The earth leakage breaker 110 includes a current detector 111 , an earth leakage detector 112 and a connection breaker 113 .

The current detector 111 compares the input power and the output current passing through the load and converts the difference between the current values into a voltage value.

The earth leakage detector 112 compares the voltage value converted by the current detector 111 with a preset reference voltage value, and if the result of the comparison is greater than the preset reference voltage value, it is determined as an earth leakage.

When receiving an earth leakage signal from the earth leakage detector 112, the connection breaker 113 cuts off the electrical connection between the power supply and the load.

The earth leakage circuit breaker 110 detects an earth leakage occurring in each household, and when an earth leakage is detected, controls the earth leakage detection of the corresponding household so that the earth leakage is blocked. The integrated earth leakage breaker 180 detects an earth leakage occurring between the earth leakage breaker 110 and the integrated earth leakage breaker 180 for each generation in the wiring structure, and controls the earth leakage detection of the corresponding generation so that the earth leakage is blocked when an earth leakage is detected. .

In the power system of the present invention, wires distributed from a transformer are connected to the integrated earth leakage breaker 180 of an apartment house, and the power line 20 output from the integrated earth leakage breaker 180 is transmitted to each household 10a, 10b, and 10c. It is branched and input to the earth leakage breaker 110 installed in each household (10a, 10b, 10c), and the power line 20 output from the earth leakage breaker 110 is individually used as an electronic device required in the household (10a, 10b, 10c). is entered

In this case, an earth leakage signal is generated and transmitted to the control module 182.

The first, second, and third power detectors 181a, 181b, and 181c determine the generation of leakage current by detecting a change in current flowing through a resistor (not shown) connected to the power line.

Determines whether or not the expected time is continued by

When the earth leakage integration server 170 determines that the received electricity usage lasts for an expected time longer than a predetermined reference numerical value, it is determined as a risk of earth leakage and generates a earth leakage warning signal, and the electricity usage management server 160 connected to the corresponding household send to For example, when the electricity consumption is 500 and the reference numerical value is 400, if the expected time is set to 12 hours, if the electricity consumption 500 lasts for 12 hours or longer, it can be determined as a risk of electric leakage.

In addition, when the electricity consumption 500 does not exceed 12 hours or more, but lasts for about 10 hours and is detected as less than 12 hours later, the earth leakage integrated server 170 may determine the warning step, which is the pre-earth leakage risk step.
