摘要
直击雷、雷电感应以及雷电波侵入会直接引发配电网雷击过电压,从整体来看,配电网电压的绝缘水平较低,重构的网络结构较为繁杂,多数配电线路并没有设置避雷线、避雷器,部分配电线路的杆塔接地效果不好,无法有效地保护配电线路,导致了配电线路经常受到雷击而出现配电故障现象。因此为了保障电力系统的平稳运行,应重点对配电线路采取防雷保护措施。文章重点分析了与配电线路相关的雷电灾害,提出了关于架空配电线路的防雷措施。
Direct lightning strikes,lightning induction,and lightning wave intrusion will directly cause lightning overvoltages in the distribution network.On the whole,the insulation level of the distribution network voltage is low,and the reconstructed network structure is more complicated,and most distribution lines are not set up Lightning protection lines,lightning arresters,and some power distribution lines have poor grounding effects and cannot effectively protect the power distribution lines,resulting in frequent lightning strikes and power distribution failures in the power distribution lines.Therefore,in order to ensure the smooth operation of the power system,lightning protection measures should be taken for distribution lines.The article focuses on the analysis of lightning disasters related to distribution lines,and proposes lightning protection measures for overhead distribution lines.
