摘　　要：混合式限流断路器作为传统断路器的理想替代品,一直受到科研人员的青睐。强迫换流作为混合式限流断路器的重要组成部分,换流方式直接决定了混合式限流断路器的协同控制策略及关键参数设计。基于“先分断再换流”和“先换流再分断”两种强迫换流方式过程分析及对比分析,研究了两种强迫换流方式的优缺点以及与高速电磁斥力开关协同控制的难易程度,为混合式限流断路器强迫换流方式的选择和参数设计提供了依据。Hybrid current-limiting breaker,which is an ideal substitute for the traditional circuit breaker,has been favored by researchers.Forced commutation is an important part of hybrid current limiting circuit breaker.The commutation mode directly determines the strategy of collaborative control and the key parameter design of hybrid current-limiting circuit breaker.Based on the process analysis and comparative analysis of two forced commutation modes,namely“break after commutation”and“break before commutation”,in this paper,we investigated the advantages and disadvantages of the two forced commutation modes and the difficulty of coordinated control with highspeed electromagnetic repulsion switch,which provides a basis for the selection of two forced commutation modes and the parameter design on hybrid current-limiting circuit breaker.
