Abstract
The utility model provides an oil tank of an oil-immersed transformer, which comprises an oil tank composed of a main frame, a tank cover and a supporting base, wherein fin type radiators are fixedly mounted on the outer surface on the two sides of the main frame, and further comprises auxiliary frames welded on two sides of the main frame, wherein two side wings of the auxiliary frames extend reversely out of the main frame, and the fin type radiators are fixedly mounted on the outer surface of each of the auxiliary frames. After the technical scheme is used, the biggest advantage of the oil tank of the oil-immersed transformer lies in that the radiator number is increased by one third compared with traditional oil tank structure of radiators on the basis of provided contour dimension and by adding the auxiliary frames, radiating surface of the oil tank is effectively improved, and radiating capability of the oil tank reaches the requirement of normal full load operation of the radiator.
Description
Technical field
The utility model relates to the technical field of power equipment, refers in particular to a kind of oil tank for oil immersion type transformer.
Background technology
Along with country's reform and opening-up; Greatly develop economic construction, improve the foreign exchange income, transformer industry also wins many foreign customer orders; Some of them National Environmental temperature reaches as high as 55 ℃; Distribution transformer is installed on the pillar or between little tunnel, Shan, this has just had predetermined restricted to the overall dimension of transformer, and the radiating effect of transformer will reach standard-required.At present traditional oil tank of transformer by main frame, be welded on corrugated plate (or being installed in the gilled radiator on the main frame) on the main frame, cover case lid on main frame, and base for supporting form.Because overall dimension is restricted and very high ambient temperature, adopt the corrugated tank of traditional structure just to satisfy not the heat radiation requirement.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of reasonable in design reliable, the oil tank for oil immersion type transformer of excellent in heat dissipation effect.
For realizing above-mentioned purpose, the technical scheme that the utility model provided is: a kind of oil tank for oil immersion type transformer, and it includes the fuel tank body of being made up of main frame, case lid, base for supporting; Wherein, Be installed with the ripple gilled radiator on two side external surfaces of described main frame, it also includes the secondary framework that is welded on the main frame both sides, wherein; Two flanks of described secondary framework oppositely extend main frame, and all are installed with corrugated-fin radiator on the lateral surface of each secondary framework.
The length that two flanks of described secondary framework extend is no more than the length of the ripple gilled radiator on the main frame.
The utility model is after having adopted such scheme; Its great advantage is that the utility model is under the situation of regulation overall dimension; Make fin count increase nearly 1/3 through the secondary framework of setting up than traditional transformer oil tank structure; Thereby improved the radiating surface of fuel tank effectively, made the heat-sinking capability of fuel tank reach the requirement that the transformer normal full load moves.

Fig. 3 is the vertical view of the utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
Shown in accompanying drawing 1 to accompanying drawing 3; The described oil tank for oil immersion type transformer of present embodiment, the secondary framework 6 that it includes the fuel tank body of being made up of main frame 1, case lid 2, base for supporting 34 and is welded on these main frame 1 both sides, wherein; Be welded with ripple gilled radiator 5 on two side external surfaces of described main frame 1; Simultaneously all be welded with ripple gilled radiator 7 on the lateral surface of each secondary framework 6, and two flanks of above-mentioned secondary framework 6 oppositely extend main frame 1, but in order to satisfy the overall dimension requirement of this oil tank of transformer; The length that two flanks of the described secondary framework 6 of present embodiment extend is no more than the length of the ripple gilled radiator 5 on the main frame 1; Therefore, present embodiment can not increase the overall dimension of oil tank of transformer, satisfies installation requirement; In addition; Two flanks through secondary framework 6 extend; The sheet number of feasible welding ripple gilled radiator 7 above that increases widely; Increase than traditional transformer oil tank structure nearly 1/3, thereby increased the radiating surface of fuel tank body 4 effectively, make the heat-sinking capability of the utility model reach the requirement of transformer normal full load operation.In a word, the utility model simple in structure, economical rationality, aesthetic in appearance, be a kind of very economical and practical product, be worthy to be popularized.
The examples of implementation of the above are the preferred embodiment of the utility model only, are not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection range of the utility model.
