| The lighting failure to220kV transmission line in Hangzhou area occurs frequently in recent years, which brings a lot of risks to the safe and stable operation of the grid. This article analyses the lighting trip reason about Hangzhou220kV overhead transmission line, the characteristics and problems about the lighting trip lines are found. Through the research on the principle of lightning discharge, the lightning protection measures for the transformation of the actual effect to carry on the analysis, combined with relevant theories, presents lightning protection measures on220kV Fuyun4Q361ine and Yangyun4Q351ine, and achieved good results in practice. Finally, combined with the lines of the actual operation situation, the integrated lightning protection measures on220kV transmission line of Hangzhou area are presented. This paper can provide reference to the units engaged in the design, management and operation of the transmission line. |
