摘要： The present disclosure provides an arc-free DC circuit breaker that combines magnetic induction transfer and resistive current limiting. The circuit breaker comprises a main current circuit and a transfer current circuit. The transfer current circuit has a bridge structure; with a group of unidirectional components having a breaking function, bidirectional current breaking is implemented, such that compared with the prior art, usage of the turn-off devices may be reduced to half. By controlling action sequences of the trigger gap, high-speed switch, and power semiconductor, fast switching arc-free opening of the main current circuit is implemented; meanwhile, the breaking capability of the circuit breaker is significantly improved. By virtue of the current limiting module circuit inside the transfer current circuit, the present disclosure quickly limits short-circuit fault current, and then reduces the number of parallel groups of full-controlled devices of the breaking module circuit. Compared with the existing circuit breaker structures, usage of turn-off devices and cost of the circuit breaker may be significantly reduced.
