摘　　要：高压电机具有功率大和承受冲击能力强等优点,主要应用于驱动水泵、风机、破碎机和轧钢机等设备中。由于高压电机额定电压较高,因此对电机绝缘系统的质量及稳定性有较高的要求。高压电机功率大,体积相对较大,如使用不当造成故障,则会发生较高的维修费用。为此应对高压电机使用和保养维护予以高度重视,加强电机运行时的在线监测,预估故障发生几率,有效避免因故障停机而造成的经济损失。The high-voltage motors possess the advantages of large power and strong disturbance impact capability, mainly being used in such equipments as direct driven pump, blower, crusher and rolling batch. Because of higher rated voltage of the HV motor, higher quality of the insulation system of the motor as well as its stability are required. And because of large power of the HV motor with rather great volume, higher maintenance expense is cost in case that failure occurs due to improper application. So, application and maintenance on the HV motor should be highly valued, on-line monitoring during motor operation should be reinforced, chance of faults occurrence should be estimated, to effectively avoid the economic loss by downtime.
