Description

  The present invention relates to a distribution board that distributes power supplied from a power supply line on a primary side to supply power to a plurality of areas. In particular, it has a plurality of breakers that electrically connect the primary power supply line drawn from outside and the indoor wiring drawn into each area to supply power to a plurality of indoor areas. The present invention relates to an indoor distribution board provided with a cutting means for cutting a typical connection.

  Conventionally, a distribution board (hereinafter referred to as an indoor distribution board) is used to supply electric power supplied from the primary side to a plurality of indoor areas.

  Such an indoor distribution board includes a plurality of breakers that electrically connect a primary power supply line drawn from outside and an indoor wiring drawn into each area to supply power to a plurality of indoor areas. ing.

  Each breaker has a cutting means for cutting the electrical connection between the primary side and the secondary side. In an emergency, etc., the electrical connection to the secondary side is cut off by the cutting means. Can be stopped.

  More specifically, the cutting means includes a switching mechanism (hereinafter referred to as “switching mechanism”) that can be switched between a connection state in which the primary side and the secondary side are electrically connected and a disconnection state in which the electrical connection is disconnected. A first switching mechanism). The first switching mechanism includes a lever for external operation, a contact that electrically connects the primary side and the secondary side, and a connection mechanism (for example, a link mechanism) that operatively connects the lever. By operating the lever, the connection state is switched between a connection state in which the contacts are opened and closed and electrically connected and a connection state in which the connection is disconnected. A general breaker includes an operating body (for example, a bimetal or an electromagnet) that operates a first switching mechanism (connection mechanism) when power consumption exceeds a predetermined level due to electric leakage, excessive use of electricity, etc. At times, the connection is automatically disconnected to prevent the occurrence of a fire.

  In the breaker configured as described above, since the connection mechanism operatively connects the contact point and the lever as described above, when the operating body operates the connection mechanism, the lever is also interlocked and operated by operating the lever. It is possible to return from the disconnected state to the connected state.

  Among the breakers that electrically connect the primary side and the secondary side in this way, there is a so-called earth leakage breaker configured to be in a disconnected state when an earth leakage occurs. In addition to the first switching mechanism, the disconnecting means for the earth leakage breaker further includes a switching mechanism (hereinafter referred to as a second switching mechanism) that switches from a connected state to a disconnected state at the time of electric leakage. The second switching mechanism is interlocked with an operating body such as an electromagnet that instantly operates the connection mechanism of the first switching mechanism, the connection mechanism of the first switching mechanism, etc. when the potential difference between the primary side and the secondary side approaches zero. It is equipped with an earth leakage display button to notify the occurrence of an earth leakage, and it is possible to prevent the occurrence of a fire accident associated with the earth leakage.

  In this earth leakage breaker, since the second switching mechanism is operatively provided in the first switching mechanism (connection mechanism), the lever is also interlocked when the connection mechanism is actuated by electric leakage, and the lever is operated to operate the lever. It is possible to return from the state to the connected state. Some earth leakage breakers may be restored by operating the lever while pushing the earth leakage display button.

  By the way, the stop of power supply to each indoor area is the stop of power supply from the primary side (power supply line) (power failure), the leakage on the secondary side of the indoor distribution board, the electricity in the area This is due to interruption of energization at the breaker due to excessive use of the battery, malfunction of the breaker, etc., but it is difficult to accurately grasp the cause of the stop of the power supply. In other words, the user can only determine that the power supply has been stopped at the position of the lever of the breaker in the indoor distribution board, and know whether it is due to a power failure, leakage, or excessive use of electricity. It is difficult to perform an appropriate restoration work that matches the cause. In particular, users who are poor in electrical knowledge do not know what measures should be taken and are confused by the return work.

  On the other hand, there has been proposed a power monitoring recorder that detects load current, leakage current, and line voltage (energized state) and analyzes the detection result to identify the cause of power failure. Merely identifies the cause of the power failure (see, for example, Patent Document 1).

For this reason, even if the cause of the power failure is specified, the user cannot know an appropriate coping method for the cause, and there is no substitute for being confused by the return operation.
Japanese Patent Laid-Open No. 5-264295

  Therefore, in view of such a situation, the present invention accurately grasps the cause when the power supply is stopped, and can notify the user of an appropriate response according to the cause. It is an issue to provide.

  The indoor distribution board according to the present invention includes a plurality of breakers that electrically connect the primary side and the secondary side, and each breaker cuts to disconnect the electrical connection between the primary side and the secondary side. A distribution board for indoor use, comprising: a first detection means for detecting a state of a cutting means in each breaker; a second detection means for detecting a primary-side energization state for each breaker; and a state of the cutting means Storage means for storing a plurality of guidance information corresponding to a plurality of combination patterns of the first and second energization states, and a combination pattern of detection results of the first detection means and the second detection means from among the plurality of guidance information It is characterized by comprising information extracting means for extracting guidance information corresponding to, and notifying means for notifying the content of the extracted guidance information to the outside. Here, the “guidance information” is information related to the explanation of the power supply stop to the user, and includes the cause of the power supply stop to the secondary side, the return procedure for the power supply stop, and the like. It is a waste.

  The indoor distribution panel having the above-described configuration is such that the notification information is extracted by the notification means corresponding to the combination pattern of the detection results of the first detection means and the second detection means. Based on the contents of the means, the current situation can be grasped accurately and quickly, and the power supply can be smoothly returned from the stoppage.

  Specifically, the breaker cutting means changes in form corresponding to the energized state (for example, a contact configured to be able to electrically connect the primary side and the secondary side and to disconnect the connection). Whether the disconnection is due to the breaker cutting means when the electrical connection is cut off by detecting the state of the cutting means by the first detection means. I can understand. And the energization state of the primary side rather than a breaker can be grasped | ascertained by detecting the energization state of the primary side of a breaker with a 2nd detection means.

  Therefore, a plurality of guidance information corresponding to a plurality of combination patterns (presumed trouble occurrence patterns) of the state of the cutting means and the energized state on the primary side is stored in advance in the storage means, and the information extraction means By extracting the guidance information corresponding to the combination pattern of the detection results of the first detection means and the second detection means from the guidance information, it is possible to extract appropriate guidance information that matches the current situation. In particular, since both the state of the cutting means and the energized state on the primary side are used as criteria for identifying the cause of the power supply stoppage, it is more reliable to identify the cause of the trouble than when judging only by the energized state. Of course, the reliability of extracting guidance information is high. Thereby, by notifying the content of the extracted guidance information by the notification means, the user can accurately and quickly grasp the current state of the trouble, and can smoothly perform the return work for the stop of the power supply. .

  As one aspect of the present invention, the breaker of each breaker can be switched from the outside to a connected state in which the primary side and the secondary side are electrically connected and a disconnected state in which the electrical connection is disconnected. It is preferable that one switching mechanism is provided, and each first detection unit includes a first switching mechanism detection unit that detects the state of the first switching mechanism. Generally, a breaker includes a first switching mechanism that can be switched from the outside to a connected state and a disconnected state in order to restore a connection that has been disconnected in an emergency. The first switching mechanism includes, for example, a lever operated by a user and a connection mechanism (for example, a link mechanism) that operatively connects the lever and the contact so as to open and close the contact. Are different in posture and mode between the connected state and the disconnected state. Therefore, by detecting the state of the first switching mechanism with the first switching mechanism detection means, it is possible to reliably grasp whether or not the breaker cutting means is used when the electrical connection is cut.

  In this case, one breaker of the plurality of breakers is a leakage breaker further provided with a second switching mechanism that switches the disconnecting means from the connected state to the disconnected state when the leakage occurs, and the other breaker is connected to the secondary side. The first detecting means corresponding to the earth leakage breaker further comprises second switching mechanism detecting means for detecting the state of the second switching mechanism, and the storage means is in the state of the first switching mechanism, the state of the second switching mechanism. And a plurality of guidance information corresponding to the combination with the energized state on the primary side of the breaker is stored, and the information extracting means includes a first switching mechanism detecting means, a second switching mechanism detecting means, and a plurality of guidance information, and You may be comprised so that the guidance information corresponding to the combination pattern of the detection result of a 2nd detection means may be extracted. In this way, even if an earth leakage breaker is adopted as one of the circuit breakers, the status of each earth leakage breaker and other breakers can be ascertained, and power outages caused by outdoor (primary side) causes In addition, it is possible to more accurately grasp both overuse of electricity on the secondary side corresponding to each breaker and electric leakage, and appropriate guidance information can be extracted from a plurality of guidance information.

  The notification means preferably includes at least one of a monitor that displays the content of the guidance information as at least one of characters and symbols, and a sound output device that emits the content of the guidance information as sound. . By doing in this way, the user can grasp | ascertain exactly the cause of the stop of electric power supply, and the method of return.

  In addition, the notification means includes a procedure notification means for notifying the order of the breakers to be restored based on the guidance information corresponding to the state when the plurality of breaker cutting means are disconnected from the electrical connection. May be. In this way, the user can surely grasp the return procedure, and it is possible to prevent a situation in which the return work is performed again due to omission.

  As described above, according to the indoor distribution board according to the present invention, it is possible to accurately grasp the cause when the power supply is stopped, and to inform the user of an appropriate response according to the cause. An excellent effect of being able to do so can be achieved.

  Hereinafter, an indoor distribution board according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  The indoor distribution board according to this embodiment is attached to an indoor wall surface or the like. As shown in FIGS. 1 and 2, the primary side and the secondary side are electrically connected, and the electrical connection is made. The plurality of breakers 1a, 1b... Provided with the cutting means 10 for cutting the first breaker 1a, 1b... The first detection means 2 for detecting the state of the cutting means 10 of each breaker 1a, 1b. Second detection means 3 for detecting the energization state on the side, storage means 4 for preliminarily storing a plurality of guidance information corresponding to a plurality of combination patterns of the state of the cutting means 10 and the energization state on the primary side, and a plurality of Information extraction means 5 for extracting guidance information corresponding to a combination of detection results of the first detection means 2 and the second detection means 3 from the guidance information, and notification means 6 for notifying the extracted guidance information to the outside When, When power supply from the next side is stopped, and a rechargeable power supply 7 in order to supply at least a storage unit 4, information extracting means 5, and a power notification means 6.

  The cutting means 10 of each breaker 1a, 1b ... is the 1st switching which can be switched from the outside in the connection state in which a primary side and a secondary side are electrically connected, and the disconnection state in which an electrical connection is cut | disconnected A mechanism 100 (see FIG. 3A) is provided. In addition, the breaker 1a among the plurality of breakers 1a, 1b,... Has a second switching mechanism 150 (FIG. 3 (B) in FIG. )) Is provided. The earth leakage breaker 1a is electrically connected to the secondary side through other cables on the secondary side. That is, the other breakers 1b are electrically connected to the primary side (power supply line drawn from the outside) via the leakage breaker 1a. In the following description, for the sake of convenience, the breakers 1b other than the leakage breaker 1a are referred to as general breakers, and when both the leakage breaker 1a and the general breakers 1b are targeted, they are collectively referred to simply as breakers.

  Each of the breakers 1a, 1b,... Employed in the indoor distribution board according to the present embodiment is a general one. However, generally speaking, the general breakers 1b are connected to the primary side (wiring from the leakage breaker 1a). , A contact point (not shown) for electrically connecting the secondary side (indoor wiring (not shown) from an area set indoors), and a cutting means 10 that opens and closes the contact point to switch between power supply and shut-off. (First switching mechanism 100) and a piezoelectric element (not shown) such as a bimetal as an operating body for opening a contact point and shutting off power supply when an overcurrent flows.

  The cutting means 10 (first switching mechanism 100) of the general breaker 1b, as shown in FIG. 3 (a), is a lever 101 for the user to operate from the outside, and the operation of the lever 101 and the opening and closing of the contacts. It is composed of a connection mechanism 102 that operatively connects the lever 101 and the contact point so as to be interlocked.

  The connection mechanism 102 employs a link mechanism, a cam mechanism, or a combination thereof. The connection mechanism 102 according to the present embodiment employs a link mechanism, and the piezoelectric element is also operatively connected. As a result, the piezoelectric element is activated (for example, deformed) as an overcurrent flows due to excessive use of electricity or the like, whereby the link mechanism 102 is activated, the contact is opened, and the position of the lever 101 is changed. Yes. Then, by changing (moving) the position of the lever 101 while the contact is open, the contact can be closed to return to a state where power can be supplied (energized).

  In the earth leakage breaker 1a, the cutting means 10 further includes the second switching mechanism 150 in addition to the first switching mechanism 100 as described above. Although there are various types of the second switching mechanism 150, the second switching mechanism 150 according to this embodiment has a current that flows suddenly due to the occurrence of electric leakage or the like, as shown in FIG. In other words, when the potential difference between the primary side and the secondary side approaches 0 or becomes 0, a magnetic force generator 151 as an operating body that instantaneously generates a strong magnetic force is provided so as to be tiltable. And a movable iron piece 152 operatively connected to the connection mechanism 102 of the first switching mechanism 100. In the second switching mechanism 150, the movable iron piece 152 is instantaneously operated by the strong magnetic force generated by the magnetic force generator 151 when a current suddenly flows, and the connection mechanism 102 of the first switching mechanism 100 is accordingly moved. Operates to open contacts.

  Furthermore, the earth leakage breaker 1a according to the present embodiment protrudes to the outside in conjunction with the operation of the movable iron piece 152 at the time of earth leakage and informs the user that the earth leakage has occurred (see FIG. 1). It has. The earth leakage display button 153 is operatively connected to the movable iron piece 152 or the connection mechanism 102, interlocks with the operation of the movable iron piece 152 and the like at the time of electric leakage, and protrudes to the outside (indicating that there is an electric leakage). In this state, the operation of the connection mechanism 102 is hindered, and the contact is not easily closed. That is, the earth leakage breaker 1a cannot be restored by operating the lever 101 of the first switching mechanism 100 in a state where the earth leakage display button 153 indicates that earth leakage has occurred. The electric leakage display button 153 can be returned by operating the first switching mechanism 100 (changing the position of the lever 101) while pushing the user so as to change from the protruding state to the retracted state.

  In addition, the connection mechanism 102 of the earth leakage breaker 1a according to the present embodiment is configured such that the lever 101 is in a neutral position when the contact is opened by the operation of the second switching mechanism 150. For closing, the lever 101 is once moved to the contact opening position (OFF position), and then the lever 101 is moved (returned) to the contact closing position (ON position).

  The first detection means 2 is provided for each of the breakers 1 a, 1 b... And includes a first switching mechanism detection means 20 that detects the state of the first switching mechanism 100. In addition to the first switching mechanism detection means 20, the first detection means 2 corresponding to the earth leakage breaker 1a further includes a second switching mechanism detection means 25 that detects the operating state of the second switching mechanism 150.

  As shown in FIG. 4A, a limit switch is employed for the first switching mechanism detection means 20 according to the present embodiment. The limit switch 20 includes a switch arm 200 that is rotatably provided, and a switch contact (illustrated) that switches from an OFF state to an ON state (or from an ON state to an OFF state) when the switch arm 200 rotates a predetermined angle. Not). The switch arm 200 is provided on the track of the first switching mechanism 100 (the pin 102a of the link mechanism 102 connected to the lever 101), and the pin 102a passing through a predetermined position functions as a striker and exceeds a predetermined angle. The switch contacts and switches the ON / OFF state of the switch contact. Note that the earth leakage breaker 1a according to the present embodiment is configured such that the lever 101 is neutral when the second switching mechanism 150 is actuated. For this reason, the first switching mechanism detection means 20 for the earth leakage breaker 1a. Is composed of a limit switch that detects that the lever 101 is in the OFF position and a limit switch that detects that the lever 101 is in the neutral position (not shown). The limit switch 20 (switch arm 200) of the earth leakage breaker 1a is provided at a position where a part of the first switching mechanism 100 functions as a striker.

  As shown in FIG. 4B, a limit switch is also adopted in the second switching mechanism detecting means 25 according to this embodiment. In the limit switch 25, the switch arm 210 is provided in the operating region of the second switching mechanism 150 (for example, on the track of the movable iron piece 152), and the movable iron piece 152 that passes through a predetermined position functions as a striker. The switch contacts are turned on and off by a predetermined angle or more.

  Returning to FIG. 2, both the first switching mechanism detection means 20 and the second switching mechanism detection means 25 are connected to a bus connected to an arithmetic processing unit (CPU 5) described later, and the switch contact is in the ON state (or OFF state). ) Is input as a signal to the CPU 5 via the bus B. That is, whether or not the lever 101 of the breakers 1a, 1b... Is in the OFF position (contact opening position) or the ON position (contact closing position) depending on whether or not a signal is input from the first switching mechanism detection means 20. The CPU 5 recognizes the presence of a signal from the second switching mechanism detection means 25 so that the CPU 5 can recognize that the second switching mechanism 150 has opened the contact due to electric leakage.

  The second detection means 3 employs a voltmeter, and each voltmeter 3 is connected to the bus B. Thereby, the energization state (for example, the presence or absence of voltage, the voltage value) on the primary side corresponding to each breaker 1a, 1b... Is input as a signal, and the CPU 5 recognizes whether it is energized or disconnected. It can be done.

  The storage means 4 is composed of a RAM, and is connected to the CPU 5 via the bus B. The storage means 4 includes software for the CPU 5 to perform a series of processing (for example, determination processing), the state of the first switching mechanism 100, the state of the second switching mechanism 150, and the primary side of the breakers 1a, 1b. And a plurality of guidance information corresponding to each combination pattern are stored. In the guidance information, character information having predetermined contents to be displayed on a monitor 60 described later, symbol information, and voice information emitted from a voice output device 61 described later are set.

  Guidance information varies depending on the corresponding combination pattern, but information related to the cause of power supply stoppage (for example, the cause of power supply stoppage and the procedure for returning it) or information indicating that the power supply has returned to normal is set. For example, when all the breakers 1a, 1b... Are in the ON state (lever 101 is in the ON position) and there is no voltage on the primary side of the breakers 1a, 1b. , And the condition that the lever 101 of the breakers 1a, 1b... Is in the OFF position without displaying the fact that the earth leakage display button 153 of the earth leakage breaker 1a is earth leakage. The information is stored in the RAM 4 in association with the guidance information “raise to ON position”. There are a plurality of other combinations of the combination of the state of the cutting means 10 and the energized state and guidance information associated therewith, but the explanation here is omitted, and for other examples the operation of the indoor distribution board And will be described later.

  In the present embodiment, a plurality of determination processes are performed to accurately grasp the cause of the stop of power supply, and accordingly, the plurality of guidance information includes the first detection unit 2 and the second detection unit. In addition to the combination pattern of the three detection results, it is also associated with the step position (address) of the determination process. Thereby, even if the combination pattern of the detection result of the 1st detection means 2 and the 2nd detection means 3 becomes the same state in a different process step in performing several judgment processing, it adapts to the step of the judgment processing. Guidance information can be extracted.

  The information extraction means 5 is composed of an arithmetic element (CPU), and performs a series of arithmetic processing (judgment processing, extraction processing, etc.) based on various information and signals input via the bus B. It is like that.

  The notification means 6 includes a monitor 60 that displays the content of the guidance information as at least one of characters and symbols, and a voice output device 61 that emits the content of the guidance information as a voice. In addition, the notification means 6 according to the present embodiment is configured such that when the contacts of the plurality of breakers 1a, 1b,... Are open (electrical connection is cut off) or the lever 101 is in the OFF position. A procedure notifying means 62 for notifying the order of the breakers 1a, 1b,.

  The monitor 60 is a thin display such as a dot display or a liquid crystal display. The monitor 60 is connected to the CPU 5 via the bus B, and displays guidance information stored in the storage unit 4 based on the processing result of the CPU 5. When the content of the guidance information cannot be displayed on one screen or when moving to the next step, the display content can be switched by operating the input means (NEXT button) 65 (see FIG. 1) provided separately. It has become.

  The audio output device 61 includes a sound source board (not shown), a speaker 600 (see FIG. 1), and the like. The voice output device 61 is connected to the CPU 5 via the bus B, and emits the content of the guidance information stored in the storage means 4 as voice based on the processing result of the CPU 5. In other words, the audio output device 61 emits audio of the content corresponding to the guidance information displayed on the monitor 60 from the speaker 600.

  The procedure notifying means 62 comprises a light emitting element (LED) and is provided corresponding to each of the breakers 1a, 1b. The procedure notification means 62 according to the present embodiment is composed of an LED 62a for indicating a return procedure and an LED 62b for indicating that a trouble has occurred, and a set of these two is provided for each breaker. (See FIG. 1). The procedure notification means 62 (LEDs 62a and 62b) is connected to the CPU 5 via the bus B. Then, the procedure notification means 62 returns based on the content of the guidance information and the arrangement (address information) of the breakers 1a, 1b,... Each breaker 1a, 1b... Is turned on. That is, the LED 62b indicating that a trouble has occurred continues to be lit corresponding to the corresponding breakers 1a and 1b, and the LED 62a for indicating the return procedure is lit corresponding to the breakers 1a and 1b. It disappears after the return operation.

  The CPU 5 and RAM 4 are provided on the same substrate, and the monitor 60, audio output device 61, LED 62, limit switch 20, voltmeter, etc. are electrically connected to the bus B line formed on the substrate. Connected.

  The rechargeable power source 7 includes a charging device (not shown) connected to a primary power supply line, and a battery (not shown) charged by the charging device. Even in the case of interruption (in the case of a power failure), the CPU 5 or the like can be reliably operated by supplying power from the battery, and appropriate guidance can be provided by the notification means 6. The rechargeable power source 7 (charging device) according to the present embodiment can charge the battery in a normal state and supply power to the substrate to always operate the CPU 5 and the like. .

  The indoor distribution board according to the present embodiment has the above configuration. Next, the operation of the indoor distribution board will be described. When power is normally supplied, each breaker 1a, Since the state of the cutting means 10 (the position of the laver 101) 1b and the energization state (voltage etc.) on the primary side are appropriate, the normal state pattern stored in the storage means 4 and the first detection means 2 Since the combination pattern of the detection results of the second detection means 3 matches, the notification means 6 does not notify at all, or the contents corresponding to the standard state, for example, as shown in FIG. “Guidance is displayed in case of emergency” is displayed.

  On the other hand, when the power supply is stopped, the combination pattern of the detection results of the first detection means 2 and the second detection means 3 does not match the pattern in the normal state. To be judged.

  Specifically, as shown in FIG. 5, whether all the breakers 1a, 1b... Are supplied with power from the primary side based on the detection results of the first switching mechanism detection means 20 and the second detection means 3 (ON (S10). When the CPU 5 determines that the levers 101 of all the breakers 1a, 1b... Are in the ON position but no signal is input from the second detection means 3 (the detection result is 0 V) (YES in S10), the power Guidance information D corresponding to this condition (a combination pattern of detection results, a processing step address (S10 in this case)) is assumed by the CPU 5 as a result of power supply being stopped due to a problem on the supply line side (outdoor) (power failure). The content of the extracted guidance information D is extracted by the notification means 6, for example, “Contact the nearest power company because there is a cause of power failure outside” (S 90).

  When the CPU 5 determines that the lever 101 of any one of the breakers 1a, 1b... Is in the OFF position (NO in S10), the second switching mechanism detection means 25 detects the state of the second switching mechanism 150 (indirectly). The display state of the leakage display button 153 is automatically determined), and it is determined whether there is a leakage on the secondary side based on the detection result (S20).

  If it is determined that there is no electric leakage on the secondary side (the electric leakage display button 153 does not indicate electric leakage) (NO in S20), the guidance information E corresponding to this condition is extracted by the CPU 5, and the guidance information E For example, the notification means 6 notifies that the lever in the OFF position is raised to the ON position (S100). At this time, if there are two or more breakers 1a, 1b... With the lever 101 in the OFF position, the procedure notifying means 62 (LED 62a) notifies the return procedure corresponding to the condition.

  Then, the CPU 5 stands by until the user operates the lever 101. When the signal from the first switching mechanism detecting means 20 is switched, the CPU 5 recognizes that the user has operated the lever 101, and the first detecting means 2 and Based on the detection result of the second detection means 3, it is determined whether or not the power supply has been restored normally (whether the power supply has been turned on) (S 120). When the lever 101 is in the ON position and the primary side is energized, when it is determined that the lever has returned to normal (YES in S120), the guidance information I corresponding to the condition is extracted by the CPU 5, and the guidance information I The content, for example, “normally restored” is notified by the notification means 6 (S160).

  On the other hand, based on the detection results of the first detection means 2 and the second detection means 3, the CPU 5 is in a normal state because the lever 101 is in the OFF position or no signal is input from the second detection means 3. When it is determined that the power is not supplied (NO in S120), the guidance information G corresponding to the condition is extracted by the CPU 5, and the content of the guidance information G, for example, “Are you using too much electricity? The notification means 6 notifies that the lever of the earth leakage breaker is set to the ON position and the lever of the general breaker is set to the ON position one by one (S130).

  Then, the CPU 5 stands by until the user operates the lever 101. When the signal from the first switching mechanism detecting means 20 is switched, the CPU 5 recognizes that the user has operated, and the first detecting means 2 and the second detecting means 2 Based on the detection result of the detection means 3, it is determined whether or not the power supply has been restored normally (whether the power supply has been turned on) (S140). As a result, when the lever 101 is in the ON position and the primary side is energized, when it is determined that the lever has returned to normal (YES in S140), the guidance information I corresponding to the condition is extracted by the CPU 5, and the guidance information I The notification means 6 is notified of the contents of, for example, “returned to normal” (S160).

  On the other hand, if the CPU 5 determines that the lever 101 is in the OFF position or that the current is not normally supplied because there is no signal input from the second detection means 3 (NO in S140), this condition is met. The guidance information H is extracted by the CPU 5 and the content of the guidance information H is notified by the notification means 6, for example, “Because it is impossible to return by personal work, contact the nearest power company”. (S150).

  If the CPU 5 determines in S20 that the leakage indication button 153 indicates a leakage (leakage on the secondary side) (YES in S20), the signal from the first switching mechanism detection means 20 of the leakage breaker 1a. Whether or not the lever 101 of the earth leakage breaker 1a is in the neutral position is determined based on the presence or absence of the input (S30). When the CPU 5 determines that the lever 101 of the leakage breaker 1a is in the neutral position (YES in S30), the guidance information F corresponding to the condition is extracted by the CPU 5, and the content of the guidance information F, for example, “leakage display” The notification means 6 notifies that the leakage breaker lever is moved from the OFF position to the ON position while pressing the button (S110).

  Then, the CPU 5 stands by until the user operates the lever 101. When the signal from the first switching mechanism detecting means 20 is switched, the CPU 5 recognizes that the user has operated, and the first detecting means 2 and the second detecting means 2 Based on the detection result of the detection means 3, it is determined whether or not the power supply has been restored normally (whether the power supply has been turned on) (S 50).

  On the other hand, if the CPU 5 determines in S30 that the lever 101 of the earth leakage breaker 1a is not in the neutral position (NO in S30), the guidance information A corresponding to the condition is extracted by the CPU 5, and the content of the guidance information A, for example, The notification means 6 notifies that the lever of the earth leakage breaker is moved to the ON position while pressing the earth leakage state display button (S40).

  Then, the CPU 5 stands by until the user operates the lever 101. When the signal from the first switching mechanism detection means 20 is switched, the CPU 5 recognizes that the user has operated, and the first detection means 2 and the second detection means 2 Based on the detection result of the detection means 3, it is determined whether or not the power supply has been restored normally (whether the power supply has been turned on) (S 50).

  Then, if the CPU 5 determines that the leakage is not normal in S50 and the lever 101 is in the ON position and the primary side is energized because the leakage is not indicated in S50 (YES in S50), it corresponds to that state. The guidance information I is extracted by the CPU 5, and the content of the guidance information I, for example, “return to normal” is notified by the notification means 6 (S170).

  On the other hand, the CPU 5 determines that the electric leakage is not normally supplied because the electric leakage display button 153 indicates electric leakage, or the lever 101 of the breakers 1a, 1b... Is in the OFF position or the primary side is not energized. In this case (NO in S50), the guidance information B corresponding to the condition is extracted by the CPU 5, and the content of the guidance information B, for example, “There is a possibility of electric leakage”, “all levers 101 are in the OFF position, The notification means 6 notifies that the lever 101 of the earth leakage breaker 1a is set to the ON position and then the levers 101 of the other breakers 1b... Are set to the ON position one by one (S60).

  Then, the CPU 5 stands by until the user operates the lever 101, and when there is an input of a signal from the first switching mechanism detecting means 20, the CPU 5 recognizes that the user has operated, and the first detecting means 2 and the first detecting means 2 Based on the detection result of the second detection means 3, it is determined whether or not the power supply has been restored normally (whether the power supply has been turned on) (S70).

  Then, when the CPU 5 determines that the leakage has not returned to the normal state because the leakage display button 153 does not indicate leakage and the lever 101 is in the ON position and the primary side is in the energized state (YES in S70), the guidance corresponding to the condition The information J is extracted by the CPU 5, and the content of the guidance information J, for example, “returned to normal” is notified by the notification means 6 (S170). On the other hand, the electric leakage display button 153 indicates electric leakage, or the lever 101 of the breakers 1a, 1b... Is in the OFF position, or no signal is input from the second detection means 3, so that the electric current is not normally supplied. (NO in S70), the guidance information C corresponding to the condition is extracted by the CPU 5, and the content of the guidance information C, for example, “the personal work is in a state where it is impossible to return, the nearest Is notified by the notification means 6 (S80).

  As described above, the indoor distribution board according to this embodiment notifies the guidance information extracted corresponding to the combination of the detection results of the first detection means 2 and the second detection means 3 by the notification means 6. Therefore, it is possible to inform the user of the cause of the stop of the power supply and the appropriate response according to the cause. Thereby, the user can take an appropriate response without being confused even in an emergency such as a stoppage of power supply. In particular, since both the state of the cutting means 10 and the energized state on the primary side of each breaker 1a, 1b,.. In addition to the specific reliability of the cause of the trouble, the guidance information can be extracted with high reliability.

  Further, since the first switching mechanism detection means 20 detects the state of the first switching mechanism 100, the ON / OFF state of the breakers 1a, 1b,. In particular, since the first detection means 2 corresponding to the earth leakage breaker 1a includes the second switching mechanism detection means 25 for detecting the operating state of the second switching mechanism 150, one of the plurality of breakers 1a, 1b,. Even if an earth leakage breaker is used, the state of each of the earth leakage breaker 1a and the general breaker 1b can be grasped, and the power failure caused by the cause of the outdoors (primary side), the two corresponding to the breakers 1a, 1b,. It is possible to accurately grasp both overuse and electricity leakage on the secondary side, and appropriate guidance information can be extracted from a plurality of guidance information.

  And since the monitor 60 and the audio | voice output apparatus 61 were employ | adopted for the said notification means 6, the user can grasp | ascertain exactly the cause of the stop of electric power supply, and the method of return. Further, since the procedure notifying unit 62 is provided in the notifying unit 6, it is possible to clearly notify the user of the return, and it is possible to suppress the situation where the return operation is performed again.

  Note that the indoor distribution board of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.

  In the said embodiment, although the earth-leakage breaker 1a was provided, it is not limited to this, The general breaker 1b ... may be provided electrically in parallel. Even in this way, the cause and countermeasure for stopping the power supply based on the indoor distribution board can be notified as guidance based on the detection results of the first detection means 2 and the second detection means 3. However, in view of operability and safety, it is needless to say that the leakage breaker 1a is preferably provided in the same manner as in the above embodiment.

  In the above embodiment, the limit switch is employed for the first detection means 2 (the first switching mechanism detection means 20 and the second switching mechanism detection means 25). However, the present invention is not limited to this, and for example, the first switching mechanism. You may employ | adopt the proximity switch etc. which respond according to operation | movement of 100 grade | etc.,. That is, the first detection unit 2 may be appropriately changed according to the configuration of the first switching mechanism 100 or the like as long as a detection result corresponding to the operation of the first switching mechanism 100 or the like can be obtained.

  Moreover, although the voltmeter was employ | adopted as the 2nd detection means 3 which detects the energization state of the primary side of breakers 1a, 1b ..., an ammeter, a wattmeter, etc. may be sufficient. That is, the second detection means 3 only needs to be able to detect the presence or absence of power supply on the primary side of the breakers 1a, 1b.

  Further, in the above embodiment, the procedure notification means 62 indicating the procedure for returning when the plurality of breakers 1a, 1b... Are in the OFF state is provided, but the present invention is not limited to this, and the procedure notification means. 62 may be provided as necessary.
