input line 148A, an electric output by electrostatic induction can be obtained from the detection piece 266. When using this ring-shaped detection piece 266, the lid-side distribution board cover 126L must be removed and attached, but the wiring in the distribution board 100 is not changed, so no special qualification is required, and ordinary people wear it. This has the advantage that it can be installed inexpensively.

Next, a fifth embodiment will be described with reference to FIGS.
When a configuration different from that of the first embodiment is described, the structure of the connection tool 168 is greatly different. That is, the connecting portion 269 corresponding to the string body 244 is configured by the stretchable portion 270 that can be stretched within a predetermined range in the longitudinal direction and the rigid body 272 that has substantially no stretchability in the longitudinal direction. . The rigid body 272 means that it has substantially no stretchability in the longitudinal direction. Specifically, one end of the rigid body 272 is freely rotatable to a first rigid body 272A connected to the locking tool 242 and a support shaft 276 projecting sideways from a rotating disk 274 mounted in place of the take-up reel 192. And a second rigid body 272B supported by the second rigid body 272B. The stretchable part 270 includes a spring body 278 and an extension regulating string 280. One end of the spring body 278 and the extension regulating string 280 is fixed to the lower end portion of the first rigid body 272A, and the other end portion is fixed to the upper end of the second rigid body 272B. When the body 278 can be extended by the elasticity of the body 278 and is restricted by the extension restricting string 280, the support shaft 276 is integrated with the first rigid body 272A and the second rigid body 272B and the rotational disk 274 is rotated. The movement is transmitted to the switch lever 144.
The rotating disk 274 is fixed to one end surface of the slide taper body 204 in the first embodiment.
An action piece 282 extending in the lateral direction is formed at the end of the second rigid body 272B, and the rotary disk 274 is rotated, and the switch lever 144 is pulled down by the restriction by the extension restriction string 280 to enter the cut state AS. In this case, a micro switch 284 closed by the action piece 282 is arranged. The switching circuit 236 in the first embodiment is configured to be opened by closing the micro switch 284. Therefore, when the fifth embodiment is performed, as shown in FIG. 13, the timer circuit 234 in the first embodiment is not necessary, and the switching circuit 236 is generated by the power failure signal PFS from the capacitance sensor 170 (non-contact sensor 162). What is necessary is just to comprise so that it may be closed. This is because the opening of the motor circuit 240 can be performed by the microswitch 284. Specifically, the contact of the micro switch 284 is connected in series with the motor circuit 240. Further, in the fifth embodiment, without providing the first rigid body 272A and the second rigid body 272B, the upper ends of the spring body 278 and the extension regulating string 280 are directly attached to the locking member 242 and the lower end action piece 282 is attached to the support shaft 276. It may be attached directly to.

Next, the operation of the fifth embodiment will be described.
In a normal situation without any abnormality, as shown in FIG. 12 (A), in the connection state CS of the switch lever 144, the locking tool 242 is locked to the tip of the switch lever 144, and the support shaft 276 is top dead. As a result, the spring body 278 contracts and the extension restricting body 280 is in a relaxed state.
When the non-contact sensor 162 outputs the power failure signal PFS, the switching circuit 236 is closed, the electric motor 184 starts to rotate, and the rotating disk 274 is rotated clockwise at a slow speed via the clutch means 188 as in the first embodiment. To be rotated. By this rotation, the support shaft 276 moves away from the switch lever 144, so that the spring body 278 is pulled, eventually the extension regulating body 280 is tensioned, and the switch lever 144 is pulled downward via the locking member 242. When the switch lever 144 is lowered by a predetermined amount, the snap action mechanism built in the ampere breaker 128 is suddenly rotated from the connected state CS to the disconnected state AS, and the ampere breaker 128 is cut off (cut). Further rotation of the rotating disk 274 after the ampere breaker 128 is disconnected further pulls down the connector 168, so that the action piece 282 activates the microswitch 284 and opens the motor circuit 240, thus The rotation is stopped and the automatic cutting operation ends.
Therefore, according to the fifth embodiment, there is an advantage that the timer circuit 234 can be deleted.

Next, Embodiment 6 will be described with reference to FIG.
The sixth embodiment is an example in which the control device 166 is configured by a microcomputer 290.
Explaining the configuration different from the first embodiment, the output of the operational amplifier 174 is input to the microcomputer 290, and the output of the microcomputer 290 includes the base of the first transistor 292T as the first switching circuit 292, and the second switching circuit. 294 is output to the base of the second transistor 294T. The collector terminal of the first transistor 292T is connected to the electric motor 184, and the emitter terminal is grounded. The collector terminal of the second transistor 294T is connected to the LED 296 as a light emitter, and the emitter terminal is grounded. In the sixth embodiment, the combination of the second switching circuit 294 and the LED 296 is a power recovery notification device 297, and the power recovery determination unit 299 is configured by software as will be described later. The positive electrode of the battery 238 is connected in parallel to the electric motor 184 and the LED 296, and the negative electrode is grounded. Further, a recovery switch 298 for outputting a recovery signal RS is connected to the input of the microcomputer 290.

Next, the operation of the sixth embodiment will be described with reference to the flowchart of FIG.
First, in step S1, it is determined whether or not the alternating signal ACS is output from the operational amplifier 174. If it is not output, the process proceeds to step S2, and if it is output, step S1 is looped to enter a standby state. In other words, when the voltage is applied to the input line 148, the alternating signal ACS is necessarily output.
Next, in step S2, a power failure signal PFS is output and the process proceeds to step S3.
Next, in step S3, an actuator operation signal AOS is output, and the process proceeds to step S4.
In step S4, timing of the predetermined time T is started, and after measuring the predetermined time T, the process proceeds to step S5.
In step S5, the output of the actuator operation signal AOS is stopped, and the process proceeds to step S6. Therefore, the electric motor 184 rotates for a predetermined time T. In other words, the predetermined time T is set to a time sufficient to turn the switch lever 144 from the connected state CS to the disconnected state AS. As a result, while the actuator operation signal AOS is being output, a voltage is applied to the base of the first transistor 292T, so that the first transistor 292T is energized and the electric motor 184 rotates. As in the fifth embodiment, the connector 168 is pulled and the switch lever 144 is rotated from the connected state CS to the disconnected state AS.
When the power is restored, the operational signal 174 is output from the operational amplifier 174, and thus the power failure signal PFS disappears. Therefore, the output of the operational amplifier 174 becomes the power recovery signal RPS because the power failure signal PFS is stopped.
When the power recovery signal RPS is detected in step S6, the process proceeds to step S7.
In step S7, the LED lighting signal ALS is output, and the process proceeds to step S8.
Thus, while the LED lighting signal ALS is being output, a voltage is supplied to the base of the second transistor 294T, the second transistor 294T is energized, and the LED 296 emits light. In other words, the power recovery notification device 297 allows the administrator to perceive power recovery, and after confirming the safety of each electrical device 121, the recovery switch 298 is pressed to output the recovery signal RS.
If the recovery signal RS is detected in step S8, the process proceeds to step S9. If the recovery signal RS is not detected, step S8 is looped.
In step S9, the output of the LED lighting signal ALS is stopped and the process is terminated.
Therefore, the administrator can return the switch lever 144 of the ampere breaker 128 to the connected state CS after confirming the safety of the electric device 121, so that a secondary disaster can be prevented. In the sixth embodiment, step S6 is the power recovery determination unit 299, which is configured by software. However, the power recovery determination unit 299 having the same function can be configured by combining circuit elements.
In addition to illuminating LED 296 based on LED lighting signal ALS, warning sound by buzzer etc., sound of message, vibration by vibrator, mail transmission to pre-registered address, wireless communication, or different places by wire Notification can be made by a lamp, a display, or a speaker installed alone or by a combination thereof. By using such various notification means, it is possible to quickly grasp the power recovery, and as a result, there is an advantage that contributes to the rapid spread.
Further, without providing the recovery switch 298, the second non-contact sensor 310 is combined with the second non-contact sensor 310 in the eighth embodiment disclosed in FIGS. 17 to 20, the output of the second non-contact sensor 310 is “0”, and When the output of the first non-contact sensor 306 is “1”, the power recovery can be notified using the above-described notification means.

Next, Embodiment 7 will be described with reference to FIG.
The seventh embodiment is an example in which the output of the electric motor 184 can be kept low. That is, the use of a much smaller electric motor 184 achieves low cost and low power consumption.
Explaining the configuration different from the first embodiment, a lever-side connector 303 having a pulley shaft 302 connected to the lower end of the string body 244 to rotatably support the pulley 300, and a middle portion of the pulley 300 are wound around the pulley 300, One end is fixed to a fixing portion (not shown) of the bracket 250, and the other end is constituted by a winding side connection tool 304 including a second string body 305 wound around a winding reel 192.
In this configuration, as in the first embodiment, when the second string body 305 is taken up by the rotation of the take-up reel 192, the pulley 300 is pulled down, and as a result, the switch lever 144 is also pulled down from the connected state CS to the disconnected state AS. Can be switched to. In this case, the winding force (rotational torque) of the winding reel 192 that winds the winding-side connector 304 is half that of the first embodiment due to the principle of the pulley, and a further low-power motor is used. Therefore, cost reduction and power consumption can be reduced.

Next, Example 8 will be described with reference to FIGS.
The same functional parts as those in the first embodiment are denoted by the same reference numerals, and different configurations will be described.
In the eighth embodiment, the detection piece 308 of the first non-contact sensor 306 is arranged close to the input line 148 of the ampere breaker 128, and the detection piece 312 of another second non-contact sensor 310 is arranged close to the output line 150. It is. That is, the first detection piece 308A and the second detection piece 308B of the first non-contact sensor 306 are opposed to the input lines 148A and 148B in the same manner as the first detection piece 172A and the second detection piece 172B of the first embodiment. The third detection piece 312A and the fourth detection piece 312B of the second non-contact sensor 310 are attached to the back surface of the bracket 250 opposite to the output lines 150A and 150B as in the second embodiment. ing.
In the first non-contact sensor 306, the first detection piece 308A and the second detection piece 308B are connected to the first operational amplifier 314 as in the first embodiment, and the output of the first operational amplifier 314 is output to the first rectifier circuit 315. The output of the first rectifier circuit 315 is output to the first comparator circuit 316, the output of the first threshold circuit 318 is connected to the other input terminal of the first comparator circuit 316, and the output of the first comparator circuit 316 is The data is output to the computer 290. In other words, the first non-contact sensor 306 mainly has a function of detecting a power failure phenomenon and a recovery phenomenon from the power failure. When the output of the first rectifier circuit 315 is lower in voltage than the output of the first threshold circuit 318, the first comparison circuit 316 outputs the first power failure signal PFS1 of “0” (zero). When the voltage is higher than the output, the first energization signal RPS1 of “1” (one) is output.
In the second non-contact sensor 310, the third detection piece 312A and the fourth detection piece 312B are connected to the second operational amplifier 320 as in the second embodiment, and the output of the second operational amplifier 320 is output to the second rectifier circuit 321. The output of the second rectifier circuit 321 is output to the second comparison circuit 322, the output of the second threshold circuit 324 is connected to the other input terminal of the second comparison circuit 322, and the output of the second comparison circuit 322 is the microcomputer. Is output to 290. The second non-contact sensor 310 mainly has a function of detecting the connection state or disconnection state of the ampere breaker 128, and the second comparison circuit 322 has the second rectifier circuit 321 more than the output of the second threshold circuit 324. When the output is low voltage, the second power failure signal PFS2 of “0” (zero) is output, and when the output is higher than the output of the second threshold circuit 324, the second energization signal RPS2 of “1” (one) is output. .
The operation of the first non-contact sensor 306 and the second non-contact sensor 310 is the same as that of the non-contact sensor 162 in the first embodiment.
Accordingly, as shown in FIG. 19, when an AC voltage is applied to the input lines 148A and 148B, the first comparison circuit 316 outputs the first energization signal RPS1 having a high level. The output of the 1 comparison circuit 316 is “1”. The first comparison circuit 316 outputs the first power failure signal PFS1 at a low level (including zero) when the output of the first operational amplifier 314 is lower than the threshold value CMS. The output of the 1 comparison circuit 316 is “0”. In other words, the first comparison circuit 316 outputs the first energization signal RPS1 of “1” during energization, and outputs the first power outage signal PFS1 of “0” when a power failure occurs.
The output of the second comparison circuit 322 is the same. That is, the second comparison circuit 322 outputs the second energization signal RPS2 when the voltage is applied to the output line 150, the output is “1”, and when the power failure occurs, the second power failure signal PFS2 is output. The output is “0”. In other words, the second comparison circuit 322 outputs the second energization signal RPS2 of “1” during energization, and outputs the second power outage signal PFS2 of “0” when a power failure occurs.
Accordingly, the outputs of the first non-contact sensor 306 and the second non-contact sensor 310 are the outputs shown in FIG. 19 according to the power failure and energization state. The motor circuit 240 includes a battery 238, an electric motor 184, and a first switching circuit 292 as in the first embodiment. In the eighth embodiment, as in the sixth embodiment, the outputs of the first operational amplifier 314 and the second operational amplifier 320 are output to the microcomputer 290, and the processing in the first comparison circuit 316, the second comparison circuit 322, etc. is processed by software. These circuits can be deleted by substituting with the wearer.

Next, the operation of the eighth embodiment will be described with reference to the flowchart shown in FIG.
First, in step S11, it is determined whether or not the first power failure signal PFS1 of “0” is output from the first comparison circuit 316 of the first non-contact sensor 306 on the input side with respect to the ampere breaker 128. If it has not been output, step S11 is looped to enter a standby state. In other words, since the voltage is applied to the input line 148 in the normal state and the ampere breaker 128 is in the connection state AS, the output from the comparison circuit 316 of the first non-contact sensor 306 and the second non-contact sensor 310 The output of the comparison circuit 322 is also “1”, and the actuator 164 does not operate.
In step S12, the closing signal SS of the first switching circuit 292 is output, and the process proceeds to step S13. Due to the closing signal SS of the first switching circuit 292, the first switching circuit 292 is closed and the actuator 164 starts to operate. Therefore, since the electric motor 184 rotates, the take-up reel 192 rotates and the string 244 is taken up. To start.
In step S13, timing of the predetermined time T is started, and when the predetermined time T has elapsed, the process proceeds to step S14, and when the predetermined time has not elapsed, step S13 is looped.
In step S14, the open circuit signal OS of the first switching circuit 292 is output, and the process proceeds to step S15. In other words, when the power failure occurs and the first power failure signal PFS1 is output, the first switching circuit 292 closes the motor circuit 240 in the actuator 164 for a predetermined time T based on the closing signal SS. The electric motor 184 rotates during connection, and the actuator 164 pulls the connection tool 168 as described in the first or sixth embodiment due to the rotation, so that the switch lever 144 is connected when it is rotated by a predetermined angle. The state CS is switched to the disconnected state AS. Accordingly, the outputs of the first non-contact sensor 306 and the second non-contact sensor 310 in this situation are both “0”.
In step S15, it is determined whether or not the first power recovery signal RPS1 of “1” is output from the first non-contact sensor 306. If determined, the process proceeds to step S16, and if not determined, step S15 is looped. That is, when power is restored, the output of the first non-contact sensor 306 becomes “1”, but the output of the second non-contact sensor 310 remains “0”.
In step S16, the microcomputer 290 outputs the LED lighting signal LS and proceeds to step S17. The second switching circuit 294 is closed by the LED lighting signal LS, and the LDE 296 is lit. When the LED 296 is turned on, the administrator perceives power recovery and checks the safety of the electric device 121, and then presses the recovery switch 298. That is, after confirming that no secondary disaster will occur even if electricity is supplied to the electrical device 121, the recovery switch 298 is pressed.
In step S17, it is determined whether the recovery switch 298 has been pressed. If it is determined that the recovery switch 298 has been pressed, the process proceeds to step S18. If not, step S17 is looped.
In step S18, the extinction signal DLS for opening the second switching circuit 294 is output, and the process is terminated. The LED 296 stops emitting light by the turn-off signal DLS.
After confirming that the LED 296 is turned off, the operator returns the switch lever 144 to the connection state CS, and then returns the connection tool 168 to the original state again. As a result, the outputs of the first non-contact sensor 306 and the second non-contact sensor 310 are both “1”.
In the eighth embodiment, since the operation can be performed by detecting the application of voltage in the input line 148 and the output line 150, there is an advantage that an unexpected accident can be prevented.
In the eighth embodiment, the output of “0” or “1” from the first non-contact sensor 306 and the second non-contact sensor 310 is always monitored, and the first non-contact sensor 306 and the second non-contact sensor are monitored. When all the outputs of 310 become “0”, the first switching circuit 292 is closed and the actuator 164 is operated, the output of the first non-contact sensor 306 is “1”, and the output of the second non-contact sensor 310. Is “0”, the second switching circuit 294 can be closed to light the LED 296.

Next, Embodiment 9 will be described with reference to FIG.
In the ninth embodiment, the configuration different from the first and fifth embodiments will be described. In the actuator 164, the switch lever 144 is switched from the connected state CS to the disconnected state AS by the elastic body 325 instead of the electric motor 184, and the power consumption is reduced. The configuration is such that it can be suppressed.
Specifically, the bearing 327 at the lower end of the second rigid body 272B is rotatably attached to a fixed shaft 328 protruding from the bracket 250. The first rigid body 272A and the second rigid body 272B are connected by a spring 326 that is one of the elastic bodies 325. A retainer 330 is fixed to the lower end of the first rigid body 272A. The spring force of the spring 326 is set to a spring force that can move the switch lever 144 from the connected state CS to the disconnected state AS in the free state between the fixed shaft 328 and the switch lever 144. A holding device 331 is provided opposite to the retainer 330. The holding device 331 has a function of preventing the elastic force of the elastic body 325 from substantially acting on the switch lever 144. In other words, the switch lever 144 has a function of preventing the switch state 144 from being switched from the connected state CS to the disconnected state AS by the elastic force of the elastic body 325. Specifically, the holding device 331 prevents the elastic force of the elastic body 325 from acting on the switch lever 144 by holding the retainer 330 at the inoperative position NAP. In the ninth embodiment, the holding device 331 is a holding roller 338. The holding roller 338 is selectively switched so as to be positioned at a holding position HP positioned on the lower surface side of the retainer 330 and a non-holding position NHP deviated from below the retainer 330. When the retainer 330 is held at the non-operating position NAP by the holding roller 338, the elastic force of the spring 326 is supported by the holding roller 338 via the retainer 330, so that the first rigid body 272A is cut. The pulling force sufficient to shift to AS does not act, and the switch lever 144 maintains the connection state CS.
The holding roller 338 is moved to the non-holding position NHP by the holding release device 332.
The holding release device 332 has a function of moving the holding roller 338 located at the holding position HP to the non-holding position NHP, and includes a rotary solenoid 334 and an arm 336. That is, a holding roller 338 as a holding device 331 is attached to the tip of an arm 336 that extends laterally from the output shaft 340 of the rotary solenoid 334.
By using the holding roller 338, when moving from the holding position HP to the non-holding position NHP, the holding roller 338 is brought into rolling contact with the retainer 330 so that the frictional resistance becomes extremely small, so that the power consumption is small and a small rotary solenoid. An electromagnetic actuator such as 334 can be used and there is an advantage that it can be provided at low cost because a battery with a relatively low capacity can be used because of low power consumption.

Next, the operation of the ninth embodiment will be described.
In a normal time when no power failure occurs, the holding roller 338 is positioned at the holding position HP, and by holding the retainer 330 from below, the retainer 330 is locked at the non-operating position NAP. Since the elastic force of the spring 326 does not substantially act, the switch lever 144 continues the connection state CS.
When a power failure occurs and the rotary solenoid 334 is excited, the output shaft 340 is moved to the non-holding position NHP and the retainer 330 is unlocked, as shown by the chain line in FIG. It is pulled down by the spring force of the spring 326. As a result, the switch lever 144 is pulled down by the large force of the spring 326 and switched from the connected state CS to the disconnected state AS.
When power is restored, the retainer 330 is lifted, the arm 336 is manually rotated to move the holding roller 338 to the holding position HP below the retainer 330, and then the retainer 330 is locked by the holding roller 338. Prepare for the next blackout.

Next, Example 10 will be described with reference to FIGS.
The tenth embodiment is a change-over switch automatic disconnection device 352 at the time of a power failure or an earthquake, and in addition to the function of the changeover switch automatic disconnection device 102 at the time of a power failure described in the first to ninth embodiments, The function of automatically switching the switch lever of the change-over switch to the disconnected state is also provided when the signal is detected.
The tenth embodiment differs from the sixth embodiment, which has the same mechanical structure as the first embodiment, in that the structure of the actuator 164 is different and a seismic device 354 is added. In other words, the automatic switch switching device at the time of a power failure or earthquake in Example 10 automatically switches the switch lever by operating the switch lever when an earthquake of a predetermined seismic intensity or more occurs in addition to the effects in Example 6. Has the function of disconnecting the switch.

First, the overall structure of Example 10 will be described with reference to FIGS. 22 and 23. FIG.
The same parts as those in the sixth embodiment are denoted by the same reference numerals, description thereof is omitted, and different configurations will be described in detail. The tenth embodiment includes at least the non-contact sensor 162, the actuator 164, the control device 166, the drive device case 190, and the seismic sensing device 354.
These components include, for example, a control panel 167 and a drive device case 190 in which a control device 166 is mounted on the left end portion of the front surface of the second substrate 356, which is a substrate made of a rectangular flat plate, and are fixed in a stacked state. The actuator 164 is fixed to the right end, and the non-contact sensor 162 (detection pieces 172A and 172B) is fixed to the back surface of the second substrate 356. Then, the second substrate 356 and the like are arranged in a box-shaped case (not shown), and this case is fixed to a predetermined position of the distribution board cover 126, for example, by fixing means such as a double-sided tape. The seismic sensing device 354 is fixed to the distribution board cover 126 or the wall surface 460 of the building near the distribution board cover 126.

  The actuator 164 in the tenth embodiment will be described. In order to distinguish from the actuator in the first embodiment, it is hereinafter referred to as a second actuator 360. The second actuator 360 has the same function that can automatically switch the ampere breaker 128 from the connected state CS to the disconnected state AS by moving the switch lever 144 of the ampere breaker 128 that is a changeover switch. On the other hand, some of the components are different. Specifically, the second actuator 360 in the tenth embodiment includes an electric motor 184, a reduction gear 358 including a spur gear (hereinafter referred to as “spur gear reduction device 358”), a pinion gear 362, a rack 364, and a rack guide. Includes 366. That is, the rotation of the output shaft (not shown) of the electric motor 184 is reduced and transmitted to the reduction output shaft 198 of the spur gear reducer 358, the pinion gear 362 is rotated in a predetermined direction, and the rack 364 engaged with the pinion gear 362 is provided. The ampere breaker 128 serving as a changeover switch is cut by moving the rack 364 to bring the switch lever 144 into the cut state AS. The electric motor 184 is a direct current motor and can be reversed by changing the connection pole.

First, the spur gear reducer 358 will be described.
The spur gear reducer 358 has a function of reducing the rotation of the output shaft (not shown) of the electric motor 184 by a predetermined reduction ratio and outputting it to the reduction output shaft 198 by a spur gear train (not shown). It is configured. In the tenth embodiment, since the output shaft of the electric motor 184 and the deceleration output shaft 198 are at right angles, the drive shaft is transmitted to and from the output shaft of the electric motor 184 by a bevel gear (including a crown gear). However, this case is also included in the concept of the spur gear reducer 358. When the spur gear reducer 358 is used, by appropriately setting the reduction ratio, the rack 364 can be rotated even if it is manually moved. In other words, the rack 364 can be moved manually. There is. The electric motor 184 is fixed to the housing of the spur gear reducer 358.

Next, the pinion gear 362 will be described.
The pinion gear 362 is a gear that is fixed to the reduction output shaft 198 of the spur gear reducer 358 and is rotated, and meshes with the rack 364.

Next, the rack 364 will be described mainly with reference to FIG.
The rack 364 is driven by the pinion gear 362 and has a function of moving in a predetermined direction based on the rotation direction of the pinion gear 362. In the tenth embodiment, the rack 364 has a rectangular columnar straight bar 368 having a rectangular cross section. A large number of identically shaped teeth 372 are formed on one surface at a predetermined pitch. Therefore, the teeth 372 mesh with the teeth of the pinion gear 362.
Further, the rack 364 is guided by the rack guide 366 so as to move linearly in the axial direction thereof.

Next, the rack guide 366 will be described.
The rack guide 366 has a function of guiding the rack 364 so as to linearly move along a predetermined track. In the tenth embodiment, the rack guide 366 includes a guided portion 374 and a guide portion 376 formed in the rack 364. . However, it can be changed to another mechanism having a similar function.

First, the guided portion 374 will be described mainly with reference to FIGS.
As shown in FIG. 23 (E), the guided portion 374 is a straight line having a cross-sectional laterally concave shape formed on the left rack side surface 364L and the right rack side surface 364R of the rack 364 along the longitudinal axis of the rack 364. A right guide groove 374R formed on the right rack side surface 364R and a left guide groove 374L formed on the left rack side surface 364L. In other words, the rack 364 has an I-shaped cross section with a constricted portion 370 in the middle. However, the guided portion 374 may be provided only in one of the right guide groove 374R and the left guide groove 374L if sufficient. In addition, a ridge can be formed instead of the groove, and a groove for guiding the ridge can be formed on the guide portion 376 side. In addition, the guide portion 376 may have a box shape surrounding the four surfaces of the rack 364. In this case, a portion corresponding to the tooth 372 is opened, and a pinion gear 362 is inserted into the opening to engage with the tooth 372 of the rack 364.

Next, the guide part 376 will be described. The guide portion 376 has a function of guiding the rack 364 to a predetermined position by a predetermined trajectory by guiding the guided portion 374, and is configured by a guide rail 378 in the tenth embodiment. The guide portion 376 is integrally formed on the second substrate 356 or formed separately, and is fixed to the second substrate 356 by bonding or the like. The guide rail 378 in the tenth embodiment is formed in a guide body 382 having a rectangular prism shape and a square C cross section. As shown in FIG. 23 (E), the guide body 382 includes a bottom wall 382B, a left side wall 382L, a right side wall 382R, and a left guide rail 378L and a right guide rail 378R constituting the top wall 382U in a hollow quadrangular column. Thus, a hollow section 384 having a square cross section is formed. The left guide rail 378L and the right guide rail 378R are flat left protrusions and right protrusions that protrude from the upper ends of the left and right side walls 382L and 382R to face each other with a certain distance larger than the constricted portion 370 of the rack 364. A slit-shaped moving opening 380 is formed by the protrusion. With these configurations, the lower portion of the rack 364 is inserted into the hollow portion 384, the left guide rail 378L is disposed in the left guide groove 374L, and the right guide rail 378R is disposed in the right guide groove 374R. In other words, the constricted portion 370 is located in the moving opening 380, the upper portion of the rack 364, that is, the teeth 372 are located outside the guide body 382, and the rack 364 is guided by the guide rail 378 and straight in the longitudinal direction thereof. Can be moved. In other words, the rack 364 is guided by the guide rail 378 and can move in parallel with the second substrate 356, and one end, that is, the lower end thereof is arranged to face the switch lever 144. In other words, the switch lever 144 is directly pushed by the rack 364 and can be moved from the connected state CS to the disconnected state AS. However, the movement of the switch lever 144 by the rack 364 may be indirectly performed via the connector 168 as in the first embodiment.

Next, the rack movement regulating device 384 will be described mainly with reference to FIGS.
The rack movement restricting device 384 has a function of restricting the amount of movement of the rack 364, in other words, a function of restricting the relative position of the rack 364 with respect to the guide portion 376. A forward limit device 388 is included. However, either one of the backward restriction device 386 and the forward restriction device 388 may be used, or the rack movement restriction device 384 may not be provided.

  First, the reverse regulating device 386 will be described. The retreat restricting device 386 is configured by a retreat restricting pin 392 that protrudes from the left and right side surfaces of the intermediate portion of the rack 364 and a lower end edge 382B of the guide body 382 that is the guide portion 376 on the switch lever 144 side. In the tenth embodiment, the rack 364 includes a left retraction restricting pin 392L protruding from the left rack side surface 364L, a right retreat restricting pin 392R protruding from the right rack side surface 364R, and a lower end edge 382B. With this configuration, the upward movement of the rack 364 in FIG. 24 is restricted by the left retreat restricting pin 392L and the right retreat restricting pin 392R coming into contact with the lower end edge 382B. In other words, the movement of the rack 364 in the direction away from the switch lever 144 is restricted by the retreat restricting device 386, and the lower end of the rack 364 does not move away from the switch lever 144 more than necessary. The retracted position of the rack 364 is positioned slightly above the switch lever 144 positioned in the connected state CS, and does not hinder the movement of the switch lever 144. Note that only one of the left backward restriction pin 392L and the right backward restriction pin 392R may be provided.

Next, the advance restriction device 388 will be described. The rack 364 is configured by the forward restricting pins 394 protruding from the left and right side surfaces of the upper end portion of the rack 364 and the upper end edge 382T of the guide body 382 as the guide portion 376 on the side opposite to the switch lever 144. The tenth embodiment includes a left advance restriction pin 394L protruding from the left rack side surface 364L of the rack 364, a right advance restriction pin 394R protruding from the right rack side surface 364R, and an upper end edge 382T. With this configuration, the downward movement of the rack 364 in FIG. 24 is restricted by the left advance restriction pin 394L and the right advance restriction pin 394R coming into contact with the upper edge 382T. In other words, the movement of the rack 364 in the direction approaching the switch lever 144 is restricted by the forward restriction device 388, and the lower end of the rack 364 does not move the switch lever 144 more than necessary.
With these configurations, the rack 364 moves until the left advance restriction pin 394L and the right advance restriction pin 394R are stopped by the upper edge 382T by the rotation of the pinion gear 362 in FIG. The switch lever 144 can be rotated from the connected state CS to the disconnected state AS by the front end (lower end) of the rack 364, and the counterclockwise rotation restriction pin 392L and the right advancement restriction pin 392R are rotated by the counterclockwise rotation of the pinion gear 362. The movement is stopped until the movement is stopped by 382B, in other words, the tip of the rack 364 is restricted to stop at a position slightly away from the position of the switch lever 144 in the connected state CS.

Next, the seismic device 354 will be described with reference to FIGS.
The seismic sensing device 354 has a function of detecting a seismic intensity of at least a predetermined value in the event of an earthquake. If the seismic intensity is 5 or higher, an earthquake signal AS is output. The seismic sensing device 354 according to the tenth embodiment roughly includes a seismic intensity detector 402, a seismic intensity detector mounting device 404, and a level 406. However, the level 406 is a portable type and does not have to be attached to the seismic sensing device 354. Moreover, the seismic sensing device 354 can be changed to another mechanism having the same function.

First, the seismic intensity detector 402 will be described.
The seismic intensity detector 402 has a function of outputting an earthquake signal AS when a seismic intensity of at least a predetermined value is detected. In the tenth embodiment, the mechanical seismic intensity detector 408 is employed, and the mechanical seismic intensity detector 408 includes a vertical seismic intensity detector 412 for detecting the seismic intensity of the P wave and a lateral seismic intensity detector 414 for detecting the seismic intensity of the S wave. The seismic intensity detector 402 can be mounted integrally with the second substrate 356 or on a vertical wall 460 near the distribution board 100 that is completely different from the second substrate 356.

Next, the longitudinal seismic intensity detection device 412 will be described with reference to FIG.
The vertical seismic intensity detection device 412 has a function of detecting a P wave, that is, a seismic intensity equal to or higher than a predetermined value in a vertical vertical vibration with respect to a horizon that arrives in advance. And a vertical guide 418.
Longitudinal seismic intensity detector 412 is disposed within the casing of mechanical seismic intensity detector 408, and has an upper end attached to a fixed part (not shown) and a lower end suspended from a spherical weight 415 made of conductive metal. A spindle type seismometer using a metal spring 416 is used. The weight 415 is disposed in a vertically suspended movement space 422 substantially surrounded by the four sides of the vertical guide 418 in a freely suspended state, and the lateral movement is restricted by the wall surface of the vertical guide 418, It is arranged so as to be movable freely in the vertical direction substantially. In a state where the weight 415 is freely suspended, a perpendicular passing through the center of the spring 416 and the weight 415 is disposed so as to overlap with a perpendicular VL passing through the center of a fulcrum screw 466 described later when viewed from the front. At the bottom of the vertical movement space 422, the lower electrode 424L is disposed at a distance where the weight 415 comes into contact with the weight 415 when the weight 415 moves in the vertical direction due to an S wave with a seismic intensity of 5 strength. Therefore, the seismic intensity to be detected can be changed by changing the distance between the weight 415 and the lower electrode 424L. The spring 416 functions as the upper electrode 424U. A first lead wire 426L is drawn from the lower electrode 424L, and a second lead wire 426U is drawn from the upper electrode 424U, and is connected to the control device 166. Specifically, for example, when the second lead wire 426U is connected to the positive electrode of the DC power source, the first lead wire 426U is connected to the negative electrode, and the weight 415 contacts the lower electrode 424L, the current is passed through them. Since this flows, let this current be the earthquake signal AS. When the vertical vibration is caused by the earthquake, the vertical seismic intensity detection device 412 swings in the vertical direction, so that the weight 415 vibrates up and down via the spring 412. When the magnitude of the earthquake is greater than 5 seismic intensity, the amplitude of the weight 415 increases and comes into contact with the lower electrode 424L, and the earthquake signal AS is output as described above.

Next, the seismic intensity detection device 414 will be described mainly with reference to FIG.
The lateral seismic intensity detection device 414 has a function of detecting seismic intensity equal to or greater than a predetermined value in the rolling parallel to the horizontal line arriving after the S wave, that is, the P wave. In the tenth embodiment, mechanical seismic intensity detection is performed. It is arranged in the housing of the device 408, and includes an inverted L-shaped lateral seismic intensity attachment portion 426, a seismic oscillator 428, and a detector 432.
First, the lateral seismic intensity attachment portion 426 will be described.
The seismic intensity attachment portion 426 has a function that the seismic swinging body 428 is suspended so as to be swingable in all lateral directions. In the tenth embodiment, the conductive plate material is bent to form an inverted L shape. A mounting ring 434 protruding downward from the horizontal portion 426H is formed. The upper end of the seismic rocking body 428 is locked to the mounting ring 434 so as to be rockable in all directions.
Next, the seismic oscillator 428 will be described.
The seismic rocking body 428 has a function of determining the amount of shaking in proportion to the magnitude of the S wave. In the tenth embodiment, a conical weight 436 is formed at the lower end, and The suspension bar 442 extends linearly upward and has a circular hook 438 formed at the upper end. The circular hook 438 is locked to the mounting ring 428. As a result, the seismic oscillator 428 can swing in all directions in proportion to the magnitude of the S wave.
Next, the detection body 432 will be described.
The detection body 432 has a function of detecting that the seismic rocking body 428 rocks in the lateral direction by a predetermined amount or more. In the tenth embodiment, the horizontal portion 442H of the L-shaped lateral vibration detection body 442 has a circular shape. The detection hole 444 is formed. The lower end portion of the seismic rocking body 428 is inserted into the detection hole 444. The conical weight 436 is set to be located at the center of the detection hole 444 in a state where the seismic oscillator 428 is suspended by gravity.
A third lead wire 446 is connected to the seismic intensity attachment portion 426, and a fourth lead wire 448 is connected to the detection body 432 and connected to the control device 166. Specifically, for example, when the third lead wire 446 is connected to the positive electrode of the DC power source, the fourth lead wire 448 is connected to the negative electrode, and the conical weight 436 is in contact with the lateral vibration detector 442, the third lead wire 446 is connected to the negative electrode. This current is output as an earthquake signal AS. When a roll is caused by an earthquake, the seismic oscillator 428 swings in the horizontal direction. Therefore, when the magnitude of the earthquake is greater than 5 seismic intensity, the amplitude of the conical weight 436 increases and comes into contact with the detection ring 432. As described above, the earthquake signal AS is output. In a state where the seismic oscillator 428 is freely suspended, a perpendicular passing through the center of the seismic oscillator 428 is disposed so as to overlap with a perpendicular VL passing through the center of a fulcrum screw 466 described later when viewed from the front.

Next, the seismic intensity detector mounting device 404 will be described mainly with reference to FIG.
The seismic intensity detector mounting device 404 has a function of adjusting the attitude of the seismic intensity detector 402 so that the seismic intensity detector 402 can properly detect both the vertical seismic intensity and the horizontal seismic intensity. A Z-direction adjusting device 454 and an X-direction adjusting device 456 are included.
First, the adjustment substrate 452 will be described.
The adjustment board 452 has a function of fixing the seismic intensity detector 402 and changing the posture of the seismic intensity detector 402. In the tenth embodiment, the adjustment board 452 and the adjustment plate 458 extending in the vertical direction are arranged in the horizontal direction. The extending fixed plate 462 is formed in an approximately L shape. The seismic intensity detector 402 is fixed to the upper surface of the fixed plate 462. The upper end of the adjustment substrate 452 is fixed to the wall surface 460 that is suspended by the Z-direction adjusting device 454 so that the distance from the wall surface 460 can be adjusted, and further, the adjustment substrate 452 can be rotated in the vertical surface. This is because the mechanical seismic intensity detector 408 built in the seismic intensity detector 402 adjusts its posture so that it can accurately detect the seismic intensity. Specifically, the weight 415 in the vertical seismic intensity detection device 412 is not substantially in contact with the wall surface of the vertical guide 418, and the lower end of the conical weight 436 in the horizontal seismic intensity mounting portion 426 is the center of the detection hole 444. The attitude of the seismic intensity detector 402 is adjusted so that

Next, the Z direction adjusting device 454 will be described.
The Z direction adjusting device 454 has a function of adjusting the adjustment substrate 452 in the Z direction.
The Z direction refers to the lateral direction with respect to the wall surface 460. In other words, the adjustment substrate 452 has a function of adjusting the distance to the wall surface 460 by moving the upper end portion of the adjustment substrate 452 closer to or away from the wall surface 460. And an adjustment sleeve 465 having an outer screw 462 formed on the outer peripheral surface and a hexagon nut 464 for rotation at the end, and a fulcrum screw 466 that penetrates the adjustment sleeve 465 and is planted on the wall 460. , And a nut 468 that is screwed into the external screw 462 and integrated with the upper end of the adjustment substrate 452. The tip of the adjustment sleeve 465 is abutted against the wall surface 460. In this configuration, when the adjustment sleeve 465 is rotated in a predetermined direction via the hexagon nut portion 464, the nut 468 rotates relative to the adjustment sleeve 465, so that the nut 468 is moved in the axial direction of the adjustment sleeve 465. The In other words, since the upper end portion of the adjustment board 452 approaches or moves away from the wall surface 460, the adjustment board 452 is moved to the right in FIG. 25B according to the rotation direction of the adjustment sleeve 465, or As a result, the inclination of the adjustment board 452 with respect to the vertical line VL passing through the center of the fulcrum screw 466, and thus the inclination of the fixing plate 462 with respect to the horizontal line is changed, so that the attitude detector 402 in the Z direction is changed. Is changed.

Next, the X direction adjusting device 456 will be described.
The X-direction adjusting device 456 has a function of adjusting the posture of the adjustment board 452 in the X direction in FIG. 25A. In the tenth embodiment, the X-direction adjustment apparatus 456 Long holes 472L and 472R extending in the direction and a pair of screws 474L and 474R that pass through the long holes 472L and 472R and are screwed into the wall surface 460 are included. The X direction refers to a moving direction in a plane parallel to the wall surface 460, that is, an arrow direction in FIG. With this configuration, the adjustment substrate 452 can be rotated around the fulcrum screw 466 in a plane approximately parallel to the wall surface 460 in the range of the holes 472L and 472R. Then, by tightening the screws 474L and 474R at an appropriate position on the adjustment board 452, the posture in the X direction of the seismic intensity detector 402 is fixed in a changed state.

Next, the level 406 will be described with reference to FIG.
The level 406 has a function to display that the mechanical seismic intensity detector 408 has been adjusted to a position suitable for measuring seismic intensity. Specifically, the weight 415 and the conical weight 436 detect the above-mentioned seismic intensity. It has a function to indirectly display that it is in an appropriate posture. However, it can be changed to another apparatus having the same function, for example, a bubble tube type or a laser level. In the tenth embodiment, a lower vibration device 475 is used as the level 406. This is because the lower vibration device 475 is easy to see and inexpensive.
The lower vibration device 475 in the tenth embodiment includes a lower vibration body 476 and a lower vibration body 478.

First, the lower vibration body 476 will be described.
The lower vibration body 476 holds the lower vibration body 478 so that it can be suspended by gravity, and has a function of confirming the inclination of the lower vibration body 476 with respect to the vertical.In the tenth embodiment, it is a lateral channel type, A downward swing attachment portion 476U that protrudes laterally from the upper end of the vertical attachment portion 476V, and a downward swing visual recognition portion 476B that protrudes laterally in parallel with the downward swing attachment portion 476U from the lower end are formed. The lower swing visually recognizing part 476B is formed with a lower swing position visually recognizing hole 482 in which the lower end portion of the circular lower swing body 478 hangs down. In the tenth embodiment, the vertical attachment portion 476V is directly attached to the seismic intensity detector 402, but may be attached to a part integrated with the seismic intensity detector 402.

Next, the lower vibration body 478 will be described.
The lower vibration body 478 has a function of hanging down by its own weight. In the tenth embodiment, the lower vibration body 478 is linked by a thin thread (not shown) penetrating a through-hole formed in the diameter portion of the small-diameter sphere 483. The upper end of the lower swing attachment portion 476U is slidably attached at a predetermined position, and the lower end portion penetrates the lower swing position visual recognition hole 482. With this configuration, the lower vibration body 478 is suspended from the lower vibration mounting portion 476U by gravity, so that the lower end of the lower vibration body 478 is located in the circular lower vibration position visualizing hole 482, and the seismic intensity detection to which the lower vibration body 476 is attached. If the device 402 is in the vertical state, the lower end of the lower vibration body 478 is located at the center of the lower vibration position visual recognition hole 482. In other words, the distance between the lower end of the lower vibration body 478 and the inner peripheral edge of the lower vibration position visual recognition hole 482 is equal in the entire circumference. That is, it means that the weight 415 of the vertical seismic intensity detector 412 in the seismic intensity detector 402 and the conical weight 436 of the lateral seismic intensity detector 414 are set to a state in which the seismic intensity can be accurately detected. However, when the seismic intensity detector 402 is inclined, the lower end portion of the lower vibration body 478 is displaced from the center of the lower vibration position visual recognition hole 482. In other words, the distance between the lower end portion of the lower vibration body 478 and the inner peripheral edge of the lower vibration position visual recognition hole 482 is large in some portions, small in other portions, and not equal over the entire circumference. In this case, the attitude of the seismic intensity detector 402 is adjusted by the aforementioned Z direction adjusting device 454 or X direction adjusting device 456 so that the lower end of the lower vibration body 478 is positioned at the center of the lower vibration position visual recognition hole 482. .

Next, the control device 166 will be described with reference to FIG.
In order to distinguish from the control device 166 of the sixth embodiment, the control device 166 is referred to as a second control device 353 in the tenth embodiment.
In addition to the function of the control device 166 in the sixth embodiment, the second control device 353 activates the ampere breaker 128 by operating the actuator 164 and therefore the second actuator 360 when the seismic signal AS is output from the seismic sensing device 354. In the disconnected state AS and when the release switch 486 is closed, it has a function of interrupting and resetting the process of operating the second actuator 360, and a function of canceling the alarm from the speaker 484. The same parts as those in the sixth embodiment shown in FIG. 14 are denoted by the same reference numerals and description thereof is omitted, and different configurations will be described. When the earthquake signal AS from the seismic device 354 is input to the microcomputer 290, the cancellation is further canceled. When the switch 486 is connected and the release switch 486 is pressed and closed, a release signal OS is input and a speaker 484 that emits an alarm sound is provided. Siren, music, etc. are used as the alarm sound, but it is preferable to adopt a siren tone to represent the degree of tension, and in order to represent the tension time, continuous sound, intermittent sound, or proportional to the remaining time Thus, it is preferable to use a variable intermittent sound that shortens the intermittent interval.

Next, the operation of the tenth embodiment will be described with reference to the flowchart of FIG. 29 and the timing chart of FIG.
When a power failure is detected, in other words, when the alternating signal ACS is not output, the description is omitted because it is the same as the processing of the sixth embodiment.
First, in step S21, it is determined whether or not the seismic signal AS is output from the seismic sensing device 354. If it is not output, the process proceeds to step S22. If it is output, the process proceeds to step S28 described later.

  Next, in step S22, it is determined whether or not the alternating signal ACS is output from the operational amplifier 174. If it is not output, the process proceeds to step S23, and if it is output, the process returns to step S21 to enter a standby state. In other words, if the seismic signal AS is not output, an earthquake with a predetermined seismic intensity or more has not occurred, and if a voltage is applied to the input line 148, there is no power failure, so the first detection piece 172A, The alternating signal ACS is always output based on the detection in the two detection pieces 172B. In other words, this state is a normal state.

  In step S21, if the seismic sensing device 354 detects a longitudinal vibration or a lateral vibration having a seismic intensity of 5 or more, in other words, if the weight 415 in the vertical seismic intensity detecting device 412 contacts the lower electrode 424L, a current is generated between them. Therefore, when the conical weight 436 in the lateral seismic intensity detection device 414 comes into contact with the detection body 432, the current flows between them because the current flows as shown in FIG. Is output as the earthquake signal AS (FIG. 30A), and the process proceeds to step S28.

If the alternating signal ACS is not detected in step S22, in other words, if a power failure occurs, the process proceeds to step S23.

In step S23, after issuing an alarm from the speaker 484, the process proceeds to step S24. This alarm is, for example, an intermittent sound.

In step S24, it is determined whether the alternating signal ACS is output again. If it is output, the process proceeds to step S25, and if it is not output, the process proceeds to step S26.

In step S26, timing of the temporary suspension rejection time TS is started, and it is determined whether the temporary suspension rejection time TS has elapsed. If not, the processing returns to step S24, and if it has elapsed, the processing proceeds to step S27.

In step S25, the alarm started in step S23 is canceled. In other words, the sound generation from the speaker 484 is stopped, and then the process returns to step S21.

The temporary stop time TS in step S26 can be appropriately adjusted, for example, between 1 second and 180 seconds. By providing the step of re-detecting the alternating signal ACS at the temporary stop time TS, the operation of the second actuator 360 based on a temporary power failure can be automatically avoided, and unnecessary disconnection of the ampere breaker 128 can be prevented. is there. This is because, in rare cases, the voltage may temporarily drop in the input line 148, thereby preventing the automatic break of the ampere breaker 128 based on this. In this sense, the pause time is preferably set to 180 seconds equal to the delay time.

In step S27, the power failure signal PFS is output and the process proceeds to step S31.
When the earthquake signal AS is output, start counting the first predetermined time T1 in step S28 (Fig. 30C). If not counting the first predetermined time T1, proceed to step S29 and time the first predetermined time T1. If so, the process proceeds to step S31. The first predetermined time T1 is a function of delaying the first predetermined time T1 without operating the second actuator 360 immediately and shutting off the ampere breaker 128 when a seismic intensity of 5 is detected. This is because it has a function of ensuring illumination for a predetermined time T1, thereby enabling smooth evacuation at night, for example. The first predetermined time T1 is, for example, 3 minutes. When 2 minutes and 30 seconds have elapsed from the start, an intermediate signal is output, and when the time is 3 minutes, the process proceeds to step S31. The time of the first predetermined time T1 can be set as appropriate, but is preferably set to 3 minutes to 5 minutes in consideration of the occurrence of secondary disasters such as evacuation and fire caused by electric appliances.

  In step S29, an alarm is issued for the first predetermined time T1. For example, during 2 minutes and 30 seconds from the speaker 484 to the intermediate signal at the first predetermined time T1, a loud intermittent sound is generated to notify that an earthquake with a seismic intensity of 5 or more has occurred and to evacuate, and to After the signal is output, by changing to continuous sound, the ampere breaker 128 is cut off, so that it is possible to grasp sensibly that the lighting is imminent, and then the process proceeds to step S30 (FIG. 30). D).

In step S30 at the timing when the alarm is issued, it is determined whether the release signal OS due to the release switch 486 being closed is output.If the release signal OS is determined, the process returns to step S21. Return to S28. In other words, if an earthquake exceeding seismic intensity 5 occurred, but it was determined that the shaking stopped immediately and the ampere breaker 128 could not be dropped, pressing the release switch 486 interrupted the process of shutting off the ampere breaker 128 once started. Can be made.
Therefore, the actuator activation signal AOS is not output, and the actuator 164 and thus the electric motor 184 are not activated. In other words, even if an earthquake with a seismic intensity of 5 or higher occurs, the electric device 121 is supplied with power during the first predetermined time T1, so that it is possible to secure lighting necessary for evacuation.

In step S28, when the first predetermined time T1 is measured, the process proceeds to step S31.

In step S31, after the actuator operation signal AOS is output, the process proceeds to step S32.

In step S32, timing of the second predetermined time T2 is started. If the second predetermined time T2 is not timed, step S32 is looped. If the second predetermined time T2 is timed, the process proceeds to step S33.

In step S33, the output of the actuator operation signal AOS is stopped, and the process proceeds to step S34. Therefore, the electric motor 184 is rotated for the second predetermined time T2 (FIG. 30). Therefore, the second predetermined time T2 is set to a time sufficient to turn the switch lever 144 from the connected state CS to the disconnected state AS. Thus, while the actuator operation signal AOS is being output, a voltage is applied to the base of the first transistor 292T, so that the first transistor 292T is energized, the electric motor 184 rotates in the forward direction, Since the pinion gear 362 is rotated clockwise in FIG. 24 via the gear reducer 358, the rack 364 is moved downward via the teeth 372 meshing with the pinion gear 362, and the switch breaker 144 is pushed down to lower the ampere breaker. 128 is switched from the connected state CS to the disconnected state AS (FIG. 30). Therefore, the voltage on the output side of the ampere breaker 128 becomes zero regardless of the voltage on the input side (FIG. 30K). Since the second predetermined time T2 is sufficient to switch the switch lever 144 to the cut state AS, the electric motor 184 is rotated even after the switch lever 144 is switched to the cut state AS, so that the rack 364 is further moved. The However, the movement of the rack 364 is stopped when the advance restriction pin 394 integrated with the rack 364 contacts the upper end edge 382T of the guide body 382. In this case, the electric motor 184 is forcibly stopped from rotating, but even in this case, the second predetermined time T2 is set so that the electric motor 184 does not cause troubles such as burning.
When the power is restored or when the power is continuously supplied, the alternating signal ACS is output from the operational amplifier 174, so that the output of the operational amplifier 174 becomes the power recovery signal RPS.

  If the power recovery signal RPS is detected in step S34, the process proceeds to step S35. If the power recovery signal RPS is not detected, step S34 is looped. That is, the standby state is maintained until the power recovery signal RPS is detected.

In step S35, the LED lighting signal ALS is output, and the process proceeds to step S36.
As a result, while the LED lighting signal ALS is output, a voltage is supplied to the base of the second transistor 294T, the second transistor 294T is energized, and the LED 296 emits light and is visually informed that power has been restored. To do. However, the notification of power recovery can also be made by visual notification or sound notification.

  In step S36, the measurement of the third predetermined time T3 is started. If the third predetermined time T3 has not elapsed, the process proceeds to step S37. If the measurement of the third predetermined time T3 is completed, the process proceeds to step S38. The third predetermined time T3 is a time sufficient to return the rack 364 to the position where the rack 364 does not interfere even when the switch lever 144 is returned to the connected state CS by the reverse rotation of the electric motor 184, and is not too long. Set to In other words, it is sufficient time for the backward movement restriction pin 392 to stop moving to the lower edge 382B of the guide body 382, and after the backward movement restriction pin 392 is prevented from moving by the lower edge 382B, the movement is further reversed for a minute time. The time is set so as not to adversely affect the electric motor 184.

In step S37, the electric motor 184 is driven in reverse and the process returns to step S36. That is, the electric motor 184 is reversely rotated for the third predetermined time T3, and this reverse rotation causes the pinion gear 362 to rotate counterclockwise in FIG. 24, so that the rack 364 is moved upward and the retraction regulating pin 392 is moved to the guide body. It abuts against the lower edge 382B of 382 and is prevented from moving. Immediately after this movement is blocked, the third predetermined time T3 is counted, and the process proceeds to step S38. Note that the step of automatically returning the rack 364 in steps S36 and S37 can be omitted. This is because the rack 364 can be manually pushed upward by employing the spur gear reducer 358.
The administrator perceives power recovery by the light emission of the LED 296, confirms the safety of each electrical device 121, and then presses the recovery switch 298 to output the recovery signal RS.

If the recovery signal RS is detected in step S38, the process proceeds to step S39. If the recovery signal RS is not detected, the process loops through step S38 and waits until the recovery switch 298 is pressed. Therefore, after confirming the safety of each electrical device 121 such as whether the combustible material is in contact with the electrical heating device, the administrator closes the recovery switch 298 and outputs the recovery signal RS, and then switches the ampere breaker 128. The lever 144 is returned to the connected state CS. As a result, secondary disasters such as fire due to power recovery can be prevented.
In step S39, the output of the LED lighting signal ALS is stopped and the process is terminated.
When a power failure occurs, the power failure signal PFS operates in the same manner as described in the sixth embodiment, and the switch lever 144 of the ampere breaker 128 is switched to the disconnected state AS. Note that the recovery switch 298 can be replaced by a release switch 486.
