Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of winding an induction electric device used at high voltage.

Conventionally, a disk winding as shown in FIG. 1 has been proposed as an induction electric device winding used at high voltage, such as a high voltage winding of a transformer.

In FIG. 1, the left side of the drawing is the inner peripheral side of the winding, and each rectangular portion represents a cross section of one turn of the conductor. The number attached to the cross section of each conductor in the figure indicates the turn number of that conductor, and the numbered winding without a dash indicates the winding of the first conductor. The windings numbered with . . . indicate windings of the second conductor. In addition, AI indicates a disk winding with the first conductor wound so that the winding start is located on the outer circumference side,
BI is the first winding that is wound so that the beginning of winding is located on the inner circumferential side.
shows a disk winding with a conductor. In the same machine, A2 indicates a disk winding with a second conductor wound so that the winding start is located on the outer circumferential side, and B2 indicates a second disk winding with a winding start located on the inner circumferential side. A disk winding of a conductor is shown. Moreover, S is a shield ring for electric field relaxation arranged at both ends of the winding. As is clear from FIG. 1, this winding consists of disk windings AI, B1, AI of the first conductor
, B1, . . . and disk windings B2, A2 of the second conductor.
, B2, A2, . are connected in parallel with each other. According to such a winding structure, it is possible to improve the potential distribution against surges entering from the outside, improve shock resistance characteristics, and also reduce the burden voltage between each winding. However, conventionally, when winding the above-mentioned horizontal winding wire, it is necessary to repeatedly cut and connect the wound conductor during winding, which increases the number of manufacturing steps, and requires However, it is an object of the present invention to propose a method for winding an induction electric device, which allows the above-mentioned winding to be continuously wound.

The winding method of the present invention will be explained in detail below with reference to FIGS. 2a to 2f.

In FIGS. 2a to 2f, m is a winding frame; d, and Q are first and second conductor supply drums, respectively, on which the wire-wound conductors 1 and 1 are wound; These are drum shafts that rotatably and slidably support conductor supply drums d and Q, respectively.Drum shafts x and & extend in a direction parallel to the axial direction of the winding frame m, and are usually located behind the winding operator. Although the number of turns of each disc winding is arbitrary, in the following explanation, it is assumed that each disc winding is wound with 5 turns as in the example shown in FIG. It is assumed that the disk winding is sequentially formed from the left to the right in Fig. 2.In the first step of the winding method of the present invention, first, as shown in Fig. 2a, the first conductor is Paying out the first conductor 1 from the supply drum d,
While rotating the winding frame m, the conductor 1 is wound into a disk shape for 5 turns to form a temporary winding BI'.

In the figure, la indicates the winding start end of the first conductor 1. Next, this temporary winding wire BI' is unwound, so that the winding start is located on the outer circumferential side, that is, it is wound from the outer circumferential side to the inner circumferential side. The side conductors are exchanged to change the arrangement order of the conductors in the vertical direction. After changing the arrangement order of the conductors, tighten conductor 1 and see Figure 2b.
A disk winding AI is formed in which the winding start is located on the outer circumferential side as shown in FIG. Also, after unwinding the preliminary winding BI' and before forming the disk winding AI, the tip roller a of the second conductor RO, which is fed out from the second conductor supply drum, is placed inside the disk winding AI. It is inserted between the circumferential surface and the winding frame m, and the tip of this conductor B is made to protrude in all directions of the winding axis from between the inner circumference of the disc winding AI and the winding frame m. Next, in the second step, a second conductor 0 is placed adjacent to the right side of the disk winding AI of the first conductor 1 wound in the first step, and this conductor 0 is wound in the circumferential direction of the winding frame. The first conductor 1 is placed at a predetermined distance on the right side of this second conductor, and this conductor 1 is bent in the circumferential direction of the winding frame m to simultaneously connect both conductors. By winding a predetermined number of turns (5 turns in the illustrated example), disc windings B2 and BI whose winding starts are located on the inner circumferential side are formed by the second conductor D and the first conductor 1, respectively.

Next, in the third step, the first conductor 1 and the second conductor are exchanged by swapping the positions of the conductor supply drum d and the left and right parts.
The positions of conductor 0 and conductor 0 are exchanged in the axial direction of the winding, and both conductors are crossed so that the second conductor 0 is located closer to the central axis of the winding frame m.

Next, as shown in FIG. 2d, on the side of the disk winding BI made of the first conductor wound in the second step,
By simultaneously winding both conductors in a disc shape with a predetermined number of turns with the conductor 1 on the left side and the second conductor 0 on the right side, a temporary winding B is created.
I and B2' are formed respectively. In the fourth step, first, the temporary windings BI' and B2' formed in the third step are unwound, and then the second conductor with the curls is connected to the first conductor with the same curls. The positions of both conductors are exchanged through the inside of the conductor 1, and the second conductor 0 with the curl is moved to a position adjacent to the disk winding BI of the first conductor formed in the second step.

At this position, the arrangement order of the second conductor with the winding pattern is changed in the radial direction so that the winding start is located on the outer circumferential side, and then the second conductor is tightened to form the second conductor as shown in Fig. 2e.
A disk winding A2 is formed by the conductor. Furthermore, the tentative winding wire BI' made of the unwound first conductor is moved to a position on the right side of the disk winding A2 made of the second conductor a predetermined distance apart, and the winding start is positioned on the outer circumferential side. By changing the arrangement order of the first conductor with the winding pattern to the lighter direction, a disk winding AI of the first conductor is obtained as shown in Figure 2.
form. The state after the fourth step is completed is shown in Figure 2b.
The condition is the same as that of the aircraft.

Therefore, by repeating the second to fourth steps (FIG. 2 c to f), a wire as shown in FIG. 1 can be wound. After winding all the disk windings, the disk winding group of the first conductor and the disk winding group of the second conductor are connected in parallel to complete the winding. In the above explanation, in order to exchange the positions of the first conductor 1 and the second conductor □ in the third step, the positions of the conductor supply drum d and the conductor were exchanged. They may be replaced. Furthermore, in the above embodiment, the disc windings AI and B2, BI and A2, AI and B2,...
・are arranged in pairs and close to each other, but B2
and B1, A2 and A1, B2 and B1, etc. may be arranged in pairs and close to each other, and the disc windings A1, B2, B1, A2, ... may be arranged at intervals, respectively. It may also be arranged in a raised position.

As described above, according to the present invention, all the disk windings can be wound without cutting the wound conductors by switching the positions of the first and second conductors in the direction of the winding axis during winding. Therefore, the number of winding steps can be reduced, and the winding work time can be shortened. Furthermore, since there are no connection points in the winding, it is possible to prevent the outer dimensions of the winding from increasing and to improve the reliability of the winding. In the above explanation, the first and second conductors are each a single conductor, but
A transition conductor consisting of a plurality of conductors can also be used as each conductor.
