Flameproof high-voltage vacuum distribution equipment for mining is mainly used in power transmission and the power-off of colliery underground power supply system, it mainly comprises the flameproof enclosure that is provided with explosion-proof chamber, chamber door, and be arranged on the electric elements such as circuit breaker, electric current, voltage transformer and control assembly in explosion-proof chamber.The electric elements of existing flame-proof mine vacuum distribution equipment are that integral type is arranged on the bottom in explosion-proof chamber, cause explosion-resistant enclosure volume to need very large, space availability ratio is low, with wire, the parts of each electrical correlation are interconnected to realize inner each electric property of switch, the electrical layout of explosion-proof chamber inside is complicated, and circuit is mixed and disorderly, and electric property is unstable, have potential safety hazard, inspection and maintenance work also quite bothers.
Summary of the invention
For prior art above shortcomings, the object of this invention is to provide a kind of compact conformation reasonable, volume is little, and maintenance and service work be flameproof high-voltage vacuum distribution equipment for mining easily.
It is as follows that the present invention solves the problems of the technologies described above adopted technical scheme: a kind of flameproof high-voltage vacuum distribution equipment for mining, comprise base and explosion-proof casing, described explosion-resistant enclosure inside arranges ante-chamber and back cavity, described back cavity arranges He Xia chamber, chamber, described ante-chamber arranges machine core trolley, connects high-pressure vacuum breaker, voltage transformer, current transformer, intelligent measurement and control unit (microcomputerized overall protective device), piezo-resistance, isolation latch moving contact on described machine core trolley; Between described ante-chamber and back cavity, anti-explosion partition is set, isolation latch fixed contact pedestal is set on described anti-explosion partition; Described upper chamber arranges runs through bus; Described lower chamber arranges zero sequence current mutual inductor and control line outlet nozzle.
On described explosion-proof casing, chamber door is set, top, explosion-proof casing both sides arranges wiring cylinder, and top, explosion-proof casing right side arranges breaker closing handle, and below, explosion-proof casing right side arranges isolating switch handle;
Described chamber door is eyelet bolt presser type shutter structure, and reliable mechanical locking device is set on chamber door;
Liquid crystal window, button, state display window to change are set on described chamber door;
Described wiring cylinder below arranges line leading device.
Principle: electric elements are all contained on machine core trolley, when movement breaks down, can pull out dolly outside case, to overhaul and change standby movement.Microcomputerized overall protective device, has the defencive functions such as overload, short circuit, electric leakage, cable insulation supervision, has electric current, function displaying voltage, has fault category textual representation function.
Lower chamber is provided with a zero-sequence transformer and control line outlet nozzle, and user can draw control line and monitoring communication realizes the interlocking that He Tai and platform are controlled in a distant place.
Chamber door is eyelet bolt presser type shutter structure, and arrange reliable mechanical locking device (in running, can not open chamber door, only have breaker open operation, isolation latch in separation point position, remove casing with locking, door closure can be opened).Liquid crystal display window, state display window to change mouth and illumination are set on chamber door, seven buttons start, stop, leaking electricity, be shifted, confirm, reset.
On housing ante-chamber left side plate, respectively have an observation window, can see isolation latch deciliter situation, right side is provided with " dividing ", " closing " lock of isolation latch, manual-operating mechanism, circuit breaker manual brake separating operating mechanism.
Beneficial effect: volume of the present invention is little, lightweight, compact conformation, rationally, operation is directly perceived, flame proof chamber door adopts quick operating valve pattern, the inner handcart-type that adopts, all primary element high-pressure vacuum breakers, (electric current, voltage) instrument transformer and high-tension fuse and secondary component low-tension fuse etc. are all contained on handcart, and ,Wei simple to operate procuratorial organ just; There is advanced, perfect microcomputerized overall protection system; controlled circuit is had to short circuit, overcurrent, electric leakage, insulation monitoring, overvoltage, under-voltage and phase failure protection function, combine the self-checking function of possessing fault own, full Chinese display; simple, intuitive, and there is fault long-term memory function.And needn't open casing gate and can carry out adjusting of Protection parameters, be convenient to operation and improved the reliability of bulk supply.
