Abstract: For improving working efficiency, shortening the power cut-off time during equipment maintenance period, and for ensuring the safety of personnel and equipment, intelligent power supply and distribution system is applied at Qiwu Coal Preparation Plant. With the control camera pointing right at the drawer-type loop indicator lamp, a reliable power supply switch on/off state can be ensured. Practice shows that with the use of the system, the labor intensity is greatly reduced, and it is possible to realize remote control of equipment power supply or cut-off (including industrial TV system) at unmanned power distribution rooms.
