Abstract
The utility model discloses an oil tank for transformers, which comprises cooling oil, a tank body, a magnetic shield, fasteners and an insulating oil passage, the cooling oil is stored in the tank body, the fasteners are used for fastening the magnetic shield on the tank body, the insulating oil passage is located between the tank body and the magnetic shield, the magnetic shield tightly supports the insulating oil passage on the tank body, and a certain gap is arranged between the magnetic shield and the tank body. An earth base is arranged on the tank body, and an earth lug which is electrically connected with the magnetic shield is arranged on the earth base. The tank body is closely adjacent to the magnetic shield with the insulating oil passage, so that the oil passage extends along the height direction of the inner sidewall of the tank body. The structure is adopted by the oil tank, the heat of the magnetic shield can be dissipated to four sides from three sides, so the heat-dissipating effect is better; and meanwhile, since the tank body is not in direct contact with the magnetic shield, the heat produced by the magnetic shield cannot be directly conducted to the tank body.
Description
Technical field
The utility model relates to a kind of fuel tank of transformer.
Background technology
In the transformer running, when the leakage flux that winding produces is crossed casing, in casing, produce stray loss, cause body partial overheated simultaneously.For being reduced in the stray loss on the transformer-cabinet and reducing the local overheating situation, generally by increasing magnetic screen at the transformer-cabinet inwall.Usually the set-up mode of magnetic screen as shown in Figure 1, magnetic screen has only three heat radiations, magnetic screen directly contacts with casing, the heat of magnetic screen directly conducts the heat accumulation that causes casing to casing.
The utility model content
At the problems referred to above, main purpose of the present utility model provides a kind of fuel tank and installation method thereof of transformer, reduces the temperature of casing when it can be reduced in the magnetic loss of casing.
In order to solve an above-mentioned difficult problem, the scheme that the utility model is taked is a kind of fuel tank of transformer, it comprises cold oil, have the casing of cold oil, magnetic screen, be used for magnetic screen is stuck in fastener on the casing and the insulation oil duct between casing and magnetic screen, described magnetic screen pushes against described insulation oil duct on described casing, has certain interval between described magnetic screen and the described casing.
Preferably, described casing is provided with grounding base, and described grounding base is provided with the ground strip that is electrically connected mutually with magnetic screen.
Preferably, described casing is close to mutually with described magnetic screen.
Preferably, described insulation oil duct is along extending on the madial wall short transverse of casing.
The utility model adopts above structure, and the heat radiation of magnetic screen is extended to the four sides from three heat radiations, and radiating effect is better, directly contact between casing and the magnetic screen simultaneously, and the heat of magnetic screen generation can not be directly conducted to casing.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be those skilled in the art will recognize that protection range of the present utility model is made more explicit defining.
Transformer generally comprises primary coil, secondary coil and iron core, and primary coil and secondary coil change alternating voltage by electromagnetic induction.In primary coil and the secondary coil course of work, produce a large amount of leakage fluxs, when these leakage fluxs are crossed casing, in casing, produce stray loss, cause body partial overheated simultaneously.For being reduced in the stray loss on the transformer-cabinet and reducing the local overheating situation, generally by increasing magnetic screen at the transformer-cabinet inwall.As shown in Figure 2, the utility model discloses a kind of fuel tank of transformer, it comprises cold oil, the casing 1 of cold oil is housed, insulation oil duct 2, magnetic screen 4.
Have cold oil in the casing 1, cold oil can insulate certainly and flow in the oil duct 2.The madial wall of casing 1 is provided with a plurality of fasteners 3.As shown in Figure 3, by fastener 3, magnetic screen 4 and insulation oil duct 2 are fixed on the sidewall of casing 1.
Magnetic screen 4 oil duct 2 that will insulate pushes against and is arranged on the casing 1, i.e. oil duct 2 clampings of will insulate of magnetic screen 4 and casing 1.Casing 1 and described magnetic screen 4 are close to mutually to guarantee that magnetic screen 4 can eliminate the stray loss in the casing 1.
In the present embodiment, magnetic screen 4 and casing 1 oil duct 2 clampings of will insulate jointly.Casing 1 is provided with grounding base 6, and described grounding base 6 is provided with the ground strip 5 that is electrically connected mutually with magnetic screen 4 so that magnetic screen 4 ground connection.
In the present embodiment, casing 1 is connected with insulation oil duct 2, and stream has cold oil in the insulation oil duct 2, and therefore, magnetic screen 4 can be by reducing the heat conduction to transformer-cabinet 1 to insulation oil duct 2.Owing to be insulated oil duct 2 between magnetic screen 4 and the casing 1 at interval, namely between the sidewall of the sidewall of casing 1 and magnetic screen 4, there is certain interval, make the heat of magnetic screen 4 can directly not conduct to casing 1, the part of casing 1 can not produce too high heat, and magnetic screen 4 simultaneously has better radiating effect.
Preferably, insulation oil duct 2 extends along the short transverse of casing 1 sidewall.Adopt this kind structure, fixedly more firm between insulation oil duct 2 and the magnetic screen 4.
The installation method of the fuel tank of this transformer, it may further comprise the steps:
A) casing 1 with fuel tank keeps flat, and casing 1 removing surface of fuel tank is clean;
C) magnetic screen 4 is placed on the insulation oil duct 2, and with fastener 3 magnetic screen 4 and insulation oil duct 2 is fixed on the casing 1;
D) ground strip 5 and magnetic screen 4 are electrically connected mutually.
The utility model adopts above structure, and the heat radiation of magnetic screen 4 is extended to the four sides from three heat radiations, and radiating effect is better, does not directly contact between casing 1 and the magnetic screen 4 simultaneously, and the heat of magnetic screen 4 generations can not be directly conducted to casing 1.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection range of the present utility model.
