摘要

传递过电压试验是互感器检测试验中比较难以实现的试验

电容式电压互感器由于其主电容较大而使得其传递过电压试验难度很大。利用冲击试验电压发生器

通过对其试验回路的分析研究和计算

得到了满足标准要求的电容式电压互感器的A型传递过电压冲击波

并对电容式电压互感器的传递特性作了初步研究。

Abstract

Transfer overvoltage test is difficult to achieve in instrument transformers’ detection.Due to the large capacitance of capacitor voltage transformer（CVT）

test of transfer overvoltage is more difficult.By way of analysis

study and calculation of the test circuit of the impulse voltage generator

A-type transfer overvoltage impulse wave of CVT meeting the standard requirements has been obtained

and the transfer characteristic has also been preliminarily investigated in this paper.
