Definitions

  • the invention relates to a metallic wire according to the preamble of claim 1 and a winding for transformers according to the preamble of claim 3.
  • paper-insulated wires or The twisted pair used a constant thickness-to-thickness ratio over its entire length Have width.
  • the wires are on a magnetizable metal core wound.
  • the present invention is therefore based on the object of a metal wire for to develop the winding of transformers, which has the disadvantages described above does not have or to provide a winding through which the stray field losses in a transformer can be reduced and the efficiency of the Transformer is improved.
  • FIGS. 1 and 2 Exemplary embodiments explained in more detail.
  • a winding z. B. for a transformer which consists of a Iron core 1 and a cylinder 2 arranged above the iron core z. B. made of cardboard or insulating cardboard.
  • Iron core 1 and cylinder 2 are one in the interior Wire wrapping 3 located.
  • the wire wrap 3 consists of a length of one Copper profile with a rectangular cross-section.
  • the copper profile is now according to the teaching of the invention so that the long axis in the central region 3a of the winding 3 of the copper profile runs parallel to the central axis A of the winding, whereas in the End regions 3b of the winding 3, the long axis of the copper profile perpendicular to Central axis A of winding 3 runs. Between areas 3a and 3b d. H. at 3c the copper profile 3 has an almost square cross section.
  • the copper profile can be a solid flat copper wire, but there is also Possibility to create a profile consisting of a large number of one above the other Partial conductors z. B. to use a so-called twisted pair, which by lashing flat partial conductors can be produced.
  • FIG. 2 In the upper half of FIG. 2 there is a side view of a metallic wire 4 shown according to the teaching of the invention. This consists of a total of five sections 4a, 4b, 4c, 4d and 4e.
  • the sections 4a and 4e have a flat profile perpendicular to the long axis and the sections 4b and 4d an almost square cross section.
  • the middle section 4c is opposite to that Sections 4a and 4e rotated by 90 °.
  • Such a metallic wire 4 can be, for example, by metallurgical connection z.
  • Another method for producing the metal wire 4 is carried out by deforming the individual sections 4b, 4c and 4d by Turkish heads or form rolls.
  • the form rolling mills used are in the lower half of FIG. 2 shown.
  • the form rolling mills 5 and 6 each have two pairs of rollers 5a and 5b or 6a and 6b.
  • the roller pairs 5a and 5b and 6a and 6b can advantageously be driven. They are also adjustable in the direction of the roll gap.
  • Section 4e passes through the form rolling mills 5 and 6 unhindered. If the Section 4d in the first form rolling mill 5, the roller pairs 5a and 5b so that there is an approximately square cross-section. The one in Cross-section square section 4d passes freely through the molding tool 6.
  • Section 4e like section 4d, initially becomes a square cross section shaped.
  • the roller pairs 6a and 6b as shown below, turned on and from the square profile, a rectangular flat profile is formed.
  • the section 4b is formed into a square by the rolling mill 5 and passed through the rolling mill 6 unhindered.
  • Section 4a is not deformed like section 4e and passes freely through the form rolling mills 5 and 6, in which the roller pairs 5a and 5b and 6a and 6b have moved apart.
  • a metallic wire can be made in great lengths, being used for manufacturing wire sections required by windings are separated from the wire length can.
