开关传动轴、开关传动轴组件以及三工位隔离开关
摘要：
本发明涉及一种开关传动轴、开关传动轴组件以及三工位隔离开关。三工位隔离开关包括开关传动轴组件，开关传动轴组件包括传动轴和传动绝缘子，传动绝缘子上嵌设有与传动轴止转配合的轴套嵌件，相邻的传动轴与轴套嵌件之间设有弹性导体，传动轴上设有沿其轴向延伸的凹形区，弹性导体一端处于凹形区中，另一端从凹形区中伸出并与轴套嵌件顶压配合。本发明的三工位隔离开关的传动轴与轴套嵌件之间通过弹性导体导电连接，保证传动轴与轴套嵌件之间始终有效导电连接，形成导电通路，这样两者处于同一电位上，在使用过程中就不会发生放电，从而避免了绝缘击穿，有效提高了三工位隔离开关的安全性能。
摘要（英）：

The invention relates to a switch transmission shaft, a switch transmission shaft assembly and a three-station isolation switch. The three-station isolation switch includes a switch transmission shaft assembly including transmission shafts and transmission insulators, shaft sleeve inserts in scotching cooperation with the transmission shafts are inserted on the transmission insulators, elastic conductors are arranged between the adjacent transmission shafts and the shaft sleeve inserts, the transmission shafts are provided with recessed areas extending in the axial direction, one ends of the elastic conductors are arranged in the recessed areas, and the other ends extend out of the recessed areas and abut against the shaft sleeve inserts. The transmission shafts and the shaft sleeve inserts are in conductive connection through the elastic conductors, the transmission shafts and the shaft sleeve inserts are always in effective conductive connection to form conductive path, in this way, the transmission shafts and the shaft sleeve inserts are on the same potential, discharging can be prevented during the use, and insulation breaking through can be prevented, and the safety performance of the three-station isolation switch can be effectively improved.
