摘　　要：介绍了一种新型带有主、辅电路的真空负荷开关,它具有低截流、高转移电流.长寿命、高性能价格比的特点,主要用于三相环网或终端供电的市区配电站和工业设备中,利用这种负荷开关构成的组合电器尤其适用于对变压器的保护.This paper introduces a new vacuum load - breaking switch with main and auxiliary circuit, which is of lower current chopping level, higher transferring current. It can be mainly used for load control and short- circuit pro-tection in three - phase ring circuits or in the terminal distribution system and industrial devices at urban districts. In ad-dition , the combinations with such load - breaking switch are specially applicable to transformer protections.
