摘要

针对地网腐蚀后接地阻抗以及地表点位变化的问题

采用基于不等电位的节点电压法

计算了接地网腐蚀前后接地阻抗以及地表点位的变化情况。该方法可判断地网的腐蚀严重情况;可根据具体的腐蚀情况提供地网腐蚀后的改造方案。该模型对于入地电流频率在几十千赫兹下仍可考察地网的运行情况。

Abstract

According to change of grounding impedance and surface potential after grounding grid was corroded

this article calculated the changing condition of grounding impedance and surface potential based on node voltage method with unequal potential.The method can estimate the corrosive severity of grounding grid and provide the modification scheme for grounding grid corrosion.The model can judge the operation condition of grounding grid even when the frequency of earth current reaches dozens of kHz.
