摘　　要：在12 kV高速真空断路器中,一般不增加合闸缓冲装置,直动式操动机构往往会造成较大程度合闸弹跳,降低使用寿命。在优化设计的基础上,研制了一种双稳态永磁机构侧动式12 kV高速真空断路器。该真空断路器合闸时间在15 ms以内,分闸时间在10 ms以内,合闸弹跳时间短,分闸反弹幅值小,达到了预期的目的。In 12 kV high-speed vacuum circuit breakers,the switching-on buffer devices are generally not added,and the direct-acting operating mechanism often causes large switching-on bounce and reduces the service life.Based on optimized design,a new type of side-acting 12 kV high-speed vacuum circuit breaker with bistable permanent magnet mechanism is developed.By employing this kind of vacuum circuit breaker,the switching-on time of the vacuum circuit breaker is within 15 ms and the breaking time is within 10 ms.The switching-on bounce time gets shorter and the breaking rebound amplitude gets smaller.Thus,the predicted purpose is achieved.
