摘要

内蒙古鄂尔多斯石泥召变电站35kV线路接电感性负荷时

经常发生电容式电压互感器爆保险现象。本文详细分析了CVT的工作原理及等值电路

得出了由于甩负荷时产生过电压使中间电压互感器铁芯饱和与分压电容发生铁磁谐振

从而导致熔断器熔断的结论。比较了常用的几种消谐措施

提出用电灯泡代替普通电阻

既能起到防止铁磁谐振又能监视消谐回路是否开路的作用

并在现场得到验证。

Abstract

The fuse of 35 kV capacitor voltage transformer is usually burned out when reactive load are rejected in Shinizhao substation of Eerduosi

Neimenggu province.This paper has carefully analyzed the principle and equivalence circuit of CVT.When line load rejected

overvoltage is generated

the core of intermediate voltage transformer is saturated and ferromagnetic resonance occurs with voltage-dividing capacitor

and then causes the fuse fused.Several kinds of measures to eliminate ferromagnetic resonance have compared.It is suggested that replace ordinary resistance with bubble

which not only restrains ferromagnetic resonance

but also can keep watching on the status of eliminating resonance circuit.And it has got verification in practice.
