500kV紧凑型线路防雷特性研究

Analysis on Lightning Protection of 500 kV Compact Transmission Line

通过对典型地区近年来雷击跳闸以及雷电活动情况进行调查分析,针对500 k V紧凑型输电线路发生绕击跳闸与设想的差异情况,对其展开防雷特性研究,重点考察在各种因素的影响条件下,线路的绕击率变化情况,得出了相关结论,并提出了一些针对性的防护措施。

According to the investigation and analysis on lightning trip-out and lightning activities in typical area during these years, pointing on the difference of shielding failure of 500 kV Compact Transmission Line between facts and expectation, kinds of research on the lightning protection are put up. Focus on those inlfuence factors of shielding failure, a series of conclusions are drawn, some lightning protection methods are also proposed.
