摘要
通过有限元分析软件仿真计算安装架空地线前后电场强度分布,分析安装架空地线降低雷电直接雷原因以及从最大强度角度出发分析降低直接雷雷击概率,结合不同地形地貌分析安装架空地线前后感应电压变化得出安装架空地线的整体防雷效果,同时提出安装架空地线应采取的接地方式、防护措施和避雷器典型型式建议。
The distribution of electric field strength before and after the installation of overhead ground wire is simulated and calculated by finite element analysis software,and the reason for reducing direct lightning strike of overhead ground wire is analyzed.At the same time,the probability of direct lightning stroke is reduced from the maximum intensity analysis.The change of induced voltage before and after the installation of overhead ground wire is analyzed from different landforms,and the lightning protection effect of the installation of overhead ground wire is obtained.At the same time,the grounding mode,protective measures and typical type of lightning arrester should be adopted for the installation of overhead ground wire are proposed.
