摘要

介绍了并联电容器使用不当引起的5种故障案例:并联电容器投入不当引起的供电线路事故、并联电容器的工作环境温度过高引起的温控设备频繁跳闸故障、代换的并联电容器与原电容器电压规格不相符引起的系统功率因数过低故障、电容器配套接触器不合格引起的过热故障、电容器安装不规范引起的电容器法兰渗油故障。分析了这些故障产生的原因

介绍了故障处理的方法和步骤

以及避免发生同类故障的防患措施。

Abstract

In this paper

five cases of shunt capacitor fault caused by improper use are introduced

which leads power supply wire faults

such as follows

improper switching of shunt capacitor

frequent tripping of temperature control equipment because of excessive operating temperature of the shunt capacitor

extreme low system power factor due to insistency between the replaced capacitor voltage and original capacitor’s voltage

overheat due to unqualified contactor for the capacitor and oil leakage of capacitor flange due to non-standard installation of capacitor. The reasons of such faults are analyzed

the treatment method and procedure as well as prevention measure to avoid the same fault are introduced for reference.
