消弧线圈接地系统两种异常状态的分析

Analyses of Two Unusual Cases in the Resonaut Grounding System

为了消除单相弧光接地过电压和电压互感器铁磁饱和过电压而装设消弧线圈。本文分析因消弧线圈安装调试不当而产生的耦合传递谐振过电压的原因,并提出了限制的措施。

In order to eliminate overvoltage caused by single phase arc-grounding faults and saturation of potential transformers, the arc suppression coils are used ,This paper gives a analyses of coupling transfer resonant overvoltage produced by inadequate ajustment of arc suppressions in the resonant grounding systen, Meanuhile, the restrictive measures to the ouervoltage in such systemsare introduced.
