摘要
介绍了阳煤集团35kV供电线路的运行概况,从地形地势的影响、现有防雷措施和线路绝缘配置等方面分析了线路雷害事故多发的原因,提出了拆除消雷器、两回线路采用不平衡绝缘配置和加装线路避雷器等防雷措施。实际运行结果表明,改造后的线路防雷效果较好。
The paper introduced operation situation of 35 kV power lines of Yangmei Coal Group,analyzed causes why lightning accident happened frequently in term of influence of topography,existing lightning protection measures and line insulation configuration,and proposed lightning protection measures such as removing lightning eliminators,using double-circuit transmission line unbalanced insulation configuration and installing line arrester.The actual running results showed that the reformed transmission line has better effect of lightning protection.
