| 摘 要： | 与传统分析电能表驱动转矩观点不同，利用矢量分析方法推导出电能表转矩矢量与所加电压、电流、功率因数角关系，表明电能表转盘上存在水平转矩分量和垂直转矩分量。根据此转矩矢量讨论了感应式电能表产生计量误差及潜动的原因。此转矩矢量有助于进一步研究感应式电能表的性能。

| Abstract: | A vector analysis technique different from traditional views is applied to the study of the driving torque of an induction watthour meter The relationship between the torque on the disk of a watthour meter and such parameters as voltage,load current,power factor angle applied to the meter has been derived,indicating that there exist horizontal and vertical components of the driving torque on the disk Based on the above analyses,reasons for measuring error and stealthy movement are discussed Finally,it has been pointed out that the derived equations are useful in further study of electrical meters |
