摘　　要：随着科学技术的发展,我国也改变了变电站接地体的所用材料,逐渐向更好,更优质的材料使用中过渡,比如开始将铜材作为其材料主体。文章将从发电厂和变电站接地网使用材料的选择以及现有的情况出发,讨论分析出在发电厂、变电站铜材接地网使用中应该注意的一系列问题。并尝试在这些问题中找到解决方式。In our country,when the grounding grid material is gradually changed to copper,as the equipment under the ground,some iron equipment will no longer be used as the material of the grounding grid.This article will start from the selection of materials used for grounding grids in power plants and substations and the current situation,discuss and analyze a series of issues that should be paid attention to in the use of grounding grids in power plants and substations.And try to fi nd solutions to these problems.It involves pollution problems caused by various problems,as well as some problems existing in the equipment in use.It has been over a hundred years for the grounding grid made of copper as a material abroad.With the development of science and technology,my country has also changed the materials used for the grounding body of substations,and gradually transitioned to the use of better and higher-quality materials,such as the beginning of copper as its main material.
