摘要

550 k V GIS设备中配置的电磁式电压互感器（VT）在某些特殊运行工况下会产生铁磁谐振现象。笔者就其产生的原因进行了分析

认为GCB断口间的并联电容、GIS母线的对地电容以及VT的非线性电感所构成的串联LC回路是产生谐振的主要因素

同时提出3/2接线（或4/3接线）的串内T区是最危险的工况。借助EMTP解析手段可对铁磁谐振现象进行验证推断

采用追加可饱和电抗器的方法可对谐振现象进行有效抑制。

Abstract

The electromagnetic voltage transformer（VT） configured in 550 k V GIS can generate ferroresonance under some special operating conditions. Through analyzing the causes of ferroresonance

it is con-cluded that the series LC circuit constituted by shunt capacitance between GCB breaks

the bus to earth capacitance in GIS

and the nonlinear inductance of VT are the main factors to generate ferroresonance.The T-area of 3/2 connection or 4/3 connection is the most dangerous operating condition. Furthermore

through validating ferroresonance by using EMTP analytical method

it is concluded that additional saturable reactor can effectively restrain ferroresonance.
