永磁操动机构真空断路器的工作原理及应用前景

摘要

By comparing the function of several operation structure used on vacuum circuit breaker, the characteristics and advantages of permanent magnet operation mechanism is highlighted. The structure of permanent magnet operation mechanism, operation priciple and the working priciple of electric control system of vacuum circuit breaker are analysed indetail and the important role of the application of permanent magnet operation mechanism on vacuum circuit breaker in the development of its free maintenance.%通过对真空断路器上采用过的几种操动机构性能对比，突出了永磁操动机构的特点和技术先进性。详析了永磁操动机构的结构、动作原理及真空断路器电气控制系统的工作原理，论证了永磁操动机构在真空断路器上的应用将对真空断路器向免维护方向发展起到非常重要的作用。
