摘　　要：分析了低压断路器分断过程中电弧背后击穿和母排相间击穿两种典型击穿现象之间的关系,提出了把抑制背后击穿和母排相间击穿作为一个问题统一解决典型,并探讨了解决问题的途径和一些具体措施。Arc back-strike and strike between terminal were typical strike phenomena in low voltage circuit breakers,the relation between two strike phenomenas was analyzed and it was suggested restraining arc back-strike and strike between terminal could be concluded as one problem,some methods and measurements were introduced to restrain strike back commutation arc.

关 键 词：低压断路器 击穿 背后转移 电弧
