Problems solved by technology

[0002] The transformer oil tanks in the prior art are all made of steel. This kind of oil tank not only has a relatively large weight, but also has an unsatisfactory heat dissipation effect. Some technicians in the industry consider using aluminum as the only material for the oil tank. However, during the production process, Since the material of aluminum itself is relatively soft and has a low melting point, there is no suitable method to produce an aluminum alloy fuel tank with a stable structure and small installation errors

Embodiment Construction

[0016] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0017] A method for manufacturing an aluminum transformer oil tank, comprising the following steps:

[0018] 1) Material selection: GB / T3880 type aluminum plate is used to remove the oxide film on the surface of the aluminum plate; the selection of GB / T3880 type aluminum plate is mainly based on the content of magnesium and silicon to ensure the welding performance of the aluminum plate.

[0019] 2) Allowance setting: According to the thickness of the aluminum plate, set the allowance for the aluminum plate to be processed. When the length of the aluminum plate is 2m and the thickness is greater than or equal to 8mm and less than 12mm, set a margin of 10mm on ...

Abstract

The invention relates to a manufacturing method of an oil tank of an aluminum transformer. The method comprises the steps as follows: material selection, allowance set, processing of oil tank, set of reinforcing rib, assembly of oil tank wall, flange processing and set of tank cover. According to the manufacturing method of the oil tank of the aluminum transformer, aluminum plates are processed and spliced to an aluminum alloy tank, and the technical difficult problems that an aluminum material is soft in texture and low in melting point by bending aluminum plates by virtue of a method of bending the aluminum plates to be vertical to an extending direction.

Description

technical field [0001] The invention relates to a manufacturing method of an aluminum transformer oil tank. Background technique [0002] The transformer oil tanks in the prior art are all made of steel. This kind of oil tank not only has a relatively large weight, but also has an unsatisfactory heat dissipation effect. Some technicians in the industry consider using aluminum as the only material for the oil tank. However, during the production process, Since the material of the aluminum itself is relatively soft and has a low melting point, there is no suitable method to produce an aluminum alloy fuel tank with a stable structure and small installation errors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for manufacturing an aluminum transformer oil tank in order to overcome the disadvantages of high processing requirements and easy leakage at joints in the prior art. [0004] The technical solution...
