Problems solved by technology

However, up to now in a continuous manufacturing process for the production of continuous transposed conductors it has not been possible to twist together two or more single conductors placed side by side in one working step
This method of producing transposed conductors has therefore hitherto been uncontrollable for production-technical reasons

Embodiment Construction

[0030] FIG. 1 shows a long-known transposed conductor 1 , which consists of a number of electrically insulated individual conductors 2 which are arranged in two individual conductor stacks 3 . In this case, the individual conductors 2 are known to be twisted in such a way that the individual conductors are transposed from the uppermost layer to the lowermost layer. In this case, the individual conductors 2 have a rectangular cross section and rounded edges. In order to ensure that the single wire bundles are assembled together to form the transposed wire 1, or to protect the transposed wire, a winding layer 4 may also be provided with mesh tape, paper tape or similar materials.

[0031] figure 2 A transposed conductor 10 according to the invention is shown, which consists of a plurality of individual electrically insulated individual conductors 11 . In transposed conductors 10 , every two adjacent individual conductors 11 are combined to form an individual conductor group 12...

Abstract

In order to realize the manufacture of transposed conductors with co-twisted, side-by-side sub-conductors from the production technology, it is suggested that at least one of the single conductors (11) of the single-conductor group (12) be defined between two single conductors placed side by side ( 11) The rounding radius (r2) of the edge (15) of the contact surface (14) between them is designed to be smaller than the rounding radius (r1) of the outer edge (13) of the single wire group (12).

Description

technical field [0001] The invention relates to a continuous transposed conductor consisting of a plurality of individual, electrically insulated single conductors, in which every two or more superimposed single conductors are combined to form a single conductor group and are twisted together, wherein the edges of each individual conductor are rounded; the invention also relates to a transformer having a winding made of such continuous transposed conductors. Background technique [0002] Among the continuous transposed wires are considered wires which are produced in great lengths - for example lengths of several kilometers are not uncommon - and which are subsequently processed into windings for electrical equipment, for example transformer windings. During the winding process, the transposed wire is subjected to severe bending. In contrast, winding bars or Roebel bars of small length are manufactured by hand and assembled into the windings of electrical equipment such as ...
