Abstract
The invention discloses a kind of three dimensional wound core transformer to draw screw-rod structure, including three dimensional wound core and drawing screw rod, it is characterised in that the three dimensional wound core forms triangle rod structure by three single frame iron core combinations；Drawing screw rod being axially disposed within described in any two in the gap of single frame iron core connecting portion along the three dimensional wound core.A kind of three dimensional wound core transformer of the present invention draws screw-rod structure, by the position adjustment for drawing screw rod in single frame iron core after splicing remaining gap, then it to be fixed by folder spacing.Such structure design can both improve axis of winding tightening force, effectively reduce the electrical distance for drawing screw rod and coil, improve transformer anti-short circuit capability, while also reduce the difficulty of transformer overall construction design, add transformer aesthetics.
Description
Technical field
The present invention relates to a kind of three dimensional wound core transformer for three dimensional wound core field transformer to draw screw-rod structure.
Background technology
With deepening continuously for the energy-saving policy in China, country has put into effect serial policy and has encouraged to develop energy-saving, low noise
Sound, amorphous dry-type transformer product.Once once seen as high load, low-loss amorphous alloy dry-type transformer market prospects
Good, amorphous three-dimensional wound core dry type transformer will become preferably dry-type transformer of new generation.The three dimensional wound core of existing market
Transformer, it draws the position of screw rod to be all disposed within the alternate of coil, and such structure causes to draw screw rod to be located at coil triangular prism model
Outside in enclosing, the overall construction design and performance of transformer are have impact on, makes structure design layout difficult, and have impact on transformer
Overall appearance.
The content of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of three dimensional wound core transformer to draw screw rod knot
Structure, it is easily achieved, it is possible to increase the axial tightening power of transformer, avoids generation between screw rod and transformer high-voltage coil and set
Distance is counted, strengthens the anti-short circuit capability of transformer, reduces the design cost of transformer, improve transformer overall aesthetic degree.
Realizing a kind of technical solution of above-mentioned purpose is：A kind of three dimensional wound core transformer draws screw-rod structure, including solid
Rewinding material and drawing screw rod, it is characterised in that the three dimensional wound core forms triangle rod structure by three single frame iron core combinations；It is described
Draw screw rod being axially disposed within described in any two in the gap of single frame iron core connecting portion along the three dimensional wound core.
Further, the three dimensional wound core transformer draws screw-rod structure to further include three dimensional wound core folder, the three-dimensional winding
Core clamping is coated on the outside of the three dimensional wound core, and the drawing screw rod is combined closely with the three dimensional wound core.
Further, it is axially arranged with middle drawing spiral shell along the three dimensional wound core in the center of the three dimensional wound core
Bar, the middle drawing screw rod are equipped with three screw rod arms, and every screw rod arm all faces the drawing screw rod.
A kind of three dimensional wound core transformer of the present invention draws screw-rod structure, and the position adjustment for drawing screw rod is existed for single frame iron core
After splicing in remaining gap, then it is fixed by folder spacing.Such structure design can both improve around
Group axial tightening power, effectively reduces the electrical distance for drawing screw rod and coil, improves transformer anti-short circuit capability, while also reduce
The difficulty of transformer overall construction design, adds transformer aesthetics.
Brief description of the drawings
Fig. 1 is that a kind of three dimensional wound core transformer of the present invention draws the structural representation top view of screw-rod structure.
Embodiment
In order to preferably understand technical scheme, below by specifically embodiment and with reference to attached drawing
It is described in detail：
Referring to Fig. 1, a kind of three dimensional wound core transformer of the present invention draws screw-rod structure, including three dimensional wound core 2 and drawing
Screw rod 1, three dimensional wound core 1 form triangle rod structure by three single frame iron core combinations.Since single frame iron core is rectangle, any two
A single frame iron core can leave one of gap in stitching section after splicing.Draw being axially disposed within along three dimensional wound core 1 of screw rod 2
In the gap.Three dimensional wound core transformer draws screw-rod structure to further include three dimensional wound core folder 3, which wraps
The outside of three dimensional wound core 2 is overlayed on, drawing screw rod is combined closely with three dimensional wound core, forms an overall structure.In three-dimensional winding iron
The center of the heart 2 draws screw rod 4 to be equipped with three screw rod arms 41 along middle draw that be axially arranged with of three dimensional wound core 2 among screw rod 4, every
Screw rod arm 41 all faces a drawing screw rod 1.
Such drawing screw-rod structure design, screw rod will be drawn to be arranged on two high-tension coils alternate in the prior art by eliminating
Structure, it is possible to increase the axial force of three dimensional wound core transformer, makes iron-core transformer obtain more preferable axial stability, lifting
The anti-short circuit capability of low pressure winding, while also enhance the aesthetics of three dimensional wound core transformer.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
