The mining flame-proof type reactive power automatic compensation device structurally comprises a power box and a capacitor box which are mutually independent and connected through an externally-connected electric cable; housings of the power box and the capacitor box are both flame-proof housings; a reactor, a disconnector, a control transformer, a fuse and a voltammeter are arranged in the power box; and a vacuum contactor, a capacitor, a reactive compensation controller and a circuit board are arranged in the capacitor box. The mining flame-proof type reactive power automatic compensation device disclosed by the utility model can be used in a coal mine well with an explosion hazard, can automatically compensate reactive power of a motor, the transformer or a low voltage power supply system, is provided with a split structure, dissipates heat well and requires a low cost.
Description
Technical field
The utility model relates to a kind of power equipment, specifically a kind of flame-proof mine reactive power automatic compensator.
Background technology
The flame-proof mine reactive power compensator that generally uses now generally is that reactor, capacitor and other all electric elements are installed in the flame proof housing.Because down-hole fully mechanized coal face high-power electrical equipment is more concentrated; For power factor controlling in reasonable range; The capacitance that the reactive power compensation of configuration is used will be bigger; What need that the reactor of larger capacity suppresses to produce when electric capacity drops into shoves, and can produce great amount of heat during jumbo reactor operation.Because the shell of antiknock device is an enclosed construction; Distributing of device interior heat is very difficult; (certificate is measured in hot environment certainly will to cause capacitor; Equipment cavity internal temperature can reach 60 ℃) down work, cause the electric elements such as capacitor, idle compensating control can't operate as normal, the security of operation that has a strong impact on electric component with shorten its useful life.
In order to guarantee the security of operation of down-hole reactive-load compensation equipment; The like product that most domestic manufacturers produce; For the control appliance internal temperature rise; Can only passive selection equipment intermitten operation working method---and that this often occurs in on-the-spot load or burden without work is maximum, needs most when carrying out reactive power compensation, this also just loses the meaning of configuration reactive-load compensation equipment.
In addition, reactor and capacitor are installed in the same housing, certainly will cause shell huge, heavy, be difficult to transportation and installation; For structural strength and the explosion-proof effect that guarantees shell, need to strengthen the thickness of hull plate, except that increasing considerably purchase cost, the bending, welding, explosion-proof processing etc. of returning housing bring very big difficulty.
The utility model content
The technical assignment of the utility model is to above weak point; Providing a kind of can use having under the coal mine of explosion hazard; Can carry out reactive power automatic compensation to motor, transformer or low-voltage power supply system, divide body structure, good heat dissipation, a kind of flame-proof mine reactive power automatic compensator that cost is low.
The utility model solves the technical scheme that its technical problem adopted: comprise the separate power supply box and the capacitor box that pass through the external cable connection that separates; The housing of power supply box and capacitor box is the flame proof housing; Be provided with easy generation heat in the power supply box but heat-resisting electric component, be provided with the electric component that heating is little and temperature influence is big in the capacitor box.
Easy generation heat in the described power supply box but heat-resisting electric component is reactor, isolating switch, control transformer, fuse, voltmeter and ammeter.
The electric component that heating is little and temperature influence is big in the described capacitor box is vacuum contactor, capacitor, idle compensating control and wiring board.
The utility model is divided in easy generation heat and heat-resisting device in the reactive power compensation circuit in the power supply box, and other device is contained in the capacitor box.Reactor as the main devices independent installation in the power supply box that designs; Give follow-up circuit supply; Avoided concentrating of heater members; Can better dispel the heat, solve in the same Flameproof box too high and capacitor of temperature rise and the power factor controller problem of job insecurity at high temperature, make the switching loop better put into operation.The temperature rise of reactor can not have influence on capacitor and idle compensating control, makes that their work is more stable.The flame proof housing makes the electric spark and external environment isolation that circuit switch to produce, the damp under the coal mine of can not igniting and the accident of blasting.Power supply box also has the function to the capacitor box power supply simultaneously, through external cable, can realize very easily that two power supply boxs are connected with the interior electric original paper of capacitor box, are combined into the complete reactive-load compensation equipment of a cover.
A kind of flame-proof mine reactive power automatic compensator of the utility model is compared with prior art, has the following advantages:
1, isolates main heating device reactor, make the temperature rise of reactor not influence the work of capacitor and power factor controller;
2, the smaller volume that separately makes each explosion-proof cabinet of reactor and capacitor, production cost reduces, and the process for machining of explosion suppresion surface is better controlled;
3, the transportation under the narrow and small mine in space is more convenient;
4, the independent installation of reactor makes simple to the maintenance of whole reactive power compensator; Thereby, have good value for applications.

Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is the structural representation of the utility model power supply box;
Accompanying drawing 2 is the structural representation of the utility model capacitor box.
Among the figure: 1, power supply box, 2, capacitor box, 3, fuse, 4, reactor, 5, isolating switch; 6, control transformer, 7, voltmeter and ammeter, 8, vacuum contactor, 9, capacitor; 10, idle compensating control, 11, wiring board, 12, the electric capacity protector, 13, the flame proof housing.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
A kind of flame-proof mine reactive power automatic compensator of the utility model; Its structure comprises the separate power supply box 1 and capacitor box 2 that pass through the external cable connection that separates; The housing of power supply box 1 and capacitor box 2 is flame proof housing 13; Be provided with easy generation heat in the power supply box 1 but heat-resisting electric component, be provided with the electric component that heating is little and temperature influence is big in the capacitor box 2.
