摘要

在气体绝缘变电站（gas insulated substation

GIS）中

断路器（circuit breaker

CB）过多的开关动作会引发绝缘故障。为了保障GIS的安全运行

有效地检测GIS中CB的绝缘故障

文中特提出一种新型监测方式。在建立了一个合成实验平台后

采取实验手段

以GIS内的CB为具体研究对象

测量了其开断操作所激发的电场脉冲

并总结出同一CB健康状态下因开关动作而激发的电场脉冲的典型波形。实验结果表明

通过分析实验测得的电场脉冲的波形特征

可以诊断GIS内CB的绝缘故障。

Abstract

In a gas-insulated substation（GIS）

excessive switching operations of a circuit breaker（CB） could result in insulation fault. In order to detect the insulation fault of a CB

a novel monitoring method was proposed in this study. Taking a CB in the GIS as the research object

a synthetic test platform was established to measure the transient electric field pulses generated by the opening operations of the CB.Further

typical waveforms of the electric field pulses excited by switching operation of the same CB in healthy state were obtained. Experimental results show that CB insulation fault can be detected by analyzing waveform feature of the electric field pulses.
