Abstract
The utility model discloses a transformer oil tank. The transformer oil tank comprises an oil tank frame body. The oil tank frame body is formed by welding and connecting two side plates in a surrounding mode. Welding lines of the two side plates are arranged in an H-shaped groove seam on the lap joint position of the two side plates. Each side plate is composed of two layers, wherein a lower layer is a cold-roll steel sheet layer and an upper layer is an anti-oxidation layer. Compared with the prior art, welding strength between the side plates is improved, anti-oxidation can be achieved, and insulativity is better.
Description
Technical field
The utility model relates to a kind of oil tank of transformer.
Background technology
Existing oil tank of transformer encloses to connect with two plate-side plate weldings and forms, and every side plate two ends are the tack rectangle, and side plate is when being welded to connect, and some weld seam is positioned at the line of rabbet joint outside that overlap joint touches, thereby has reduced weld strength.
On the other hand, existing oil tank of transformer does not have anti-oxidation function, therefore easily corrosion.
Summary of the invention
For above-mentioned weak point, the purpose of this utility model just is to provide a kind of oil tank of transformer, and this oil tank of transformer has increased interpleural weld strength, and can also be anti-oxidation, and insulating properties is better.
The technical solution of the utility model is: a kind of oil tank of transformer, comprise the fuel tank framework, this fuel tank framework is enclosed to connect by two plate-side plate weldings and is formed, described two plate-side plate welding weld seams are arranged in the I-shaped line of rabbet joint of these two side plate lap-joints, described every block of side plate is comprised of two-layer, lower floor is the cold-rolled steel flaggy, and the upper strata is antioxidation coating.
As preferably, coat one deck bakelite flaggy on described fuel tank framework.
Compared with prior art; the beneficial effects of the utility model are: because the oil tank of transformer of the utility model protection all is trapezoidal due to side plate two ends; therefore the line of rabbet joint of biside plate lap-joint is I-shaped; increased the space that holds weld seam; weld seam can be filled in the line of rabbet joint fully, thereby increase interpleural weld strength.On the other hand, antioxidation coating makes the oil tank of transformer can corrosion.
Description of drawings
Fig. 1 is overall structure front view schematic diagram of the present utility model;
Fig. 2 is the utility model I partial enlarged drawing shown in Figure 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1-shown in Figure 2, a kind of oil tank of transformer comprises fuel tank framework 1, and this fuel tank framework is enclosed to connect by 2 welding of two blocks of side plates and formed, and two side plate 2 welded seam 3 are arranged in the I-shaped line of rabbet joint of these two side plate lap-joints.
Every block of side plate 2 is comprised of two-layer, and lower floor is cold-rolled steel flaggy 4, and the upper strata is antioxidation coating 5.Antioxidation coating 5 can be japanning.
Coat one deck bakelite flaggy 6 on fuel tank framework 1.Bakelite flaggy 6 makes the oil tank of transformer insulating properties better.
Above-mentioned execution mode is only as explanation of the present utility model and unrestricted; the utility model protection range also should comprise those apparent conversions to those skilled in the art, conversion, variation or substitute; and in the ken that those of ordinary skills possess, can also make various variations under the prerequisite that does not break away from this utility model aim.
Claims (2)
1. oil tank of transformer, comprise the fuel tank framework, this fuel tank framework is enclosed to connect by two plate-side plate weldings and is formed, it is characterized in that: described two plate-side plate welding weld seams are arranged in the I-shaped line of rabbet joint of these two side plate lap-joints, described every block of side plate is comprised of two-layer, lower floor is the cold-rolled steel flaggy, and the upper strata is antioxidation coating.
2. oil tank of transformer according to claim 1, is characterized in that: coat one deck bakelite flaggy on described fuel tank framework.
