摘　　要：为有效提高沿海架空输电线路的防风偏闪络性能,文章通过对大量架空输电线路风偏闪络案例的研究,结合风偏闪络原理分析了位于沿海地区的架空线路过线塔发生风偏闪络故障的原因,结合实例对一种实用过线塔的防风偏闪络改造方法,并对具体实施施和应用进行了阐述。In order to effectively improve the performance of coastal overhead transmission lines against wind flashover,the article analyzes the wind flashover of overhead transmission lines in coastal areas through the study of a large number of overhead transmission lines wind flashover cases and the principle of wind flashover.The cause of partial flashover failure,combined with an example,presents a practical method of retrofitting a pylon against wind and partial flashover,and expounds the specific implementation and application.
