The oil-immersed type transformer is characterized in that the side face of the oil tank is provided with a gasbag chamber, the gasbag chamber is communicated with the oil tank, a gasbag is arranged in the gasbag chamber, and the inside of the gasbag is sealed and is also provided with gas. According to the oil-immersed type transformer disclosed by the utility model, the gasbag chamber is added, the pressure of the transformer oil is automatically regulated by the gasbag of the gasbag chamber, an oil conservator and the like are reduced, the cost is lowered, and the safety performance and the service life of a product are enhanced.
Description
Technical field
The present invention relates to a kind of power transmission and transformation technical field, especially a kind of oil-filled transformer.
Background technology
Oil-filled transformer generally includes fuel tank and is immersed in the device body of transformer oil and conservator etc., and the conservator of transformer is general all above the transformer body, utilizes constantly fuel feeding of deadweight.When the volume of transformer oil along with the temperature expansion of oil or when reducing, conservator plays the adjusting oil mass, guarantees frequent oil-overflow effect in the oil tank of transformer.When the volume of transformer oil along with the temperature expansion of oil or when reducing, conservator plays the adjusting oil mass, guarantees frequent oil-overflow effect in the oil tank of transformer., the transformer of band conservator is along with pasta fluctuation air is discharged and inspiration in the case lid seam, and because upper strata oil temperature is very high, makes oil oxidation and making moist soon.The ground oxidation and making moist of being overrun easily of the transformer oil of conservator so just influences the performance of transformer, the reduction transformer life.In addition, conservator also has the cost height, and shortcomings such as inconvenience are installed.The oil conservator of common middle-size and small-size oil-immersed type transformer mounting strap oil sealing dehydrating breather, transformer communicates with atmosphere by dehydrating breather, but the hygroscopic effect of silica gel is limited in the dehydrating breather, and the humid air in the atmosphere can enter into transformer oil unavoidably, cause transformer oil ageing, dielectric strength reduces.Therefore the user needs often to change silica gel and handle transformer oil, needs a large amount of energy periodic maintenance of cost and maintenance transformer.
Also have a kind of can be not with the full-sealed transformer of conservator, full-sealed transformer adopts corrugated tank, utilize bellows wall in the certain pressure scope, strain to take place, volume with the variation corrugated tank of pressure can change, hold the expansion of transformer oil, solved the problem that transformer oil expands with heat and contract with cold.Like this, transformer oil and air are isolated fully to be difficult for wearing out, and has prolonged the useful life of transformer, has significantly reduced the maintenance work of transformer simultaneously.; in actual motion; it is limited that bellows wall is regulated pressure limit; rising along with tank internal pressure; the amount of bellows wall generation strain also increases thereupon, and after pressure surpasses certain value, expendable distortion will take place bellows wall; bellows wall can be broken when serious, jeopardizes the safe operation of transformer.
In full-sealed transformer was made, it was the transformer oil in the fuel tank all not to be filled it up with that a kind of way is also arranged, and leaves certain space and be filled with gas on the pasta on fuel tank top, utilizes this part gas to regulate the corrugated tank pressure inside.But do like this, just have the part transformer lead not immerse transformer oil, make to have the decreasing insulating at this position certain quality hidden danger and increase the transformer manufacturing cost.In addition, owing to there is not other regulating measure, bellows wall can be too much because of the strain number of times, and cause the life-span of corrugated plate to descend.
Summary of the invention
The utility model main purpose is to overcome the deficiency that above-mentioned prior art exists, a kind of oil-filled transformer of adjustable pressure is provided, can solve the change in volume problem that transformer oil expands with heat and contract with cold and causes, regulate the pressure of transformer oil automatically, rational in infrastructure, technology is simple.
The technical scheme that technical problem adopted that the present invention solves is:
Oil-filled transformer, comprise fuel tank and device body, the device body comprises iron core and the coil on the iron core, transformer oil is housed in the fuel tank, the device body is immersed in the transformer oil, it is characterized in that being provided with gasbag chamber in the side of fuel tank, and gasbag chamber communicates with fuel tank, be provided with air bag in the gasbag chamber, seal and be provided with gas in the air bag.Utilize the transformer oil coefficient of expansion different, play the self-regulating effect of pressure with gas: when the pressure of transformer oil increases, the smaller volume of the gas in the air bag; When the pressure of transformer oil reduced, it is big that the volume of the gas in the air bag becomes.This shows that two identical transformers are under the environment of same variation, if wherein one air bag is housed, then the excursion of the maximum pressure that bears of this transformer inside and pressure all will be less than the transformer of not adorning air bag.In the transformer manufacture craft, just can at first fill it up with the transformer oil of oil tank of transformer, to guarantee that transformer lead all immerses transformer oil, improve its insulation property; For hermetically sealed corrugated tank transformer, air bag can reduce bellows wall meeting elastic deformation amount, prevents that bellows wall from producing expendable distortion, improves the life-span of corrugated plate in addition.
The beneficial effects of the utility model are: the utility model has increased gasbag chamber, and the air bag of gasbag chamber is regulated the pressure of transformer oil automatically, reduces conservator etc., reduces cost, and has improved security of products energy and useful life.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is the contour structures schematic diagram of the utility model embodiment.
Among the figure: 1, fuel tank 2, corrugated plate 3, device body 4, transformer oil 5, air bag 6, gasbag chamber
Embodiment
The utility model embodiment is an example with hermetically sealed corrugated tank transformer, as shown in Figure 1, a kind of oil-filled transformer, comprise the fuel tank 1 and the device body 3 that are provided with corrugated plate 2, device body 3 comprises iron core and the coil on the iron core, and transformer oil 4 is housed in the fuel tank 2, and device body 3 is immersed in the transformer oil 4, the side of fuel tank 1 is provided with gasbag chamber 6, gasbag chamber 6 communicates with fuel tank 1, is provided with air bag 5 in the gasbag chamber 6, seals and be provided with gas in the air bag 5.
Because sealing is provided with gas in the air bag 5, when the variation of the pressure of transformer oil 4, the expansion of air bag 5 and contraction, the space size of air bag 5, the volume of air bag 5 changes simultaneously, so just plays the regulating action of pressure.In the transformer manufacture craft, just can at first fill it up with the transformer oil 4 of oil tank of transformer 1, to guarantee that transformer lead all immerses transformer oil 4, improve its insulation property; Air bag 4 can reduce bellows wall meeting elastic deformation amount in addition, prevents that bellows wall from producing expendable distortion, improves the life-span of corrugated plate.
The utility model also can adopt on the transformer of other radiators such as fin, radiating tube, and structure is with embodiment 1.
