Abstract
The utility model belongs to the technical field of transformers, and particularly relates to a transformer oil tank radiating circulating device which comprises a rectangular transformer oil tank and radiating fins. The oil tank is of a structure formed by welding four integral rectangular steel plates, so that the strength of the oil tank is enhanced. Angle steel is arranged at the edge of an original oil tank formed by welding steel plates, so that the welding stress of a whole tank body is optimized, and the lengths of welding lines are decreased. An oil way inlet and an oil way outlet are arranged on each rectangular steel plate, namely, holes are directly dug on the steel plates. Compared with an existing structure, the transformer oil tank radiating circulating device has the advantages that oil guide plates are welded on contact surfaces of the radiating fins and the wall of the oil tank, other positions are welded with the oil guide plates, more welding lines are formed, stress distribution is complicated, and oil ways among the oil guide plates are disordered in circulation. The transformer oil tank radiating circulating device is more reasonable and easy to machine, the oil ways are neatly distributed, and oil circulation radiating is facilitated.
Description
Technical field
The utility model belongs to the transformer technology field, is specifically related to a kind of heat radiation circulating device of oil tank of transformer.
Background technology
In general, transformer is in the process of electric energy transmitting, and its inner surface can produce loss.The loss that wherein produces because of the resistance of wire is relevant with load current, and is directly proportional to load current.This part loss has changed into heat energy basically, causes the Transformer Winding temperature to raise.Generally speaking the winding of transformer when particularly the low pressure winding moves due to transformer electric current maximum, so the heat energy that distributes is also maximum, temperature is the highest, and the insulating material of making transformer has the uniform temperature limit value, surpassed certain temperature limit, its insulating capacity can reduce greatly, affects the life-span of the safe operation of transformer.The rectangle fuel tank of existing transformer is by being welded between steel plate, and the middle part of board-like fin welding oil guide plate, makes the shunting of deep fat and cold oil.But the rectangle fuel tank of transformer utilizes steel plate to weld in the termination, and weld seam is larger, and in use poor sealing, at board-like fin middle part welding oil guide plate, make casing integrated stress skewness simultaneously, poor sealing, and difficulty of processing becomes large.
The utility model content
The utility model can provide a kind of good sealing effect, and Oiltank structure is more reasonable, the better oil tank of transformer heat radiation of radiating effect circulating device.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: oil tank of transformer heat radiation circulating device, comprise rectangle fuel tank and fin, the sidewall of described rectangle fuel tank is formed by four whole Plate Weldings, described fin is welded on whole steel plate, runs through the oil circuit import and the oil circuit outlet that are provided with fin on described whole steel plate.
Adopt technique scheme, in the utility model, the fuel tank sidewall is welded by four all-in-one-piece rectangular steel plates, compares with existing Oiltank structure: each face of existing fuel tank is integrally welded by plurality of steel plates, and weld seam is very long like this, and intensity is bad.After fuel tank is welded with four all-in-one-piece rectangular steel plates, strengthened the intensity of fuel tank.Be provided with oil circuit import and the oil circuit outlet of fin on rectangular steel plates, the through hole that directly digs exactly on steel plate.Compare with existing structure: in existing structure, weld oil guide plate on the contact-making surface of fin and oil tank wall, and other positions and oil guide plate welding, position while welding is many, and stress distribution is complicated, and the oil circulation between oil guide plate is more chaotic.And the scheme in the utility model is more reasonable, and easily processing, and oil circuit distributes more neat, is convenient to oily circulation cooling.
Further, four of described rectangle fuel tank seamed edge places are welded with angle steel.Fuel tank edges and corners at original Plate Welding are provided with angle steel, have optimized like this welding stress of whole casing, have reduced the length of weld seam.
Further, described angle steel is positioned at the inner surface of fuel tank corner angle, and oil molecule is to outdiffusion difficulty, better tightness.
Further, described oil circuit outlet is positioned at the lower end of oil circuit import, because the cold oil expanded by heating rises, cooling rear volume reduces to descend, oil circuit import simultaneously and oil circuit outlet must be avoided the weld seam of rectangular steel plates and fin, be positioned at the overlapping of rectangular steel plates and fin, so just can make the cold oil fin of flowing through, play the effect of heat radiation.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the plan structure schematic diagram of the utility model oil tank of transformer heat radiation circulating device;
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic diagram.
Embodiment
As shown in Figure 1, 2: the loop direction of the arrow logo cold oil on figure.Oil tank of transformer heat radiation circulating device, comprise transformer rectangle fuel tank 1 and fin 2, described fuel tank 1 is four all-in-one-piece rectangular steel plates Welding Structures, fit and weld angle steel 3 in the edges and corners of fuel tank 1, angle steel 3 is welded and fixed with the inner surface of fuel tank 1 corner angle, rectangular steel plates is provided with oil circuit import 5 and outlet 4, oil circuit outlet 4 is positioned at the lower end of oil circuit import 5, oil circuit outlet 4 is positioned at the lower end of fin 2 upper ends and rectangular steel plates weld, and oil circuit import 5 is positioned at the upper end of fin 2 lower ends and rectangular steel plates weld.
In the present embodiment, fuel tank 1 is four all-in-one-piece rectangular steel plates Welding Structures, and compare with existing fuel tank 1 structure: each face of existing fuel tank 1 is integrally welded by plurality of steel plates, and weld seam is very long like this, and intensity is bad.After four all-in-one-piece rectangular steel plates welding of fuel tank 1 use, strengthened the intensity of fuel tank 1.Simultaneously be provided with angle steel 3 in fuel tank 1 edges and corners of original Plate Welding, optimized like this welding stress of whole casing 1, reduced the length of weld seam.Being provided with oil circuit import 5 and oil circuit outlet 4 on rectangular steel plates, is exactly direct borehole on steel plate.Compare with existing structure: in existing structure, weld oil guide plate on the contact-making surface of fin 2 and fuel tank 1 wall, and other positions and oil guide plate welding, position while welding is many, and stress distribution is complicated, and the oil circulation between oil guide plate is more chaotic.And the scheme in the utility model is more reasonable, and easily processing, and oil circuit distributes more neat, is convenient to oily circulation cooling; Angle steel 3 is welded and fixed with the inner surface of fuel tank 1 corner angle, and oil molecule is to outdiffusion difficulty, better tightness; Oil circuit outlet 4 is positioned at the lower end of oil circuit import 5, and oil circuit outlet 4 is positioned at the lower end of oil circuit import 5, and oil circuit outlet 4 is positioned at the lower end of fin 2 upper ends and rectangular steel plates weld, and oil circuit import 5 is positioned at the upper end of fin 2 lower ends and rectangular steel plates weld.Because the cold oil expanded by heating rises, cooling rear volume reduces to descend, and oil circuit import 5 simultaneously and oil circuit outlet 4 must be avoided the weld seam of rectangular steel plates and fin 2, is positioned at the overlapping of rectangular steel plates and fin 2, so just can make the cold oil fin of flowing through, play the effect of heat radiation.
