Abstract
The utility model relates to a winding transposition structure of a large transformer and belongs to the technical field of large transformer manufacturing. The technical scheme adopted by the utility model is as follows: a horn-shaped cushion block (2) is arranged between two adjacent wire discs of a winding (1), and the position of the horn-shaped cushion block (2) is matched with the inner radius and outer radius of the winding (1); one side of the horn-shaped cushion block (2) is tightly adhered to the adjacent arc surfaces of the wire discs, and the other side of the horn-shaped cushion block (2) is flush with the inner diameters or outer diameters of the wire discs; the horn-shaped cushion block (2) is made of laminated paper sheets and is horn-shaped; the heights and widths of two ends of the horn-shaped cushion block (2) are matched with the thickness and width of wires of the winding; the length of the horn-shaped cushion block (2) is matched with the inner radius and outer radius of the winding. The winding transposition structure has the beneficial effects of preventing the wire discs of the winding from being subjected to a loosening phenomenon during vacuum drying and oil impregnation processes, therefore effectively enhancing the radial consolidation degree of the wire discs, improving the mechanical strength and short circuit resistance of the winding and ensuring the safe operation of the transformer.
Description
Technical field
The utility model relates to a kind of Coefficients of Large Power Transformer Winding transposition structure, belongs to high-power transformer manufacturing technology field.
Background technology
In high-power transformer, generally all have transposition between the adjacent lines cake of winding, when transposition is during without any filling, the width of winding is to, the not state of consolidation loose by there will be, and the vacancy simultaneously causing due to transposition also can affect the aesthetic property of winding; For avoiding above-mentioned phenomenon; conventionally can fill common insulating board filler strip in transposition; and because common insulating board filler strip is in vacuumize and immersion oil process; often shrink more or distortion; make the width of winding loose to also there will be, the state of consolidation not; thereby the anti-short circuit capability of winding is reduced, leave hidden danger to the safe operation of transformer.
Utility model content
The utility model object is to provide a kind of Coefficients of Large Power Transformer Winding transposition structure, completes transition and the radial filling of line cake of winding transposition wire with oxhorn cushion block, improves mechanical strength and the anti-short circuit capability of winding, solves the problem existing in background technology.
The technical solution of the utility model is:
A kind of Coefficients of Large Power Transformer Winding transposition structure, comprise winding and oxhorn cushion block, oxhorn cushion block is located between adjacent two line cakes of winding, inside radius and the outer radius of position and winding match, the oxhorn cushion block one side arc surface adjacent with line cake is close to, another side is concordant with line cake internal diameter or external diameter, described oxhorn cushion block is that laminated paper board is made, be ox horn shape, thickness and the width of the height at oxhorn cushion block two ends and width and winding conducting wire match, and the length of oxhorn cushion block and winding inside radius and outer radius match.
Described oxhorn cushion block is placed in the transposition that conductor thickness is greater than 10mm.
The beneficial effects of the utility model are: complete transition and the radial filling of line cake of winding transposition wire with oxhorn cushion block, avoid winding wire cake to occur the phenomenon that fluffs in vacuumize and immersion oil process, thereby the effectively radial consolidation degree of splicing thread cake, improve mechanical strength and the anti-short circuit capability of winding, guarantee the safe operation of transformer.
Accompanying drawing explanation

Fig. 2 is the utility model oxhorn cushion block front view;
Fig. 3 is the utility model oxhorn cushion block vertical view;
In figure: winding 1, oxhorn cushion block 2, outside transposition 3, bottom transposition 4.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of Coefficients of Large Power Transformer Winding transposition structure, comprise winding 1 and oxhorn cushion block 2, oxhorn cushion block 2 is located between adjacent two line cakes of winding 1, inside radius and the outer radius of position and winding 1 match, the oxhorn cushion block 2 one side arc surface adjacent with line cake is close to, and another side is concordant with line cake internal diameter or external diameter.
Described oxhorn cushion block 2 is laminated paper board making, thickness direction is the pressing direction of laminated paper board, place in winding transposition for convenient, shape, the parameter of oxhorn cushion block need meet certain requirement, with reference to accompanying drawing 2,3, oxhorn cushion block 2 is ox horn shape, and size R can be according to the placement location difference of oxhorn cushion block 2 value is winding respectively inside radius and outer radius, and height h, the H at oxhorn cushion block 2 two ends, left and right and width W can be determined and choose suitable value according to the thickness of wire and width; The length L of oxhorn cushion block 2 can be determined and choose suitable value according to the interval of winding inside radius and outer radius and winding transposition.Oxhorn cushion block 2 is greater than the transposition of 10mm for filling wire.
Claims (2)
1. a Coefficients of Large Power Transformer Winding transposition structure, it is characterized in that comprising winding (1) and oxhorn cushion block (2), oxhorn cushion block (2) is located between adjacent two line cakes of winding (1), inside radius and the outer radius of position and winding (1) match, oxhorn cushion block (2) the one side arc surface adjacent with line cake is close to, another side is concordant with line cake internal diameter or external diameter, described oxhorn cushion block (2) is laminated paper board making, be ox horn shape, the height at oxhorn cushion block (2) two ends and thickness and the width of width and winding conducting wire match, the length of oxhorn cushion block (2) and winding inside radius and outer radius match.
