摘　　要：对于多电压等级的要求,即在满足电机功率的情况下,采用电机附加的电机绕组接线转换柜,改变电机绕组的接线形式以对应不同的电压等级。满足多容量等级被试变频器就是在电机最大功率已定的前提下,最大限度地降低电机的起动转矩,减小被试变频器在起动电机时的功率输出。The requirement of multi-voltage level is that, in the case of satisfying output power of motor, the motor windings connection conversion cabinets attached with the motor are used to change connection methods of motor windings so as to correspond with different voltage levels. Meeting requirement of the tested frequency converter with multi-capacity levels is that, under the premise of determination of max. output power of motor, the starting torque of motor is minimized to reduce output power of the tested frequency converter while starting the motor.

关 键 词：多电压等级 多容量等级 绕组接线转换柜 起动转矩
