摘要
结合福州城市中心区某110kV地下变电站工程的设计建设,论述地下变电站接地网的设计方法。从接地网总体布置方案设计、接地极材料选型、接地网接地电阻值计算、最大接触电位差及最大跨步电位差校验等基本方面,进行地下变电站接地网设计。
This paper discusses the grounding system design method for underground substation in downtown district base on the construction of one 110 kV substation project in Fuzhou. The discussion consists of some basic aspects of grounding design such as the arrangement of ground grid,the selection of conductors and connections,the calculation of ground resistance and the evaluation of step & touch voltage etc.
