Abstract
The utility model discloses a noise reduction structure of a power transformer. The noise reduction structure is characterized in that a rubber plate with the thickness ranging from 5mm to 10mm is added between a magnetic screen and the inner wall of an oil tank, and the magnetic screen and the rubber plate are clamped on the inner wall of the oil tank by a clip welded on the inner wall of the oil tank. Noise which is generated by a body of the power transformer with the noise reduction structure and transmitted to the outside of the transformer is reduced, so that the purpose of reducing the noise of the transformer is achieved. In addition, the noise reduction structure is simple and is low in cost, and the noise can be reduced by 1-2dB.
Description
Technical field
The utility model belongs to the manufacturing field of power transformer, relates to a kind of denoising structure of power transformer.
Background technology
Along with the development of society, the enhancing of people's environmental consciousness, the customer requirements noise of transformer is more and more littler.In particular for the transformer that the substation in shopping centre and the residential block uses, noise requirements is littler.Noise of transformer is contaminated environment not only, and harm humans is healthy again.Noise of transformer is the same with other electric property and the mechanical performance of transformer, all is the important technology parameter of transformer.Therefore, the height of transformer noise level becomes the important indicator of weighing design of transformer production producer and manufacture level.In order to satisfy user's requirement, simple through reducing the transformer core magnetic flux density, reduce the noise that produces unshakable in one's determination, will increase the transformer cost greatly, make transformer very uneconomical.
The utility model content
The purpose of the utility model is exactly to solve the problems referred to above that exist in the prior art, and the denoising structure of the power transformer that a kind of noise is little, cost is low is provided.
For addressing the above problem; The technical solution of the utility model is: a kind of denoising structure of power transformer; It is between magnetic screen and inner wall of oil tank, to increase the thick rubber slab of one deck 5-10mm, and the clamp that is welded on the inner wall of oil tank is connected to magnetic screen and rubber slab on the inner wall of oil tank.
Adopt the power transformer of the utility model denoising structure, weakened the transmission of noise outside transformer that transformer body produces, thereby reached the purpose that reduces transformer noise.It is simple in structure, and cost is low; Can reduce noise 1～2dB.
Description of drawings
Fig. 1 is installed in the structural representation on the transformer-cabinet inwall for the utility model;
Fig. 2 is the right view of Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2, present embodiment is between magnetic screen 1 and inner wall of oil tank 4, to increase the thick rubber slab 2 of one deck 5-10mm, with the clamp 3 that is welded on the inner wall of oil tank 4 magnetic screen and rubber slab is connected on the inner wall of oil tank 4 together again.
