Description

A kind of impregnated vapour-cooled transformer

Technical field

The utility model relates to a kind of impregnated vapour-cooled transformer.

Background technology

In the transformer running, the winding of transformer-cabinet inside and meeting unshakable in one's determination produce loss, the heat part that loss produces has been used for promoting winding and own temperature unshakable in one's determination, another part is passed to the casing wall by transformer oil with convection current and heat conducting mode, thereby the part temperatures such as the pasta of transformer and winding are raise.Can make the too high aging quickening of insulating part that causes its transformer inside of winding temperature of transformer if do not take measures, insulation life shortens, and transformer can't normally move.

Evaporative cooling is as a kind of efficient novel cooling technology, and the heat that the latent heat of vaporization when it evaporates according to coolant is taken away main equipment makes its cooling, has flexible arrangement, heat exchange efficiency is high, the advantage such as remarkable, safe and reliable, economic easy care of lowering the temperature.At present, transformer based on evaporation cooling technique approximately is divided into fountain, isolated and impregnated, wherein, the impregnated vapour-cooled transformer is cooling with carrying out in winding and iron core immersion cooling fluid, general mixed liquor of using tetrachloro-ethylene and transformer oil is as cooling fluid, but this medium has inflammability and corrosivity.And, the present most complex structure of impregnated transformer, inhomogeneous cooling is even, and cost and maintenance cost are higher.

Summary of the invention

The purpose of this utility model is to provide a kind of impregnated vapour-cooled transformer, and simple in structure, cost is lower, and is easy to maintenance, and nonflammable, and is also not perishable.

The technical scheme that realizes above-mentioned purpose is:

A kind of impregnated vapour-cooled transformer, comprise casing, iron core and winding, and described impregnated vapour-cooled transformer also comprises condenser, vapor uptake and condensate descending, wherein:

Described memory box has condensate liquid, and described iron core and winding are immersed in described condensate liquid;

Described bottom half has a condensate liquid import, and top has a steam (vapor) outlet;

Described condenser is in tilted layout above described casing, and the bottom surface that this condenser tilts has an import and an outlet, and the level height of outlet is lower than the level height of import;

Described condensate descending is connected the condensate liquid import of described bottom half and the outlet of described condenser bottom surface;

Described vapor uptake is connected the steam (vapor) outlet at described casing top and the import of described condenser bottom surface.

Above-mentioned impregnated vapour-cooled transformer, wherein, described condensate liquid is that liquid is closed in the fluorine carbonization.

The beneficial effects of the utility model are: the utility model, owing to using the fluorine carbonization to close liquid as cooling fluid, has nonflammable and uncorruptible character.Simultaneously, the utility model utilizes difference in height and transpiration-cooled rule, simple designs structure, cost is lower, and is easy to maintenance, possesses high practicality.

Description of drawings

Fig. 1 is the structural representation of impregnated vapour-cooled transformer of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

See also Fig. 1, impregnated vapour-cooled transformer of the present utility model, comprise casing 1, iron core 2, winding 3, condenser 4, vapor uptake 5 and condensate descending 6, wherein:

Casing 1 internal memory contain condensate liquid, iron core 2 and winding 3 are immersed in condensate liquid; In the present embodiment, condensate liquid is that liquid is closed in the fluorine carbonization;

Casing 1 bottom has a condensate liquid import 11, and top has a steam (vapor) outlet 12;

Condenser 4 is in tilted layout above casing 1, and the bottom surface that condenser 4 tilts has an import 41 and an outlet 42, and exports 42 the level height level height lower than import 41, so that condensed liquid can flow out from exporting 42;

Condensate descending 6 is connected the condensate liquid import 11 of casing 1 bottom and the outlet 42 of condenser 4 bottom surfaces;

Vapor uptake 5 is connected the steam (vapor) outlet 12 at casing 1 top and the import 41 of condenser 4 bottom surfaces.

In the utility model, condensate liquid is in the heat absorption vaporization of the heater surface of winding 3 and iron core 2, and the steam after vaporization rises to the condenser 4 of casing 1 top by vapor uptake 5, flows out by outlet 42 after liquid is returned in condensation in condenser 4, through condensate descending 6 to casing 1, periodic duty.Therefore, utilize difference in height and transpiration-cooled rule to design the utility model, make simple in structure, with low cost.

In the present embodiment, the type of cooling of condenser 4 is water-cooled, and namely cooling water flow, through condenser 4, is realized cooling.
