大中型船用电机轴电压测定方法的研究

Research on Shaft Voltage Measurement Method of Large and Medium-Sized Marine Motor

轴电压对电机轴承的破坏,引起了国内外许多电蚀事故,并造成船舶严重的设备损伤和船东的经济损失。通过研究不同参数类型船用电机的轴电压问题,介绍了轴电压产生原因、测量方法,实测装配不同类型轴承电机的轴电压,并提供了预防轴电压的实用方法。这有利于减少和避免轴电压产生所带来的机损危害。

The damage of shaft voltage to motor bearing had caused many electrical erosion accidents at home and abroad,and caused serious equipment damage and economic loss of ship owners. Through the research of shaft voltage problem of marine motor with different parameter types,the causing reason and the method of shaft voltage test were introduced,the shaft voltage of different type bearing motor were measured,a practical method for preventing shaft voltage was given. It could reduce and avoid the navigation damage caused by the shaft voltage.
