Abstract
The utility model relates to a transformer oil tank. A cross section of a tank body wall of the oil tank is wave-shaped, and the wave shape is formed by connecting each section of arcs sequentially. The transformer oil tank saves the welding working hours and the cost, reduces the labor intensity and dead weight of the tank body, and has simple structure; by means of the wave-shaped tank body wall, on one hand, the intensity of the tank body wall is enhanced, on the other hand, the surficial area of the tank body wall is increased, the heat dissipation efficiency is improved, and the use of cooling fins is saved; and simultaneously, the wave-shaped tank body wall further reduces the noise generated by the transformer during working.
Description
Technical field
The utility model relates to a kind of oil tank of transformer.
Background technology
For a long time, the fuel tank body wall of high-power transformer adopts light sheet material to process, in order to improve the intensity of box body wall, and usually can be at some of the outside weldings of box body wall reinforcement or rib longitudinally.When carrying out welding processing, often take time and effort, and, the welding position might be by burn-through, even burn-through not, the box body wall intensity through welding also has been subject to impact so, in use procedure in the future, if welding position generation leakage of oil owing to being reinforced muscle or rib blocks, can be difficult to repair.And, at box body wall surface soldered reinforcement or rib, also affect attractive in appearancely, increased simultaneously the deadweight of tank body of oil tank, increased cost.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to the reality needs, and a kind of oil tank of transformer is provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of oil tank of transformer, the cross section undulate of fuel tank body wall.
Described waveform is connected in sequence by each section circular arc.
The beneficial effects of the utility model are:
1. when having saved the Welder, reduce labour intensity, reduced the casing deadweight, simple in structure, save cost;
2. corrugated box body wall has strengthened the intensity of box body wall on the one hand, on the other hand, has increased the surface area of box body wall, has improved radiating efficiency, has saved the use of fin;
3. the noise when simultaneously, corrugated box body wall has also reduced transformer work.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: referring to Fig. 1.
A kind of oil tank of transformer, the cross section undulate of fuel tank body wall 1.
Described waveform is connected in sequence by each section circular arc.
Corrugated box body wall 1 can by bender and corrugation mould coordinate with steel plate successively bending form.
Only show the part relevant to inventive point of the present utility model in figure, remainder is all not shown.
When the utility model has been saved the Welder, reduce labour intensity, reduced the casing deadweight, simple in structure, save cost; Corrugated box body wall, one side has strengthened the intensity of box body wall, on the other hand, has increased the surface area of box body wall, has improved radiating efficiency, has saved the use of fin; Noise when simultaneously, corrugated box body wall has also reduced transformer work.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection range of the present utility model.
Claims (1)
1. oil tank of transformer, the cross section undulate of fuel tank body wall is characterized in that: described waveform is connected in sequence by each section circular arc.
