摘要

一种用电缆与电源连接的断开电动机绕组绝缘缺陷识别的新方法。为了评估电机的状态，在其中一个电机连接相上施加矩形电压脉冲。对缺陷电机的数学模拟和实验研究表明，在后续的相间电容放电过程中会出现相间交流电压。这种电压的频率是缺陷及其起源位置的函数。该方法适用于所有运输车辆和工业厂房中采用电缆连接的三相电机。

Method for automatic assessment of electric motor condition before its startup

A new method for identification of defects in winding insulation of switched off electric motors connected by a cable to a power source. To assess condition of a motor, rectangular voltage pulse is applied to one of motor connection phases. Mathematical simulation and experimental studies of motors with defects have shown that AC voltage between phases emerges at the subsequent discharge of interphase capacitances. Frequency of such voltage is a function of defect and location of its origin. This method can be applied for three phase motors of all transport vehicles and industrial plants motors, which are cable jointed.
