摘　　要：现行有关电气设计参考书和实际工程对单、三相负荷的等效计算,均按住建部颁发的电气设计规范中的规定执行,但规范中并未对单相负荷的属性作具体规定,这给实际设计工作带来了一定的影响。通过理论计算和分析,提出了单相相负荷及线负荷等效为三相负荷的两种计算方法,并达到节能的目的。The equivalent calculating method of single-phase and three-phase in textbooks and practical engineering about electricity design and the both follow the electricity design norm issued by the Ministry of Construction. However, the norm doesn＇t give a specific guideline to the attribute of the single-phase load, which brought to some ＇affects in the practice. Based on the theoretical calculation and analysis, two calculating methods of the single-phase load and the line- to-line load to three-phase load was put forward, which aimed to be energy saving.
