摘　　要：在电力输送方面,防雷保护是需要重点关注的问题,尤其是在高海拔区域,由于海拔高、地形复杂、自然环境恶劣,且雷击风险较高,若线路防雷保护设计不当,会严重影响电力的正常输送。论文结合西藏地区500 kV输电线路建设项目,简要分析影响线路耐雷水平的因素,根据项目实际情况提出线路防雷保护设计的基本思路,并重点研究高海拔地区500 kV输电线路防雷保护措施。In terms of power transmission,lightning protection has always been a key concern,especially in high-altitude areas.Because of the high altitude,complex terrain,harsh natural environment and high risk of lightning strike,improper design of lightning protection for transmission lines will seriously affect normal power transmission.Combining with the construction project of 500 kV transmission line in Tibet,this paper briefly analyzes the factors that affect the lightning withstand level of the line,puts forward the basic ideas of lightning protection design of the line according to the actual situation of the project,and focuses on the lightning protection measures of 500 kV transmission line at high altitude.
