Abstract
The invention discloses an oil tank of a large-size oil immersed type transformer. The oil tank comprises an oil tank body which is composed of four tank walls, and cross sections of the four side walls of the oil tank body are all configured to a continuous U-shaped structure. The oil tank walls are formed by welding continuously bent U-shaped steel plates. According to the oil tank provided by the invention, the strength of the oil tank can be improved, and the oil tank has the characteristics of simple processing way, small welding amount, capability of saving steel material and labor cost and the like; meanwhile, the surface area of the oil tank is increased, the heat radiation efficiency is improved and the use of heat radiation sheets is saved. Compared with the structure of the traditional transformer oil tank, the oil tank disclosed by the invention has the advantages that: the volume is reduced by about 15%, the cost is saved by about 18% and the economic benefit is obvious; meanwhile, the occupied area and the resource wastes are reduced and the shape of the oil tank is more smooth and attractive, so that the oil tank accords with current low-carbon, green and environment-friendly concepts.
Description
Technical field
The present invention relates to a kind of large oil immersed formula oil tank of transformer, especially, belong to the transformer technology field at 110kv and above power transformer fuel tank.
Background technology
High-power transformer device body is very heavy, and the volume of fuel tank is very big, on base, will place tens tons, even the device body of up to a hundred tons of weights, can reach hundreds of tons sometimes together with the weight of transformer oil and fuel tank itself thereof and corresponding annex.In transit, fuel tank is exactly transformer " packing case ".The high voltage large capcity transformer requires vacuum oil, in the maintenance, requires again to utilize the airtight pressure vessel of fuel tank to carry out the dried of device body at the scene, therefore, the mechanical strength of high-power transformer fuel tank is had very strict requirement.If still adopt the box lid type structure, heart maintenance is hung at the scene of being difficult in.Therefore, when capacity increases to certain limit, just should not adopt the box lid type Oiltank structure again, and adopt the bell type tank structure.Adopt the transformer of bell type tank, only need hang out bell jar device body and just come out.Because bell-jar shell weight is limited, so the scene just has ready conditions and hangs cover, and the device body is done maintenance fully.It is fuel tank that general 110kV and above large oil immersed power transformer adopt bell jar more.
At present, the bell-jar structure of most large oil immersed power transformer, the Oiltank structure of employing is: the fuel tank of weldering reinforcement.(1 is fuel tank, and 2 is reinforcement) as shown in Figure 1.It is the reinforcement anyhow of burn-oning in the oil tank wall outside, constitutes a skeleton in the oil tank wall outside, and this skeleton is divided into several zonules with oil tank wall, to improve the intensity of oil tank wall.The form of this layout makes processing become comparatively complicated, and performance is not very good, and outward appearance is attractive in appearance inadequately, therefore is eliminated gradually.
Summary of the invention
To the deficiency that prior art exists, technical problem to be solved by this invention is to provide a kind of perfect heat-dissipating, raising oil tank wall intensity, increase gas tank gage area, the simple large oil immersed power transformer of processing mode to use fuel tank.
For solving the problems of the technologies described above, the technical scheme that the present invention taked is: a kind of large oil immersed formula oil tank of transformer, comprise the fuel tank body of forming by four sidewalls, and the cross section of four sidewalls of said composition fuel tank body all is set to continuous U type structure.
Above-mentioned large oil immersed formula oil tank of transformer, said its U type mouth of each U type structure is all towards the fuel tank inner chamber.
Above-mentioned large oil immersed formula oil tank of transformer, said continuous U type structure are set to a plurality of U shaped steel plates and are welded to one another and form.
The advantage of the large oil immersed formula oil tank of transformer of the present invention is: oil tank wall adopts the U shaped steel plate of bending continuously to be welded; This invention can improve the intensity of fuel tank, and it is simple to have a processing mode, and welding capacity is little, can save characteristics such as steel and cost of labor; Simultaneously, increase the surface area of fuel tank, improved radiating efficiency, saved the use of fin.Relative traditional transformer Oiltank structure, volume has reduced about 15%, cost savings about 18%, remarkable in economical benefits.Simultaneously, reduced the floor space and the wasting of resources, profile is also smooth, attractive in appearance more, meets the theory of present low-carbon (LC), green, environmental protection.
Description of drawings
Fig. 1 is traditional transformer oil tank structure sketch map;
Fig. 2 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details;
As shown in Figure 1, be traditional transformer oil tank structure figure;
As shown in Figure 2, a kind of large oil immersed formula oil tank of transformer comprises the fuel tank body of being made up of front side wall 1, rear wall 2, left side wall 3,4 four sidewalls of right side wall 5, and the cross section of forming four sidewalls of fuel tank body 5 all is set to continuous U type structure 6.Continuous U type structure 6 is set to a plurality of U shaped steel plates and is welded to one another and forms.For improving heat dispersion, each U type structure 6 is set to its U type mouth 61 all towards fuel tank inner chamber 51.
Add man-hour,, select the steel plate of suitable thickness at first according to the size of transformer capacity; On hydraulic press, roll over steel plate with special-purpose bending mould Curved Continuous; Be processed into the U type of setting, the spacing between bending plate U type is curved can be selected according to the flexible in size of transformer capacity.After the tank wall bending is accomplished, be stitched together through electric welding.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; Those skilled in the art; In essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
