摘　　要：对真空断路器弹簧操动机构的机械特性进行了计算,得到了弹簧机构在无故障情况下的正常分闸速度特性曲线,计算结果与实测曲线吻合较好;同时还计算了弹簧机构在主要故障点发生故障情况下的故障分闸速度特性曲线,计算结果可用于断路器机械特性的在线监测、故障诊断以及状态维修。The mechanical characteristics of spring operating mechanism of vacuum circuit breaker is calculated theoretically and the normal opening speed curve is obtained when spring mechanism is operated under normal condition The calculation results have good coincidence with the real testing results And at the same time, the fault opening speed curves are calculated assuming that some components of the spring operation mechanism are in fault The calculation results are valuable for the circuit breakers on line monitoring, fault diagnosis and condition maintenance
