| Abstract: | Characteristics and causes of the operating over voltage were analyzed. Through lumped parameter equivalent circuit of no-load closing circuit, its over voltage was calculated. ATP-EMTP simulation software was used to complete 500 kV transmission line＇s simulation due to different operating over voltages, getting the characteristics of no-load closing over voltage on vacuum circuit breaker , which provides a reference for the over voltage suppression measures. |
