摘要
提出了一种测量和分析接地体工频下接地电阻和电流分布的模拟试验法;尝试在电解池中运用电量隔离传感器来测量接地体中的电流分布;通过测量和分析按几何比例缩小的接地体模型的接地电阻和电流分布所得的数据,显示了地网的散流及其轴向电流分布规律,测量点相连支路越多则散流效果越差,垂直接地体每小段导体散流量随其深度增大。为研究地网的热稳定性和地网设计提供参考。
A method of measuring and analyzing current distribution and ground-resistance of the grounding electrode under the power frequency by the simulation experiment in the laboratory is presented in this paper. The isolated sensor of electricity is used in measuring the current distribution inside the grounding electrode in the electrolysis bath. Through measuring and analyzing the ground resistance and the current distribution of the grounding electrode that is dwindled in size according to the geometrical proportion, a series of useful data that reveal the law of current distribution and the law of the dissipation of current are given. This is very helpful not only to the research of the heat stability but also to the design of the grounding grid.
