摘要

±800 kV直流输电是目前世界上直流输电领域电压等级最高的输电方式。±800 kV特高压直流换流阀是特高压直流输电（UHVDC）中的关键设备

在投入电网使用之前必须要进行严格的型式试验。单阀交流耐压试验

是特高压直流换流阀绝缘型式试验中一个比较特殊的试验项目。笔者以国内自主试验的首例±800 kV换流阀绝缘型式试验为例

介绍了±800 kV换流阀相关电气结构

并对单阀交流试验的加压方法进行了研究。

Abstract

± 800 kV DC transmission is a current transmission approach of the world’s highest level in the area of the direct current transmission system.±800 kV HVDC thyristor valve is the key equipment in Ultra-High Voltage DC（UHVDC） transmission.It must be taken rigorously type test before put into operation.AC voltage test of single valve is a special test item in the valve dielectric tests.In this paper

taking the first domestic independent testing

± 800 kV thyristor valve dielectric test

as an example

introduces the associated electrical structure

and studies the test methods on single valve’s AC voltage test.
