Mine is with automatic segmentation power supply system

The utility model discloses a mine is with automatic segmentation power supply system, this system includes secure cable, the dc power tractor, the dc power tractor arrange in lay in on the rail of tunnel bottom, bare wire overhead line group, bare wire overhead line group is including the independent bare wire overhead line of multistage, and is adjacent distance between the independent bare wireoverhead line does not influence dc power tractor inertia streaks. This system is for easily producing the incident phenomenon to the bare wire overhead line, adopt that automatic remote sensing technology realizes one set overhead line safety power supply protection automatic control system in the pit. Can be based on concrete underworkings and reach the management expectancy respectively and realize the safe automatic power supply of direct current overhead line segmentation, the electrified scope and time of reduction direct current overhead line that can furthest realize the underground mine locomotive safety ope
