摘要
电机综合保护器利用电磁感应原理及电流参数平衡控制方法,对额定电流范围内的三相电动机的缺相故障(如电源缺相,熔丝断等)快速切断电源,从而保护电动机。
With the use of electromagnetic induction principle and the balance control method of current parameters,motor integrated protection can quickly cut off the power for three-phase motors within the scope of rated current with phase lack fault（such as the power phase,fuse breaking,etc.）,so it is able to protect the motor.
