摘　　要：本文介绍了三相交流异步电动机和同步电动机的几种启动方式,结合了各种启动方式的工程经验;例如三相交流异步电动机机的定子绕组启动电流参数、三相交流异步电动机机负序分量限制、三相交流同步电动机的启动过程和参数;从理论上分析了电机的过载和三相不对称状态;三相同步电机的投励失败对电机的不对称的影响;从技术角度分析了影响高压电机正常启动的故障原因:三相不对称不平衡状态,并基于三相交流电机的旋转磁场做了理论分析。This paper introduces several starting modes of three-phase AC asynchronous motor and synchronous motor, and combines the engineering experience of various starting modes;for example, the starting current parameters of stator winding of three-phase AC asynchronous motor, the limitation of negative sequence component of three-phase AC asynchronous motor, the starting process and parameters of three-phase AC synchronous motor;From the technical point of view, the causes of the failure affecting the normal start of the high voltage motor are analyzed: the three-phase asymmetric unbalanced state, and the theoretical analysis is made based on the rotating magnetic field of the three-phase AC motor.
