In the embodiment, the switch 2 is a main breaker provided in the distribution board 100 . In the embodiment, load B1 is electrical equipment provided at facility 200 . In an embodiment, facility 200 is a single-family home. However, the facility 200 is not limited to a detached house, and may be, for example, each dwelling unit of an apartment complex, or non-residential buildings such as an office, a store, a factory, and a hospital.

The shutdown control system 1 includes a power failure detection unit 11 and a determination unit 121, as shown in FIG. The power failure detection unit 11 detects power failure of the power supply P1 (see FIG. 2). The determination unit 121 performs determination processing for determining whether or not to shut off the switch 2 when the power failure detection unit 11 detects a power failure of the power source P1. Then, the determination unit 121 determines to cut off the switch 2 when the specific condition is satisfied in the determination process. In the present disclosure, "satisfying a specific condition" means, for example, that the power failure time from the power failure of the power source P1 to the power recovery is longer than or equal to a predetermined time. The predetermined time is, for example, 24 hours, but it may be shorter than that. The breaking system 10 includes a breaking control system 1 and a switch 2, as shown in FIG.

In the shut-off control system 1 and the shut-off system 10 according to the embodiment, the switch 2 is shut off when a specific condition is satisfied because there is a high possibility of an electrical fire occurring in the facility 200 . Therefore, compared to the case where the switch 2 is not cut off even if the specific condition is satisfied, it is possible to reduce the occurrence of electrical fires when power is restored to the power source P1. In other words, according to the shutdown control system 1 and the shutdown system 10 according to the embodiment, it is possible to reduce the occurrence of electrical fires when power is restored after a power outage due to a disaster. A “disaster” as used in the present disclosure is a typhoon as an example, but may be an earthquake, heavy rain, heavy snow, flood, tsunami, landslide, or the like.

(2.2) Shutdown Control System Next, the shutoff control system 1 will be described with reference to FIG.

The shutdown control system 1 includes a power failure detection unit 11, a control unit 12, a power supply unit 13, and an auxiliary power supply unit 14, as shown in FIG. The shutdown control system 1 further includes a switch SW1 and a resistor R1.

The power failure detection unit 11 detects power failure of the power supply P1. Specifically, the power failure detection unit 11 detects the voltage on the primary side or the voltage on the secondary side of the switch 2, and detects the power failure of the power supply P1 when the voltage is no longer detected. Further, in the embodiment, the power failure detection unit 11 also detects the power recovery of the power supply P1 by detecting the voltage that was once undetected. However, when the power failure detection unit 11 detects the voltage on the secondary side of the switch 2, the voltage cannot be detected when the switch 2 is in the OFF state even if power is supplied from the power supply P1. 2 is in an off state, it is preferable that the voltage can be detected.

The control unit 12 has a computer system with a processor and memory. The computer system functions as the control unit 12 (determining unit 121, timer unit 122, and acquisition unit 123, which will be described later) by the processor executing appropriate programs. The program may be prerecorded in a memory, or may be provided by being recorded in a non-temporary recording medium such as a memory card or through an electric communication line such as the Internet.

The control unit 12 has a determination unit 121, a timer unit 122, and an acquisition unit 123, as shown in FIG.

The determination unit 121 is configured to determine whether or not the switch 2 should be shut off. Specifically, the determination unit 121 compares the power outage time measured by the clock unit 122 with a predetermined time, and determines that the switch 2 is to be shut off when the power failure time is equal to or longer than the predetermined time. In other words, the judgment part 121 judges that the switch 2 is cut off when the specific condition is satisfied. In other words, the determination unit 121 determines that the specific condition is satisfied when the power outage time measured by the timer 122 is longer than or equal to the predetermined time in the above determination process. In other words, "satisfying the specific condition" means that the power outage time measured by the timer 122 is longer than or equal to the predetermined time. The power failure time is the time from when the power failure detection unit 11 detects the power failure of the power source P1 to when it detects the power recovery. The predetermined time is, for example, 24 hours (one day). In other words, if the power supply P1 has been out of power for 24 hours or more, the determination unit 121 determines that the switch 2 should be shut off because there is a high possibility that an electrical fire will occur when the power supply P1 is restored.

Further, in the embodiment, the determination unit 121 is configured to determine whether or not to cut off the switch 2 based on the detection information from the detection device 6 . That is, the determination unit 121 according to the embodiment determines whether or not to cut off the switch 2 based on both the detection information from the detection device 6 and the power failure time of the power supply P1. The detection device 6 includes, for example, a water ingress sensor 61 and a vibration sensor 62 . The flood sensor 61 is installed, for example, under the floor of the facility 200 and detects whether or not the facility 200 is flooded. The vibration sensor 62 is installed, for example, on a wall surface of the facility 200 and detects vibration, inclination, and the like of the facility 200 . For example, in the case of a typhoon, there is a possibility that the facility 200 will be flooded due to heavy rain and that the facility 200 will shake due to a storm. "Abnormality" as used in the present disclosure includes disconnection of wiring, electric leakage in wiring or load B1, tracking, short-circuit accident, and the like. The number of each of the water ingress sensor 61 and the vibration sensor 62 may be one, or may be plural. The predetermined time is stored in the memory of the controller 12, for example.

When determining to cut off the switch 2, the determination unit 121 outputs to the switch SW1 a switching signal for switching the switch SW1 from OFF to ON.

The timer 122 is, for example, a timer. The clock unit 122 is configured to clock the power failure time. The timer 122 starts measuring the power failure time when the power failure detection part 11 detects a power failure of the power supply P1, and stops measuring the power failure time when the power failure detection part 11 detects the power recovery of the power supply P1. Here, in a situation where the clock unit 122 measures the power outage time, the power supply P1 is out of power and the power supply from the power supply unit 13 is stopped, so power is supplied from the auxiliary power supply unit 14. .

The acquisition unit 123 is configured to acquire detection information from the detection device 6 . For example, if the detecting device 6 is the flood sensor 61, the detection information is flood information indicating that the water level in the facility 200 is equal to or higher than a predetermined value. This is shake information indicating that the shake is greater than or equal to a predetermined value. The determination unit 121 determines whether or not to shut off the switch 2 based on the detection information acquired by the acquisition unit 123 .

The power supply unit 13 is, for example, an AC-DC converter that converts AC power from the power supply P1 into DC power. The power supply unit 13 outputs the generated DC power to the control unit 12 . That is, the power supply unit 13 generates control power for the control unit 12 .

The auxiliary power supply unit 14 is, for example, a battery. The auxiliary power supply unit 14 is charged while power is being supplied from the power supply P1, and supplies (discharges) power to the control unit 12 when the power supply P1 fails.

The switch SW1 is an a-contact (normally open contact) and is, for example, a semiconductor element such as a thyristor. A first end of the switch SW1 is electrically connected to the first voltage line L11 via the resistor R1. A second end of the switch SW1 is electrically connected to the neutral line L13. Resistor R1 limits the current flowing through switch SW1. The switch SW1 is switched from OFF to ON in accordance with the switching signal from the determination unit 121, thereby generating a pseudo-leakage state and breaking the switch 2. FIG. In other words, when determining that the switch 2 should be shut off, the determination unit 121 turns on the switch SW1 to generate a pseudo electric leakage state, thereby shutting off the switch 2 .

As shown in FIGS. 1 and 2, the interruption control system 1 according to the embodiment includes a first voltage line L11, a second voltage line L12, and a neutral line L13 that constitute an electric circuit L1. It is electrically connected to the neutral line L13.

(3) Operation Next, the operation of the shutdown control system 1 according to the embodiment will be described with reference to FIGS. 3 to 5. FIG.

(3.1) Operation example 1
First, an operation example 1 of the shutdown control system 1 will be described with reference to FIG.

The determination unit 121 of the control unit 12 determines whether or not the acquisition unit 123 has acquired the detection information from the detection device 6, that is, whether or not the first determination condition is satisfied (step ST101). Here, the acquisition unit 123 acquires detection information from the detection device 6 when at least one of the inundation sensor 61 and the vibration sensor 62 detects an abnormality in the facility 200 . Therefore, when neither the flood sensor 61 nor the vibration sensor 62 detects an abnormality in the facility 200, the detection device 6 outputs no detection information.

If the acquisition unit 123 has acquired the detection information (step ST101: Yes), the determination unit 121 determines whether the power supply P1 has failed based on the detection result of the power failure detection unit 11 (step ST102). When the power supply P1 is out of power (step ST102: Yes), the determination unit 121 causes the timer 122 to start measuring the power outage time (step ST103). After that, the determination unit 121 determines whether or not the power supply P1 has been restored based on the detection result of the power failure detection unit 11 (step ST104). If the power supply P1 has not been restored (step ST104: No), the determination unit 121 causes the timer unit 122 to continue measuring the power failure time (step ST103).

If the power source P1 has been restored (step ST104: Yes), the determination unit 121 causes the timer unit 122 to stop measuring the stop time, and compares the power failure time with the predetermined time (step ST105). If the power outage time is equal to or longer than the predetermined time (step ST105: Yes), the determination unit 121 determines to cut off the switch 2 (step ST106). At this time, the determination unit 121 outputs a switching signal for switching the switch SW1 from off to on to the switch SW1 in order to cut off the switch 2 . The switch SW1 is switched from off to on according to the switching signal. As a result, a pseudo leakage current flows through the closed circuit including the series circuit of the switch SW1 and the resistor R1, and the zero-phase current transformer 22 detects the pseudo leakage current, thereby breaking the switch 2. Here, when the switch 2 is shut off, it is preferable to provide notification means such as an LED, a buzzer, or the like, in order to notify the user (for example, a resident of the facility 200) that the switch 2 is shut off.

On the other hand, if the first determination condition is not satisfied (step ST101: No), if the power supply P1 has not failed (step ST102: No), or if the power failure time is shorter than the predetermined time (step ST105: No), does not block the switch 2.

By the way, when the switch 2 is cut off, there is a high possibility that an electric fire will occur when the switch 2 is turned on again. Therefore, for example, it is preferable for an electrician or the like to check the state of the wiring, the load B1, etc., and turn on the switch 2 again if there is no safety problem.

That is, in operation example 1, the determination unit 121 executes the determination process after the power supply P1 is restored, and when the determination unit 121 determines to shut off the switch 2 in the determination process, the switch 2 is shut off. do.

(3.2) Operation example 2
Next, an operation example 2 of the shutoff control system 1 will be described with reference to FIG.

The determination section 121 of the control section 12 determines whether or not the acquisition section 123 has acquired the detection information from the detection device 6, that is, whether or not the first determination condition is satisfied (step ST201). Here, the acquisition unit 123 acquires detection information from the detection device 6 when at least one of the inundation sensor 61 and the vibration sensor 62 detects an abnormality in the facility 200 . Therefore, when neither the flood sensor 61 nor the vibration sensor 62 detects an abnormality in the facility 200, the detection device 6 outputs no detection information.

If the acquisition unit 123 has acquired the detection information (step ST201: Yes), the determination unit 121 determines whether the power supply P1 has failed based on the detection result of the power failure detection unit 11 (step ST202). When the power source P1 is out of power (step ST202: Yes), the determination unit 121 outputs a switching signal to the switch SW1 to switch the switch SW1 from off to on. Then, for example, electric power from the auxiliary power supply unit 14 is used to cause a pseudo leakage current to flow through the series circuit of the switch SW1 and the resistor R1, thereby shutting off the switch 2 (step ST203). In operation example 2, the switch 2 is cut off when the power failure detection unit 11 detects a power failure of the power source P1.

After shutting off the switch 2, the determination unit 121 causes the timing unit 122 to start measuring the power failure time (step ST204). After that, the determination unit 121 determines whether or not the power source P1 has been restored based on the detection result of the power failure detection unit 11 (step ST205). If the power source P1 has not been restored (step ST205: No), the determination unit 121 causes the timer unit 122 to continue measuring the time of the power failure (step ST204).

When the power supply P1 has been restored (step ST205: Yes), the determination unit 121 stops counting the stop time by the clock unit 122, and compares the power failure time with the predetermined time (step ST206). If the power outage time is equal to or longer than the predetermined time (step ST206: Yes), the determination unit 121 keeps the switch 2 in the cut-off state. Also in the operation example 2, it is preferable to provide a notification means such as an LED, a buzzer, or the like, in order to notify the user (resident) that the switch 2 has been shut off.

On the other hand, when the power failure time is shorter than the predetermined time (step ST206: No), the determination unit 121 automatically restores the switch 2 in the cut-off state (step ST207). In this case, for example, it is preferable to provide a return circuit for returning the contact 21 of the switch 2 from OFF to ON by power supplied from the auxiliary power supply section 14 .

Furthermore, when the first determination condition is not satisfied (step ST201: No), or when the power supply P1 is not out of power (step ST202: No), the switch 2 is not cut off.

In the operation example 2 as well, when the switch 2 is cut off, if the power outage time is longer than the predetermined time, turning on the switch 2 again is highly likely to cause an electrical fire. Therefore, for example, it is preferable for an electrician or the like to check the state of the wiring, the load B1, etc., and turn on the switch 2 again if there is no safety problem.

That is, in the operation example 2, the switch 2 is cut off when the power failure detection unit 11 detects the power failure of the power source P1. The determination unit 121 executes the above determination process after the power supply P1 is restored.

(3.3) Operation example 3
Next, an operation example 3 of the shutoff control system 1 will be described with reference to FIG.

The determination section 121 of the control section 12 determines whether or not the acquisition section 123 has acquired the detection information from the detection device 6, that is, whether or not the first determination condition is satisfied (step ST301). Here, the acquisition unit 123 acquires detection information from the detection device 6 when at least one of the inundation sensor 61 and the vibration sensor 62 detects an abnormality in the facility 200 . Therefore, when neither the flood sensor 61 nor the vibration sensor 62 detects an abnormality in the facility 200, the detection device 6 outputs no detection information.

If the acquisition unit 123 has acquired the detection information (step ST301: Yes), the determination unit 121 determines whether the power supply P1 has failed based on the detection result of the power failure detection unit 11 (step ST302). When the power supply P1 is out of power (step ST302: Yes), the determination unit 121 causes the timer unit 122 to start measuring the time of the power failure (step ST303).

After that, the determination unit 121 compares the power outage time with the predetermined time, and determines that the switch 2 is shut off when the power outage time is equal to or longer than the predetermined time (step ST304: Yes) (step ST305). At this time, the determination unit 121 outputs a switching signal for switching the switch SW1 from off to on to the switch SW1 in order to cut off the switch 2 . The switch SW1 is switched from off to on according to the switching signal. As a result, a pseudo leakage current flows through the closed circuit including the series circuit of the switch SW1 and the resistor R1, and the zero-phase current transformer 22 detects the pseudo leakage current, thereby breaking the switch 2. Even in this case, the series circuit of the switch SW1 and the resistor R1 is controlled by the power from the power supply P1 if the power supply P1 has been restored, or by the power from the auxiliary power supply unit 14 if the power supply P1 has not been restored. A pseudo earth leakage current can flow in In addition, when the switch 2 is shut off, it is preferable to provide notification means such as an LED, a buzzer, or the like, in order to notify the user (resident) that the switch 2 is shut off.

On the other hand, if the first determination condition is not satisfied (step ST301: No), if the power supply P1 has not failed (step ST302: No), or if the power failure time is shorter than the predetermined time (step ST304: No), does not block the switch 2.

In the operation example 3 as well, when the switch 2 is shut off, there is a high possibility that an electrical fire will occur when the switch 2 is turned on again. Therefore, for example, it is preferable for an electrician or the like to check the state of the wiring, the load B1, etc., and turn on the switch 2 again if there is no safety problem.

That is, in the operation example 3, the determination unit 121 executes the determination process when the power failure detection unit 11 detects a power failure of the power supply P1. Switch off the switch 2.

(4) Effect In the shutoff control system and shutoff system 10 according to the embodiment, when the specific condition is satisfied, the determination unit 121 determines that the switch 2 is blocked. Therefore, compared to the case where the switch 2 is not cut off even if the specific condition is satisfied, it is possible to reduce the occurrence of electrical fires when power is restored to the power source P1. That is, according to the shutdown control system 1 and the shutdown system 10 according to the embodiment, it is possible to reduce the occurrence of electrical fires when power is restored from a power outage caused by a disaster.

(5) Modifications The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiments can be modified in various ways according to design and the like as long as the object of the present disclosure can be achieved. Also, functions similar to those of the shut-off control system 1 according to the above-described embodiment may be embodied by a control method of the shut-off control system 1, a computer program, or a non-temporary recording medium recording the computer program.

A control method of the breaking control system 1 according to one aspect is a control method of the breaking control system 1 capable of breaking the switch 2 provided in the electric line L1 connecting the power source P1 and the load B1. The control method of the shutdown control system 1 includes a power failure detection step (for example, step ST102) and a determination step (for example, step ST105). A power failure detection step is a step of detecting a power failure of the power supply P1. The judgment step is a step for judging whether or not to shut off the switch 2 when the power failure of the power source P1 is detected in the power failure detection step. In the determination step, it is determined that the switch 2 is to be shut off when a specific condition is satisfied. A program according to one aspect is a program for causing one or more processors to execute the control method of the shutdown control system 1 .

Modifications of the above-described embodiment are listed below. Modifications described below can be applied in combination as appropriate.

(5.1) Modification 1
In the above-described embodiment, the determination unit 121 determines whether or not to shut off the switch 2 based on the power failure time of the power source P1. You can judge whether Hereinafter, an interruption control system 1A according to Modification 1 will be described with reference to FIGS. 6 and 7. FIG. In the blocking control system 1A according to Modification 1, the same components as those of the blocking control system 1 according to the above-described embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.

A shutdown control system 1A according to Modification 1 includes, as shown in FIG. The shutdown control system 1A according to Modification 1 further includes a switch SW1 and a resistor R1. Furthermore, the control unit 12 has a determination unit 121 , a timer unit 122 and an acquisition unit 123 .

The communication unit 15 is, for example, a communication interface for communicating with a communication device provided at a facility of a general electric power company such as an electric power company. The communication unit 15 can be connected to the communication device via a network such as the Internet, for example. The communication unit 15 is configured to receive external information from the communication device. The “external information” referred to in the present disclosure is, for example, information from a general electric utility, such as power recovery information that notifies power recovery of the power supply P1, or shutdown of the switch 2 accompanying power recovery of the power supply P1. This is the requested information. In Modification 1, the external information is request information. Further, in Modification 1, the external information is pushed to the shutdown control system 1A. That is, the external information is notified from the general electric utility company regardless of whether or not there is a request from the shutdown control system 1A.

Next, an operation example of the cutoff control system 1A according to Modification 1 will be described with reference to FIG.

Judgment section 121 of control section 12 judges whether or not power supply P1 is out of power based on the detection result of power outage detection section 11 (step ST401). When the power source P1 is out of power (step ST401: Yes), the determination unit 121 determines whether or not there is external information (step ST402).

If there is external information, that is, request information (step ST402: Yes), the determination section 121 determines to shut off the switch 2 (step ST403). At this time, the determination unit 121 outputs a switching signal for switching the switch SW1 from off to on to the switch SW1 in order to cut off the switch 2 . The switch SW1 is switched from off to on according to the switching signal. As a result, a pseudo leakage current flows through the closed circuit including the series circuit of the switch SW1 and the resistor R1, and the zero-phase current transformer 22 detects the pseudo leakage current, thereby breaking the switch 2.

On the other hand, the judgment part 121 does not cut off the switch 2, when the power supply P1 is not cut off (step ST401: No), or when there is no external information (step ST402: No).

Also in Modification 1, when the switch 2 is shut off, turning on the switch 2 again is highly likely to cause an electrical fire. Therefore, for example, it is preferable for an electrician or the like to check the state of the wiring in the facility 200, the load B1, etc., and turn on the switch 2 again if there is no safety problem.

That is, in the shutoff control system 1 according to Modification 1, the determination unit 121 determines whether or not to shut off the switch 2 based on the external information in the above determination process.

In the shut-off control system 1 according to Modification 1 as well, the determination unit 121 shuts off the switch 2 when there is external information, since there is a high possibility that an electrical fire will occur in the facility 200 . Therefore, compared with the case where the switch 2 is not cut off even if there is external information, it is possible to reduce the occurrence of electrical fires when the power supply P1 is restored. That is, according to the shutdown control system 1 and the shutdown system 10 according to Modification 1, it is possible to reduce the occurrence of electrical fires when power is restored from a power outage caused by a disaster.

Although the push notification of the external information is given to the shutdown control system 1 in the modified example 1, the pull notification may be made in response to a request from the shutdown control system 1, for example.

In addition, the communication unit 15 is not limited to the Internet, for example, a mobile phone such as a 3G (third generation) line, an LTE (Long Term Evolution) line, a 4G (fourth generation) line, or a 5G (fifth generation) line. It may communicate with the communication device via a network, a satellite line, or a public wireless LAN (Local Area Network).

Furthermore, the control unit 12 has a determination unit 121 , a timer unit 122 and an acquisition unit 123 .

As shown in FIG. 8, the breaking control system 1B according to Modification 2 is electrically connected to the first voltage line L11 and the neutral line L13 via the contact 31 of the branch breaker 3 on the primary side of the switch 2. It is That is, in the interruption control system 1B according to Modification 2, power is supplied from the power source P1 while the branch breaker 3 is on.

A first end of the switch SW1 is electrically connected to a first voltage line L11 on the primary side of the switch 2 via the resistor R1 and one contact 31 of the branch breaker 3 . A second end of the switch SW1 is electrically connected to the neutral line L13 on the secondary side of the switch 2 . The switch SW1 is switched from OFF to ON in accordance with the switching signal from the determination unit 121, and the switch 2 can be cut off by artificially flowing leakage current through a closed circuit including the series circuit of the switch SW1 and the resistor R1. can.

The notification unit 16 has, for example, a speaker. The notification unit 16 is configured to notify the user (resident) that the power source P1 has been restored. When the power supply P1 is restored, the notification unit 16 outputs, for example, a voice message such as "The power supply P1 has been restored" from the speaker. Here, since the interruption control system 1B according to the modification 2 is connected to the primary side of the switch 2, even if the switch 2 is in an interrupted state, the notification unit 16 notifies when the power supply P1 is restored. It can be carried out.

The operation of the shutoff control system 1B is the same as that of the shutoff control system 1 according to the above-described embodiment, and the description is omitted here.

Also in the shutdown control system 1B according to the modified example 2, the determination unit 121 shuts off the switch 2 because there is a high possibility of an electrical fire occurring in the facility 200 when the specific condition is satisfied. . Therefore, compared to the case where the switch 2 is not cut off even if the specific condition is satisfied, it is possible to reduce the occurrence of electrical fires when power is restored to the power source P1. That is, according to the shutdown control system 1B and the shutdown system 10 according to Modification 2, it is possible to reduce the occurrence of electrical fires when power is restored from a power outage caused by a disaster.

In addition, when power is supplied from the primary side of the switch 2 as in the cutoff control system 1B according to Modification 2, the power supply P1 is restored regardless of the ON/OFF state of the switch 2. power can be supplied to the cutoff control system 1B.

Note that the notification unit 16 may have a buzzer instead of the speaker, and may notify that the power source P1 has been restored by the buzzer. Alternatively, the notification unit 16 may have a light emitting source such as an LED instead of a speaker, and may notify that the power source P1 has been restored by lighting or blinking the light emitting source. Furthermore, the notification unit 16 may have a speaker, a buzzer, and a light source, and these may be used together.
