Abstract
The invention discloses a transformer oil tank which comprises cooling oil, a tank body storing the cooling oil, a magnetic shield, clamps and an insulating oil passage. The clamps are used to clamp the magnetic shield to the tank body. The insulating oil passage is located between the tank body and the magnetic shield. The insulating passage is tightly abutted to the tank body through the magnetic shield, while a certain gap is reserved between the magnetic shield and the tank body. The tank body is provided with a ground seat, and the ground seat is provided with a ground plate electrically connected with the magnetic shield. The tank body closely neighbors to the magnetic shield with the insulating oil passage. Therefore, the oil passage is guaranteed to extend up along the height direction of the inner wall of the tank body. An installation method of a transformer cooler includes laying an oil tank, cleaning the surface of the oil tank, placing the insulating oil passage on the oil tank, placing the magnetic shield on the insulating oil passage, fixing the magnetic field to the insulating oil passage through the clamps, and electrically connecting the ground plate to the magnetic shield.

In the transformer running, when the leakage flux that winding produces is crossed casing, in casing, produce stray loss, cause simultaneously body partial overheated.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 only has three heat radiations, magnetic screen directly contacts with casing, the heat of magnetic screen directly conducts the heat accumulation that causes casing to casing.
Summary of the invention
For the problems referred to above, main purpose of the present invention 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 present invention takes 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 and the insulating oil duct between casing and magnetic screen on the casing, described magnetic screen is pushed against described insulating oil duct on the described casing, has certain interval between described magnetic screen and the described casing.
Preferably, be provided with grounding base on the described casing, be provided with the ground strip that is electrically connected mutually with magnetic screen on the described grounding base.
Preferably, described casing is close to mutually with described magnetic screen.
Preferably, described insulating oil duct is along extending on the madial wall short transverse of casing.
The invention also discloses a kind of installation method that adopts the fuel tank of transformer, it is characterized in that it may further comprise the steps:
A) casing with fuel tank keeps flat, and the tank surface of fuel tank is cleaned out;
B) insulating oil duct is placed on the casing;
C) magnetic screen is placed on the insulating oil duct, and with fastener magnetic screen and insulating oil duct is fixed on the casing;
D) ground strip and magnetic screen are electrically connected mutually.
The present invention adopts above structure and method, 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 invention is described in detail, thereby so that advantages and features of the invention can be easier to be those skilled in the art will recognize that protection scope of the present invention 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 simultaneously body partial overheated.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 invention discloses a kind of fuel tank of transformer, it comprises cold oil, the casing 1 of cold oil, insulating oil duct 2, magnetic screen 4 is housed.
Have cold oil in the casing 1, cold oil can certainly insulate and flow in the oil duct 2.Be provided with a plurality of fasteners 3 on the madial wall of casing 1.As shown in Figure 3, by fastener 3, magnetic screen 4 and insulating oil duct 2 are fixed on the sidewall of casing 1.
In the present embodiment, magnetic screen 4 clamps insulating oil duct 2 jointly with casing 1.Be provided with grounding base 6 on the casing 1, be provided with the ground strip 5 that is electrically connected mutually with magnetic screen 4 on the described grounding base 6 so that magnetic screen 4 ground connection.
In the present embodiment, casing 1 is connected with insulating oil duct 2, and stream has cold oil in the insulating oil duct 2, and therefore, magnetic screen 4 can be by reducing the heat conduction to transformer-cabinet 1 to insulating oil duct 2.Owing to be insulated oil duct 2 intervals between magnetic screen 4 and the casing 1, namely between the sidewall of the sidewall of casing 1 and magnetic screen 4, there is certain interval, so that 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 simultaneously magnetic screen 4 has better radiating effect.
Preferably, insulating oil duct 2 extends along the short transverse of casing 1 sidewall.Adopt this kind structure, fixing between insulating oil duct 2 and the magnetic screen 4 is more firm.
The invention also discloses a kind of installation method of fuel tank of 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;
B) insulating oil duct 2 is placed on the casing 1;
C) magnetic screen 4 is placed on the insulating oil duct 2, and with fastener 3 magnetic screen 4 and insulating oil duct 2 is fixed on the casing 1;
D) ground strip 5 and magnetic screen 4 are electrically connected mutually.
The present invention 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 invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
