摘要
对某些水平与复合接地网的接地电阻公式进行了分析研究 ,并以文献 [1 ]提出的接地网的形状修正系数和文献 [2 ]提出的等效短形接地网的变换公式为依据 ,导出了任意形状的复合接地网接地电阻的解析公式。通过与计算机数值算法值的对比分析表明 ,所提出的解析公式的计算误差通常小于 1 0 %。
The article made an analysis and study on the earth resistance formula of some horizontal and compound earth screens and concluded the analytic equation for earth resistance of compound earth screen of arbitrary shape, based on the shape correction parameter of earth screen proposed in Document[1] and conversion formula for equivalent short shaped earth screen proposed in Document[2] The comparison with numeric computation by computer shows that the error rate of analytic calculation is often smaller than 10%
