The soft connecting part is arranged on the outer side of a low-voltage coil. The radian oblique angle copper bar is welded to one end of the soft connecting part. The soft connecting part is placed in a gap between a high-voltage coil and the low-voltage coil in a folding mode. The radian oblique angle copper bar has inward bending radian which is concentric with a winding inner mould and an iron core, and the inward bending radian is the same as winding inner mould radian. The height of the radian oblique angle copper bar increases from the far end to the close end of the soft connecting part in an oblique-angle mode, and the radian oblique angle copper bar is connected with the soft connecting part at the highest position. The three-dimensional rolling iron core dry type transformer foil winding low-voltage coil leading-out bar guarantees the sizes of the coils, coil winding is convenient, under the situation that the section requirements of low-voltage currents on the copper bar, copper bar using quantity is saved as much as possible, and production cost is lowered.
Description
Technical field
The utility model relates to a kind of low voltage winding in transformers and draws row, and specifically a kind of three-dimensional coiled core dry-type paper tinsel is drawn row around low-voltage coil.
Background technology
, although three-dimensional coiled core dry-type has the not only loss of reduction own but also saves the dual-energy-saving advantage of producing material, needs the ribbon core coiling in its production process, produce comparatively difficulty.Especially row is drawn in the low pressure of low-voltage coil, from traditional plane iron core dry-type transformer low pressure draw drained entirely different, how in the situation that do not increase cost and draw smoothly and become a great problem.
Summary of the invention
The purpose of this utility model is to provide a kind of three-dimensional coiled core dry-type paper tinsel and draws row around low-voltage coil, this row of drawing do to become for three-dimensional winding iron core the characteristics specialized designs that low-voltage coil must the ribbon core coiling, with minimum cost, has realized that the low-voltage coil terminal draws.
The purpose of this utility model is achieved through the following technical solutions:
A kind of three-dimensional coiled core dry-type paper tinsel is drawn row around low-voltage coil, it is characterized in that: this is drawn package and draws together and be arranged on being flexible coupling and being welded on the radian oblique angle copper bar of the end that is flexible coupling of the low-voltage coil outside, and this is flexible coupling in the folding space that is placed between high-tension coil and low-voltage coil; Radian oblique angle copper bar has inside crooked radian, and crooked radian is concentric with coiling internal mold and iron core, and identical with coiling coiling internal mold radian; The height of radian oblique angle copper bar is that oblique angle increases and at highest point, is connected with being flexible coupling to near-end by the distance far-end that is flexible coupling.
In the utility model, the height that is flexible coupling is identical with the maximum height of radian oblique angle copper bar.Radian oblique angle copper bar is the oblique triangle with radian, and the paper tinsel material is welded on the hypotenuse of oblique triangle.
In the utility model, draw winding displacement circle inside and be divided into radian oblique angle copper bar.Wherein radian, oblique angle are two characteristics of the utility model maximum.Radian: this part copper bar is with the radian that curves inwardly, and crooked radian is concentric with coiling internal mold and iron core, well is dissolved into during coiling in low-voltage coil, does not take redundant space, has guaranteed the size of low-voltage coil.Oblique angle: because low-tension current is delivered in the row of drawing through Copper Foil, flow out from the row's of drawing high order end terminal finally, this section copper bar and Copper Foil welding, electric current is to be pooled to high order end from the low order end of paper tinsel material, slowly increase from the low order end to the high order end from the electric current of drawing drainage, so the row of drawing cross section slowly increases from the low order end to the high order end accordingly, formed the oblique angle form, so just saved the copper bar consumption.
Advantage of the present utility model:
1. the design that is flexible coupling of exposing coil can, exposing after the complete low-voltage coil of coiling in the partially folded space that is placed between narrow and small high-low pressure of the row of drawing of low-voltage coil, guarantee coil coiling smoothly.
2. connect rotund characteristics according to three-dimensional winding iron core iron core external diameter, the copper bar radian design of drawing part in the winding displacement circle well is dissolved in coil the row of drawing, and has guaranteed coil dimension.
3. draw the oblique angle design of part in the winding displacement circle, in the situation that meet low-tension current, the copper bar consumption is saved in the cross section requirement of copper bar as far as possible, reduce production costs.

Fig. 2 is the A-A view of Fig. 1.
Embodiment
A kind of three-dimensional coiled core dry-type paper tinsel described in the utility model is drawn row around low-voltage coil, in Fig. 1, this draw package draw together be arranged on the low-voltage coil outside be flexible coupling 1 and be welded on the radian oblique angle copper bar 2 of the end that is flexible coupling, this is flexible coupling in the folding space that is placed between high-tension coil and low-voltage coil; Radian oblique angle copper bar has inside crooked radian, and crooked radian is concentric with coiling internal mold and iron core, and identical with coiling coiling internal mold radian; The height of radian oblique angle copper bar is that oblique angle increases and at highest point, is connected with being flexible coupling to near-end by the distance far-end that is flexible coupling.
Radian oblique angle copper bar is the oblique triangle with radian, and paper tinsel material 3 is welded on the hypotenuse of oblique triangle.The height that is flexible coupling is identical with the maximum height of radian oblique angle copper bar.
In the present embodiment, expose the coiler part employing and be flexible coupling 1, consider after the complete low-voltage coil of coiling on iron core, also need coiling high-tension coil on low-voltage coil, expose the low-voltage coil copper bar and need to fold in the space that is placed between narrow and small high-low pressure, so adopted the design that is flexible coupling.
Draw winding displacement circle inside and be divided into radian oblique angle copper bar 2.Copper bar is with the radian that curves inwardly, and as shown in Figure 2, crooked radian is concentric with coiling internal mold and iron core, well is dissolved into during coiling in low-voltage coil, does not take redundant space, has guaranteed the size of low-voltage coil.Because low-tension current is delivered in the row of drawing through Copper Foil, flow out from the row's of drawing high order end terminal finally, this section copper bar and Copper Foil welding, electric current is to be pooled to high order end from the low order end of paper tinsel material, slowly increase from the low order end to the high order end from the electric current of drawing drainage, so the row of drawing cross section slowly increases from the low order end to the high order end accordingly, formed the oblique angle form, so just saved the copper bar consumption.
The utility model has guaranteed coil dimension, and coil winding is convenient, in the situation that meet low-tension current, the copper bar consumption has been saved in the cross section requirement of copper bar as far as possible, reduces production costs.
