Abstract
The invention relates to a large power transformer oil tank structure applicable to railway bridge type integral transportation, and belongs to the technical field of transformer production devices. The technical scheme is that lower ends of a first oil tank wall (2) and a second oil tank wall (3) on two sides of the transformer oil tank are respectively welded with the oil tank bottom (6) into a whole through a first iron reinforcer (4) and a second iron reinforcer (5), an included angle is formed between each of the first and second iron reinforcers and the oil tank bottom, distance between the first oil tank wall (2) and the second oil tank wall (3) is more than the width of the oil tank bottom, a hanger shaft (7) is arranged at the upper end of each of the first oil tank wall (2) and the second oil tank wall (3) on two sides of the transformer oil tank, a hanger shaft baffle plate (8) is welded to the outer side of each hanger shaft, and the oil tank cover (1) is trapezoidal in cross section. By using the large power transformer oil tank structure, the problem that the traditional oil tank is large in volume and insufficient in strength during a railway bridge type integral transportation process is basically solved; and the large power transformer oil tank structure has the advantages of being simple in structure, saving in material, small in volume, and high in structural strength.
Description
Technical field
The present invention relates to a kind of large-scale power transformer Oiltank structure, especially the large-scale power transformer Oiltank structure of railway bridge-type whole Transporting, belong to transformer making apparatus technical field.
Background technology
In large-scale power transformer, because transformer capacity is comparatively large, therefore, the overall dimensions of fuel tank are comparatively large, thus cause the transport of transformer very difficult.This kind of large-scale power transformer adopts highway transportation, be subject to bridge, tunnel constraint a lot.Adopt railway transportation, also will meet the requirement on railway fortune circle, and bridge-type transports the increase of the fuel tank intensity also can brought, thus increase manufacturing cost.
Summary of the invention
The object of the invention is to provide a kind of large-scale power transformer Oiltank structure being applicable to railway bridge-type whole Transporting, can meet the requirement on railway fortune circle, and the requirement of strength of fuel tank, solves Problems existing in background technology.
Technical scheme of the present invention is:
A kind of large-scale power transformer Oiltank structure being applicable to railway bridge-type whole Transporting, comprise fuel tank case lid, the fuel tank tank wall one of oil tank of transformer both sides and fuel tank tank wall two, strengthen iron one, strengthen iron two, at the bottom of fuel tank, hanging axis and hanging axis baffle plate, the fuel tank tank wall one of oil tank of transformer both sides and the lower end of fuel tank tank wall two are connected into integrative-structure respectively by reinforcement iron one and reinforcement iron two with fuel tank back welding, strengthen iron one and strengthen iron two being provided with angle with at the bottom of fuel tank, be arranged symmetrically with, distance between fuel tank tank wall one and fuel tank tank wall two is greater than the width at the bottom of fuel tank, the fuel tank tank wall one of oil tank of transformer both sides and the upper end of fuel tank tank wall two are respectively equipped with hanging axis, hanging axis baffle plate is welded outside hanging axis, fuel tank case lid cross section is trapezoidal.
The fuel tank tank wall one of described oil tank of transformer both sides and fuel tank tank wall two are that grooved is welded by steel plate bending respectively.
The diameter of described hanging axis is less than the height of hanging axis baffle plate outside hanging axis.
The invention has the beneficial effects as follows: fundamentally solve traditional fuel tank volume in railway bridge-type whole Transporting process comparatively large, the problem of insufficient strength, have structure simple, economize in raw materials, volume is little, fuel tank overall construction intensity advantages of higher.
