Description
Technical field
The utility model belongs to mining speed regulation device apparatus field, especially a kind of flame-proof mine AC frequency control apparatus.
Background technology
In recent years, the development with control technology, computer technology, power electronic technology is rapid, and electrical technology will be faced with a revolution, and namely ac speed control technology substitutes DC speed regulation technology, digital control technology substitutes analog control technique.In modern industry controls, ac variable speed technology realizes energy savings, improves Controlling Technology stream to improve performance, the quality of product, improves the working environment of workers, the Main Means promoting scientific and technological progress and method.Ac variable speed technology is with him superior speed adjusting performance, startability and braking ability, the effect of high workload efficiency, High Power Factor and saves energy, be suitable for ability etc. advantage widely, be thus known as the speed adjusting technique most with application market and development space by enterprise both domestic and external.The application of current underground coal mine ac variable speed technology is still in the starting stage, all larger at the mechanical load such as blower fan, water pump, belt feeder, scrapper conveyor, coal-winning machine, compressor of underground coal mine, existing mining speed regulation device explosion insulation performance is poor, device production efficiency is low, energy waste is serious, if use variable-frequency control technique will energy-conservation, stepless speed regulation, the many aspects such as direct torque obtain remarkable effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of employing flameproof enclosure, explosion-proof performance is higher, the flame-proof mine AC frequency control apparatus that production efficiency is higher.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of flame-proof mine AC frequency control apparatus, be made up of flameproof enclosure, high powered device, switching device, main contactor, main transformer, AFE rectified feedback unit, hoisting mechanism, dipper crowding gear, slew gear, walking mechanism, brake mechanism, described high powered device is connected with switching device; Described switching device is connected with main contactor; Described main contactor is connected with main transformer; Described main transformer is connected with AFE rectified feedback unit; Described AFE rectified feedback unit is connected with hoisting mechanism, dipper crowding gear, slew gear, walking mechanism, brake mechanism respectively; Described high powered device, switching device, main contactor, main transformer, AFE rectified feedback unit, hoisting mechanism, dipper crowding gear, slew gear, walking mechanism, brake mechanism are all arranged in flameproof enclosure.
And described flameproof enclosure adopts cast aluminum alloy material.
And described switching device comprises on-load switch, isolating switch.
And the power source of described hoisting mechanism, dipper crowding gear, slew gear, walking mechanism, brake mechanism adopts adjustable frequency motor.
Advantage of the present utility model and good effect are:
1, the utility model adopts the flameproof enclosure of cast aluminum alloy material composition, once the electric elements in explosion-proof chamber are because of the gas in fault generation spark or arc ignition explosion-proof chamber or damp, explosion separation structure can block blast and propagate outside cabinet, explosion-proof performance is higher, is applicable to the high place of the gas bearing capacity such as colliery, iron ore and uses.
2, the utility model adopts adjustable frequency motor to power, and Shi Ge mechanism production efficiency is higher, more can adapt to Production requirement.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
As shown in Figure 1, a kind of flame-proof mine AC frequency control apparatus described in the utility model, be made up of flameproof enclosure, high powered device, switching device, main contactor, main transformer, AFE rectified feedback unit, hoisting mechanism, dipper crowding gear, slew gear, walking mechanism, brake mechanism, described high powered device is connected with switching device; Described switching device is connected with main contactor; Described main contactor is connected with main transformer; Described main transformer is connected with AFE rectified feedback unit; Described AFE rectified feedback unit is connected with hoisting mechanism, dipper crowding gear, slew gear, walking mechanism, brake mechanism respectively; Described high powered device, switching device, main contactor, main transformer, AFE rectified feedback unit, hoisting mechanism, dipper crowding gear, slew gear, walking mechanism, brake mechanism are all arranged in flameproof enclosure.
The utility model high powered device accepts voltage and processes the signal of telecommunication, exports to switching device, and closed according to signal of telecommunication Load adjustment switch or isolating switch of switching device, causes main contactor work.Main contactor connects main transformer adjustment voltage, and signal is inputed to AFE rectified feedback unit, AFE rectified feedback unit arranges hoisting mechanism, dipper crowding gear, slew gear, walking mechanism, brake mechanism work respectively.Flameproof enclosure all puts into flameproof enclosure the parts that may produce spark, electric arc and dangerous temperature, and flameproof enclosure makes the environment of device interior space and surrounding separate.There is gap in flameproof enclosure, because of electric equipment respiration and gas osmosis, inside is made to there is explosive gas mixture, when it is blasted, shell can bear the blast pressure of generation and not damage, simultaneously shell mechanism gap can cooling flame, reduce flame propagation velocity or stop accelerating chain, make the flame product of flame or danger can not pass through flame proof gap and light extraneous explosion environment, thus reach flame proof object.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model is not limited to the embodiment described in embodiment; every other execution modes drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
