Referring to fig. 1 and fig. 2, fig. 1 is a flowchart illustrating a transposition method for winding 8 wires around a continuous winding according to the present invention; fig. 2 is a schematic diagram of an 8-wire transposition.
The invention provides a transposition method for 8 leads wound around a continuous winding, which comprises the following steps:
s1, transposition is carried out between the 8n +2a +1 th section and the 8n +2a +2 th section by adopting a standard transposition method, wherein n is a non-negative integer, and a is an integer which is more than or equal to 0 and less than 4;
in a continuous winding wound around 8 wires, the number of segments of the wire is usually a positive integer multiple of 8, that is, the winding has 8 positive integer multiples of wire cakes, each wire cake has 8 wire positions arranged in sequence, and 8 wire positions are respectively used for accommodating 8 wires. Usually, every 8 sections are a line cake group, and the winding mode adopted by each line cake group is the same, so the application takes a line cake group as an example for illustration.
Optionally, the wire is wound into the wire cake of segment 1 101 before transposition. Thus, the first wire 1, the second wire 2, the third wire 3, the fourth wire 4, the fifth wire 5, the sixth wire 6, the seventh wire 7, and the eighth wire 8 are respectively wound in the 1 st wire position, the 2 nd wire position, the 3 rd wire position, the 4 th wire position, the 5 th wire position, the 6 th wire position, the 7 th wire position, and the 8 th wire position of the 1 st segment 101. As shown in fig. 2, the 1 st segment 101 is wound with 8 wires from the right to the left in 8 wire positions. The boxes in fig. 2 are lines and the numbers in the boxes represent the numbers of the conductive lines.
And (3) performing transposition on the 2a +1 th section and the 2a +2 nd section by adopting a standard transposition method, wherein a is an integer which is more than or equal to 0 and less than 4, namely the corresponding line cakes are transposed by adopting the standard transposition method when a is 0, 1, 2 and 3. The standard transposition method is to transpose a lead in the ith line position of the previous section to the 8-ith line position of the next section, wherein i is an integer larger than 0 and smaller than 8. For example, the conductor in the 2 nd line position of the previous segment is positioned in the 6 th line position of the subsequent segment after transposition.

Taking the transposition between the 1 st segment 101 and the 2 nd segment 102 as an example, the 8 wires are sequentially a first wire 1, a second wire 2, a third wire 3, a fourth wire 4, a fifth wire 5, a sixth wire 6, a seventh wire 7 and an eighth wire 8 in the order of 8 wire positions of the 1 st segment 101. After transposition, the 5 wires in the 5 wire positions of the 2 nd segment 102 are sequentially an eighth wire 8, a seventh wire 7, a sixth wire 6, a fifth wire 5, a fourth wire 4, a third wire 3, a second wire 2 and a first wire 1.
S2, performing transposition between the 8n +4b-2 th section and the 8n +4b-1 th section by adopting a first packet transposition method, wherein b is a number more than 0 and less than 3;
the first grouping transposition method divides 8 leads in the previous section of 8 line positions into four lead groups, each lead group comprises two leads, and the leads in each lead group are continuously distributed in the previous section.

And in the transposition process, the positions of the first lead group and the fourth lead group are exchanged, the positions of the second lead group and the third lead group are exchanged, and the sequence of leads in the same lead group is kept unchanged.

S3, transposition is carried out between the 8n +4 th segment and the 8n +5 th segment by adopting a second grouping transposition method;
the second grouping transposition method divides the wires in the 1 st wire position, the 2 nd wire position, the 3 rd wire position and the 4 th wire position in the previous section into a fifth wire group, and divides the wires in the 5 th wire position, the 6 th wire position, the 7 th wire position and the 8 th wire position into a sixth wire group. And in the transposition process, the sequence of the wires in the same wire group is kept unchanged, and the positions of the fifth wire group and the sixth wire group are only exchanged.
Specifically, the 4 th segment 104 and the 5 th segment 105 adopt a second transposition method, which divides the wires in the 1 st wire position, the 2 nd wire position, the 3 rd wire position and the 4 th wire position of the previous segment into a fifth wire group, and divides the wires in the 5 th wire position, the 6 th wire position, the 7 th wire position and the 8 th wire position of the previous segment into a sixth wire group. And exchanging the positions of the fifth lead group and the sixth lead group by adopting a second transposition method. After transposition, a lead in the 1 st line position of the previous section is transposed to the 5 th line position of the next section, a lead in the 2 nd line position of the previous section is transposed to the 6 th line position of the next section, a lead in the 3 rd line position of the previous section is transposed to the 7 th line position of the next section, a lead in the 4 th line position of the previous section is transposed to the 8 th line position of the next section, a lead in the 5 th line position of the previous section is transposed to the 1 st line position of the next section, a lead in the 6 th line position of the previous section is transposed to the 2 nd line position of the next section, a lead in the 7 th line position of the previous section is transposed to the 3 rd line position of the next section, and a lead in the 8 th line position of the previous section is transposed to the 4 th line position of the next section.

In a continuous winding with 8 wires wound in parallel, there may be two or more coil groups. The transposition method in the above embodiment can realize complete transposition of the wire in one cake group, and each cake group can refer to the transposition modes of the 1 st segment 101 to the 8 th segment 108, so that the transposition modes of the 9 th segment 201 to the 16 th segment 208 and more cake groups are not described herein again. And the wire cake groups can be transposed by adopting a horizontal drawing transposition method, and the horizontal drawing transposition method is specifically to directly transpose the wire from the former section of wire position to the latter section of the same wire position. Taking the 8 th segment 108 and the 9 th segment 201 as an example, the transposition is performed by using a horizontal pulling transposition method, specifically, the wire in the 1 st wire position of the previous segment is transposed to the 1 st wire position of the next segment, the wire in the 2 nd wire position of the previous segment is transposed to the 2 nd wire position of the next segment, the wire in the 3 rd wire position of the previous segment is transposed to the 3 rd wire position of the next segment, the wire in the 4 th wire position of the previous segment is transposed to the 4 th wire position of the next segment, the wire in the 5 th wire position of the previous segment is transposed to the 5 th wire position of the next segment, the wire in the 6 th wire position of the previous segment is transposed to the 6 th wire position of the next segment, the wire in the 7 th wire position of the previous segment is transposed to the 7 th wire position of the next segment, and the wire in the 8 th wire position of the previous segment is transposed to the 8 th wire position of the next segment.
