Abstract
The utility model adopts an oil tank for immersed power transformers, which comprises a tank edge, a tank wall and a tank bottom, wherein the tank wall consists of a front wall, a rear wall and two sidewalls, the four walls define a square, the tank wall is vertically arranged on the tank bottom, the upper end of the tank wall is connected with the tank edge, the lower ends of the front wall and the rear wall of the tank wall are vertically and inwardly bent to form an upper flange, and the end of the upper flange is vertically and downwardly bent to form an inner flange, which is connected with the tank bottom. Since the bottom of the tank wall is inwardly bent below the position of a coil and then welded on the tank bottom, the dimension of the lower part of the oil tank can be reduced, the oil consumption of a transformer is reduced, and the cost is saved.
Description
Technical field
The utility model relates to a kind of fuel tank of oil-immersed power transformer.
Background technology
The tank wall width of present power transformer fuel tank all is identical width from the top to the bottom, because generally all there is a segment distance position of coil setting at the bottom of apart from case, the big gauging of fuel tank bottom is not brought into play great insulating effect, shines into unnecessary waste.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of fuel tank of saving transformer with the oil-immersed power transformer of oil mass is provided.
For achieving the above object, the utility model adopts a kind of fuel tank of oil-immersed power transformer, comprise at the bottom of case edge, tank wall, the case, tank wall comprises front face, rear surface and two side wall surfaces, and four walls surround hollow, on tank wall uprightly is arranged at the bottom of the case, tank wall upper end and case are along splicing, the front face of tank wall forms upper hem with all vertical inwardly bending in rear surface lower end, and the bending vertically downward of upper hem end forms interior flanging, on interior flanging is connected at the bottom of the case.
On the beneficial effects of the utility model were tank wall bottoms at the bottom of inwardly being welded on case after the bending below the coil position, the lower dimension that can dwindle fuel tank reduced the transformer oil mass, the saving cost.
The utility model is further defined to described fuel tank and comprises stiffener, and described stiffener vertically is arranged in the groove that forms at the bottom of tank wall upper hem, interior flanging and the case.Stiffener can improve fuel tank intensity.
