对民用建筑中变电站及变压器接地的探讨

Discussion on Earthing of Substation and Transformer in Civil Building

对现时常用的几种变电站及变压器接地处理方法进行分析,指出不足之处,即:其接线柱上的机械负荷过大,无法准确检测中性线上总电流,及总剩余电流等等。提出了作者认为变压器的保护接地、工作接地应该的做法。

Often-see earthing and transformer currently are ways of substation analyzed. Their deficiency are pointed out, i.e., too much machine load on connection terminal, unable to meter precisely total current of neutral llne as well as total residual current. Implementation way of system earthing and protective earthing of transformer are suggested.
