Abstract

The utility model discloses a transformer oil tank, in particular to a transformer oil tank with flutes, which is structurally characterized in that a plurality of unidirectional outwards convex flutes are in interval and parallel arrangement on the wall of the tank body. The utility model has the advantages of simple structure, low manufacturing cost, high strength and the like.

Description

A kind of oil tank of transformer

Technical field

The utility model relates to a kind of oil tank of transformer, specifically is meant a kind of oil tank of transformer with corrugation.

Background technology

For a long time, the fuel tank of high-power transformer all adopts thin material to process, in order to carry a large amount of cold oils in the fuel tank, need adopt at the outer wall of fuel tank with dull and stereotyped weldering reinforcing rib structure, this structure is lower to making requirement, realizes easily, but has following shortcoming:

1. structure is more outmoded, and the outward appearance corner angle add weld seam, and is not attractive in appearance;

2. take more when strengthening the iron Welder;

3. if be reinforced the zone generation oil impregnate that iron hides, extremely difficult the reparation;

4. for big capacity self-cooled transformer, all radiators can't be directly installed on the tank wall, need to make large-scale cooling connection guard system, again radiator is installed on the cooling connection guard system, cause the consumption in material and man-hour;

5. because cooling joins the existence of guard system, increased the weight and the width dimensions of transformer;

6. owing to strengthen the existence of iron and special use cooling connection guard system in a large number, increased the complexity of transformer device structure, brought certain difficulty to design, manufacturing, maintenance.

The utility model content

The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and a kind of simple in structure, production cost is low, intensity is high corrugated oil tank of transformer is provided.

For achieving the above object, the technical solution of the utility model is that spaced and parallel is provided with the corrugation of many unidirectional evaginations on the tank wall of described casing.

The corrugation that further setting is described unidirectional evagination is connected to form by five sections arcwall faces.

Advantage of the present utility model is: appearance of oil tank is attractive in appearance; Do not need on tank wall, to weld again a large amount of reinforcements, reduce the fuel tank welding deformation; Cancelled tank wall and strengthened iron, when having saved the Welder; There is not covered weld seam in the tank wall surface, and seepage reparation property is good; Cancel special-purpose cooling connection guard system, made the product simplicity, made things convenient for design, manufacturing, maintenance; Part and bulk strength are better, all radiators all can be directly installed on the tank wall, do not need to make separately cooling connection guard system, material and man-hour have been saved in a large number, for the 110kV self cooled transformer, it is in light weight nearly 1 ton, width takes up an area of size and has reduced by 1000～1200mm, and the corrugation tank wall has effect weakening, the noise when reducing transformer work.

Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.

Embodiment

Embodiment of the present utility model as shown in Figure 1, include casing 1, spaced and parallel is provided with the corrugation 2 of many unidirectional evaginations on the tank wall of described casing, add man-hour, on large-sized bender, special-purpose corrugation mould is installed, steel plate is placed in the bender, fold the corrugation shape one by one, then corrugation tank wall and other part are welded into fuel tank.The corrugation 2 of the unidirectional evagination of the described corrugation of present embodiment plays the effect of reinforcement, does not therefore need to weld on tank wall a large amount of reinforcements again, reduces the fuel tank welding deformation; Cancelled tank wall and strengthened iron, when having saved the Welder; There is not covered weld seam in the tank wall surface, and seepage reparation property is good.

The corrugation of the described unidirectional evagination of present embodiment is as shown in Figure 2 connected to form by multistage arcwall face 3 in addition, makes that the intensity of corrugation is better.

Claims

1. an oil tank of transformer includes casing, it is characterized in that: spaced and parallel is provided with the corrugation of many unidirectional evaginations on the tank wall of described casing.

2. a kind of oil tank of transformer according to claim 1 is characterized in that: the corrugation of described unidirectional evagination is connected to form by the multistage arcwall face.
