摘要
针对广西 110～ 2 2 0 k V输电线路近几年的运行状况 ,对过电压事故、雷击跳闸率、接地电阻及绝缘子损坏情况进行了调查和统计 ,就杆塔接地电阻、单避雷线和双避雷线保护对防雷效果的影响等进行了分析 。
In accordance with the operation of 110~220 kV transmission lines in Guangxi and accounted overvoltage faults,rate of outage by lightning,grounding resistances and damage of insulators,the author analyzed the influence upon effectiveness of lightning protection by footing ground resistance,single or double shield wire,and thus suggests the compositive technical measures for better lightning protection of the lines.
