摘要

自愈式低压并联电力电容器普遍存在着早期失效损坏现象

其中使用不当也是主要原因。通过案例分析认为

耐过电流能力差、电容量容易衰减是自愈式电容器的弱点

将自愈式低压并联电力电容器直接应用于滤波器中存在一定的危害性

对于要求电容量稳定的滤波器来说

选用非自愈式电容器更为合适

如果要选择自愈式电容器

也应该是符合滤波要求设计的自愈式滤波电容器。

Abstract

Self-healing type low voltage shunt power capacitor generally exists such phenomena as early failure and damage and improper use is also the main reason.It is thought through case analysis that lower over current withstand ability and easy attenuation of capacitance are the weak point of the selfhealing type capacitor.There are certain dangers when it is used in the filter directly

to meet the stable capacitance requirement of the filter

choose non self-healing capacitor is more suitable to.The selfhealing capacitor

in case of selection

shall be the one complying with the filtering design requirement.
