【摘要】 本文以人工垂直接地极为例,依据相关计算,对影响冲击接地电阻的相关因素进行模拟,并从中指出其与冲击接地电阻之间所存在的关系,以此来更加全面、深入、系统化的去认识冲击接地电阻。通过对比两个有效长度的计算公式,指出其在现实工作中所存在的基本出入,以此为更好的开展防雷检测及接地工作提供指导与帮助。更多还原

【Abstract】 In this paper, taking the artificial vertical grounding pole as an example, according to the relevant calculations, the relevant factors that affect the impact grounding resistance are simulated, and the relationship between it and the impact grounding resistance is pointed out, so as to know the impact grounding resistance more comprehensively, in-depth and systematically. By comparing the calculation formulas of two effective lengths, it is pointed out that there are fundamental differences in the actual work, so as to provide guidance and assistance for better carrying out lightning protection detection and grounding work.更多还原
