摘要

针对40.5 kV真空断路器开断并联电抗器的工况

为了消除现有仿真模型的不足

笔者简单综述了真空断路器开断感性小电流的仿真研究的现状

得到其触头间介质动态绝缘强度曲线、高频电流熄灭判据和截流数据

并建立了断路器开断并联电抗器的三相仿真模型

同时考虑了三相间的耦合。应用ATP-EMTP软件进行了该型号真空断路器开断并联电抗器的三相仿真研究

并与现场试验结果进行了比对

仿真结果与试验结果大致相符。

Abstract

Aiming at the operating conditions of 40.5 kV vacuum circuit breaker switching off shunt reactors

and in order to eliminate deficiencies in the existing simulation model

a general review of simulating researches on vacuum circuit breakers switching off small reactive current is given.A three-phase model of 40.5 kV circuit breakers switching off shunt reactors is set up based on the experimental results of a type of 4.5 kV vacuum circuit breaker

including the dielectric strength characteristics

high-frequency current quenching criteria and chopping current.And the interphase coupling is considered in the model.A three-phase simulation is conducted for the transient process of the vacuum circuit breaker switching off shunt reactors via ATP-EMTP

and the simulation results coincide almost with experimental results.
