摘　　要：采用准实证研究与定量分析相结合的方法。利用CX10测试仪对高压电动机定子电流检测,再利用EA软件对其电流频谱进行分析,首先确定该电动机电流线频率峰值(FL),再通过相关计算确定该电动机的极通过频率(FP),计算FL与FP的差值(dB down),根据之前总结的经验值dB down值判断该电动机转子是否存在断条,再评估转子的状态,即严重程度。The method of combining quasi empirical research and quantitative analysis is adopted.The CX10 tester is used to detect the stator current of the high-tension motor,and then the EA software is used to analyze its current spectrum.First,determine the current line frequency peak(FL)of the motor,and then determine the pole pass frequency(FP)of the motor through related calculations.Calculate the difference between FL and FP(dB down).According to the previously summarized empirical value and the dB down value,determine whether the motor rotor has broken bars,and then evaluate the state of the rotor,i.e.severity.
