摘要
基于等值土壤电阻率的概念,导出了三层土壤中接地棒接地电阻解析计算公式。基本方法是把三层土壤中接地棒电阻的问题简化为二层土壤中接地棒接地电阻的计算。验证计算结果表明:解析公式与计算机数值算法结果比较,计算误差小,有实用价值。
Based on the concept of soil equivalent resistance ratio,analytic formula of grounding resistance of grounding rods in 3-layer soil is deducted. The basic principle is to simplify grounding resistance of grounding rods in 3-layer soil to one in 2-layer soil. The results show that calculating error of this analytic formula is less and has more actual value compared to computer algrothim method.
