Abstract
The utility model provides a transposition structure of a 110kV transformer coil. The transposition structure comprises N turns of guide wires arranged from top to bottom in sequence, N is an integral larger than 1, the guide wires are arranged at guide wire transposition positions, the first guide wire is arranged at the position of the guide wires at the tail end, and the other guide wires are arranged at the positions of the N-1 guide wires in sequence. The guide wire transposition positions comprise the position of 1/4 of the N turns of guide wires, the position of 1/2 of the N turns of guide wires and the position of 3/4 of the N turns of guide wires. According to the structure, the manufacturing specification of an insulation part is reduced, and the operation is simple. The coil is wound more compactly, the width size can be reliably guaranteed, and product quality is improved.
Description
Technical field
The utility model belongs to the winding mechanism of transformer coil, relates in particular to a kind of 110kV transformer coil conversion structure.
Background technology
110kV high-power transformer single spiral coil, for low-voltage, large current coil structure, its wire be many lenticular wires or transposed conductor and around.For guaranteeing and isometric around wire, in winding process, parallel conducting wire need to be replaced, the position of the every shared stray field of wire is evenly equated, can reduce circulating current, thereby reduce supplementary load loss.According to the radical of parallel conducting wire, take different interchanging methods, 4 and around, adopt " 2,1,2 " transposition, 4N root and around, N is integer, adopts " 2,4,2 " transposition.Above interchanging method, when standard replaces, curves " S " by one, outside wire curved, and it is curved that then ecto-entad bends every wire " S " successively.The outermost wire of line segment, by transposition, drop to inner side, below this root wire, to pad a thickness by large gradually little wedge piece, therefore the wire of inner side just rises to outermost gradually, below this root wire, will pad a thickness by little gradually large wedge piece, the wedge piece size of thick one end equals line segment width and to size, deducts the thickness of a wire.In each " S " crook, all deduct the thickness of a wire later, be decremented to successively zero.
At present, be to improve transformer anti-short circuit capability, large current coil adopts the tack transposed conductor of high-yield strength, during wire producing " S ", and easily resilience, and easily loose during wedge piece colligation, coil width is difficult for guaranteeing to size.
Utility model content
For above-mentioned defect or deficiency, the purpose of this utility model is to provide a kind of 110kV transformer coil conversion structure.
For reaching above object, the technical solution of the utility model is:
Comprise the N circle wire of arranging successively from top to bottom, N is greater than 1 integer, is positioned at wire transposition place, and the first line conductor row is distributed in tail end lead location, and all the other wires are arranged in the lead location of N-1 successively.
Described wire transposition place comprises 1/4th places, 1/2nd places, 3/4ths places of N circle wire.
Comprise four circle wires, be respectively the first wire, the second wire, privates and privates, the order being positioned at after four wire transpositions of wire transposition place are arranged is the second wire, privates, privates, the first wire.
Compared with the prior art, the beneficial effects of the utility model are:
The 110kV transformer coil conversion structure that the utility model provides, due to by the N circle wire arranging in wire transposition place, the first line conductor row is distributed in tail end lead location, makes the curved wire of the first wire " S " to internal coil diameter side, " S " can cross over 4～5 stay intervals, avoids bad wire insulation of card; All the other wires are arranged in the lead location of N-1 successively, and insulating part manufacturing specification is reduced, simple to operate.Coil winding is consolidation more, and width can obtain Reliable guarantee to size, and product quality improves.
Accompanying drawing explanation
Fig. 1 is the utility model 110kV transformer coil conversion structural representation.
In figure, 1 is the first wire, and 2 is the second wire, and 3 is privates, and 4 is privates.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
The utility model provides a kind of 110kV transformer coil conversion structure, comprise the N circle wire of arranging successively from top to bottom, N is greater than 1 integer, is positioned at wire transposition place, the first line conductor row is distributed in tail end lead location, and all the other wires are arranged in the lead location of N-1 successively.Described wire transposition place comprises 1/4th places, 1/2nd places, 3/4ths places of N circle wire.
Single spiral coil interchanging method is " N-1 " inferior transposition.When coil transposition radical be N root and around time, coil carries out N and subtracts transposition once.
Shown in Figure 1, take four tack transposed conductors and around coil be example, the realization of interchanging method is described.
Four circle wires are respectively the first wire 1, the second wire 2, privates 3 and privates 4, four circle wires form coil, and the order being positioned at after four wire transpositions of wire transposition place are arranged is the second wire 2, privates 3, privates 4, the first wire 1.
At coil, 1/4,1/2,3/4 number of turn place replaces.Each transposition, the curved wire of a bending coil wire of outermost " S " is to internal coil diameter side, " S " can cross over 4～5 stay intervals, avoid bad wire insulation of card, line segment and stay overhead positions correcting wedge stretching, correcting wedge thickness is conductor thickness, and the wedge piece size of wide one end equals line segment width and to size, deducts the thickness of a wire.Three wires of coil remainder, bending " S " is simultaneously curved to coil outer diameter side, line segment and stay overhead positions correcting wedge stretching, correcting wedge thickness is conductor thickness, the wedge piece size of wide one end equals the thickness of a wire of line segment.Insulating part manufacturing specification reduces, simple to operate.Coil winding is consolidation more, and width can obtain Reliable guarantee to size.
