All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and fig. 2, fig. 1 is a flow chart illustrating a method for manufacturing a continuous winding transformer coil with 6 parallel wound wires according to the present invention; fig. 2 is a schematic diagram of a 6-wire transposition.
The invention provides a method for manufacturing a continuous winding transformer coil with 6 parallel wound wires, which comprises the following steps:
s1, transposition is carried out between the 6n +2a +1 th section and the 6n +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 2;
in a 6-wire parallel-wound continuous winding, the number of segments of the wire is usually an integer multiple of 6, that is, the winding has 6 integral multiple of wire cakes, each wire cake has 6 wire positions arranged in sequence, and the 6 wire positions are respectively used for accommodating 6 wires. Usually, every 6 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, second, third, fourth, fifth and sixth wires 1, 2, 3, 4, 5 and 6 are wound in the 1 st, 2 nd, 3 rd, 4 th, 5 th and 6 th wire positions of the 1 st segment 101, respectively. As shown in fig. 2, the 1 st segment 101 is wound with 6 wires from the right to the left in 6 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 2, namely the corresponding line cakes are transposed by adopting the standard transposition method when a is 0, 1 and 2.
Optionally, the standard transposition method is to transpose the wires in the previous section of 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 and the 6 th wire position to the 6 th wire position, the 5 th wire position, the 4 th wire position, the 3 rd wire position, the 2 nd wire position and the 1 st wire position of the subsequent section respectively. Taking the transposition between the 1 st segment 101 and the 2 nd segment 102 as an example, the 6 wires are the first wire 1, the second wire 2, the third wire 3, the fourth wire 4, the fifth wire 5 and the sixth wire 6 in the order of 5 wire positions of the 1 st segment 101. After transposition, the 6 wires are the sixth wire 6, the fifth wire 5, the fourth wire 4, the third wire 3, the second wire 2 and the first wire 1 in the sequence of 5 wire positions of the 2 nd section 102.
S2, performing transposition between the 6n +2 th section and the 6n +3 th section by adopting a first packet transposition method;
s3, transposition is carried out between the 6n +4 th section and the 6n +5 th section by adopting a second grouping transposition method;
the first grouping transposition method and the second grouping transposition method divide 6 wires in the 6 wire positions in the previous section into two wire groups, and the wires in each wire group are continuously distributed in the previous section. The first 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 first wire group, and divides the wires in the 5 th wire position and the 6 th wire position into a second wire group. And in the transposition process, the sequence of the wires in the same wire group is kept unchanged, and only the positions of the first wire group and the second wire group are exchanged. The second grouping transposition method divides the wires in the 1 st wire position and the 2 nd wire position in the previous section into a third wire group, and divides the wires in the 3 rd wire position, the 4 th wire position, the 5 th wire position and the 6 th wire position into a fourth 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 third wire group and the fourth wire group are only exchanged.
In a specific embodiment of the present application, a first group transposition method is adopted between the 2 nd segment 102 and the 3 rd segment 103, after the exchange, a wire in the 1 st wire position of the previous segment is transposed to the 3 rd wire position of the next segment, a wire in the 2 nd wire position of the previous segment is transposed to the 4 th wire position of the next segment, a wire in the 3 rd wire position of the previous segment is transposed to the 5 th wire position of the next segment, a wire in the 4 th wire position of the previous segment is transposed to the 6 th wire position of the next segment, a wire in the 5 th wire position of the previous segment is transposed to the 1 st wire position of the next segment, and a wire in the 6 th wire position of the previous segment is transposed to the 2 nd wire position of the next segment.
Correspondingly, the 4 th segment 104 and the 5 th segment 105 adopt a second sub-transposition method, after transposition, the wire in the 1 st wire position of the previous segment is transposed to the 4 th wire position of the next segment, the wire in the 2 nd wire position of the previous segment is transposed to the 5 th wire position of the next segment, the wire in the 3 rd wire position of the previous segment is transposed to the 1 st wire position of the next segment, the wire in the 4 th wire position of the previous segment is transposed to the 2 nd wire position of the next segment, the wire in the 5 th wire position of the previous segment is transposed to the 3 rd wire position of the next segment, and the wire in the 6 th wire position of the previous segment is transposed to the 4 th wire position of the next segment.
Of course, the user may also use the second packet transposition method between the 6n +2 th segment and the 6n +3 th segment and the first packet transposition method between the 6n +4 th segment and the 6n +5 th segment as required, which is not limited herein.
And S4, performing transposition between the 6n +6 th section and the 6(n +1) +1 th section by adopting a horizontal drawing transposition method.
There may be two or more pie-sets of 6 wires wound in a continuous winding. The manufacturing 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 mode of the 1 st segment 101 to the 6 th segment 106, so the transposition modes of the 7 th segment 201 to the 12 th segment 206 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 6 th segment 106 and the 7 th segment 201 as an example, the transposition is performed by using a horizontal pulling transposition method, specifically, a wire in the 1 st wire position of the previous segment is transposed to the 1 st wire position of the next segment, a wire in the 2 nd wire position of the previous segment is transposed to the 2 nd wire position of the next segment, a wire in the 3 rd wire position of the previous segment is transposed to the 3 rd wire position of the next segment, a wire in the 4 th wire position of the previous segment is transposed to the 4 th wire position of the next segment, a wire in the 5 th wire position of the previous segment is transposed to the 5 th wire position of the next segment, and a wire in the 6 th wire position of the previous segment is transposed to the 6 th wire position of the next segment.
According to the manufacturing method of the continuous winding transformer coil with 6 conducting wires wound in parallel, as shown in fig. 2, the times of occurrence of each conducting wire in the same wire position after transposition are the same, the length of each conducting wire, the resistance of each conducting wire and the induced electromotive force of magnetic leakage are equal, circulating current generated among the conducting wires is avoided, and load loss of a transformer is reduced.
