±500kV超高压直流输电线路雷击成因分析及防雷措施探讨

摘要

超高压直流输电线路为我国城市居民生活、工业生产用电等提供了保障，但是我国一直是遭受雷击灾害较为严重的国家之一，每年都会因雷击造成超高压直流输电线路的故障，输电线路的故障给人们的生活用电造成诸多不便，也使得我国的经济遭受巨大损失。文章对±500kV超高压直流输电线路雷击的成因进行了分析，并提出了超高压直流输电线路防雷的措施，为防雷提供了理论依据。%Ultra high voltage direct current transmission line provides the security for urban residents’living and industrial production in China,but our country has always been one of the countries suffering from serious lightning disasters,there are breakdowns of ultra high voltage direct current transmission line caused by lightning strike every year,the breakdowns of the transmission line cause inconvenience to people’s life,also makes our country’s economy suffered huge losses.The articles analyzes on lightning causes for + 500kV ultra high voltage direct current transmission line,and puts forward the measures of lightning protection of ultra high voltage direct current transmission line,provides a theoretical basis for lightning protection.
