Abstract

The utility model discloses an inter screen transposed conductor, which is constituted by a plurality of enameled flat copper wires forming two wide rows contacting with each other, which is characterized in that the upper and lower surface of the enameled flat copper wires conducts transposition in the same rotating direction along the narrow surfaces; the traditional partition paper can be replaced by one or more shielded wires vertically disposed between the two rows of the enameled flat copper wires; a magnet wire is formed by coiling the electrician insulated paper tape or net belt. By adopting the novel structure that the shielded wires is directly forged into the transposed conductor, on one hand, the utility model has advantages of guaranteeing the insulation properties, reducing the insulation winding thickness of the shielded wires, reducing the radial size of the coil, saving the raw material costs of the transformer, reducing the weight of the transformer, on the other hand, the structure of coiling the transposed conductor and the shielded wires together can be changed into the coil structure directly, which can facilitate the operation, simply the technique, save the coiling time, and improve the production efficiency. The utility model is mainly used for producing the windings of the large-scale oil immersion-type electric transformer and electric reactor.

Description

Inner screen transposition wire

Technical field

The utility model relates to a kind of inner screen transposition wire, and particularly a kind of little inner screen transposition wire that takes up room is mainly used in the winding of making large oil immersed power transformer and reactor etc.

Background technology

Its version of present transformer coil adopts transposed conductor to add the mode that shielding conductor carries out coiling mostly, therefore require the insulation thickness of shielding conductor thicker, and its structure is unreasonable, not only takes up room greatly but also waste raw material, and is simultaneously also more loaded down with trivial details on technology.

Summary of the invention

The purpose of this utility model is for remedying the deficiencies in the prior art, has rational in infrastructurely and provide a kind of, and little novel inner screen transposition wire takes up room.For achieving the above object, the utility model adopts following technical proposals: inner screen transposition wire, it is to be combined into two row that wide face is in contact with one another by many enameling copper strap wires, on two row enameling copper strap wires and below do the same transposition that turns to along leptoprosopy, and at the traditional middle lining paper of one or more shielding conductor replacement of the vertical arrangement in the centre of two row enameling copper strap wires, then with wrapped winding wires that forms such as electrician's insulating paper strip or net bands.

The utility model is owing to adopted shielding conductor has directly been made new structure in transposed conductor inside, therefore under the prerequisite that guarantees its insulation property, can reduce the turn insulation thickness of shielding conductor, and then reduce the radial size of coil, save the cost of raw material of transformer, reduced the weight of transformer; On the other hand, after coil adopted inner screen transposition wire, coil added the shielding conductor coiling by original transposed conductor and changes the direct coiling of transposed conductor into, and handled easily has been simplified technology, has saved the coiling time of coil, has improved production efficiency.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

With reference to Fig. 1, inner screen transposition wire, it is to be combined into two row that wide face is in contact with one another by many enameling copper strap wires 1, on two row enameling copper strap wires 1 and below do the same transposition that turns to along leptoprosopy, and at one or more shielding conductor of the vertical arrangement in the centre of two row enameling copper strap wires, and with electrician's insulating paper strip or the net band 2 wrapped winding wires that form.Above-mentioned shielding conductor is to be made of the bare copper flat wire 3 that is surrounded by paper insulation 4.

To operate by specification requirement in the manufacturing process, can make the inner screen transposition wire of various different sizes according to actual needs.

Claims

1. inner screen transposition wire, it is characterized in that: inner screen transposition wire, it is to be combined into two row that wide face is in contact with one another by many enameling copper strap wires (1), on two row enameling copper strap wires (1) and below do the same transposition that turns to along leptoprosopy, and at one or more shielding conductor of the vertical arrangement in the centre of two row enameling copper strap wires, and with electrician's insulating paper strip or the wrapped winding wire that forms of net band (2).

2. inner screen transposition wire as claimed in claim 1 is characterized in that: above-mentioned shielding conductor is to be made of the bare copper flat wire that is surrounded by paper insulation (4) (3).
