Definitions

  • the invention relates to a multiple parallel conductor, especially a twisted pair, for electrical windings Devices and machines with a plurality of each individually electrically insulated partial conductors that are used together with a Wrapping are provided.
  • the partial conductors are Tool cranked at predetermined points and the location of the Partial conductor in the multiple parallel conductor by cranking changed accordingly, the manufacture of the twisted pair in Contrary to the manufacture of the Röbelriche continuous he follows.
  • the bending or cranking of the partial conductors takes place, for example, on the flat side about the longitudinal axis of the Multiple parallel conductors around, the sequence of the partial conductors in the cross section of the multiple parallel conductor also over several repetitive cycles is maintained.
  • the common winding serves the subconductor, the multiple parallel conductor during winding on a storage drum, during transport and when unwinding hold together by the storage drum and from damage to protect.
  • the winding of the partial conductor is used moreover, the electrical insulation accordingly to reinforce the required dielectric strength.
  • the winding of the partial conductor is used moreover, the electrical insulation accordingly to reinforce the required dielectric strength.
  • the electrical insulation is not required.
  • a multiple parallel conductor is described in WO 95/30991, in which the partial conductor with a woven ribbon with a Mesh width of at least 2 mm are wound, the weft and / or polyester warp threads or one of a Polyester existing blended yarn are made.
  • the woven ribbon can also be partially networked Pre-impregnated epoxy resin.
  • the invention is Problem underlying a multiple parallel conductor for windings electrical devices and machines that and drums and effectively during its transport Damage is protected and also in operation in the wound state optimal cooling of the winding of the electrical device or electrical machine guaranteed.
  • the advantages that can be achieved by the invention exist especially in that the common winding of the Sub-conductor of the multiple parallel conductor immediately before the Production of the winding of the electrical device or electrical machine in a simple and inexpensive way and Way by using the tear string to tear open the Wrapping can be removed.
  • the opening and Unwrapping of the multiple parallel conductor on or from Supply coils and during its transportation become the sub-conductors held together securely and firmly by the well-known wrapping and damage to the partial conductors and their Insulated lacquer layers avoided.
  • the turns of the multiple parallel conductor can on the supply spool with small distance and compact side by side, so that a Damage to the multiple parallel conductor due to slipping and jamming on the supply spool avoided and a large one Length can be rolled up. Since the multiple parallel conductor after the manufacture of the winding no additional elements such as Paper tapes, woven tapes and the like are in the Winding the electrical device or electrical Partial discharges occurring between neighboring machines Windings and coolant jams through the cooling channel cross section obstructing additional elements avoided. Of the multiple parallel conductor according to the invention is also easy and inexpensive to manufacture, because only the additional Arrangement of at least one tear thread below the wrap is required.
  • the tear thread made of a high tensile plastic like a polyamide or polyaramide is formed. This leaves the total cross section of the multiple parallel conductor almost unchanged.
  • the wrap is formed from at least one paper tape.
  • FIG. 1 The examples shown in Figs. 1 and 2
  • Multiple parallel conductor 1 which as a conductor especially for are designed for use in transformer windings, have a plurality of flat, approximately rectangular ones Cross-section having partial conductors 3, the z. B. in two adjacent stacks 4 are arranged, wherein a longitudinally running paper tape 5 between the two stacks 4 can be provided, as shown in FIG. 1.
  • everyone the partial conductor 3 is with its own insulating varnish layer provided adequate electrical insulation ensures between the adjacent sub-conductors 3.
  • To the mechanical strength of the electrical insulation can improve the insulating varnish layer of each partial conductor 3 additionally z. B. coated with a partially crosslinked epoxy paint be.
  • the electrical Isolation of the partial conductor 3 also by wrapping a suitable film, paper or similar materials be trained.
  • the partial conductors 3 are predetermined Clearances cranked by turning flat so that their location in the total cross section of the multiple parallel conductor 1 in comparatively short intervals changes regularly.
  • the Cranking points are denoted by 7 in FIG. 1.
  • a common winding 9 for example applied from paper tapes.
  • the winding 9 usually consists of one to five layers of paper tape and completely covers the partial conductor 3. A minor one The number of layers simplifies the removal of the Wrapping 9.
  • the wrapping can have 9 gaps. It is also conceivable to use a instead of the winding 9 closed, e.g. B. provide extruded plastic cover.
  • the tear thread 11 is e.g. B. made of a high tensile plastic such as a polyamide or polyaramide. But he can e.g. B. also from one with glass fibers or other high tensile strength reinforced plastic, made of hemp or made of another high tensile strength material. In the It should be noted, however, that the tear thread 11 has the smallest possible cross section and that from Tear thread no danger to the insulating varnish layer Partial conductor 3 goes out.
  • Fig. 1 is on the outside of the wrap 9 z.
  • B. a in the longitudinal direction of the Multiple parallel conductor 1 trending, at its the Wrapping 9 facing side with an adhesive provided and glued to the winding 9 tether 13 arranged.
  • the tether 13 serves the individual Components of the winding 9 after tearing stick together and so the complete removal of the To simplify winding 9 and the contamination by loose Avoid components of the wrap.
  • FIG. 2 differs from that shown in FIG. 1 Embodiment essentially in that the in Longitudinal direction of the multiple parallel conductor 1 extending Retaining strap 13 on the side opposite the tear thread 11 of the multiple parallel conductor 1 between one of the partial conductor stacks 4 and the inside of the winding 9 is arranged.
  • the tether 13 is on in this second embodiment its side facing the winding 9 with a Provide adhesive. By means of this adhesive it is Tether 13 glued to the inside of the wrap 9.
