摘要
35 kV输电线路已成为雷害的重灾区。输电线路应用避雷针防雷符合传统防雷理论,但对35 kV架空输电线路而言有其局限性。根据雷电活动对35 kV线路的危害进行分析,结合一处实际运行的避雷针,初步探讨了避雷针在35 kV架空输电线路上的防雷应用利弊及相关注意事项。
35 kV transmission line has become a severely afflicted area due to lightning hazard. Using lightning rod on transmission line for protection against hghtning accords with the traditional theory of protection against lightning, but there are limitations on 35 kV overhead transmission line. The harms to 35kV transmission line caused by lightning activity are analyzed, and the advantages and disadvantages of lightning rod used on 35kV overhead transmission line for protection against lightning are discussed as well as matters needing attention.
