Improvement of Switching-off and Tripping Part of the Spring Operating Device of Breaker Maintenance & Test Department of Fuyang Power Supply Company

目前变电站在装运行的高压开关柜,配用弹簧操动机构的真空断路器数量很多,对于早期设计和生产的C★、CT10型弹簧操动机构,普遍存在着分、合闸拒动问题,文中就解决这些实际问题介绍了改进方法,改进效果良好。

At present,there are many high-voltage switch cabinets equipped with vacuum circuit breaker operated by spring device in operation.
