摘要

雷击是影响±500 k V直流架空输电线路运行的重要因素

±500 k V直流线路避雷器的挂网试运行成功

为直流线路防雷改造提供了有效技术手段

但大规模的工程应用仍是空白。笔者结合±500 k V江城线直流线路避雷器安装项目

研究了±500 k V直流线路避雷器选型、选点原则

给出了不同塔型下直流线路避雷器的安装方案

并提出直线塔宜采用悬挂式安装方案

耐张塔宜采用地面支柱式安装方案。运行数据表明

笔者提出的±500 k V直流线路避雷器选型、选点原则防雷改造效果明显

安装方案达到线路安全运行要求

对±500 k V直流线路避雷器的推广应用和在运直流线路防雷改造工作具有重要的实践和借鉴意义。

Abstract

Lightning is a key factor for the safe and reliable operation of ±500 k V high voltage direct current（HVDC）transmission lines. The DC arresters

which have been successfully applied in the ±500 k V HVDC transmission lines provide an effective method to protect against lightning. Based on a practical project of JiangCheng line

a ±500 k V HVDC transmission line of South China

both the procedure of selection and the principle of installation sites for DC arresters have been discussed in detail. It shows that the suspension DC arresters are applicable for the self-supporting towers whereas the supporting DC arresters are applicable for the strain towers.The operational data verified the proposed scenario. This work not only presents useful references for the extended application of ±500 k V DC arresters

but also is significant for the reform of lightning protection measures of current operating DC transmission lines.
