10kV配电线路防雷分析与海宁地区防雷讨论

Analysis and Discussion on Lightning Protection of 10 kV Distribution Line

介绍10 kV配电线路遭受雷击的主要原因,详细地介绍绝缘导线、避雷绝缘子、加装线路避雷器、合理运用自动重合闸等常用的防雷措施,从10 kV配电线路可能遭受的雷击类型,到现今采用的防雷措施进行讨论,并根据海宁的地貌特征来进行特殊的接地网改造,探讨配电线路防雷的优化方案。

This paper introduces the main causes of lightning strike on 10 kV distribution lines. The common lightning protection measures such as insulated conductor, lightning insulator, installation of line lightning arrester and rational application of automatic reclosing are introduced in detail. The possible lightning strike types of 10 kV distribution lines and the lightning protection measures adopted today are discussed. According to the geomorphic features of Haining, the special grounding grid shall be reconstructed. The optimization scheme of lightning protection for distribution lines is discussed.
