交流电动机产生轴电流故障的分析

Failure Analysis of AC Motor Shaft Current

以中国铝业山西分公司热电分厂三期给水泵电机轴发生的损伤故障分析为例 ,分析了大中型交流电动机轴电流的产生和危害 ,提出了针对此类故障的防范措施。

Based on the case analysis of the faiture of AC motor shaft current of the third phas feed pump of Shanxi Company of China Aluminium, damages of shaft current generated in large and medium scaled AC motors are analysed and measures against fire are put forward as well.
