摘要

为了配合葛州坝换流站直流滤波器电容器的损坏事故分析

进行了电容器常温和高温状态

直流电压作用下的局部放电试验。在常温和高温状态下

分别用双臂式抗干扰回路

和微窗口电路

有效地抑制了外部干扰。测量结果表明

电容器在高温状态下的直流局部放电量较常温下没有显著增加。文中还对电容器直流局部放电测量时所应注意的问题进行了讨论。

Abstract

Ln order to help the analysis of the damage causes for the filter capacitors installed in GZB converter station

the tests of partial discharge under DC voltage for the capacitors were performed under normal and high temperature conditions using two—arm connection and microwindow circuit to suppress the interference. The results show that the DC partial discharges of the capacitors under normal temperature don’t have any apparent development under high temperature. The paper also discusses some problems about the DC partial discharge measurement for capacitors.
