摘要

GIS用电磁式电压互感器（PT）进行现场感应耐压时

会出现加压二次线圈电流过大的问题。通过对PT结构的分析

认为杂散电容是导致电流过大的主要原因。从而提出了在PT非加压绕组接入感性负载

对测试系统进行补偿的方法。并对110～500 kV PT所需感性负载的大小进行了计算。该方法较好地解决了现场实际问题

对试验有一定的参考意义。

Abstract

During the on-site inductive voltage withstand test of Potential Transformer（PT）used in Gas Insulated Station（GIS）

there is a problem with the over current of the used second winding of the PT.According to the analysis of the construction of PT

it is the distributional capacitances that cause this over current.Thereby

an improved method for the inductive voltage withstand test of PT was presented in this paper.The method resolves the problem of the over current

by adding the induction load to the other second windings.Meanwhile the value of the induction load was also calculated for the PT of different rated voltage from 110～500 kV.This method resolves the practical problem and is useful to the on-site testing.
