Abstract
The utility model relates to a low-noise dry transformer, comprising an iron core, at least one group of high-tension windings, and at least one group of low-tension windings, wherein the high-tension windings and the low-tension windings are wound on the iron core and correspond to each other one by one; a gap exists between the high-tension winding and the low-tension winding; and a shockproof rubber gasket is arranged at the gap between the high-tension winding and the low-tension winding. The low-noise dry transformer overcomes the defects that in the prior art, a dry transformer is severe in vibration and noisy in working; and as the shockproof rubber gasket is arranged between a high-tension winding coil and a low-tension winding coil of the dry transformer, the noise of the traditional dry transformer is reduced, and the loss of equipment is reduced.
Description
Technical field
The utility model has designed a kind of low-noise dry type transformer, belongs to electronic technology field.
Background technology
Traditional dry-type transformer is a double-winding structure, and promptly one group of high and low pressure coil is enclosed within on the same iron core column and realizes.But when needing many transformers to supply power simultaneously as if some equipment, then must use many transformers simultaneously, this supply power mode floor space is big, and cost is high.Along with the continuous development of Dry-Transformer Technology, manufacturers begin to be enclosed within simultaneously on the same core limb organizing the high and low pressure coil more, realize that a dry-type transformer accomplishes the purpose of multiple load power supply, and floor space are little, and cost is low.Yet,, makes that the concussion between the coil is violent, thereby produced huge noise, and this concussion of long-term existence also causes damage to equipment easily owing to adopted many groups high and low pressure coil.
The utility model content
The utility model provides a kind of low noise dry-type transformer, and can not only satisfy provides multiple load power supply simultaneously, and the equipment noise is low, long service life.
The technical scheme that the utility model adopted is: a kind of low-noise dry type transformer; Comprise iron core, at least one group of high pressure winding and at least one group of low pressure winding; Said high pressure winding and low pressure winding are coaxial to be enclosed within on the iron core; The high pressure winding is corresponding one by one with the low pressure winding, and has the gap between high pressure winding and the low pressure winding, it is characterized in that: the gap location between said high pressure winding and low pressure winding is equipped with the Shockproof rubber pad.
Aforesaid a kind of low-noise dry type transformer is characterized in that: the quantity of high pressure winding and low pressure winding all is 3.
Aforesaid a kind of low-noise dry type transformer is characterized in that: be provided with cushion block between said adjacent two low pressure windings.
Aforesaid a kind of low-noise dry type transformer is characterized in that: described low pressure winding adopts spiral winding construction.
Aforesaid a kind of low-noise dry type transformer is characterized in that: described high pressure winding adopts segmented layered winding construction.
Aforesaid a kind of low-noise dry type transformer is characterized in that: the cross section of described iron core is a regular polygon.
The beneficial effect of the utility model is: the utility model has reduced the noise of conventional dry transformer through between the high pressure winding coil of dry-type transformer and low pressure winding coil, the Shockproof rubber pad being installed, and has reduced the loss of equipment.Simultaneously, a plurality of high and low pressure winding coils are fixed on the same core limb, have increased the utilance of iron core, reduced cost.
Description of drawings
Fig. 1 is the structural representation of low-noise dry type transformer.
Embodiment
To combine Figure of description below, the utility model will be further described.
As shown in Figure 1; A kind of low-noise dry type transformer comprises iron core 1, three groups of high pressure windings 2 and three groups of low pressure windings 3, and said high pressure winding 2 is enclosed within on the iron core 1 with low pressure winding 3; Its mesohigh winding 2 adopts segmented layered winding construction; Low pressure winding 3 adopts spiral winding construction high pressure winding 2 corresponding one by one with low pressure winding 3, and has the gap between high pressure winding 2 and the low pressure winding 3, and the gap location between said high pressure winding 2 and low pressure winding 3 is equipped with Shockproof rubber pad 23; And between adjacent two low pressure windings 2, be provided with cushion block 32, through the coupling between cushion block 32 minimizing low pressure windings.
During dry-type transformer work,, greatly reduce the vibrations of transformer body, reduced the noise of dry-type transformer largely owing to the shock-absorbing effect that rubber sheet gasket 23 is played.
In sum, the low-noise dry type transformer that the utility model provides, can not only satisfy provides multiple load power supply simultaneously, has reduced the noise of conventional dry transformer, has reduced the loss of equipment, has increased the utilance of iron core, has reduced cost.
More than show and described basic principle, principal character and the advantage of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range by appending claims and equivalent circle thereof.
