电力电网真空开关过电压的产生及防护

Generation and Protection of Overvoltage of Vacuum Switch in Electric Power Network

真空开关操作过电压是人们普遍关心的问题，并在一定程度上影响着它的发展。介绍了真空开关过电压的类型及产生原因，提出了一些防止真空开关控制感性负载和容性负载操作过电压的措施。

Overvoltage of vacuum switch during operation is a generally interested issue,and has some effect on the development of vacuum switch.The categories and reasons of vacuum switch overvoltage are introduced,and the measures of preventing vacuum switch controlled induction loads,and capacitive loads from overvoltage are put forward.
