摘要
随着电网电压等级的不断提高,雷击线路引起跳闸、停电事故日益增多,雷电成为了危害电力系统安全、稳定、经济运行的一个重要因素。基于此,重点分析了均匀无损导线的雷电波过程与多导线系统的雷电波过程,最后分析了输电线路的防雷保护,介绍了几种常用的防雷措施。
The tripping and power cut caused by thunder and lightning line are more and more along with continuous in- creasing voltage level of the electric network. The thunder and lightning has become an important factor that harms the e- lectric power system safety. Based on this reason,the paper laid special stress on analyzing uniform non -less line thun- der and lightning wave process and multiple - line system thunder and lighting wave process. Finally, analyzed thunder orotection of the transmission line and presented several common thunder prctection measures.
