摘要: A switching controller for circuit breaker in which a switching control arithmetic operation unit performs arithmetic operations to determine for each circuit breaker a synchronous delay count value which is sent to each switching command control unit of the corresponding circuit breaker, which upon receiving a switching command signal from a superordinate device, counts the synchronous delay count value D, to turn on a semiconductor switch of the switching command output unit after counting completes. The switching command signal (circuit breaker drive current) is output after the synchronous switching control to the circuit breaker drive coil of the circuit breaker. The switching controller can implement cost saving and space saving, even if switching of a circuit breaker in a lower branch system, such as a power distribution system, is controlled.

摘要: The MPU for switching control arithmetic operation 210 in the switching control arithmetic operation unit 200 performs arithmetic operations to determine a predetermined delay time (synchronous delay count value D) for each circuit breaker 1100. The synchronous delay count value is sent to each switching command control unit 400 of the corresponding circuit breaker. The hardware counter 20 of the switching command output control unit 450, for the switching command signal received from the superordinate device 2000, counts the synchronous delay count value D, which is the delay time. When the semiconductor switch of the switching command output unit 10 turns ON after counting completes, the switching command signal (circuit breaker drive current) after the synchronous switching control is output to the circuit breaker drive coil 1110 of the circuit breaker 1100. A switching controller for circuit breaker and a switching control system for circuit breaker are provided, which can implement cost saving and space saving, even if switching of a circuit breaker in a lower branch system, such as a power distribution system, is controlled.
