摘要
由多级回馈功率单元串联组成的大型低速同步电动机高压变频器,其单机容量可达到15MW以上,额定频率在10Hz左右,具有低速大扭矩的特点,适合于拖动装机容量达6～8MW的大型矿井提升机。
Multi-stage feedback power units constitute the high-voltage frequency inverter for large-scale low-speed synchronous motor.It has the features of low speed and great torque with capacity of over 15MW and rated frequency of 10 Hz or so,and is especially suitable for driving large-scale mine hoists with installed power of 6～8 MW.
