Design of protection and control power supply for mining explosion proof high-voltage distribution equipment
We analyzed the problems with the protection and control of underground mining explosion proof high-voltage distribution devices,which exist in the same source of power supply and power supply system.Proposed a method of independent power supply for mining.Analyzed and designed the protection and control power supply mode of the mining explosion-proof high-voltage distribution device.Designed an independent power supply for the mining explosion-proof high-voltage distribution device.And studied on the protection and control power supply mode of the mining explosion-proof high-voltage distribution device,and designed further protection and control power supply and power switching device.We achieved independent power supply with one in use and one backup for protection and control,ensuring the safe operation of the power supply system.At present,this power supply method has been applied in large underground mines of Lu'an Chemical Group and Jinneng Holdings Group.
