Abstract
The utility model provides a sound-insulation noise-reduction oil tank of an oil-immersed transformer. The sound-insulation noise-reduction oil tank comprises an oil tank cover, oil tank walls, a finned radiator and a base, wherein the oil tank walls are in a double-layer structure and comprise an inner-layer tank wall and an outer-layer tank wall, a sound-insulation felt is filled between the inner-layer tank wall and the outer-layer tank wall, and tubes of the finned radiator pass through the oil tank walls in the double-layer structure, are fixed on the oil tank walls in a welding mode and are fully welded on the inner-layer tank wall to prevent oil leakage. The sound-insulation noise-reduction oil tank can achieve the effect of reducing noise of the transformer through the improvement of the structure of an original oil tank, is simple in structure, convenient to process, good in hidden performance and practicality, and capable of effectively reducing the noise in the operation process of the transformer so as to solve the problem of noise pollution to the environment, and can simultaneously achieve, through arrangements of different layers of sound-insulation felt, different sound-insulation noise-reduction effects to meet different requirements of different customers for noise reduction of the transformer.
Description
Technical field
The utility model patent relates to a kind of sound insulation and noise reduction fuel tank of oil-filled transformer, can effectively reduce the noise of transformer, is specially adapted to the oil immersed amorphous alloy iron core transformer.
Background technology
At present, the tank wall of the fuel tank of traditional distribution transformer is single layer structure.In order to reduce the noise of transformer, usually also being the most effective way, be exactly the magnetic flux density that reduces transformer core when design, but this uses the consumption that will increase the main materials such as silicon steel sheet, copper material, cause the cost of transformer obviously to increase, this is very uneconomical.And after in a single day transformer made finished product, its noise level had also just been determined, just is difficult to reduce noise by other method again.
The utility model content
In view of this, be necessary the problem mentioned for background technology to provide a kind of need not that transformer body is not done any adjustment, do not increased the Novel oil-immersed transformer fuel tank that more cost just can reduce noise.
The utility model is achieved through the following technical solutions:
A kind of sound insulation and noise reduction fuel tank of oil-filled transformer, it comprises fuel tank cap, oil tank wall, gilled radiator and base, described gilled radiator comprises the pipe that is connected with described oil tank wall, it is characterized in that, the oil tank wall of described fuel tank is double-decker, comprises internal layer tank wall and outer enclosure wall, places the sound-insulating felt of the different numbers of plies according to the requirement of defening effect between described internal layer tank wall and the outer enclosure wall, the pipe of described gilled radiator passes described double-layer tank wall, and is fixedly welded on the described oil tank wall.
Compared with prior art, the utility model possesses following advantage:
The utility model does not need the device body of transformer is done any improvement, only by improving the structure of fuel tank, reaches the effect that reduces transformer noise, this Oiltank structure is simple, easy to process, substantially the same with the traditional transformer fuel tank in appearance, have good disguise and practicality; Can effectively reduce the noise that sends at Transformer, thereby improve the noise pollution that brings to environment.Simultaneously, can also by placing the number of plies of different described sound-insulating felts, reach different sound insulation and noise reduction effects, to satisfy different clients to the different requirements of transformer noise.
The utility model fuel tank simple in structure, cost increases few, and noise reduction is obvious, and the noise level of finished product is adjustable, and same device body can reach different noise levels, satisfies the demand without the client.
Description of drawings
Fig. 1 is the cross sectional representation of the utility model embodiment.
Embodiment
As shown in Figure 1, present embodiment provides a kind of sound insulation and noise reduction fuel tank of oil-filled transformer, it comprises fuel tank cap 5, oil tank wall, gilled radiator 4 and base 6, described gilled radiator 4 comprises the pipe 41 that is connected with described oil tank wall, described oil tank wall is double-decker, comprise internal layer tank wall 21 and outer enclosure wall 22, require to fill one or more layers sound-insulating felt 3 according to defening effect between described internal layer tank wall 21 and the outer enclosure wall 22, the pipe 41 of described gilled radiator 4 passes described double-layer tank wall, and is fixedly welded on the described oil tank wall.Concrete, the root weld of the pipe 41 of described gilled radiator 4 is in the inner surface of described internal layer tank wall 21, and described internal layer tank wall 21 and outer enclosure wall 22 are run through in its end.
Full weld between the pipe 41 of described gilled radiator 4 and the described internal layer tank wall 21 prevents leakage of oil.
The utility model is not limited to above-mentioned two kinds of technical schemes that execution mode is described, and all technical schemes of conceiving based on the present utility model all belong to the utility model protection range.For example, described sound-insulating felt can be replaced by Sound-proof material, abatvoix, or only is vacuum, all can realize soundproof effect.
Claims (2)
1. the sound insulation and noise reduction fuel tank of an oil-filled transformer, it comprises fuel tank cap, oil tank wall, gilled radiator and base, described gilled radiator comprises the pipe that is connected with described oil tank wall, it is characterized in that, the oil tank wall of described fuel tank is double-decker, comprise internal layer tank wall and outer enclosure wall, place the sound-insulating felt of the different numbers of plies according to the requirement of defening effect between described internal layer tank wall and the outer enclosure wall, the pipe of described gilled radiator passes described double-layer tank wall, and is fixedly welded on the described oil tank wall.
