Abstract
The utility model relates to the field of transposed conductors, in particular to a multi-section series transposed conductor. The multi-section series transposed conductor comprises enameled copper flat wires. Each enameled copper flat wire comprises a bare copper flat wire and a paint film arranged outside the bare copper flat wire. The multi-section series transposed conductor is characterized in that the number of the enameled copper flat wires is an odd number; all the enameled copper flat wires are arranged in two rows; the wide faces of each row of enameled copper flat wires are contacted with each other; the same turning transposition is performed on the top faces and the bottom faces of the two rows of enameled copper flat wires along narrow faces; and each enameled copper flat wire comprises at least two sections of copper flat wires which are different in wire gauge and are connected end to end. The multi-section series transposed conductor has the advantages that the length of each weld zone of the transposed conductor is controlled within a range of 1000mm. Points of weld of the single copper flat wire are mutually staggered, therefore, the electrical characteristic requirement of a transformer winding is met, and the points of weld are proper in length, so that the weld strength requirement is ensured.
Description
Technical field
The utility model relates to the transposition line field, a kind of specifically multi-section serial transposed conductor.
Background technology
Transposed conductor is mainly used in makes oil-filled transformer or other electrical equipment winding.At present, the wire gauge of every of transposed conductor enameling copper strap wire is the same.But application along with big capacity, high-voltage power transformer; Also have higher requirement for transposed conductor; Power transformer product is low to loss, the low direction of cost develops; Connect transposed conductor becomes the effective ways of further reduction load loss more, and existing transposed conductor can not satisfy the requirement of consumption reduction because every copper strap wire specification is the same.
The improvement that also has pair transposed conductor to carry out in the existing patent is 201120075738.6 like application number, and the applying date is 2011-3-22; Name is called the utility model patent of " netted rope binding type self-adhesion acetal semihard enamel-cover transposed conductor "; Its technical scheme is: comprise the transposition core, the transposition core comprises many semihard copper strap wires, and semihard copper strap wire outside scribbles the insulation enamelled coating; The insulation enamelled coating is the acetal enamelled coating, and single acetal paint envelope curve outside scribbles self-adhesive layer; Said transposition core outside is surrounded with the polyester guipure, the outer wrapped outer layer insulation paper of polyester guipure, and transposition core bottom can be provided with aromatic series paper or crimped paper as required.
Summary of the invention
Can not be implemented in the effect that a transposed conductor in the winding is connected by two or more copper strap wires successively for what overcome that existing transposed conductor exists; Existing special proposition is a kind of can hold a kind of multi-section serial transposed conductor of a plurality of specification copper strap wires according to actual needs simultaneously.
For realizing the foregoing invention purpose, the concrete scheme of the utility model is following:
A kind of multi-section serial transposed conductor; It comprises enameling copper strap wire, and said enameling copper strap wire comprises bare copper flat wire and be arranged on its outer paint film that it is characterized in that: said enameling copper strap wire quantity is the odd number root; Each enameling copper strap wire is two row and arranges; The wide face of every row enameling copper strap wire contacts, two row enamelled wires top and followingly do the same transposition that turns to along leptoprosopy, and said every enameling copper strap wire comprises that the copper strap wire of the different wire gauges of at least two joints is end to end.
The copper strap wire that saves different wire gauges in the said every enameling copper strap wire welds together from beginning to end.
The weld of the adjacent two joint copper strap wires on the said single enameling copper strap wire is a pad; The mode that staggers each other of the pad of many copper strap wires is arranged; The pad interlaced arrangement of adjacent two copper enameled sheet wires; The distance that staggers is greater than 200mm, and the weld zone length of a sections is no more than 1000mm.
Said two row enameling copper strap wires are surrounded with insulating barrier outward.
Said insulating barrier is an electric insulation paper.
The advantage of the utility model is:
1, the utility model makes within the length control 1000mm of each weld zone of transposed conductor.Wherein, the pad of single copper strap wire staggers each other, satisfies the electrical characteristic requirement of Transformer Winding, makes pad that suitable length is arranged again, guarantees the weld strength requirement.
The Transformer Winding of 2, being made by the utility model transposed conductor can be improved the equipment electric property, makes capacitance profile even, and loop construction is compact, and conserve space helps the miniaturization of product, can increase mechanical strength simultaneously, strengthens the anti-short circuit capability of product.

Fig. 2 is that the pad of a weld zone of transposed conductor distributes.
Label among the figure: 1 bare copper flat wire, 2 paint films, 3 insulating barriers, 4 pads.
Embodiment
The multi-section serial transposed conductor comprises enameling copper strap wire; Said enameling copper strap wire comprises bare copper flat wire and is arranged on its outer paint film; Said enameling copper strap wire quantity is the odd number root, and each enameling copper strap wire is two row arranges, and the wide face of every row enameling copper strap wire contacts; Two row enamelled wires top and followingly do the same transposition that turns to along leptoprosopy, said every enameling copper strap wire comprises that the copper strap wire of the different wire gauges of at least two joints is end to end.The copper strap wire that saves different wire gauges in every enameling copper strap wire welds together from beginning to end.The weld of the adjacent two joint copper strap wires on the single enameling copper strap wire is a pad; The mode that staggers each other of the pad of many copper strap wires is arranged; The pad interlaced arrangement of adjacent two copper enameled sheet wires, the distance that staggers are greater than 200mm, and the weld zone length of a sections is no more than 1000mm.All the other wire transpositions and technologies such as insulation recovery are all carried out on special equipment with original identical.Two row enameling copper strap wires are surrounded with insulating barrier outward.Insulating barrier is an electric insulation paper.
The transposed conductor that the utility model proposes is lined up two row by the enameling copper strap wire of a greater number (odd number) by wide contact, on two row enamelled wires with below do the same transposition that turns to along leptoprosopy, and closely hold composition with electrician's insulating paper.Each root copper strap wire of this transposed conductor is not with a kind of wire gauge from the beginning to the end, and wire gauge more than 2 kinds promptly forms by the copper strap wire of plurality of specifications is end to end, so be called the multi-section serial transposed conductor.
