摘要
介绍了施工临时用电系统接地的分类,并进行了比较选择。以图例的形式,通过计算各系统接地后的预期接触电压,用数据说明各系统接地的优缺点。指出TT系统更适用于临时施工场地,可为施工临时用电提供参考。
This paper introduced the classification of the temporary power system grounding,and the grounding systems were analyzed. By the form of legends,the expected contacting voltages of grounding systems were calculated,which explains the advantages and disadvantages of each grounding system. It was pointed out that TT system is more suitable for the temporary construction site. It could provide references for temporary power.
