摘要
定子电流中频率为(1-2s)f1的边频带是分析异步电机转子绕组故障的基本特征量。本文分析了影响电机转子绕组故障特征量的因素,指出速度波动、负载转动惯量等与电机故障特征量的关系,提出了电机转子绕组故障特征量的修正方法。
s)f 1 current component in stator current is basic feature when ana lyzing asynchronous motor rotor winding fault. Factors affecting fault feature a re studied in this paper, and the relationships among fault feature and fluctuat ing speed, moment of inertia are given. Revisionary methods about rotor winding fault feature are proposed.
