接地网电流分布的测量与分析

Measurement and analysis of current distribution in grounding grids

由于在实际接地网中测量接地网电流是不可能的,因此,提出了一种实验室接地模拟的方法来分析实际接地网的电流分布,即在实验水池中,用电量隔离传感器测量接地网的电流分布,测出不同接地网———单根垂直接地体、十字形接地网、水平接地网、复合接地网的电流分布,所得的实验结果为研究接地网中的电位分布及接地网的设计提供较准确的科学数据。

In view of the impossibility of current measurement in actual grounding grids, a method of analyzing current distribution in actual grounding grids by simulation experiments in the laboratory is introduced in this paper. Current distribution in grounding grids is measured by the isolated sensor of electricity in the experimental pool. A series of experimental data are obtained by measuring different grounding grids including single vertical earth electrode, cross grounding grid, vertical grounding grid and complex grounding grid, thus providing a basis for the design and potential distribution analysis of grounding grids.
