摘要
以中小型异步电动机的故障特征分析为基础，运用对称分量法理论，采用时差与移相算法编程，实现了对正序、负序与零序电流的幅值的智能化检测，可基本处理中小型异步电动机的常见故障，具有广阔的应用前景。
Based on analyzing the fault characteristics of the asynchronous motors and using symmetrical components method an algorithm of time difference and shifting phasor is adopted to detect intelligently the current amplitude of positive,negative and zero sequence currents.With the proposed method,automatic diagnosis of most common faults for medium and small sized asynchronous motors can be realized.This method will have vast application prospect.
