(A) If the circuit breaker is not cut off, the current flowing through the circuit breaker By detecting the occurrence of an accident, the accident section is detected by a change in the current value flowing through the division switch belonging to the accident distribution line at the time, based on the state of the switchgear and the transmission path stored in advance. In the section being used, the load curve of the breaker is used to calculate the back-fed flow, the load is moved to feed from other distribution lines, and the accident section is separated at the end. (b) In case that the breaker for banning is interrupted, wait for re-injection of the breaker for exclusive use of the van, turn on the switch sequentially from the power supply side, and read the current flowing in the input switch as the section current at the time of accident. The accident section is detected and separated by the change in the current value. After that, in the power failure section after the accident section, the back-flush calculation is performed using the load curve of the breaker, and the power is supplied from another wiring. (c) If the breaker for power distribution is cut off and the breaker for power distribution is re-inserted, the switchgear is sequentially inserted, and if the breaker is cut off again due to the input of the switchgear in the accident section, In the section on the power supply side of the accident section, the power is transmitted by multiple inputs of the circuit breaker, and in the section on the load side, backfeeding is performed from the reverse supply line. 이것을 특징으로 하는 배전 계통에 있어서의 사고구간을 검출분리하는 방식.A method of detecting and separating an accident section in a distribution system characterized by this. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
