摘要
应用对称分量法及电力拖动系统运动方程、结合实测结果 ,对三相异步电动机断相运行进行了理论分析 ,并得出断相运行时电动机电磁转矩和转差率的变化情况、电流与正常工作电流及与负载的关系 ,进而提出了设置断相保护的重要性及断相保护方案。
In this paper,a theoretical analysis has been made on the three phase asynchronous motors running with one phase cut off,through which the change of electromaganetic moment and the revolution difference rate of the motor and the velationship between the running current and the norminal current and the load are obtained. The necessity and related measures of protection are herewith presented.
