Abstract
The invention relates to a low-noise dry type transformer which comprises an iron core, at least one group of high-voltage winding and at least one group of low-voltage winding, wherein the high-voltage winding and the low-voltage winding are sleeved on the iron core; the high-voltage winding corresponds to the low-voltage winding one to one, and a clearance is arranged between the high-voltage winding and the low-voltage winding; and the clearance between the high-voltage winding and the low-voltage winding is provided with a shockproof rubber gasket. The low-noise dry type transformer overcomes the defects of violent vibration and loud noise generated when the dry type transformer works in the prior art; by installing the shockproof rubber gasket between a high-voltage winding coil and a low-voltage winding coil of the dry type transformer, the noise of the traditional dry type transformer is reduced, and the loss of the equipment is reduced.
Description
Technical field
The present invention 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.
Summary of the invention
The invention provides a kind of low noise dry-type transformer, can not only satisfy provides multiple load power supply simultaneously, and the equipment noise is low, long service life.
The technical scheme that the present invention 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 invention has the beneficial effects as follows: the present invention 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 present invention 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, reduce the coupling between the low pressure winding through cushion block.
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, low-noise dry type transformer provided by the invention, 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 of the present invention, principal character and advantage.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range by appending claims and equivalent circle thereof.
