摘要

采用并联电容器进行无功就地补偿是电力系统中优先采用的无功补偿方式

基于足够的绝缘距离及便于通风散热考虑

大部分产品安装于户外运行

其运行稳定性易受周围环境的诸多因素影响。本文针对一起35kV户外电容器组故障进行调查分析

通过现场设备检查、保护动作情况、电容器组内部设备试验情况进行故障定性、定位

分析故障发展过程

对故障产生的直接原因和间接原因分析总结

对防止发生类似故障提出了一些工作建议

以供读者参考。

Abstract

Using shunt capacitors for local reactive power compensation is the preferentially adopted reactive power compensation mode in power system.Based on a sufficient insulation distance and convenience in the ventilation and radiation

most of the products are installed and operated outdoor and their operation stability is easily affected by many factors of the surrounding environment.In this paper

the fault of an outdoor 35 kV capacitor bank is investigated and analyzed

the fault is located. Moreover

the fault development process is analyzed through the on-site inspection of the equipment

operation situation and testing of internal equipment in the capacitor bank.The direct and indirect causes for the faults are analyzed and summarized

and some suggestions on preventing such similar faults are proposed

for the reference to the readers.
