点があつた。(Prior art) For armature windings of rotating electric machines and secondary windings of induction machines, two-layer windings in which upper and lower coils are inserted in the same slot are often adopted. A single-layer winding with one coil per slot is sometimes used because of its advantages such as a good space factor and a reduction in the number of coils. As with the two-layer winding, the connection means for the single-layer winding is generally a connection in which a coil 15 is lap-wound or wave-wound around the iron core 10 as shown in FIG. 6 or 7. By the way, in any of the above connection means, in order to connect the upper coil and the lower coil in sequence, the 9th coil is connected at the coil end.
As shown in the figure, it is necessary to provide an inclined portion 17. The distance δ between the coils in the inclined portion 17 is determined from the voltage of the rotating electric machine in order to prevent corona discharge between the coils, and the higher the voltage, the wider the minimum spatial distance required for insulation. Here, δ can be increased by extending the length of the coil inclined portion 13 in the axial direction. However, in such cases, in high-voltage machines, the axial length C of the coil inclined portion 17 may have to be made extremely large in order to increase δ. It becomes impossible to support the coil end with the machine's secondary winding, etc., making the machine unusable, and even when used on the stator side, a large space must be provided for the coil end. However, there were drawbacks such as the need to increase the size of the machine. Conversely, if there are restrictions on the installation location of the rotating electrical machine, single-layer windings have better conditions than double-layer windings, but the minimum space distance required for insulation is This caused the inconvenience that it may not be possible to secure it. As one means for solving this drawback, a chain-wound connection as shown in FIG. 8 is generally known for single-layer windings. In the case of chain-wound connection, since the coils are connected in order from the adjacent coils between adjacent phase bands of the same phase, the distance δ 0 between the coils at the transition portion of the coil ends can be set arbitrarily as shown in Fig. 2 according to the present invention. This is advantageous when it is necessary to widen the insulation space between coils in a high-voltage machine. However, in this case, there are many different coil shapes (at least twice as many types as the number of slots per pole (hereinafter referred to as TA) of the rotating electrical machine, and twice as many types in the case of one-turn coils). , coils become incompatible, the number of spare coils increases, and coils come in a wide variety of shapes, so productivity is poor compared to coils of other shapes, and manufacturing costs increase. It was hot.

(Means for solving the problem) In order to achieve the above purpose, in this invention,
The shape of the end part of a coil with one conductor in one slot is an upper coil with straight parts extended at both ends, a lower coil with both ends bent downward from the upper coil, and one end shaped like an upper coil and the other end shaped like a lower coil. There are three types of coils, upper and lower coils, and the bending direction of the tip of each coil end is reversed around the direction of the straight part of the coil, and a predetermined space between the coils is maintained at the coil end for each type of coil. As shown in the figure, coils of the same shape are arranged with their positions shifted in the axial direction within a single phase band, and the connection of coils between adjacent phase bands of the same phase is performed using crossover wires connected at both ends in the same manner as chain winding. A single-layer winding for a rotating electric machine is provided.

In a device configured in this way, the connection means of the coil end portion is equivalent to a chain winding when looking at each end of the core, so even in a limited space, the distance between the coils at the crossover wire portion of the coil end portion can be adjusted. This makes it possible to make the coils wider, and even in high-voltage rotating electric machines, it is possible to secure a sufficient insulating space distance between the coils. In addition, there are three types of coil shapes, and there are two types of coil end shapes, an upper coil shape and a lower coil shape, so the manufacturing of the coil is simplified compared to chain winding, and conventional lap winding and coil winding. It is equivalent to a single-layer wave-wound coil, and the number of spare coils is significantly reduced compared to conventional chain-wound coils.

す。(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4. In Figure 1,
1 is a lower coil, 2 is an upper coil, and 3 is a coil in which one end of the coil end is an upper coil, and the remaining end is a lower coil (hereinafter referred to as the upper and lower coil). If you reverse them, they are the same, so in the end, the lower coil 1, upper coil 2,
There are three types of shapes for the upper and lower coils 3. A phase zone division line 10a in the iron core 10 clearly distinguishes the phase zones. Each of the coils 1, 2, and 3 is arranged such that the bending direction of the coil end transition portion 5 is reversed with respect to the direction of the straight coil portion, and the coils are aligned so that a predetermined mutual phase space between the coils is maintained at the coil end portion for each type of coil. Coils of the same shape are arranged with their positions shifted in the axial direction within a phase band, and the coils between adjacent phase bands of the same phase are connected by crossover wires 4 similarly to chain winding. 6 is a connection part. FIGS. 2 and 3 show the structure of the coil end portion when each coil 1, 2, 3 is inserted into the slot. The second coil and the connecting wire 4 are shaded with diagonal lines, but this is to make the division clear and is not a cross-sectional representation.
In FIG. 2, the connecting wires 4 of the upper coil 2 are arranged in the order of 2A, 2B, 2C, and 2D from the core end side while maintaining the required insulation space distance δ 0 between the coils. Upper coil 2 is 2A, 2B, 2C, 2D
In both cases, the coils of the same shape are inserted shifted in the axial direction, so at the end of the core opposite to the end of the core shown in FIG .
They will be lined up in the order of 2B and 2A. In addition, 11 is an outer spacer piece, 12 is a presser plate, and 13 is a slot.

を満足しない事になる。この解決策を第２図及び
第４図を使用して説明する。 By the way, the coils used in Figures 1, 2, and 3 are one-turn coils, but as mentioned above, they are inserted with the axial direction shifted relative to the insertion slot, so there is a 360-turn coil within the core length. ° In the conventional method of performing Lebel dislocation, a portion where Lebel dislocation does not exist occurs within the core length due to the coil, resulting in an increase in stray loss. Also, the Lebel dislocation position is determined depending on the location of use for each coil. If they were shifted, the conditions for coil compatibility, which is one of the purposes of the present invention, would not be satisfied. This solution will be explained using FIGS. 2 and 4.

のコイル２Ａに使用すれば一応レーベル転位の目
的を果たせる。 In FIG. 4, the starting point "X" of the Lebel dislocation in the straight section of the coil is assumed to be the core end surface position "X 0 " of the coil 2A where the crossover wire 4 shown in FIG. 2 is closest to the core end. The coil is subjected to 360° Lebel transposition within the core length l at a predetermined dislocation pitch γ starting at position X corresponding to the core end surface I can accomplish it.

転位を行なう。尚、もし（Ｎ＋ｎ）γ＞（ｌ＋α）
となる場合は第４図のレーベル転位始点位置
“Ｘ”を更に渡り線部側にずらしても構わない。 The Lebel dislocation pitch γ is given by γ=l/N (101), where N is the number of wires in the coil. By the way, when only 360 degrees of Lebel dislocation is used in coils 2B, 2C, and 2D in Fig. 2, the starting point of Lebel dislocation will be outside the core, and the range of Lebel dislocation will not span the entire length inside the core, so the fourth As shown in the figure, coils 2A and 2 in Figure 2 are further from the end point "Y" of the 360° Lebel transposition.
The Lebel transposition range is extended beyond the distance α between D and the transposition is performed to the extension end point “Z” so that nγ≧α (102) (n is an integer). As a result, regardless of whether the coil shown in FIG. 4 is used as any of the coils 2A, 2B, 2C, and 2D in FIG. 2, the Lebel dislocation will always be 360° over the entire length within the core. Although the upper coil was explained in FIGS. 2 and 4, the lower coil 1 in FIG.
The upper coil 3 is also subjected to Lebel transposition using exactly the same method. Furthermore, if (N+n)γ>(l+α)
In this case, the Label dislocation starting point position "X" in FIG. 4 may be further shifted toward the crossover section.

となる可能性がある。この点については以下に説
明する手段にて解決できる。 Next, in FIG. 1, the order of insertion of the coils will be considered. It is obvious that the lower coil 1 should be inserted first and the upper coil 2 last, but no matter which of the upper and lower coils 3 is inserted after the lower coil 1, the transition part 5 will get in the way and it will be difficult to insert the upper coil 3 later. If you insert it, you may not be able to insert it, and you may need to use a fried coil or a buoyancy coil. This point can be solved by the means described below.

The upper and lower coils 3 are placed behind the transition part 5 of
The upper and lower coils 3 can be carried to a predetermined slot position while being shifted through the transition portion 5 of the lower coil-shaped L portion. In addition, the coils 2A, 2B, 2 in Fig. 2
The required length of the transition section 5 of C and 2D varies depending on the coil, but it can be manufactured at the longest length and then cut at the time of assembly, or the coils can be connected using a copper strip. 2A, 2B, 2C, 2
D is a coil having the same shape including the transition portion 5.
Further, the coils may be connected to each other by a connecting copper band 14 at the lead-out portion of the "S" section in FIG.

According to the configuration as described above, the distance δ 0 between the connecting wires 4 at the coil end portions can be freely selected. In addition, in addition to two types of coil end parts, each with the same shape, upper coil shape 2 shape and lower coil shape 1 shape, the coil has upper coil shape U at one end and lower coil shape L at the other end. There are a total of three types including coils. Furthermore, by appropriately manufacturing the interval between the transition portions 5 between the upper coil 2 and the lower coil 1 and connecting each coil with the crossover wire 4, there is no need for lifting coil work or floating coil work during winding assembly.

る。 In this way, the spatial distance between the coils at the coil ends can be widened, increasing the insulation strength between the coils, reducing the risk of corona discharge and flashover, and improving the reliability of rotating electrical machines. will improve. In addition, since there are fewer types of coils, coil compatibility is increased and the need for spare coils is reduced, and productivity in coil manufacturing is also improved compared to conventional chain-wound coils, which can be done at the same level as lap-wound or wave-wound coils. Furthermore, since there is no need to lift the coil, the coil insulation will not be damaged during winding assembly, and the reliability of the rotating electric machine is ensured from this point of view as well.
