Definitions

  • the invention relates to a multiple wire conductor according to the preamble of claim 1. and a method for producing a multiple twisted conductor according to claim 4.
  • power transformers are used to limit the current density several twisted pairs axially wound in parallel.
  • Multiple stranded conductors consisting of two or three individual twisted pairs with a common insulation for use. These multiple conductors have multiple conductors, each of two juxtaposed stacks of enamelled insulated sub-conductors and one Have common insulation, which usually consists of a paper winding.
  • the present invention has for its object to provide a multiple wire to provide a reduced external dimension and to specify a method with which the multiple wire conductors are inexpensive to manufacture.
  • the Multiple wires with a better fill factor, the losses of the transformer reduce.
  • the main advantage of the invention is the fact that compared to Multiple conductor, as it has been used so far, on a separate insulation of the individual wire ladder is dispensed with. If necessary, is between each A spacer is provided for the wire conductors, which damages the mechanical damage excludes paint-insulated conductor during transport and processing.
  • the thickness of the Spacers should be less than twice the wall thickness of the previous one used paper wrapping of the wire ladder.
  • Figures 1a and 1b show a section through multiple stranded conductors according to the prior art Technology
  • Figures 2a, 2b and 2c multiple wire according to the teaching of the invention
  • Figure 3 is a schematic representation of the manufacturing process.
  • the multiple conductor according to Figures 1a and 1b consist of two side by side arranged twisted conductors 1 and 2, each of which is twisted from two stacks or entrained lacquer-insulated partial conductor 3 exists.
  • Each wire conductor 1, 2 is of a separate one Insulating layer 4, preferably surrounded by paper wrapping.
  • Both wires 1, 2 are of a common insulating layer 5, preferably a paper wrapping surround.
  • the wire conductors 1, 2 are separated by a Spacers 6 isolated from each other.
  • FIGS. 2b and 2c are the two wire conductors 1 and 2 bare, i.e. it is only the partial conductor 3 with a thin one Provide paint insulation.
  • a spacer 6 e.g. provided from pressboard.
  • a wrapping 5 preferably a paper winding surrounds the twisted pair 1 and 2. The wall thickness of the Wrapping is based on the requirements of the transformer manufacturer.
  • the wall thickness is equal to the sum of the wall thicknesses of the insulating layer 4 and Insulating layer 5 of the multiple conductor according to FIG. 1.
  • the exemplary embodiment according to 2b are separate spacers 6 between the partial conductor stacks intended.
  • FIG. 3 A diagram of the manufacturing process is shown in Figure 3.
  • the one with this twisted pair 1 wound coil 9 is integrated into the production line of a second twisted conductor 2.
  • this production line becomes a stranded conductor by pulling off
  • the two wire conductors 1 and 2 are in front a winding head 10, with one of a coil 11 deducted spacer 6 is supplied from pressboard.
  • In the winding head 10 is a wrap 5 from several layers of paper tape as a common wrapping on the two wire conductors 1 and 2 wound.
  • the finished Mehrfachdrilleiter 12 is on a Transport coil 13 wound and can be delivered to the transformer manufacturer become.
