Definitions

  • the invention relates to an electrically conductive wire according to the preamble of patent claim 1 and to a method for producing the wire.
  • a designated as winding wire wire goes out of the DE 197 03 161 A1 out. It is surrounded over its entire surface by an insulating varnish, which is preferably applied in several thin individual layers.
  • the insulating varnish must be baked, at the same time solvent must be removed environmentally friendly.
  • a baked enamel is applied intermittently, and in particular as in several layers. The baked enamel is surrounded by an insulation liner.
  • a wire as described above is used, for example, as a flat wire of rectangular cross section for producing windings for transformers and electrical machines.
  • the wire is surrounded according to the known for many years prior art of a layer of paper as insulation, which also serves as a spacer to adjacent, arranged in a winding turns of the wire.
  • the production of such a wire and a winding made therefrom is much easier than the wire described above.
  • practice has shown that such a wire is not resistant to corrosion in the long term. Rather, during the operation of an electrical device equipped with such a wire, conductive copper sulfide is formed by corrosive constituents of the oil used as the coolant, thereby damaging the layer of paper. An appropriately constructed winding is then quickly unusable, so that the associated device stops working.
  • the entrance-mentioned FR 2 805 657 describes an electrical conductor for transformers, which is surrounded by two layers of paper, which are glued to the conductor and each other and also have adhesive material on the outer surface.
  • the two layers of paper consist of adhesive tapes wrapped around the conductor.
  • the first layer which directly surrounds the conductor is an adhesive layer which bonds the overlying paper layer to the conductor.
  • the invention has for its object to make the wire described above so that it has a further simple production improved corrosion resistance.
  • the polymeric material can be applied directly to the wire and then crosslinked using conventional methods and apparatuses in the painting industry, including on conductors of larger dimensions.
  • the layer of paper can then be formed around the wire in conventional technology.
  • Such a polymeric material contains only relatively little solvent, so that no expensive post-treatment is required. This is true with respect to the material, even when it is applied to a band of paper, which is then wrapped around the wire so that the polymeric material adjacent to the wire surrounds the same gapless.
  • the polymeric material is resistant to commercial oils over time, so that with the same constructed windings for oil cooled devices have a significantly increased life.
  • the thus coated wire 1 is then guided into a cross-linking device 4, in which the polymeric material is crosslinked by supplying heat. Depending on the dimensions or the cross section of the wire 1, the crosslinking takes place, for example, at a temperature between 300 ° C and 350 ° C temperature. The layer 3 then adheres firmly to the wire 1. Finally, in a device 5, a layer 6 of paper around the wire 1 is formed around. For this purpose, for example, a band of commercially available insulating paper can be wound around the wire 1.
  • an epoxy resin is particularly suitable. It is also possible to use alkyl resins or polyesterimides, also in modified form.
  • a tape 7 can be used, which consists of a preferably unilaterally provided on its entire surface with a layer 8 of a polymeric material paper tape 9.
  • a polymeric material paper tape 9 may again consist of commercially available insulating paper.
  • the tape 7 is wound around the wire 1, that results in a corresponding layer 3, the wire 1 surrounding gap 8 of polymeric material.
  • the band 7 can be wound around the wire 1 in shock. However, in a preferred embodiment, it is wrapped around the wire 1 with overlap. Is in Fig. 5 indicated by dashed lines.
  • the polymeric material can also be finally crosslinked in this variant of the production of the wire. But this step can also be dispensed with, because windings are dried from such a wire after its completion by heating at temperatures that are sufficient for the crosslinking of the polymeric material.
