水电及火电系统真空断路器操作过电压的保护

Protection of Switching Surge Voltage of Vacuum Breaker in Water and Thermal Power Station

在高压厂用电系统中保护真空断路器操作过电压有几种方式,本文提出在工程设计中采用何种保护方式的建议。

This paper firstly introduces several ways of the switching surge voltage protection for the vacuum breaker in water and thermal power stations,then gives proposals on how to choose the protection ways in the project design.
