摘要

本文论述了某500 kV变电站发生的一起35 kV电容器组故障的现象

分别从现场检查、设备返厂解体及试验等方面对故障原因进行综合分析

查找出故障原因为电容器组框架之间因异物搭接造成了相间短路、电容器损坏。针对本次故障暴露出的问题

提出了防止类似故障的改进措施

对电容器的安全运行有一定的参考价值。

Abstract

In this paper

one fault of 35 kV capacitor bank at certain 500 kV substation is described

the comprehensive analysis is made from such aspects as site inspection

disassembly at the factory and tests etc.The reason of the fault is found to be inter-phase short circuit and capacitor damage due to overlap of foreign matter between capacitor bank frames.As for the problem

improvement measure to prevent such similar fault is proposed

which has a definite reference value for safe operation of capacitor.
