Definitions

  • the invention relates to a multiple parallel conductor, i.e. a multiple conductor with parallel individual conductors, for electrical windings Machines and devices, in particular twin ladders and triple ladders, consisting of at least two individual conductors with an essentially rectangular conductor cross section, wherein each individual conductor is enamel-insulated, at least one of the longitudinal contact surfaces the flat sides of the individual conductors with a crosslinkable adhesive (2) is coated, and the conductor bundle preferably with paper insulation (3) or is surrounded by a tether.
  • a multiple parallel conductor i.e. a multiple conductor with parallel individual conductors, for electrical windings Machines and devices, in particular twin ladders and triple ladders, consisting of at least two individual conductors with an essentially rectangular conductor cross section, wherein each individual conductor is enamel-insulated, at least one of the longitudinal contact surfaces the flat sides of the individual conductors with a crosslinkable adhesive (2) is coated, and the conductor bundle preferably with paper insulation (3) or is surrounded by a t
  • a multiple parallel conductor of the type mentioned above is, for example, in EP 030 338 described.
  • paint-insulated conductors are considered described disadvantageously and a variant is proposed at which the non-insulated individual conductors by a spacer at a distance are kept apart.
  • One disadvantage of this solution is that the multiple parallel conductor is mechanically stable due to the spacer element, however occupies an undesirably higher volume. Furthermore, this results in Solution Problems related to the dielectric strength of non-oil impregnable Gas bubbles, especially around the edges.
  • the individual conductors were coated with an epoxy resin after the paint insulation provided, the single conductor completely with a resin in the B state was surrounded. These individual conductors were then twisted, stranded or simply arranged in parallel, wrapped with paper insulation or tether and hardened.
  • the conductors processed for example, into a transformer winding then pre-pressed, hardened and optionally re-pressed.
  • the resin in the B state has escaped from the edges of the conductors, whereby gas inclusions could form.
  • gas inclusions could form.
  • solvent or air bubbles were trapped, it could Operation to mica and subsequently to the destruction of the insulation system come because these gas inclusions or such cavities after Heat treatment process were no longer oil-impregnable.
  • the object of the invention is to provide a multiple parallel conductor whose Properties during and after winding, as well as after curing the required Meets criteria, both mechanical and electrical, and certainly not Oil-impregnable gas inclusions, especially in the narrow sides and around the edges excludes.
  • the invention is based on a multiple parallel conductor of the aforementioned Kind characterized in that the edge areas and narrow sides of the individual conductors are free of adhesive.
  • the adhesive is a partially cross-linked Reaction resin, preferably an epoxy resin.
  • the epoxy resins have both Desired adhesive strength, as well as the required mechanical strength in the Short shot case on.
  • the adhesive is an anaerobic cross-linking Synthetic resin.
  • these air-hardening systems do not offer any Impairment of the desired dielectric strength, on the other hand, the Adhesive strength increased for this application, but they do not require any additional Hardening and can therefore be processed faster and cheaper.
  • the adhesive is at most 95%, especially applied to 80% of the longitudinal surface. This leaves the edge and Narrow side area free of glue because the glue also on the others Manufacturing steps can no longer emerge.
  • FIG. 1 shows one Twin conductor with one-sided adhesive layer
  • Fig. 2 shows a twin conductor with double-sided 3 and a stranded conductor.
  • the enamelled wire conductors 1 with adhesive resin 2 are on the longitudinal contact surfaces coated and wrapped with paper insulation 3.
  • the bundle of ladder will be later hardened.
  • the adhesive surface should be approx. 80% of the contact area and the edge and the narrow side area must remain free of adhesive.
  • the enamelled wire 1 with adhesive resin 2 are both on the Longitudinal contact surfaces and coated on the outer longitudinal surfaces.
  • the paper insulation 3 is wound together and thus results in a slight stronger, but more compact, twin ladder. This also applies analogously to Multiple parallel conductor consisting of three, four or more conductors.
  • This wire conductor 3 is a single conductor 1 consisting of a twisted conductor with the partial one Provide coating 2.
  • This wire conductor can either be with paper insulation or be provided with a tether.
  • This tether may be a large-mesh network.
  • the wire conductor does not necessarily have to be insulated be surrounded. The bundle of conductors remains in place due to the fastening of the individual conductors 1 practically yourself.
  • the conductor bundle has one very high mechanical strength and the electrical criteria are guaranteed.
