Low Voltage Motor Avoiding Voltage Shock System Based on UPS

From the perspective of MCC,this paper introduced the application of constituting a special uninterrupted power supply system with the UPS in low voltage withdrawal,as the electrical source of control section.It avoided the unnecessary downtime of motor caused by voltage shocks as voltage fall off at split second,and made sure the unique uninterrupted power supply of the system.The system can guarantee continuity of the production at peacetime and be active immediately when the accident happened.Using the system can reduce enterprise's economic loss caused by unnecessary motor downtime.
