摘　　要：介绍了多用户电能表的原理,着重分别分析了两种电能转换方式和两种电能计量方法,并比较其不同。对于多用户共用部分线路电压分户供给方式所产生的不同于普通电子式单相和三相电能表的误差影响量,我们归结为相间影响、断相影响、户间影响。针对这些设计的特性产生的干扰,给出较好的解决方案。This paper described the principle of muhi-users electromechanical meter, analyzed two energy conversion styles and two methods of energy measurement, and compared their differenees. Multi-users electric energy meter is a kind of different energy meter; there is error influence quantity different from common single-phase and tri-phase electronic meters. It included phase influence, phase failure influence, users influence and so on. The text also provided a perfect option to resolve the interaction between users which was interference in the design.

关 键 词：多用户电能表 两种电能转换方式 两种计量方法 户间影响的产生
