Abstract

A household distribution box comprises a distribution box case; two service lines introduced from a transformer into the distribution box case of a consumer; three main lines installed in the distribution box case and provided with two lines and a second service line; two sub-lines installed in the distribution box case and formed by branching the second service line among the main lines into two lines; a first circuit breaker installed in the distribution box case; a second circuit breaker installed in the distribution box case; and a controller connected to the first circuit breaker.

Claims

1. A household distribution box comprising:

a distribution box case;

first and second service lines introduced from a transformer into the distribution box case of a consumer;

first, second and third main lines installed in the distribution box case, the first and second main lines being formed by branching the first service line into two lines, the third main line being connected to the second service line;

first and second sub-lines installed in the distribution box case and formed by branching the third main line into two lines;

a first circuit breaker installed in the distribution box case, connected to the first main line and the first sub-line, and configured to maintain or stop supply of regular power supplied from the transformer through the first main line and the first sub-line, the first circuit breaker including a first switch and a second switch, the first switch configured to interrupt the regular power supplied through the first main line and the first sub-line in response to a signal of a substation, the second switch configured to interrupt standby power supplied through the first main line and the first sub-line in response to a signal of a terminal;

a second circuit breaker installed in the distribution box case, connected to the second main line and the second sub-line, and configured to maintain or stop supply of the regular power supplied from the transformer through the second main line and the second sub-line; and

a controller connected to the first circuit breaker and configured to control an operation of the first circuit breaker through power line communication.

2. The household distribution box of claim 1, wherein the controller operates the first circuit breaker using the power line communication with a substation and interrupts the regular power.

3. The household distribution box of claim 1, wherein the controller operates the first circuit breaker using the power line communication with a terminal and interrupts the regular power.

4. The household distribution box of claim 3, wherein the controller performs the power line communication with the terminal including an application which allows the power line communication to be performed.

5. The household distribution box of claim 1, wherein the first circuit breaker is for forcible interruption and the second circuit breaker is for interruption of the regular power supplied by a regular power source.

6. A forcible power interruption system comprising:

a substation configured to supply regular power to a consumer and perform power line communication;

a transformer configured to receive the regular power supplied from the substation, transform a voltage of the regular power to a general working voltage, and supply the regular power having the general working voltage to the consumer; and

a household distribution box configured to receive the regular power supplied from the transformer and perform the power line communication with the substation,

wherein the household distribution box includes;

a distribution box case;

first and second service lines introduced from the transformer to the distribution box case of the consumer;

first, second and third main lines installed in the distribution box case, the first and second main lines being formed by branching the first service line into two lines, the third main line being connected to the second service line;

first and second sub-lines installed in the distribution box case and formed by branching the third main line into two lines;

a first circuit breaker installed in the distribution box case, connected to the first main line and the first sub-line, and configured to maintain or stop supply of the regular power supplied from the transformer through the first main line and the first sub-line, the first circuit breaker including a first switch and a second switch, the first switch configured to interrupt the regular power supplied through the first main line and the first sub-line in response to a signal of the substation, the second switch configured to interrupt standby power supplied through the first main line and the first sub-line in response to a signal of a terminal;

a second circuit breaker installed in the distribution box case, connected to the second main line and the second sub-line, and configured to maintain or stop supply of the regular power supplied from the transformer through the second main line and the second sub-line; and

a controller connected to the first circuit breaker and configured to control an operation of the first circuit breaker through the power line communication.

7. The forcible power interruption system of claim 6, wherein the controller operates the first circuit breaker using the power line communication with the substation and interrupts the regular power.

8. The forcible power interruption system of claim 6, wherein the controller is installed between the first main line and the first circuit breaker.
