Bit architecture.
Background technology
With the continuous development of China's T ＆ D Technology, the species of transformer is more and more, and capacity, voltage class also all exist
Step up.According to the design needs, the coil of many transformers all employs width to compound wire.Because transformer coil is in
In stray field, width, so in order to reduce coil eddy-current loss, reduces the average temperature of coil to that can produce circulation between compound wire
Rise and temperature rise of hot spot to width to compound wire, it is necessary to replace, it is approximately zero to make the circulation voltage between its compound wire.
The content of the invention
For problem described above, the present invention provides a kind of transposition structure using width to more compound wire coils.
The identical i.e. transposition in each wire location in stray field can be made complete, it is effective to reduce coil circulation voltage, increase
The range of choice of wire line gauge during coil design, reduce the manufacturing cost of transformer.And it is practical reliable, it is easy to make.
The present invention adopts the following technical scheme that to realize：
A kind of transposition structure using width to more compound wire coils, the transposition structure centered on forming tube, along
The axial direction of forming tube, is wound with some groups of line cakes, and every group of line cake includes n root compound wires；Wherein,
K1 cakes in every group of line cake, it is followed successively by the 1st wire, the 2nd wire, to from the inside to the outside centered on forming tube
N root wires, the k2 cake adjacent with k1 cakes, it is followed successively by n-th wire, (n-1)th wire from the inside to the outside centered on forming tube, extremely
1st wire, by that analogy, in kn cakes, it is followed successively by the 1st wire from the inside to the outside centered on forming tube, the 2nd wire, extremely
N-th wire；N is the positive integer more than 2, and k is positive integer.
Further improve of the invention is that the width of the transposition structure is taken more than n's to more compound wire transposition number N
Integer multiple, wherein, transposition number N calculation formula is as follows：
Wherein, m is total cake number,F is frequency, and I is electric current, and W is coil turn, H
For coil reactance height, S is per the leakage field area of cake wire, UmFor the allowable value of circulation voltage.
The present invention, which further improves, to be, the circulation voltage U of every transposition interval of the transposition structure1、U2、...、Un
Less than allowable value Um, and the circulation voltage of each transposition interval is added and when U is zero, the transformer coil complete transposition.
The present invention has following beneficial technique effect：
A kind of transposition structure using width to more compound wire coils provided by the invention, can leak each wire
Identical complete, the effective reduction coil circulation voltage that replaces in location, wire when increasing coil design in magnetic field
The range of choice of rule, the manufacturing cost of transformer is reduced, and it is practical reliable, it is easy to make.The present invention solves width to more
The incomplete problem of root compound wire transposition, adds range of choice of the coil design to wire line gauge.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram using width to the transposition structure of more compound wire coils.
In figure：1- forming tubes.
Embodiment
The present invention is made further instructions below in conjunction with accompanying drawing.
As shown in figure 1, a kind of transposition structure using width to more compound wire coils provided by the invention, the transposition knot
Structure, along the axial direction of forming tube 1, is wound with some groups of line cakes, it is compound that every group of line cake includes n roots centered on forming tube 1
Wire；Wherein, start to replace during the complete k1 cakes of lower end coiling, width is to most the 1st wire transposition in inner side of n roots compound wire to inner side the
The position of 2 wires, width is to n-th wire transposition of the compound inner side of wire the 2nd to the position of the 3rd wire in inner side, and width is to n-th
N-th wire transposition of the compound outermost of root wire is to most inner side, and compound wire is followed successively by n......1 from inside to outside after transposition, and 2,
3, n-1；Need to be replaced again during complete to the n root compound wire coilings k2 cakes of width, transposition back panel to n roots compound wire from inside to outside
It is followed successively by n-1, n, a.....n-3, n-2；Remaining transposition is once analogized, until coil winding is completed.
In order to be further appreciated that to the present invention, now it is further described below：
1) calculating of the width to more compound wire transposition numbers, the circulation voltage U of wire in each transposition interval is ensured1、
U2、...、UnNo more than allowable value Um。
The average leakage magnetic flux of winding wire is calculated according to coil parameterFurther according to average leakage magnetic fluxCalculate electric leakage
Gesture e, calculated further according to drain potential e and ensureing circulation voltage U1、U2、...、UnNo more than allowable value UmWhen the maximum that allows change
Position cake number k, transposition number N is calculated further according to total cake number m of width to the more compound wires of coil, final transposition number N takes
Integer multiple more than n, calculation formula are as follows：
Wherein, f is frequency, and I is electric current, and W is coil turn, and H is coil reactance height, and S is the leakage field face per cake wire
Product, UmFor the allowable value of circulation voltage.
