一起35kV电容器组爆炸故障的分析
摘要
本文论述了某500kV变电站发生的一起35kV电容器组爆燃故障的现象
分别从现场检查、设备返厂试验、现场过电压试验等方面对故障原因进行综合分析
认为故障原因为部分电容器存在缺陷并最终导致爆炸。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。
Abstract
In this paper
one explosion fault of 35kV capacitor bank at a 500kV substation is described
and the reasons for such explosion are analyzed comprehensively from such aspects as site inspection
testat the factory and overvoltage tests at site etc. Thinking the reason is the defect existence of partial capaci-tors
which eventually leading to the explosion. For the problem exposed in this fault
the improvementmeasures to prevent such fault are proposed.
