Abstract
The utility model relates to a tank shell for a large transformer, in particular to a tank shell with reinforcing ribs for the large transformer. The tank shell comprises a body, the reinforcing ribs are distributed on the outer side walls of the periphery of the body and are rectangular cavities, and the cavities are fixed in the outer side wall of the body. Yellow sand is filled with the cavities, the distance between two sides, parallel to the outer side wall of the body, of the cavities ranges from 10cm to 20cm, and the walls of the cavities are 6-9mm in thickness. The distance between the two adjacent cavities is 40-80cm. The cavities are welded and fixed on the side walls of the periphery of the body. Filling rate of the yellow sand in the cavities is 95%, and the yellow sand is dry fine sand 1-1.5mm in particle size. The tank shell for the large transformer is capable of effectively reducing noise of the transformer and damping the noise by the yellow sand when the noise is transmitted from the inside to the outside. Besides, strength of the transformer is improved and service life of the transformer is prolonged.
Description
Technical field
The utility model relates to a kind of oil tank of transformer shell, particularly a kind of high-power transformer tank envelope with reinforcement.
Background technology
High-power transformer is the important equipment of electric power system, and its fail safe has directly affected the safe operation of electric power system.Fuel tank is the main load bearing component of transformer; especially jumbo transformer; the general oil-filled transformer of selecting; the fuel tank of oil-filled transformer is the shell of protection transformer body and contains oily container; be again the skeleton of assembling transformer external structure part, the heat simultaneously by transformer, the loss of device body being produced is dissipated in atmosphere with convection current and radiation mode.As oil holder, particularly contain deep fat container, should reach indeformable, the leakage of oil that do not ftracture, this just requires fuel tank should possess certain mechanical strength.
On the housing of high-power transformer fuel tank, be located at the intensity that reinforcement can strengthen fuel tank, the reinforcing rib structure of the medium-and-large-sized oil tank of transformer of prior art great majority adopt two kinds: a kind of is square or closely square, add that outside certain thickness steel plate makes reinforcement; Another kind is corrugated type, with corrugation, does reinforcement effect.But above-mentioned two kinds of reinforcements can only play structural strengthening effect, can not reduce the noise of transformer, and the effect of structural strengthening neither be the most remarkable.
In recent years, at house and public arena, applied more and more large-scale power transformer, this has just proposed requirement to the noise of high-power transformer, how to reduce high-power transformer noise and has become power transformer manufacturing urgent problem.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of reinforcing rib structure of high-power transformer fuel tank, in the structural strength of strengthening transformer, can also significantly reduce transformer noise, energy-conserving and environment-protective.
For solving the problems of the technologies described above, a kind of high-power transformer fuel tank shell, comprises body, it is characterized in that:
On the surrounding lateral wall of described body, be laid with reinforcement, this reinforcement is several rectangle cavitys, and this cavity is fixed on the lateral wall of body; In described cavity, be filled with yellow sand; Distance between two sides parallel with body lateral wall of described cavity is 10-20cm, and the wall thickness of this cavity is 6-9mm.
Wherein, the spacing of described adjacent two cavitys is 40-80cm.Such design, had both guaranteed the intensity of transformer to have reduced again noise.
Wherein, described cavity is fixed on the surrounding lateral wall of casing by the mode of welding.
Wherein, the filling rate of the yellow sand in described cavity is 95%, and the particle diameter of yellow sand is about the dry fine sand of 1-1.5mm.This design, can reduce the noise of transformer effectively, by noise in transmittance process from inside to outside by yellow sand damping.
Compared with prior art, the utility model has the advantages that:
The technical problem that the utility model solves is that the noise of high-power transformer is very large, has brought puzzlement to resident around.The cabinet shell of described high-power transformer fuel tank is provided with cavity, is filled with yellow sand in cavity, can not only increase the intensity of transformer, can also significantly reduce transformer noise.When noise is in transmittance process from inside to outside, be reinforced the yellow sand damping in muscle, so can effectively reduce noise, can be applicable to house and public place, widened range of application.Cavity, as reinforcement, can increase the intensity of transformer, postpones the useful life of transformer.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, Figure 2 and Figure 3, a kind of high-power transformer fuel tank shell, comprises body 3, it is characterized in that: on the surrounding lateral wall of described body 3, be laid with reinforcement, this reinforcement is several rectangle cavitys 1, and this cavity 1 is fixed on the lateral wall of body 3; In described cavity 1, be filled with yellow sand 2; Distance between two sides parallel with body lateral wall of described cavity 1 is 10-20cm, and the wall thickness of this cavity 1 is 6-9mm.
Wherein, the spacing of described adjacent two cavitys 1 is 40-80cm.
Wherein, described cavity 1 is fixed on the surrounding lateral wall of casing by the mode of welding.
Wherein, the filling rate of the yellow sand in described cavity 1 is 95%, and the particle diameter of yellow sand is about the dry fine sand of 1-1.5mm.
Body 3 outside welds at high-power transformer fuel tank shell are connected to some rectangle cavitys 1 arranged in a uniform, the cuboid that this cavity 1 forms for the steel plate bending of thickness 8mm.In cuboid, be filled with yellow sand, this yellow sand is fine sand, and particle diameter is 1-1.5mm.The spacing of adjacent two cavitys 1 is 40-80cm, so not only can proof strength, and can also effectively intercept noise.When noise from inside to outside in oil tank of transformer in transmittance process, by the yellow sand damping in cavity 1, so can effectively reduce noise, solved the problem that noise disturbs residents.And cavity 1 is as reinforcement, can also increase the intensity of transformer, postpone the useful life of transformer.Fig. 4 and Fig. 5 are the structural representation of transformer oil tank shell of the prior art, and reinforcement does not have and falls low noise effect.
More than show and described basic principle of the present utility model and principal character and advantage thereof.The technology personage of the industry should understand; the utility model is not subject to the restriction of above-mentioned implementing regulations; what in above-mentioned implementing regulations and specification, describe is for principle of the present utility model is described; do not departing under the prerequisite of the utility model principle and scope; the utility model also can have various changes and modifications, and these changes and improvements all belong within the scope of claimed the utility model.
The claimed scope of the utility model defines with appending claims and other equivalent.
