摘要

随着±500 k V直流输电工程在中国电网上的可靠运行

直流输电的节能性、可靠性、稳定性得到验证;随着多项±800 k V特高压直流输电工程的顺利建成

中国在特高压直流输电线路的建设和工程运行中积累了丰富的经验。直流输电发展趋势向着超高电压、大电流（3 000

500 A）方向发展

超高电压、大电流的直流输电换流阀的制造主要依靠国外技术。为了研制超高电压、大电流的直流输电换流阀

就必须研究超高电压、大电流的直流输电换流阀的结构、技术参数

借鉴先进技术

取长补短

研制拥有自主知识产权的新型超高电压、大电流的直流输电换流阀

满足市场需要。研究±800 k V换流阀组件内电位分布的特性

为换流阀设计提供可靠、准确的设计依据;研究测量电位分布的的方法及测试技术

为进一步研究换流阀的电位分布积累基础数据。

Abstract

With reliable operation of domestic ±500 k V HVDC power transmission project

energy saving

reliability and stability of DC power transmission has been proved.As the project ±800 k V UHVDC power transmission projects successfully completed

the rich experiences of project construction and operation have been accumulated.DC power transmission is developing in a high voltage

high current（3 000

500 A）way.In order to extra high voltage and high current thyristor valve

structure and technical data must be studied to meet market requirement.The study is on potential distribution characteristic in thyristor module and on m

easuring method and measuring technology for potential distribution

providing reliable and accurate design basis for thyristor valve design.
