Abstract
The invention discloses an oil tank structure of an oil-immersed transformer. The oil tank structure comprises an upper flange, a corrugated radiating fin, a box bottom, an arc-shaped plate, supports and an oil outlet nozzle, wherein connection corners of a box body have rounded-corner rectangular box body structures. The oil tank structure has the beneficial effects that both the upper flange and the box bottom are molded by stamping at a time, and the oil tank is in rounded-corner transition, so that oil in an oil tank can flow circularly better, and heat dissipation and cooling of the transformer are facilitated. The corrugated radiating fin is encircled as a whole, and radiating fins are arranged additionally on transition rounded corners on four sides, so that the welding workload is lowered; the heat dissipation rea is increased; the heat dissipation efficiency is increased; and the service life of the transformer is prolonged. The arc-shaped plate is circular-arc-shaped, so that the inner space of the oil tank is not occupied, and mounting and placement of other devices are facilitated. The bottom is in rounded-corner transition, and the oil outlet nozzle is arranged on a bottom surface of the box bottom, so that complete discharge of insulating oil and residues is facilitated; the overhauling workload is reduced; and the running safety of the transformer is ensured. The oil tank structure has a simple structure and high reliability; the production efficiency is increased; and the product quality is improved.

Technical field
The invention belongs to a kind of oil immersion-type distribution transformer, especially relate to the Oiltank structure of a kind of oil immersion-type distribution transformer.
Background technology
The Oiltank structure of existing oil immersion-type distribution transformer by oil outlet, feet, bottom, corrugate fin, onPortion's methodOrchid is welded to form, and casing is rectangular box structure；OnPortion's methodOrchid angle steel and round steel are welded to form, and bottom steel plate and angle steel are welded to form, and corrugate fin divides four to be welded onPortion's methodBetween orchid and bottom, fin is at a right angle with fin to be connected, and eight angles of bottom are right angle, onPortion's methodBlue four angles are right angle, and in casing corner, bosom bar strengthens bottom and upperPortion's methodBlue connection；Oil outlet is arranged on bottom side.
This Oiltank structure there is the problem that due to the large-area welding that fuel tank is overall, easily be deformed, the weld defect such as rosin joint, and when being processed by shot blasting after welding, easily produce crack, thus cause the phenomenons such as fuel tank leakage of oil, permeability, when operating transformator leakage of oil, permeability phenomenon occur, existence due to oil, can not carry out repeating welding, thus bring potential safety hazard to product, add difficulty to product reparation；Fuel tank integral heat sink area is few, affects the radiating effect of transformer oil；Due to the right-angle structure of box bottom, and oil outlet is arranged on the most difficult removing of bottom side, insulating oil and residue totally, brings hidden danger to the safe operation of transformator；Complex procedures, the time-consuming material that takes during making, and globality is poor, unsightly, reduces production efficiency, have impact on the quality of product.
Summary of the invention
It is an object of the invention to overcome shortcoming present in prior art, it is provided that a kind of radiating efficiency is high, be conducive to oil body at fuel tank internal circulation flow, easily cleaning, simple in construction, the oil immersion-type distribution transformer fuel tank of good reliability.
To achieve these goals, the technical solution used in the present invention is as follows: a kind of oil immersion-type distribution transformer Oiltank structure, including: onPortion's methodOrchid, corrugate fin, bottom, arc, feet, oil outlet, the joint angle of casing is the rectangular box structure of fillet；
Further, described upperPortion's methodOrchid, is shaped as the rectangle framework of longitudinal section rectangular shape " 7 " font；
Further, onPortion's methodBlue joint angle is fillet；
Further, described bottom, it is shaped as channel-shaped body with the end；
Further, bottom joint angle is fillet；
Further, onPortion's methodBlue and bottom is punching press one-shot forming；
Further, corrugate fin is that whole piece is around being welded onPortion's methodBetween orchid and bottom；
Further, casing four fillet liner arc reinforcing plate increases casing intensity；
Further, oil outlet is arranged on bottom bottom surface.
The invention has the beneficial effects as follows: oil immersion-type distribution transformer Oiltank structure of the present invention, onPortion's methodBlue and bottom is punching press one-shot forming, production efficiency height, compact conformation, appearance looks elegant；Junction, fuel tank four limit and bottom junctions all use round-corner transition, can promote that oil body preferably circulates in fuel tank, beneficially the radiating and cooling of transformator；The cincture of corrugate fin full wafer also sets up fin at four limits connection knuckles, decreases welding job amount, adds area of dissipation, improve radiating efficiency, extends the service life of transformator.Arc reinforcing plate is done and in the arc-shaped is not take up space in fuel tank, is conducive to the installation of other device to place.It is clean that bottom junctions uses round-corner transition, oil outlet to be arranged on the eliminating of bottom bottom surface, beneficially insulating oil and residue, reduces maintenance workload, it is ensured that transformator runs safety.The oil tank of transformer of this structure is the most easy to make, save time province's material, increases the connection of circular arc, and overall appearance is beautiful, the advantage with simple in construction, good reliability.Improve production efficiency, improve the quality of product.
