Zusammenfassung:Through the analysis of soft-start ways which commonly used in medium voltage asynchronous motor, the soft start switching transformer topology of medium voltage asynchronous motor was given. It analyzed some key technologies of motor soft start, and gave the specific solutions. The problem of torque shock caused by the motor power factor angle and heavy start was analyzed especially. The main topological structures of the soft start devices about motor with large single power were given in the paper. Through the actual industrial applications of the soft start device, it showed that the device has reached the intended purposes, the device had a broad application prospect.
