Description
Technical field
The utility model relates to a kind of stringing electrical locomotive electric power system, particularly a kind of Underground metal & nonmetal mines drift stringing electrical locomotive DC power-supply system.
Background technology
The method of supplying power to of existing DC trolley locomotive adopts that to be suspended on the exposed stringing (exposed trolley) of drift near top board center be positive pole, and conveying track does the negative pole of direct supply, and electric locomotive utilizes pantograph to obtain direct supply from stringing.Because underground mine drift is shorter, width is less, this power supply mode, there is larger electrical shock safety risk, exist because of electric leakage causes stringing cannot the risk of normal power transmission.Stringing near top board center hinders the normal running of ore drawing workman.Metal and nonmetal mine safety code (GB l6423-2006) specifies: the trolley erection of electric haulage, the cross bracing wire of trolley wire clamp both sides, application porcelain insulator; O.2m the distance of wire clamp and porcelain vase is no more than; O.2m distance between wire clamp and back or rack beam is not less than; O.2m the distance of trolley and pipeline outer rim is not less than; Trolley and metal pipe line infall, application insulator separates.Therefore for DC trolley locomotive, to design a set of safe electric power system very important.
The patent No. is the Chinese patent of ZL200920189476.9, ZL201120305395.8, ZL2012207453 40.3, disclose the safe power supply equipment of stringing electrical locomotive, its essence is that Engine Powered Bow is not from stringing during power taking, stringing only has the power supply of 36V and following safety voltage, all whether there is lighting load electric current automatically to detect stringing electrical locomotive, judge whether supply regular power voltage (as 250V) power supply automatically to drop into.When electric locomotive obtains power for illumination from stringing, automatic system is closed a floodgate will drop into supply regular power, guarantee that electric locomotive enters normal operation.When electric locomotive is out of service and closedown is thrown light on, automatic system time delay disconnects normal power source, recovers 36V and following safety voltage power supply.Above-mentioned patent has the following disadvantages: when (1) stringing length is larger, for guaranteeing the safety of zones of different stringing, needs setting is no less than 2 supply lines' (a road stringing, road cable) in parallel, more than 2 patents and automatically controls stringing breaker device, therefore system architecture is complicated, investment is comparatively large, and maintenance management difficulty is larger; (2) when there being people to touch stringing, its electric current is greater than the action current lighting current of electric locomotive (during the 36V) of automatic system setting, and normal working voltage (as 250V) drops into by system automatically, and now workman will have electric shock life danger; (3) because of 36V and following safety voltage power time, electric locomotive drop into moment lighting current very little, the set action electric current of automatic system is very little.Because down-hole is moist, stringing hitch point is many, and its drain current may cause autonomous cruise speed system misoperation, and supply regular power power supply (as 250V) puts into operation by stringing power-off operatorless device by mistake.
