摘要
结合山东济南220 kV大桥变电站接地设计,对变电站接地网和接地材料选择,接地网布置方式及施工运行维护进行深入探讨。详细介绍了铜接地材料、接地网的不等间距布置方式以及降阻措施,阐述目前变电站接地网在设计中应该注意的问题及接地网施工具体方法。
The designing grounding grid of 220 kV Daqiao substation in Jinan Shandong province is discussed in this paper. According to that, the material selection and the arrangement of grounding grid and its maintenance are highlighted. The paper introduces the selection of copper material, the unequal distance pattern for the grounding grid and the method how to reduce the resistance of the grounding grid in detail. And also the paper points out the problem about the grounding grid we must pay attention to when designing and specific methods of construction.
