摘要
Abstract
Transmission lines are an important part of the power system,transmitting electricity from re-mote energy bases to load centers.The transmission distance of transmission line can reach more than 200 km,and the terrain,climate and environment along the way are complex and changeable,making it easy to be struck by lightning.How to improve the lightning resistance level of transmission lines and re-duce the trip rate of lightning strikes is an urgent problem to be solved.Taking 330 kV double-circuit transmission line on the same tower as an example,the author analyzes the influence of key factors such as impulse grounding resistance,coupling grounding and arrester configuration on the lightning resistance level of the transmission line.The research results are helpful to guide the design of lightning protection scheme,and have certain reference value for improving the lightning resistance level of transmission lines.关键词
