Description

Lead arrangement method, three-spiral coil winding method and transformer

Technical Field

The invention belongs to the technical field of transformer manufacturing, and particularly relates to a lead arrangement method, a three-spiral coil winding method and a transformer.

Background

The spiral coil is a winding form which can be used for medium and large-sized transformers and under the working conditions of low voltage and large current. The spiral coil is formed by winding one or more rows of conducting wires in parallel. One column of wire is wound to form what is referred to as a single helical coil and two columns of wire are wound to form what is referred to as a double helical coil. In practical application, even-numbered columns of conducting wires are generally adopted for winding, such as two columns or four columns. But sometimes due to limitations of factors such as the number of winding turns, axial and radial dimensions, etc., or to achieve some better effect, a triple-spiral coil has to be used, i.e. a parallel winding of three wires.

In the winding process of the coil, each row of the three rows of the conducting wires is formed by stacking a plurality of conducting wires. In order to ensure that the lengths of the wires are equal and the sum of the leakage induction potentials generated at the positions of the leakage magnetic fields is equal, the wires need to be transposed in the winding process. Even-numbered lines are simpler, and two lines can be exchanged, but the three spiral coils relate to the third line, so that the complexity of conductor transposition is increased sharply. If three rows of wires are wound according to the flat cable like the even rows of wires, the wires are wound after multiple transposition, and the wires cannot be wound continuously.

s7, after winding, the first wire row 71, the second wire row 72, and the third wire row 73 are led to the winding die 52 to wind the triple-helical coil.

The following is a detailed description of the wire arrangement method provided by the present invention, which can eliminate the possible winding of the wire during the winding of the coil by the twisting of the wire.

First, a wire transposition method in winding a triple-spiral coil will be described with reference to fig. 3. The method can be found in a general transformer design manual, and belongs to the prior art. Fig. 3 shows a three-spiral coil wound by 12 parallel wires, wherein squares represent the cross section of the wires, the numbers in the squares are the wire serial numbers, one number represents one wire, the numbers outside the squares represent the number of turns, and 0 turn represents the starting position; each turn has three columns of squares representing three columns of wires, for example, the No. 1, No. 2, No. 3, No. 4 wires in the 0 turn form one column, similarly, the No. 5, No. 6, No. 7, No. 8 wires form one column, and the No. 9, No. 10, No. 11, No. 12 wires form one column. In practical applications, a horizontal winding device is generally used, the axis of the winding mold 52 is arranged horizontally, in fig. 3, the left-right direction is the axial direction of the coil, the up-down direction is the radial direction of the coil, also called radial direction, and four wires in the same column are arranged with the lowest layer at the inner diameter side and the highest layer at the outer diameter side. A structure of a column of conductors is also referred to as a cake.

When the number of the parallel-connected wires is an integral multiple of 6, one-time equidistant complete transposition is generally adopted, and the transposition mode is eight-character cross transposition, as shown in fig. 3. For convenience of description, the left column of wires in the same turn is called a left wire cake, the middle column of wires is called a middle wire cake, and the right column of wires is called a right wire cake. After starting the winding, the first transposition occurs on the left and middle cakes of 1 turn: the No. 1 conducting wire on the uppermost layer of the left side wire cake is transposed to the uppermost layer of the middle wire cake, and the transposition process is represented by an arc arrow at the middle upper part of 1 turn; and simultaneously, the No. 8 conducting wire at the lowest layer of the middle wire cake is transposed to the lowest layer of the left wire cake, and the transposition process is represented by an arc arrow at the lower part in 1 turn. The second transposition occurs between the middle cake and the right cake of 2 turns: the No. 9 conducting wire on the uppermost layer of the right wire cake is transposed to the uppermost layer of the middle wire cake, and the transposition process is represented by an arc arrow at the upper middle part of 2; meanwhile, the No. 7 conducting wire at the lowest layer of the middle wire cake is transposed to the lowest layer of the right wire cake, and the transposition process is represented by an arc arrow at the lower part in 2 turns. And finishing equidistant complete transposition by taking the sequence as the order.

It should be noted that the arc-shaped arrow in fig. 3 can reflect the moving direction of the wire during the wire transposition. For example, when the No. 8 conducting wire at the lowest layer of the middle wire cake is transposed to the lowest layer of the left wire cake in 1 turn, the No. 8 conducting wire moves clockwise when viewed from the direction vertical to the paper surface according to the direction shown by the lower arc arrow. In the same way, the arc arrow at the upper part in the 1 turn indicates that the No. 1 conducting wire at the uppermost layer of the wire cake on the left side moves clockwise, the arc arrow at the upper part in the 2 turn indicates that the No. 9 conducting wire at the uppermost layer of the wire cake on the right side moves anticlockwise, and the arc arrow at the lower part in the 2 turn indicates that the No. 7 conducting wire at the lowermost layer of the middle wire cake moves anticlockwise.

Next, the method of twisting the conductive wire described in step S2 will be described with reference to fig. 4, where fig. 4 shows the counterclockwise twisting process of the conductive wire. For a more clear illustration, N is set to 4 in fig. 4. Each box in fig. 4 represents a wire cross-section and the numbers within the boxes represent wire numbers. Note that fig. 4 does not relate to the conductor numbers in fig. 1.

For convenience of description, the five-column squares in fig. 4 are named as a first column, a second column, a third column, a fourth column and a fifth column from left to right. In step S2, when N is 4, the four wires in the left row 61 are aligned in a vertical row to form a wire row shown in the first row, and the wires are in a straightened state and are not twisted with each other. After twisting and winding are started, in a first step, as shown in a second row, the No. 1 conducting wire at the uppermost layer moves from the left side of the conducting wire row to the lowermost layer from top to bottom anticlockwise according to a path shown by an arc arrow, and the No. 2 conducting wire is located at the uppermost layer; secondly, as shown in the third row, moving the No. 2 conducting wire at the uppermost layer from the left side of the conducting wire row to the lowermost layer from the left side of the conducting wire row to the uppermost layer at the moment, wherein the No. 3 conducting wire is positioned at the uppermost layer, according to the path shown by the arc arrow and anticlockwise from top to bottom like the No. 1 conducting wire; and thirdly, similarly moving the No. 3 conducting wire at the uppermost layer to the lowermost layer to form a first sub-column shown in a fifth column as shown in a fourth column. The wires are continuous wires, one end of each wire is wound on the wire wheel 51, and the other end of each wire is wound on the winding mold 52, so that when the first step to the third step are carried out, the wires on the uppermost layer are wound with the other three wires in the process of moving to the lowermost layer, and the reverse twisting is realized.

Fig. 4 shows the counterclockwise twisted wire, when the twisted wire is twisted clockwise, the uppermost wire moves clockwise from top to bottom from the right side of the wire row to the lowermost wire.

Finally, with reference to fig. 3 and 5, it is explained why the wire arrangement method provided by the present invention can eliminate the winding that may occur due to wire transposition when winding a coil by twisting the wire. When N is 2 and the direction of the wire shift in step S3 is counterclockwise, the first wire column 71, the second wire column 72, and the third wire column 73 in step S7 may be represented by fig. 5. In fig. 5, squares represent the cross-section of a wire, the numbers in the squares represent the wire numbers, and the curved arrows in the squares indicate the direction of shifting of the wire. The No. 1 conductive line and the No. 2 conductive line in the third conductive line column 73 are the second subcolumn, and the No. 3 conductive line and the No. 4 conductive line are the first subcolumn, all formed in step S3. The No. 9 conductive line and the No. 10 conductive line in the first conductive line column 71 are the fourth subcolumn, and the No. 11 conductive line and the No. 12 conductive line are the third subcolumn, all formed in step S4. The conductive lines in the second conductive line array 72 are formed by alternately stacking conductive lines in a fifth subcolumn and a sixth subcolumn, the conductive line No. 8 is the lowermost conductive line in the fifth subcolumn, the conductive line No. 7 is the lowermost conductive line in the sixth subcolumn, the conductive line No. 6 is the inner penultimate conductive line (indicating the original position) in the fifth subcolumn, and the conductive line No. 5 is the inner penultimate conductive line (indicating the original position) in the sixth subcolumn.

In step S3, the direction of the wire shift is counterclockwise, so in fig. 5, all the squares of the third wire row 73 are counterclockwise arrows; similarly, the squares of the first wire row 71 are clockwise arrows, and the counterclockwise and clockwise arrows of the second wire row 72 are alternately shown.

The transposition shown in fig. 3 is performed using the three columns of conductors shown in fig. 5. For ease of viewing, the conductors at the same locations in fig. 5 and 3 are provided with the same reference numbers. Comparing the 12 wires in fig. 5 with the 12 wires with 0 turns in fig. 3, it can be seen that the transposition indicated by the curved arrow below 1 turn in fig. 3 corresponds to the transposition of wire No. 8 in the second wire column 72 to the lowest layer of the third wire column 73 in fig. 5, the curved arrow below 1 turn in fig. 3 is counterclockwise, and the curved arrow inside wire No. 8 in fig. 5 is clockwise. That is, the wire 8 in fig. 5 twisted in the opposite direction just can counteract the winding of the wire caused by the counterclockwise transposition represented by the curved arrow below the 1 turn in fig. 3. Similarly, wire number 1 in the third wire column 73 in fig. 5 can counteract the twisting of the wire caused by the clockwise shift represented by the curved arrow above the 1 turn in fig. 3. By analogy, each reversely twisted wire in fig. 5 can counteract the wire winding caused by the transposition indicated by the corresponding arc arrow in fig. 3, so that the parallel wires can still keep the ordered arrangement among the wires after multiple times of cross transposition, mutual winding cannot occur, and the smooth winding of the triple-spiral coil can be ensured.

It should be noted that, as specified in the design manual, the first transposition on the inner diameter side is generally the transposition of the second wire row 72 to the third wire row 73, i.e., the transposition indicated by the curved arrow below 1 turn in fig. 3. The wire arrangement method of the present application is derived based on the above-mentioned specifications. Even if the actual situation does not conform to the design manual, the skilled person can easily derive the modified lead arrangement method according to the idea provided by the present invention, and the methods are all within the protection scope of the present application.

As a specific embodiment of the wire arranging method provided by the present invention, when the triple-helical coil is in the left winding direction, the wire shift direction in step S3 is counterclockwise, and when the triple-helical coil is in the right winding direction, the wire shift direction in step S3 is clockwise, that is, the wire shift and twisting directions need to be determined according to the winding direction of the triple-helical coil to be wound, so as to ensure that the twisting direction is correct, and the wire winding caused by transposition can be cancelled.

As an embodiment of the method for arranging the wires according to the present invention, referring to fig. 1 and 2, the left column 61, the middle column 62 and the right column 63 are linearly arranged and linearly arranged, and the arrangement direction is parallel to the axis of the winding mold 52. So that the wire can be conveniently led from the reel 51 to the winding die 52.

As an embodiment of the method for arranging wires according to the present invention, referring to fig. 1 and 2, the wire wheels 51 in each row are linearly arranged in a direction perpendicular to the arrangement direction of the left column 61, the middle column 62, and the right column 63. The arrangement mode of the wire wheel 51 is beneficial to reducing the occupied space of the wire wheel 51 and improving the space utilization rate. Especially, when the numerical value of N is larger, the flat cable and the winding wire can be ensured not to occupy too large space.

Referring to fig. 2, a reel 51 is disposed on a lead frame 53, and a caster is disposed at the bottom of the lead frame 53 and can move parallel to the axial direction of a winding mold 52. As the wire is wound, the winding position moves along the axial direction of the winding mold 52, and the movable lead frame 53 can be adapted to the movement of the winding position. Specifically, the lead frame 53 may be moved by manual driving or may be moved automatically.

As a specific implementation manner of the wire arrangement method provided by the present invention, the wire is a flat wire made of a metal material. Specifically, the conducting wire is a flat copper wire or a flat aluminum wire.

As a specific embodiment of the wire arrangement method provided by the present invention, the first wire row 71, the second wire row 72, and the third wire row 73 are separated from each other by a wire clamp, so that it is ensured that wires in three rows are not mixed up, which is beneficial to improving the winding efficiency. Specifically, the wire clamp is of an n-shaped structure with a downward opening, the width of the opening of the wire clamp is the same as that of the wire, the wire can be effectively constrained into a line, the wire clamp is taken down after the wire is transposed, and the wire clamp is inserted after the transposition is completed.

The invention also provides a winding method of the triple-spiral coil, which arranges the wires by the wire arrangement method before the wires are wound, so that the parallel wires can still keep the orderly arrangement of the wires after multiple cross transposition, mutual winding can not occur, the smooth winding of the triple-spiral coil can be ensured, and the winding efficiency is high and the quality is good.

Fig. 5 is a schematic perspective view of a three-spiral coil during winding. During winding, eight-character cross transposition is adopted, the wire at the uppermost layer of the third wire row 73 is firstly transposed to the uppermost layer of the second wire row 72, namely, the bright position 81, and the wire at the lowermost layer of the second wire row 72 is transposed to the lowermost layer of the third wire row 73, namely, the bottom position 82, in the interval from the next stay 521 (according to the coil development diagram). And then in the interval of the next stay 521, the topmost wire of the first wire row 71 is replaced by the second wire row 72, in the interval of the next stay 521, the last wire (which is the original position) at the lower layer of the second wire row 72 is replaced by the first wire row 71, and the rest is repeated to finish all the replacement.

The invention also provides a transformer which comprises the three-spiral coil, wherein the three-spiral coil is wound by the winding method of the three-spiral coil, so that the three-spiral coil can be smoothly wound, and the production efficiency and the product quality of the transformer are improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
