Low Insulation Resistance of Shaft and Its Treatment of CPR1000 Type Primary Pump Motor

主要介绍CPR1000型核电主泵电机轴绝缘电阻偏低及处理,并以某核电站为实例进行了解析,介绍了主泵电机的绝缘结构,同时系统地分析了轴绝缘偏低的原因及检查方法。

This paper mainly introduces the low insulation resistance of shaft of the CPR1000 type nuclear main pump motor and the processing. The main insulation structure of the pump motor is introduced and analyzed as an example of a nuclear power plant. Meanwhile, the reasons and inspection methods of low insulation resistance of shaft are systernaticaUy analyzed.
