摘要

针对以SF

气体为介质的同轴电容结构的电子式电压互感器

在不同SF

气体压力变化的情况下

对电子式电压互感器精度影响进行分析

得出气体压力变化对电子式电压互感器精度存在一定的影响

压力变化范围大时

甚至将不能满足精度要求。本文通过对2台电子式电压互感器的SF

气体压力变化进行精度试验

验证了分析结果

最后考虑到在要求电子式电压互感器SF

气体工作范围宽

互感器精度高的时候

提出需要进行补气或者补偿等措施来满足精度要求。

Abstract

In this paper

as for coaxial capacitive and electronic voltage transformer with SF

gas as dielectric medium

the influence on accuracy class of the electronic voltage transformer at different variation of SF

gas pressure is analyzed.It is concluded that variation of the SF

gas pressure has a definite influence on the accuracy of electronic voltage transformer and can even

in case of bigger pressure variation range

not meet accuracy requirement.The analysis result is verified through accuracy test of SF

gas pressure variation of two units of electronic voltage transformer and

in case of considering wide working range of SF

gas of electronic voltage transf

ormer and high accuracy of the instrument transformer

such measures as gas refilling and compensation are put forward to meet accuracy requirement.
