Abstract
The utility model discloses a transformer oil tank, which comprises an oil tank body. The transformer oil tank is characterized in that the oil tank body adopts a bell jar-type structure; a plurality of convex ripples in parallel layout are formed on a tank wall of the oil tank body; the tank wall is formed in a corrugated manner at one time; pipe orifices are formed on the ripples; and flanges are arranged at the outer parts of the pipe orifices. The transformer oil tank has the advantages of simple and light structure, aesthetic appearance, high mechanical strength, good heat radiation performance and good noise reduction effect, and is convenient to manufacture and maintain.
Description
Technical field
The utility model relates to a kind of oil tank of transformer, particularly relates to a kind of bell type tank that adopts a corrugation moulding of large-scale folder.
Background technology
Development and lifting along with transformer technology; Various big capacity high voltage transformers are designed and develop; And each item technical parameter of transformer also constantly increases; This type of novel transformer is increasingly high to the functional requirement of fuel tank each item, therefore needs a kind of novel oil tank of transformer to satisfy its needs.
Traditional oil tank of transformer is through the welding of a large amount of reinforcement iron and stiffener is processed to improve its mechanical strength, and the manufacturing of its structure requires lower, but shortcoming also clearly; At first strengthen iron and weld time-consuming expense material, the corner angle that stay, weld seam and welding slag are unfavorable for adhering to of surface paint, and complex structure is not attractive in appearance yet; As strengthen occurring under the iron seepage and be difficult for discovering, maintenance is difficulty also, along with the continuous increase of fuel tank specification; Its design, manufacturing and maintenance difficulty are also increasing, and the self-radiating effect is also poor, need install auxiliary radiating device additional; Its complex structure degree further promotes, and the weight of fuel tank and size can not be well controlled, and the assembling transportation is difficult for.
The utility model content
The utility model technical problem to be solved is the deficiency that overcomes prior art, provides a kind of simple and light, good looking appearance, and mechanical strength is high, perfect heat-dissipating, excellent noise reduction effect and be convenient to the corrugated oil tank of transformer making, keep in repair.
For solving the problems of the technologies described above; The utility model provides a kind of oil tank of transformer, comprises casing, it is characterized in that: said casing is the bell-jar structure; The tank wall of said casing is provided with the corrugation of a plurality of evaginations that are parallel to each other; Said tank wall is a corrugation moulding, offers the mouth of pipe on the said corrugation, and said mouth of pipe outside is provided with flange.Said bell-jar casing has the tank wall of a corrugation moulding, has cancelled reinforcement iron and stiffener, good looking appearance; Simple and light, reduced weld seam simultaneously, improved the mechanical strength of fuel tank; Enlarged the area of dissipation of casing, improved radiating effect, corrugation shape tank wall has effect weakening; Can reduce noise, be convenient to make, keep in repair.
Aforesaid oil tank of transformer is characterized in that: said flange is provided with notching construction and position limiting structure, and the junction of the said flange and the mouth of pipe is provided with the acrylonitrile-butadiene rubber sealing gasket.The flange that is provided with notching construction and position limiting structure is installed more firm, and acrylonitrile-butadiene rubber sealing gasket oil resistant, weather, anti-ozone further prevent the seepage of transformer.
The beneficial effect that the utility model reached:
Simple and light, good looking appearance, mechanical strength is high, perfect heat-dissipating, excellent noise reduction effect and be convenient to make, maintenance.
Description of drawings
Fig. 1 is the plan structure sketch map of the utility model;
Fig. 2 is the tank wall structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in 2; Fuel tank casing 1 is a bell-jar, and tank wall is provided with the corrugation 2 of a plurality of evaginations that are parallel to each other, and said tank wall is a corrugation moulding; Corrugation 2 top and bottom on two relative long end faces respectively are provided with a mouth of pipe 3; Each mouth of pipe 3 outside is equipped with flange 4, and flange 4 has notching construction and position limiting structure, and the mouth of pipe 3 is provided with acrylonitrile-butadiene rubber sealing gasket (not shown) with flange 4 junctions.
The tank wall of a corrugation moulding is processed by large-scale folder, has cancelled the use of strengthening iron, reinforcement or stiffener, and is simple and light, reduced weld seam; When having saved the Welder, also be more conducive to the coating of painting, also easier for repair of leakage; The corrugation of evagination has increased the area of dissipation of fuel tank casing, has improved radiating effect, and the tank wall of a corrugation moulding simultaneously has effect weakening; Can play the effect of noise reduction noise abatement, casing is carried out whole shot-peening, remove the wedge angle burr and the welding slag that produce in casing and the processing; Improve the adhesive force of paint, make presentation quality not only attractive in appearance but also lasting, flange surface is all carried out fine finishining; And be provided with fluting and position limiting structure, and adopt oil resistant, weather, ozone proof acrylonitrile-butadiene rubber sealing gasket simultaneously, prevented the seepage of transformer.
The utility model is simple and light, good looking appearance, mechanical strength is high, perfect heat-dissipating, excellent noise reduction effect and be convenient to make, maintenance.
Above embodiment limits the utility model never in any form, every above embodiment is made with the equivalent transformation mode other improve and use, all belong to the protection range of the utility model.
