摘要
主要针对民用建筑物内10/0.4 kV变电所接地的几种常见做法,通过对正常工作和故障时电流路径的分析,对比不同接地设计做法的优劣和问题所在,提出变电所接地设计原则,为工程设计提供参考。
For the common practices of 10/0.4kV substation earthing in civil buildings,the advantages and disadvantages of different earthing designs are compared and problems are discussed by analyzing current paths during normal operation and at fault,so as to put forward principles of substation earthing design to provide reference for engineering design.
