(Embodiment 1)
As shown in FIG. 1, the collective switching device 1 according to this embodiment includes a plurality of branch breakers 31, 32,... 3 n corresponding to a plurality of branch circuits 21, 22,. It is arranged adjacent to the housed distribution board 4. The collective switching device 1 includes a contact device 11 and a switch device 12 that switches between a closed state and an open state of the contact device 11. The contact device 11 has at least one of a plurality of branch breakers 31, 32,... 3n as a target breaker, and a branch circuit corresponding to the target breaker among a plurality of branch circuits 21, 22,. It is inserted between the target breaker and the target circuit.

  In the example of FIG. 1, the collective switching device 1 includes a plurality of branch breakers 31, 32,..., 3n, a first branch breaker 31, a second branch breaker 32,. The branch breaker 3n is the target breaker. Therefore, the target circuit corresponds to the n-th branch breaker 3n among the first branch circuit 21, the second branch circuit 22,..., The n-th branch circuit n, which are a plurality of branch circuits 21, 22,. The n-th branch circuit 2n.

  In the following, when each of the plurality of branch breakers 31, 32,... 3n is not particularly distinguished, they are collectively referred to as “branch breaker 3”, and when each of the plurality of branch circuits 21, 22,. This is called “branch circuit 2”.

  Moreover, it is desirable that the distribution board device 10 according to the present embodiment includes the collective switching device 1 and the distribution board 4 described above. That is, the collective opening / closing device 1 constitutes the distribution board device 10 integrated with the distribution board 4 by being provided integrally with the board body 41 of the distribution board 4.

  Hereinafter, the collective switchgear 1 and the distribution board device 10 according to the present embodiment will be described in detail. Although this embodiment demonstrates as an example the case where the collective switchgear 1 is introduce | transduced into a general detached house in China, it is not the meaning which limits the use area of the collective switchgear 1 to China. Moreover, the collective opening / closing device 1 can be introduced not only in a detached house but also in each dwelling unit of a collective housing, a store, an office, a factory, or the like.

  As shown in FIG. 1, in the collective switching device 1 according to the present embodiment, a switch device 12 is provided separately from the contact device 11. Further, the contact device 11 constitutes a relay device 14 together with the control unit 13. The control unit 13 is configured to switch between the closed state and the open state of the contact device 11 when the switch device 12 is switched on and off. Here, the relay device 14 is configured such that the control unit 13 switches between a closed state and an open state of the contact device 11 in accordance with a control signal from the outside, and this control signal switches the switch device 12 on and off. It changes with.

  The relay device 14 has a primary side terminal 141 (see FIG. 4) and a secondary side terminal 142 (see FIG. 4). The primary side terminal 141 is connected to the target breaker 3n, and the secondary side terminal 142 has a target. Circuit 2n is connected. The relay device 14 has the contact device 11 inserted between the primary side terminal 141 and the secondary side terminal 142 in the container 143 (see FIG. 4), and the control unit 13 opens the contact device 11. The state and the closed state are switched.

  Since the contact device 11 in the relay device 14 is inserted between the target breaker 3n and the corresponding target circuit 2n as described above, the target breaker 3n is switched with the switching of the switch device 12 on and off. -The target circuit 2n is electrically connected or disconnected. That is, if the contact device 11 is in the closed state, the target breaker 3n and the target circuit 2n are electrically connected, and if the contact device 11 is in the open state, the target breaker 3n and the target circuit 2n are disconnected.

  Further, the switch device 12 switches on and off according to the operation of the timer unit 121 that switches on and off at a preset time, the operation element 122 that receives a user's manual operation, and the operation element 122. And an opening / closing mechanism 123. That is, the switch device 12 automatically switches on and off of a contact (not shown) when the time set in advance by the timer unit 121 is reached. The contact is manually switched on and off. In other words, the switch device 12 is a timer switch configured to be capable of automatic operation by the timer unit 121 in addition to manual operation.

  Here, the timer unit 121 sets an “on time” and an “off time” in advance by a setting unit (not shown), and turns on the contact of the switch device 12 when the current time becomes the “on time”. When the time reaches the “off time”, the contact of the switch device 12 is turned off. The “on time” and “off time” can be arbitrarily set (changed) by the user operating the setting unit.

  The operation element 122 is an operation handle for the user to operate the switch device 12. The switch device 12 may be a switch that is turned on and off every time the operation element 122 is pressed, such as a so-called piano handle type switch, or may be turned on and off depending on the inclination of the operation element 122, such as a seesaw switch. May be a switch that inverts. The switch device 12 may be a general switch used for a wall switch or the like.

  The relay device 14 is connected to the switch device 12. Here, the contact device 11 is closed when the switch device 12 is on, and the contact device 11 is opened when the switch device 12 is off. It is configured. In the present embodiment, the relay device 14 switches between the closed state and the open state of the contact device 11 in accordance with a control signal from the outside. A configuration in which a control signal is transmitted from the device 12 by wireless communication may be employed.

  With the configuration as described above, the collective switching device 1 is energized to the branch circuit (target circuit) 2n connected to the target breaker 3n by switching the contact device 11 between the closed state and the open state by the switch device 12. Can be shut off and restored at once. Here, when the target circuit includes a wiring device such as an outlet, it is desirable that the decorative plate of these wiring devices has the same color as the switch device 12 and can be distinguished from other wiring devices. Thereby, the user can easily identify which wiring appliance (outlet) in the house is interrupted by the collective switching device 1.

  In the present embodiment, the collective switching device 1 further includes a display unit 15 that displays whether the contact device 11 is in a closed state or an open state, as shown in FIG. Here, the display unit 15 includes an LED (light emitting diode) that receives an output from the switch device 12 and changes its lighting state between when the contact device 11 is in a closed state and when the contact device 11 is in an open state. For example, the display unit 15 lights red when the contact device 11 is in the closed state, and lights green when the contact device 11 is in the open state.

  The display unit 15 is not limited to this example. For example, the display unit 15 may be turned on when the contact device 11 is in the open state, turned off when the contact device 11 is in the closed state, or may be displayed with a blinking pattern. . The display unit 15 may be integrated with the switch device 12. In this case, a switch having a function of displaying whether the so-called pilot switch or firefly switch is turned on or off is used as the switch device 12, thereby simplifying the configuration as compared with the case where the display unit 15 is separately provided. be able to.

  Next, the configuration of the distribution board 4 in which the collective switchgear 1 having the above-described configuration is disposed adjacently will be described.

  As shown in FIG. 1, the distribution board 4 houses a main circuit breaker 42 inserted in the main electric circuit in addition to a plurality of branch breakers 31, 32,.

  The main breaker 42 has a primary side terminal 421 (see FIG. 4) and a secondary side terminal 422 (see FIG. 4). A commercial power source (power system) 5 is connected to the primary side terminal 421, and a secondary side terminal. A plurality of branch breakers 31, 32,..., 3n are connected to 422. In China, the single-phase two-wire system and the three-phase four-wire system are used as the power distribution system, but here the power from the commercial power source 5 is distributed to the house with a single-phase two-wire system of 220V. An explanation will be given.

  The main breaker 42 has a contact (not shown) inserted between the primary side terminal 421 and the secondary side terminal 422 in the body 423 (see FIG. 4), for example, an overload current or a short circuit. Trips when an abnormality such as current or leakage occurs. Further, the main breaker 42 has an operation lever 424 (see FIG. 4), and the user can manually switch between the open state and the closed state by operating the operation lever 424.

The primary side terminal 301 is connected to the secondary side terminal 422 of the main breaker 42, and the secondary breaker The branch circuit 2 corresponding to each is connected to the side terminal 302. Here, the first branch circuit 21 corresponds to the first branch breaker 31, the second branch circuit 22 corresponds to the second branch breaker 32, and the third branch breaker 33 corresponds to the third branch breaker 33. The branch circuit 23 corresponds. The n-th branch circuit 2n corresponds to the n-th branch circuit breaker 3n. In FIG. 1, since the n-th branch circuit breaker 3n is the target circuit breaker, the n-th branch circuit 2n is connected to the n-th branch circuit (target circuit) 2n. The contact device 11 of the collective switching device 1 is inserted.

  The branch breaker 3 has a contact (not shown) inserted between the primary side terminal 301 and the secondary side terminal 302 in the container 303 (see FIG. 4), for example, an overload current or a short circuit. Trips when an abnormality such as current or leakage occurs. Further, the branch breaker 3 has an operation lever 304 (see FIG. 4), and the user can manually switch between an open state and a closed state by operating the operation lever 304.

  As the branch breaker 3, here, an earth leakage circuit breaker (ELB: Earth Leakage Circuit Breaker) that has a function of breaking when there is a leakage and a circuit breaker (MCB: Molded Case Circuit Breaker) that does not have a function of breaking when there is a leakage are used. It has been. The earth leakage breaker is connected to two poles of a neutral line (N phase) and a voltage line (L phase), and the wiring breaker is connected to only one pole of the voltage line. For this reason, in the branch circuit 2 corresponding to the branch breaker 3 composed of the circuit breaker for wiring, only the voltage line is connected via the branch breaker 3, and the neutral line is not connected to the branch breaker 3 and the terminal block 71 (described later) 4).

  The branch breaker 3 composed of an earth leakage breaker has a test button 307 (see FIG. 4) operated by the user when checking the operation, and an abnormality display unit 308 (see FIG. 4) for displaying the presence / absence of an abnormal current. doing. The earth leakage circuit breaker is configured to forcibly create the same state as the earth leakage when the test button 307 is pressed in a steady state, and the test button is in a state where the interruption function is normally operated at the time of earth leakage. The contact opens when 307 is pushed. The abnormality display unit 308 visually notifies the user of the occurrence of electric leakage, for example, by switching the display color between a steady state and during electric leakage. Note that the branch breaker 3 made of the earth leakage breaker has substantially the same dimensions as the main breaker 42 and is formed to have a size approximately twice that of the branch breaker 3 made of the wiring breaker in the longitudinal direction of the mounting member 45 described later. Has been.

  The branch circuit 2 connected to the branch breaker 3 includes, as a load, one or more devices such as a lighting fixture or a hot water supply facility, and an outlet (outlet) of a plug connection device or a wall switch. The plurality of branch circuits 21, 22,... 2n may classify these loads according to installation locations (rooms) or the like, but here it is assumed that they are classified according to the type of load. Therefore, for example, a plurality of lighting fixtures are collectively connected to the same branch circuit 2, and a plurality of outlets are collectively connected to another branch circuit 2.

  As shown in FIGS. 2 and 3, the panel body 41 of the distribution board 4 is formed in a thin box shape in which the front view is a horizontally long rectangular shape, and is a wall (not shown) in the room (inside the building). Attached to. In Chinese houses, the distribution board 4 is generally installed near the entrance.

  As described above, the case 43 accommodates therein the terminal block 71 for connecting the neutral wire and the ground terminal block 72 for connecting the ground wire. The terminal block 71 is connected to the neutral line from the secondary terminal 422 of the main breaker 42, and the neutral line of the branch circuit 2 corresponding to the branch breaker 3 composed of the circuit breaker for wiring is connected. The neutral lines of these branch circuits 2 are connected to the main breaker 42.

  The main breaker 42 and the plurality of branch breakers 31 to 36 are fixed to the panel body 41 so as to be attached to the case 43 using a standardized attachment member 45. In the present embodiment, the mounting member 45 is a rail standardized by German Industrial Standards (DIN: Deutsche Industrie Normen), a so-called DIN rail, and the main breaker 42 and the plurality of branch breakers 31 to 36 are the same standard. Is compliant.

  Specifically, as shown in FIG. 4, the attachment member 45 is fixed to a pair of side plates 431 and 432 that are opposed to the longitudinal direction (lateral direction) of the case 43 at both ends in the longitudinal direction. It is constructed between the both ends of 43 of the longitudinal direction. The attachment member 45 is provided at the center of the case 43 in the short direction (vertical direction). The main breaker 42 and the plurality of branch breakers 31 to 36 are attached to the attachment member 45 so as to be aligned in the longitudinal direction of the attachment member 45. In addition, the attachment member 45 is provided along the back surface of the case 43 so that the protrusion amount from the front surface of the case 43 of the main breaker 42 and the plurality of branch breakers 31 to 36 is kept small.

  As shown in FIG. 5, the branch breaker 3 is provided with a recess 305 for fitting the mounting member 45 on the back surface of the vessel body 303, and is slidable with respect to the vessel body 303. A configuration having a holding lever 306 held is employed. The removal lever 306 is slidable along the back surface of the case 43 between a coupling position protruding from the inner surface of the recess 305 (the state shown in FIG. 5) and a release position retracted from the inner surface of the recess 305. . The branch breaker 3 is mechanically coupled to the mounting member 45 if the removal lever 306 is in the coupling position in a state where the mounting member 45 is inserted into the recess 305, and the mounting member 45 if the mounting lever 306 is in the release position. Is released from the mounting member 45.

  In FIG. 5, the attachment structure to the attachment member 45 is illustrated for the branch breaker 3 including the circuit breaker. However, the attachment structure to the attachment member 45 is also included in the branch breaker 3 including the earth leakage breaker and the main breaker 42. Is the same.

  As shown in FIG. 6, the cover 44 includes an inner cover 442 attached to the case 43 and a door 441 attached to the inner cover 442 so as to be opened and closed. The inner cover 442 has an opening hole 443 that is opened in a rectangular shape at a position covered by the door 441 when the door 441 is closed. Through the opening hole 443, the main breaker 42 and the plurality of branch breakers 31 to 36 are formed. A part of is exposed forward. The opening hole 443 is a position corresponding to the main breaker 42 and the plurality of branch breakers 31 to 36 in the inner cover 442 so as to expose at least the operation lever 424, the operation lever 304, the test button 307, and the abnormality display unit 308. It is formed in a simple shape.

  The door 441 rotates around a rotation axis (not shown) along the upper edge of the door 441 so that the door 441 has a closed position (a state shown in FIGS. 2 and 3) covering the opening hole 443 of the inner cover 442 and an opening hole 443. It moves between the open position (state of FIG. 6) to be exposed. The distribution board 4 normally uses the door body 442 in the closed position, and uses the door body 442 in the open position when checking the state of the main breaker 42 and the branch breaker 3, during recovery operation, or during maintenance. Is done. A knockout portion 444 is formed in the opening hole 443, and the opening hole 443 is opened according to the number of the main breakers 42 and the branch breakers 3 accommodated in the panel body 41 by breaking the knockout portion 444. The area can be adjusted.

  Next, the distribution board device 10 in which the collective switching device 1 is integrated with the distribution board 4 will be described.

  In the distribution board device 10 of this embodiment, the collective switching device 1 includes the switch device 12, the relay device 14, and the display unit 15 integrally with the panel body 41 of the distribution board 4 as described above.

  More specifically, the relay device 14 is formed to have substantially the same external dimensions as the branch breaker 3 composed of a circuit breaker for wiring. Further, as with the branch breaker 3, a standardized mounting member 45 is used. It is fixed to the panel main body 41 so as to be attached to the case 43. That is, the relay device 14 employs the same mounting structure as the branch breaker 3 illustrated in FIG. 5 as the mounting structure to the mounting member 45, and is detachably mounted on the case 43 of the panel body 41 from the case 43. ing.

  Further, a part of the relay device 14 is exposed forward through the opening hole 443 of the inner cover 442 in the same manner as the main breaker 42 and the plurality of branch breakers 31 to 36. The relay device 14 does not have a configuration corresponding to the operation lever 304 of the branch breaker 3.

  On the other hand, the switch device 12 and the display unit 15 are fixed to the panel main body 41 by a mounting structure different from the standardized mounting member (here, DIN rail) 45. That is, the switch device 12 and the display unit 15 are attached to the cover 44 instead of the case 43.

  Specifically, as shown in FIG. 6, the inner cover 442 has a mounting hole 445 that is opened in a rectangular shape at a position covered by the door 441 in a state where the door 441 is closed. The switch device 12 is attached to the inner cover 442 so that the rear portion is fitted into the attachment hole 445. Further, the inner cover 442 has a small hole (not shown) formed at a position covered by the door 441 in a state where the door 441 is closed, and the display unit 15 is configured so that the rear portion is fitted into the small hole. It is attached to the inner cover 442. The attachment hole 445 is formed on the side of the opening hole 443 (on the right side in FIG. 6), and the small hole is formed above the opening hole 443.

  The door 441 is formed with a window hole 46 at a position corresponding to the switch device 12 in a closed state. That is, the cover 44 is formed with a window hole 46 through which the switch device 12 of the collective opening / closing device 1 is exposed. Therefore, the user can operate the operation element (operation handle) 122 of the switch device 12 with the door 441 closed.

  Further, the door 441 has a display window 47 formed at a position corresponding to the display unit 15, and the user can visually recognize the display state of the display unit 15 while the door 441 is closed. It can be confirmed from the display state whether the contact device 11 is in the closed state or the open state.

  The collective switching device 1 of the present embodiment described above has a contact device 11 inserted between at least one branch breaker (target breaker) 3 and a corresponding branch circuit (target circuit) 2, and the contact device 11. And a switch device 12 for switching between the closed state and the open state. According to this configuration, the user can collectively cut off and restore the energization to the target branch circuit 2 simply by operating the switch device 12.

  Therefore, in order to reduce the standby power consumption in the electric equipment, the user operates the switch device 12 before going out to cut off the energization to the branch circuit 2 to which the electric equipment that is not used during absence is connected, What is necessary is just to operate switch device 12 again at the time of returning home, and to restore electricity supply. In short, the collective opening / closing device 1 of the present embodiment has an advantage that energization to a plurality of electric devices can be collectively controlled without the user pulling out the power plug from the outlet or directly operating the branch breaker 3. is there.

  Therefore, it is possible for the user to save time and effort and to prevent forgetting to unplug the power plug as compared to the case where the user unplugs the power plug every time he / she goes out. In addition, since the user only has to operate the switch device 12 in the same manner as operating a general wall switch, the user operates the branch breaker 3 in the distribution board 4 directly. I don't feel resistance.

  In addition, since the collective switching device 1 is disposed adjacent to the distribution board 4 in which a plurality of branch breakers 31, 32,... 3 n are housed in the board body 41, the collective switching device 1 is connected to the branch breaker 3 and the branch circuit 2. It is possible to reduce the labor of wiring work between. In particular, when the distribution board 4 is provided near the entrance, the collective opening / closing device 1 is also disposed near the entrance, so that the user can easily operate the switch device 12 when going out and returning home. Become. Further, if the collective opening / closing device 1 and the panel body 41 are unified as a whole, the appearance is improved. Here, “adjacent” means that the collective switchgear 1 and the distribution board 4 are arranged in the same space (for example, the entrance).

Specifically, the switch device 12 adopts the same mounting structure as the branch breaker 3 illustrated in FIG. 5 as the mounting structure to the mounting member 45, and is mounted to the case 43 of the panel body 41 so as to be removable from the case 43. May be. According to this configuration, the switch device 12 is attached to the panel body 41 of the distribution board 4 in the same manner as other internal units such as the branch breaker 3, so that the switch device 12 can be easily attached to the distribution board 4. In the case where the collective opening / closing device 1 includes the display unit 15, it is desirable that the display unit 15 is also fixed to the panel main body 41 using the attachment member 45, similarly to the switch device 12.

  Further, in the distribution board device 10, as in the present embodiment, the board body 41 has a cover 44 that covers the plurality of branch breakers 3, and the cover 44 has the switch device 12 of the collective switching device 1. It is desirable to form a window hole 46 that exposes. According to this configuration, since the user can operate the switch device 12 even when the door 441 is in a closed state, there is an advantage that time and labor when operating the switch device 12 can be saved. When the collective opening / closing device 1 includes the display unit 15, it is desirable that the cover 44 is also formed with a window hole (display window 47) that exposes the display unit 15 of the collective switching device 1. The switch device 12 and the display unit 15 may be provided at a position (around the door 441) of the inner cover 442 that is not covered by the door 441. In this case, the window hole is not provided in the inner cover 442 but the door 441. Is formed.

  By the way, the switch device 12 may be integrated with the contact device 11. In this case, the relay device 14 is omitted, and the contact device 11 in the switch device 12 is inserted between the target breaker and the target circuit. It will be. Thereby, the number of parts of the collective switching device 1 can be reduced.

  The collective opening / closing device 1 may be disposed adjacent to the distribution board 4, and is not limited to the configuration integrated with the distribution board 4 as described above, but is configured separately from the distribution board 4. May be. When the collective switching device 1 is configured separately from the distribution board 4, the switch device 12, the relay device (contact device 11) 14, and the display unit 15 are separated from the panel body 41 (not shown). And the casing is disposed adjacent to the panel main body 41.
