摘要

极母线金属氧化物避雷器是±800 k V特高压直流换流站的关键过电压保护设备之一

其技术研究和产品开发是实现特高压直流设备国产化的一个重要课题。笔者以中国哈密—郑州特高压直流工程为依托

深入研究了±800 k V特高压直流换流站极母线金属氧化物避雷器的关键技术

包括:1大直径直流金属氧化物电阻片技术;2复合外套技术;3多柱电阻片柱并联技术;4悬挂安装技术等。产品通过了全部的型式试验项目

成功地应用于±800 k V哈密—郑州特高压直流工程中

填补了国内特高压直流极母线避雷器领域的空白

提高了特高压直流设备的国产化率。

Abstract

Pole bus metal oxide surge arrester is one of the key overvoltage protection devices for ±800 k V UHVDC converter station. Its technology research and product development is an important task to realize the nationalization of UHVDC equipment. Based on Hami-Zhengzhou UHVDC project in China

the authors make the studies of the key technologies of pole bus metal oxide surge arrester for ±800 k V UHVDC converter station. It is included: 1 large diameter DC metal oxide varistor technology; 2 polymer housing technology; 3technology of multi-column varistors in parallel and 4suspension installation technology. With all the type tests done

the products are applied successfully in Zhengzhou converter station of ±800 k V UHVDC project. All of the type testing items are passed and the product is successfully applied in ±800 k V UHVDC Hami-Zhengzhou engineering

which is the first pole bus metal oxide surge arrester in China for UHVDC converter station.
