摘要
降低杆塔冲击接地电阻是输电线路防雷的重要措施。在分析研究国内外接地装置冲击特性理论分析方法的基础上,运用CDEGS电磁仿真软件研究了土壤电阻率、冲击电流幅值以及水平分层土壤对立体式杆塔接地装置冲击接地电阻的影响,并给出了一些常用的冲击降阻措施,可为输电线路接地工程提供参考。
Based on the analysis of the theoretical analysis methods of the impact characteristics of grounding devices at home and abroad,the influence of soil resistivity,impact current amplitude and horizontal layered soil on the impact grounding resistance of three-dimensional tower grounding devices was studied by using the CDEGS electromagnetic simulation software.Some common measures of impulse resistance reduction were put forward,which can provide reference for transmission line grounding engineering.
