直流电动机故障分析及防范措施

Direct Current Motor Fault Analysis and Measure

煤矿电机车牵引矿车运输中故障较多。尤其是电机车直流电动机,一旦发生电枢绝缘损坏或匝间短路,难以查找故障点,修理后也很难恢复原有的技术性能。分析了影响直流电动机使用寿命的原因,提出了防范措施。

In the coal mine electric locomotive hauhng mine car transportation the breakdown are many. Especially electric locomotive direct current motor, once has the armature insulation damage or the turn- to-turn short circuit, searches the fault point with difficulty, after the repair, is also very difficult to restore the original technical performance. Has analyzed the influence direct current motor service life reason, proposed the measure.
