摘要

根据中国1 000 kV特高压交流试验示范工程的特点

在分析国外特高压工程用电压互感器的基础上

比较了柱式电容式电压互感器、电磁式电压互感器和电子式电压互感器的优缺点

并介绍了CVT的原理、1 000 kV CVT参数选择、结构要求等

对中国1 000 kV交流特高压工程用电压互感器进行了选型

得出为现场维修方便

选择叠装CVT较好。

Abstract

According to the characteristic of the China 1 000 kV AC UHV pilot project

this paper analyzes the features of voltage transformer used in the UHV projects both at home and abroad

and compares the disadvantages and advantages of column type capacitive voltage transformer（CVT）

electromagnetic voltage transformer and electronic voltage transformer.Hence the voltage transformer for the 1 000 kV AC UHV pilot project is selected.In addition

the CVT working mechanism

the parameters selection and the structure requirement of the 1 000 kV CVT are introduced.
