Abstract

The utility model relates to an oil tank for transformers, which comprises an oil tank body. Oil is distributed in the oil tank body. The oil tank for transformers is characterized in that bell jar components are distributed on the periphery of the oil tank body. Simultaneously, a sealed structure is arranged between the bottom of each bell jar component and the periphery of the oil tank body, and no oil is available for circulation inside the bell jar components. Accordingly, sealing performance of a product is reliable for a long period of time without leakage and possibility of environmental pollution due to the sealed structures arranged among the bottoms of the bell jar components and the periphery of the oil tank body. Oil consumption is also reduced, and oil can be saved for about 7% to 10%. In addition, the oil tank for transformers can more effectively shield noise since the bell jar components are relatively independent, and the oil tank is applicable to large-sized power transformers and some special transformers.

Description

The transformer fuel tank

Technical field

The utility model relates to a kind of fuel tank, relates in particular to a kind of transformer fuel tank.

Background technology

In existing oil-filled transformer, tend to adopt the fuel tank of different shaping to satisfy user demand, but existing fuel tank often adopt the steel plate weldment to constitute various heat-dissipating structures.So easy seal degree that influences fuel tank self is easy to occur leakage of oil.And, between existing heat-dissipating structure and the fuel tank connectivity structure is arranged, occur easily that oil plant flows in the heat-dissipating structure and the consumption of the oil plant that increases.Because inevitable noise can appear in the circulation repeatedly of oil plant, influence the use of transformer simultaneously.

The utility model content

The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of transformer fuel tank is provided.

For realizing the purpose of this utility model transformer fuel tank, include the fuel tank body, be distributed with oil plant in the described fuel tank body, wherein: described fuel tank body periphery is distributed with the bell jar parts, between described bell jar feature bottom and the fuel tank body periphery is enclosed type construction, no oil plant circulation in the bell jar parts.

Further, above-mentioned transformer fuel tank, wherein, described bell jar parts are the flat roof type bell jar, the bell jar component top is provided with plate radiating plate.

Further, above-mentioned transformer fuel tank, wherein, the thickness of described plate radiating plate is 2～10mm.

Further, above-mentioned transformer fuel tank, wherein, the thickness of described plate radiating plate is 5mm.

Further, above-mentioned transformer fuel tank, wherein, described bell jar parts are trapezoidal top formula bell jar, the bell jar component top is provided with trapezoidal fin.

Further, above-mentioned transformer fuel tank, wherein, the thickness of described trapezoidal fin is 2～10mm.

Again further, above-mentioned transformer fuel tank, wherein, the thickness of described trapezoidal fin is 5mm.

Adopting technical solutions of the utility model, is enclosed type construction between bell jar feature bottom and the fuel tank body periphery, and no oil plant circulation is guaranteed product hermeticity reliably and with long-term in the bell jar parts, and ne-leakage does not pollute the environment.Simultaneously, also reduced expending of oil plant, fuel economy about 7%～10%.And because the bell jar parts are relatively independent, shielding noise can be applicable on large-scale power transformer and some special transformer preferably.

The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Description of drawings

Fig. 1 is the transformer fuel tank structure schematic diagram that adopts the flat roof type bell jar;

Fig. 2 is the transformer fuel tank structure schematic diagram that adopts trapezoidal top formula bell jar.

The implication of each Reference numeral is as follows among the figure:

1 fuel tank body, 2 bell jar parts

3 plate radiating plates, 4 trapezoidal fin

Embodiment

Transformer fuel tank as shown in Figure 1 and Figure 2, include fuel tank body 1, be distributed with oil plant in this fuel tank body 1, its special feature is: be distributed with bell jar parts 2 in fuel tank body 1 periphery, between bell jar parts 2 bottoms and fuel tank body 1 periphery is enclosed type construction, and no oil plant circulation in the bell jar parts 2.

In conjunction with the utility model one preferred implementation, the bell jar parts 2 of employing are the flat roof type bell jar, and bell jar parts 2 tops are provided with plate radiating plate 3, promptly as described in Figure 1.Specifically, in order better to realize radiating effect, the thickness of the plate radiating plate 3 that the utility model adopts is 2～10mm.And,, be that 5mm can reach preferable radiating effect to adopt thickness by finding after the multiple comparison test.

Certainly, consider transformer with the user demand of fuel tank, for better thus increasing heat radiation effect, the utility model can also have following execution mode: both as shown in Figure 2, the bell jar parts 2 that adopt are trapezoidal top formula bell jar, and bell jar parts 2 tops are provided with trapezoidal fin 4.And in order further to promote the radiating efficiency of trapezoidal fin 4, its thickness can be 2～10mm.Simultaneously, be that the trapezoidal fin 4 of 5mm has preferable performance in actual operation to adopt thickness.

By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, behind employing the utility model, be enclosed type construction between bell jar feature bottom and the fuel tank body periphery, no oil plant circulation in the bell jar parts, guarantee product hermeticity reliably and with long-term, ne-leakage does not pollute the environment.Simultaneously, also reduced expending of oil plant, fuel economy about 7%～10%.And because the bell jar parts are relatively independent, shielding noise can be applicable on large-scale power transformer and some special transformer preferably.

Certainly, more than only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
