Background technology
Can produce heat in transformer running, transformer runs for a long time at high operating temperatures, can accelerate the aging of insulating material, affects insulation property and the electric property of transformer, thus affects the useful life of transformer.Practice shows, the air-flow of the heat formation of transformer shell inside is from bottom to cocycle, and a large amount of heats concentrates on the top of housing.Along with the increase of transformer capacity, the heat that transformer produces is also in increase, and this housing of changes persuing depressor will have higher heat-sinking capability.
Flameproof transformer is applicable to the place of flame proof requirement, particularly has methane blended gas and coal dust and has the underground coal mine of explosion hazard.It reaches explosion-proof requirement by the casing of high strength and effective explosion-insulation surface.Flameproof dry-type transformer comprises casing, is positioned at the transformer body of casing, electric original paper etc.Transformer body need be fixing to ensure that product is transporting with casing, load and unload and operating fail safe, reliability.In existing flameproof dry-type transformer, many employings track angle steel welds with inside the bellows of casing, lower clamping piece is connected by securing member the object reaching stationary transformer device body and casing with track angle steel, and unfixing between upper part of transformer body and casing.For the transformer that capacity is larger, such fixed form, its constant intensity does not reach requirement, and fail safe, reliability are poor.In order to solve above-mentioned deficiency of the prior art, the present invention proposes a kind of new technical scheme and solving the problems referred to above.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, a kind of Flameproof transformer is provided, be convenient to that installation, good heat dissipation effect, explosion-proof are strong, long working life, there is good economic benefit and social benefit, effectively can solve the problem in background technology.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of Flameproof transformer of the present invention, comprise oil discharging valve, valve, winding, iron core, oil filter, bushing, shunting switch, low-tension bushing, explosion stack, oil conservator, oil meter, radiator and nameplate; Described oil discharging valve side is provided with valve and described valve one end is fixedly connected with oil filter, described valve side is provided with winding, and winding top end surface and iron core close contact, described oil filter side is provided with bushing and described bushing one end is provided with low-tension bushing, is fixedly installed shunting switch between described bushing and low-tension bushing.
Further, described low-tension bushing one end is fixed with explosion stack.
Further, described oil conservator surface fixed installation oil meter.
Further, described radiator inside is provided with multiple cylindrical heat-radiating pipe.
Further, described nameplate is fixedly installed on fuselage one side surface.
The beneficial effect that compared with prior art the present invention reaches is:
1, compact conformation of the present invention, reduce the overall dimensions of transformer, space availability ratio is high, and explosion-proof effect is good;
2, the present invention effectively reduces the machinery consumption of motor, spuious consumption etc., improves electric efficiency, meets the design needs of high efficiency motor;
3, the amount of heat produced when the present invention effectively gets rid of transformer work, improves radiating efficiency;
4, cost of the present invention is low, is convenient to installation, good heat dissipation effect, long working life, has good economic benefit and social benefit.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.
In the accompanying drawings:
Fig. 1 is overall structure schematic diagram described in the embodiment of the present invention;
Number in the figure: 1, oil discharging valve; 2, valve; 3, winding; 4, iron core; 5, oil filter; 6, bushing; 7, shunting switch; 8, low-tension bushing; 9, explosion stack; 10, oil conservator; 11, oil meter; 12, radiator; 13, nameplate.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment: as shown in Figure 1, comprises oil discharging valve 1, valve 2, winding 3, iron core 4, oil filter 5, bushing 6, shunting switch 7, low-tension bushing 8, explosion stack 9, oil conservator 10, oil meter 11, radiator 12 and nameplate 13; Described oil discharging valve 1 side is provided with valve 2 and described valve 2 one end is fixedly connected with oil filter 5, described valve 2 side is provided with winding 3, and winding 3 top end surface and iron core 4 close contact, described oil filter 5 side is provided with bushing 6 and described bushing 6 one end is provided with low-tension bushing 8, is fixedly installed shunting switch 7 between described bushing 6 and low-tension bushing 8.
As a preferred technical solution of the present invention, described low-tension bushing 8 one end is fixed with explosion stack 9; Described oil conservator 10 surface fixed installation oil meter 11; Described radiator 12 inside is provided with multiple cylindrical heat-radiating pipe; Described nameplate 13 is fixedly installed on fuselage one side surface.
The present invention institute in use, is converted into heat by the loss produced in winding and iron core when transformer runs, and must dispel the heat in time, cause the accident in order to avoid transformer is overheated.The cooling device of transformer has been thermolysis.Vary in size according to transformer capacity, adopt different cooling devices.For the transformer of low capacity, winding and the unshakable in one's determination heat produced contact through transformer oil and inner wall of oil tank, and the contact of fuel tank outer wall and cool ambient air and cooling naturally, without the need to any additional cooling device.If transformer capacity is slightly larger, can weld radiating tube on fuel tank outer wall, with increasing heat radiation area, in order to make the air of oil conservator internal upper part keep dry, avoid the pollution of industrial dust, oil conservator is communicated with air by dehydrating breather.Dehydrating breather is built with calcium chloride or the impregnated silica gel of cobalt chloride, and it can absorb the moisture in air.When it makes moist to a certain extent, its color becomes pink from blueness.Fuselage is provided with radiator and explosion stack, can be improved the heat-sinking capability of transformer, then prevents that stopping transformer blasts.
