@ 1st and 512th backup cutoff at the branch point between 4 and 4! 11m't is provided. In this shiya breaker backup method, if a breaker 4o1ζ failure occurs, the breaker 4o does not have a failure detection function, so the breaker 4o will shut off in a failure state in the event of a ground fault on the load s side. There was a risk of a serious accident lζ on the system.

If there is a vacuum leak failure in one of the phases, when the current due to a one-line ground fault on the load side exceeds the breaking capacity of the faulty phase, an arc in the faulty phase will occur. This continues and develops into a serious accident.

The purpose is to ensure the protection of the power system by using a control method that operates.

Detection 11J 5o *51.5 to detect operational defects 1, such as a decrease in the degree of vacuum in each phase of a vacuum breaker or a disconnection in an operating electromagnet circuit, respectively. is provided, and the detection signal of each detector is a signal that suppresses the operation of the breaker to be detected. By providing this fault detection and control means,
For example, when a vacuum leakage failure occurs in the breaker 4o, the failure is detected and the disconnection operation is prohibited, and when an accident occurs on the load 3 side, the breaker 4o. In addition, if there is a failure in the cutoff 1i 4 *, then the cutoff @4
The cutoff operation lζ is performed by *. With this control method, it is possible to prevent a serious accident from occurring due to the breaking operation of a faulty breaker, and to take appropriate measures to deal with the accident.
