摘要

结合现场故障调查和±500 kV江城线防雷特性

分析±500 kV江城线雷击故障特征。结果表明

线路设计档距过大及设计地线保护角过大、山区边坡地形效应是±500 kV江城线雷击故障的主要原因。针对直流输电线路的防雷设计和改造

提出了降低架空地线保护角、加装线路避雷器的防雷保护措施。

Abstract

According to fault investigation in field

the characteristics of lighting stroke fault of ±500 kV Jiangcheng transmission line is analyzed in this paper.The results show that the oversize design span and shielding angle and side slope effect are the primary cause of lightning trip-out for ±500 kV Jiangcheng line.The lighting protection countermeasures of reducing shielding angle and installing lighting arrester are put forward according to design and reform of lighting protection for DC transmission lines.
