Abstract
The utility model provides a kind of noise-reduction transformer, including upper clamping piece, iron core and coil, further includes the sound absorbing paper for wrapping up coil encircling；Sound absorbing paper is bonded by one layer of corrugated paper and one layer of crimped paper by resin glue, and wherein corrugated paper is in the side far from coil, and crimped paper is in close to the side of coil；The end of sound absorbing paper is ligatured by cloth bag and is fixed；Tectorial paper is also enclosed on iron core, tectorial paper is formed by insulating paper and Film laminated.The technical solution of the utility model, be cladded with lid sound absorbing paper in coil and in iron core outer wrapping tectorial paper by way of, can effectively reduce equipment operation noise 3~5dB.Also, the systemic circulation that a heat conduction is formed between the upper and lower gap and fuel tank between sound absorbing paper and device body, transformer Wen Sheng can also be reduced while improving the electric strength between transformer coil and fuel tank.The technical solution is not only simple in structure, is of low cost, also the advantageous effect with killing three birds with one stone.
Description
Technical field
The utility model is related to transformers, and in particular to a kind of noise-reduction transformer.
Background technology
Transformer acts as indispensable role in power supply system, the usage quantity and use scope of transformer also pole
Extensively, the transformer that is placed in residential block or factory often due to its operating noise and resident and worker are caused larger tired
It disturbs, noise pollution is caused to environment, seriously affected people’s lives working environment.Existing transformer is in noise reduction and heat dissipation
Aspect cannot reasonably coordinate, and the heat dissipation performance of excellent noise reduction effect is poor, and the anti-acoustic capability of good heat dissipation effect is poor, influences transformer
Overall performance.
Utility model content
The purpose of the utility model is to overcome disadvantage existing in the prior art, a kind of not only excellent noise reduction effect is provided and
And contribute to the noise-reduction transformer of cooling.
To achieve the goals above, the technical solution adopted in the utility model is as follows：
A kind of noise-reduction transformer, including upper clamping piece, iron core and coil further include the sound absorbing paper for wrapping up coil encircling；
Sound absorbing paper is bonded by one layer of corrugated paper and one layer of crimped paper by resin glue, and wherein corrugated paper is in one far from coil
Side, crimped paper are in close to the side of coil；The end of sound absorbing paper is ligatured by cloth bag and is fixed；Overlay film is also enclosed on iron core
Paper, tectorial paper are formed by insulating paper and Film laminated.
Further, the thickness of crimped paper is 0.8mm.
Further, the corrugation height of corrugated paper is 5mm, thickness 1.5mm.
Further, corrugated paper center line is the function of sine curve f (x)=1.85sin [(2 π/17) × x].
The technical solution of the utility model, by being cladded with lid sound absorbing paper in coil and in iron core outer wrapping tectorial paper
Mode can effectively reduce by 3~5dB of equipment operation noise.Also, Oil Guide channel is formed between sound absorbing paper, device body, fuel tank, is allowed to
Cold and hot oily convection circulation is preferably completed, change can also be reduced while improving the electric strength between transformer coil and fuel tank
Depressor Wen Sheng.The technical solution is not only simple in structure, is of low cost, also the advantageous effect with killing three birds with one stone.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sound absorbing paper structural schematic diagram of the utility model.
Specific implementation mode
The utility model will be further described below in conjunction with the accompanying drawings.
With reference to attached drawing.The utility model includes upper clamping piece, iron core and coil, further includes the sound-absorbing for wrapping up coil encircling
Paper 1；Sound absorbing paper 1 is bonded by one layer of corrugated paper 2 and one layer of crimped paper 3 by resin glue, and wherein corrugated paper 2 is in separate
The side of coil, corrugation height are 5mm, thickness 1.5mm；Crimped paper 3 is in close to the side of coil, thickness 0.8mm.It inhales
The end of sound paper 1 is ligatured by cloth bag and is fixed.Particularly, tectorial paper is also enclosed on iron core, tectorial paper is by insulating paper and film
It is combined.
Particularly, corrugated paper center line is the function of sine curve f (x)=1.85sin [(2 π/17) × x].
It should be pointed out that be described above the embodiments of the present invention.However, the technical staff of art technology should manage
Solution, the present utility model is not limited to the above embodiments, only illustrates the principles of the present invention described in above-described embodiment,
There are many changes and improvements for the utility model also meeting under the premise of not departing from the scope of the utility model, these changes and improvements are all
It falls into claimed the scope of the utility model.
