摘　　要：输电线路在电力系统中承担着供电的作用,由于其分布相对较广且长期暴露在外界环境中,所以容易影响供电线路运行的安全。基于此,分析现阶段电力系统输电线路防雷存在的不足,提出了雷电接闪器、差异化防雷技术、侧向避雷针等技术,可以加强今后电力系统输电线路的防雷保护。同时,对电力系统输电线路防雷保护期间需要注意的问题进行探讨,以减少雷击事故的发生,确保电力系统的安全运行。Transmission lines play the role of power supply in the power system.Due to their relatively wide distribution and long-time exposure to the external environment,they they can easily affect the safety of power supply line operation.Based on this,the shortcomings of lightning protection of transmission lines in current power systems are analyzed,technologies such as lightning arrester,differentiated lightning protection technology and lateral lightning rod are put forward,which can strengthen the lightning protection of transmission lines in power system in the future.At the same time,some problems that should be paid attention to during the lightning protection of transmission lines in power system are discussed to reduce the possibility of lightning accidents and ensure the safe operation of power system.
