摘要

通过对某500 kV输电线路断路器取消合闸电阻的投切试验、断路器事故进行分析，并对此进行电磁暂态仿真计算，讨论了500 kV输电线路断路器取消合闸电阻的原则，与线路操作过电压幅值、线路两端高压并联电抗器配置情况的关系。研究结果表明，500 kV输电线路断路器合闸电阻配置时，需要考虑线路高压并联电抗器的配置情况，这将直接影响断路器断开的成功与否。

Abstract

The opening-closing test and circuit breaker fault of circuit breaker without closing resistors in 500 kV transmission lines are analyzed and simulated. The criterion of removing circuit breaker closing resistors is discussed. The relationship between the criterion of removing circuit breaker closing resistors and switching over-voltage magnitude， the HV shunt reactors installed in the two terminals of the line is described. It draws a conclusion that the necessary condition about the criterion of removing circuit breaker closing resistors in 500 kV transmission line should be the scheme of HV shunt reactors of the line.
