Abstract
The invention relates to an oil tank for an oil immersion type transformer, which is used for lowering noise of the oil immersion type transformer and comprises an oil tank body. A layer of tank wall structure is arranged at the outer side of the oil tank body, and a preset air gap is arranged between the tank wall structure and the oil tank body. Flame-retardant and sound-absorbing materials] are lined in the air gap. The tank wall structure and the oil tank body are fixedly connected with a radiator pipe of the oil immersion type transformer in an electric welding way. The invention achieves the effect of noise reduction by improving the structure of the oil tank, has simple structure, convenient processing, favorable concealment and favorable practicability, and can efficiently reduce the noise generated in operation of the transformer, thereby the noise pollution brought by the environment is improved.
Description
Technical field
The present invention relates to transformer, relate in particular to a kind of oil tank for oil immersion type transformer.
Background technology
There is certain noise in existing transformer when operation, particularly under the bigger situation of duty ratio, the noise that transformer sends is particularly evident, transformer noise mainly comes from magnetostriction unshakable in one's determination and that basket vibration causes, parameters such as magnetic is close, the geometry of seam, steel disc quality unshakable in one's determination and manufacturing process are all affecting the transformer magnetoconstriction, even under all standard compliant situation of above-mentioned parameter, transformer noise still can't be eliminated.
In order to reduce noise, present existing solution is to install various sound-absorbings, acoustic material additional in the fuel tank periphery, perhaps builds a soundproof room more in addition and comes noise reduction.Yet at oil tank of transformer outside installing sound-absorbing or acoustic material, take up room and obviously strengthen, the fixed support difficulty, and influence the heat dispersion of fuel tank greatly.If build the soundproof room of a special use, equipped good ventilation and heat facility, noise reduction can obviously promote, but cost is too high, and cost performance is not ideal enough.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the present invention aims to provide a kind of improved oil tank for oil immersion type transformer, reduces at the transformer noise that sends in service with realization, thereby improves the purpose of giving the noise pollution that environment brought.
A kind of oil tank for oil immersion type transformer of the present invention, be used to reduce the noise of described oil-filled transformer, it comprises the fuel tank body, it is characterized in that: be provided with one deck tank wall structure in the described fuel tank body outside, and be provided with the air gap of presetting between this tank wall structure and described fuel tank body.
In above-mentioned oil tank for oil immersion type transformer, in described air gap, be lined with fire-retardant, sound-absorbing material.
In above-mentioned oil tank for oil immersion type transformer, described tank wall structure and fuel tank body are connected and fixed by the radiator tube of electric welding mode and described oil-filled transformer.
Owing to adopted above-mentioned technical solution, the present invention is by improving the structure of fuel tank, reach the effect of noise reduction, and it is simple in structure, easy to process, its cost increases few, but performance is remarkable, can reduce effectively at the transformer noise that sends in service, give the noise pollution that environment brought thereby improve.
Description of drawings
Fig. 1 is the structure cutaway view of a kind of oil tank for oil immersion type transformer of the present invention.
Embodiment
As shown in Figure 1, the present invention, it is a kind of oil tank for oil immersion type transformer, be used to reduce the noise of oil-filled transformer, comprise fuel tank body 1 and one deck tank wall structure 2 that is arranged on fuel tank body 1 outside, and 1 of tank wall structure 2 and fuel tank body are provided with the air gap of presetting, and are lined with fire-retardant, sound-absorbing material 3 in the air gap.
In the present invention, the original hermetically-sealed construction of oil-filled transformer is born by fuel tank body 1, and tank wall structure 2 and fuel tank body 1 are connected and fixed by the radiator tube 4 of electric welding mode and oil-filled transformer.
When transformer noise reaches this double-deck Oiltank structure, produce the damping action of sound wave by air layer and sound-absorbing material, can weaken greatly, thereby noise of transformer is reduced.Facts have proved the 4-5dB that to descend.
In sum, the present invention is simple in structure, easy to process, have good disguise and practicality, from finished product, be as good as with general oil immersion-type distribution transformer, by simply and effectively improving existing Oiltank structure, limited the propagation of noise of transformer from the source, reduce all round noise pollution of environment effectively, for people have created a kind of peacefulness, harmonious power utilization environment, be a kind of structural design of environment-friendly type.
Below embodiment has been described in detail the present invention in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
