摘要

叙述了并联电容器极壳之间进行交流耐压试验时出现的噪声现象

针对这些异常噪声产生的原因进行了分析

并对并联电容器进行极壳间交流耐压试验的施加电压回路进行了说明;并从电容器的原材料质量和制作工艺控制方面提出了改进措施以避免这种噪声的产生;指出了只有减小并联电容器的局放才是消除这些异常噪声的关键。

Abstract

The noise issue occurred in AC withstand voltage test between terminal and carapace of shunt power capacitor is described

the reason for such abnormal noise is analyzed and the voltage applied circuit for AC withstand voltage test between terminal and carapace of shunt power capacitor is explained.Improvement measures are proposed from the aspects of raw material and manufacturing process so to avoid generation of such noise.It is pointed out that the key to eliminate such noise is to reduce partial discharge of shunt capacitor.
