摘要

针对河北南网500 kV变电站并联电容器组发热问题频发的情况

对河北南网并联电容器组近2年的发热问题进行统计分析。认为导致并联电容器组发热问题频发的主要原因是接头接触面处理工艺存在问题。通过对发热红外图片及发热接触面的分析

指出了接触面处理存在的误区

并提出了接触面处理的正确工艺以及一种全新的接头连接方式

在检修及消缺应用过程中取得了良好的效果。

Abstract

As for the frequent accidents of shunt capacitor bank heating in a 500 kV substation at southern grid in Hebei Province

the statistics on heating of shunt capacitor bank in recent 2 years is made. It is considered that the main reason leading frequent heating of shunt capacitor bank is in the treatment processing technology of the joint contacting surface. Through analysis of heating infrared images and the heated contacting surfaces

the misunderstanding existing in the treatment of contacting surface is pointed out

the correct treatment process and a kind of new connection mode are proposed. Good results are achieved in the maintenance and defect elimination.
