摘　　要：本文从真空断路器的动作特性出发 ,讨论了真空断路器各种机构的特点以及与真空断路器动作特性的匹配情况 ,提出了一种真空断路器用新型的永磁机构 ,并从原理上论述了该机构具有可靠性高、零部件少、免维护等优点 ,同时 。Starting from the operational characteristic of vacuum circuit breaker, this paper discusses the features of various actuators for vacuum circuit breaker and their matching with the operational characteristic requirement of vacuum circuit breaker. A new type of permanent magnet actuator for vacuum circuit breaker is advanced wihch is demonstrated in principle to be higher reliable, less of parts and maintenance free. Meanwhile, several typical permanent magnet actuators are also introduced in this paper.
