Definitions

  • the invention relates to an electrical conductor with Roebel characteristics, which is stranded from in particular six individual elements without a central core.
  • the invention has for its object to eliminate the aforementioned disadvantages of the prior art and to provide a conductor in which, using inexpensively available elements, the current displacement (skin effect) and other magnetic losses are considerably reduced, even at high frequencies are.
  • the main area of application for the conductors according to the invention is coils for transformers, chokes and high-energy magnets.
  • the ropes are each composed of 50 to 150 individual enamelled round wires. Higher or lower values could also be used, but if a number below 50 is used, the individual wire becomes too thick for certain cross-sectional requirements and the rope element and the finished conductor made from it are too inflexible. On the other hand, a number of over 150 wires will in most cases be too complex to manufacture.
  • the type of stranding of the individual elements is not important with regard to the Röbel effect, the stranding can therefore also be done with a core and be multi-layered.
  • a plurality of conductors are arranged around a central, preferably metallic, cooling duct, meet the requirements of the single-conductor transposition according to Roebel, consist of elements from a large number of enamelled wires and are reshaped.
  • the individual Enameled wires are additionally coated with an initially elastic mass, which hardens when heated, so that the conductors together with the cooling channel form a firmly connected unit which retains the shape once assumed.
  • Thermoplastics as well as thermosets can be considered as the first elastic mass that hardens when heated. In the former case, polyamides are preferred, in the latter epoxy materials, compatibility with the insulating varnish underneath being required.
  • the individual images show cross sections through the finished conductor within one lay length (360 ° basket rotation).
  • Figure 1a corresponds to the starting point with 0 ° basket rotation
  • Figure 1b a rotation by 60 °
  • Figure 1c corresponding to 120 °
  • Figure 1d corresponding to 180 °
  • Figure 1f finally corresponding to 300 °
  • the transposition is clearly evident from the numbers 1 to 6 of the individual elements.
  • the individual elements 1 to 6 can be solid individual wires or, in turn, elements that are stranded in one or more layers (possibly without Roebel characteristics).
  • the individual wires can be customary enamelled wires with conductors made of copper or non-ferrous metals or non-ferrous alloys and an insulating layer preferably made of suitable thermosets, in particular polyvinyl acetal or polyesterimides for even higher thermal loads.
  • FIGS. 2 and 3 also show a type of deformation of the conductor according to FIG. 1, namely a cross section through a rectangular shaped finished conductor.
  • Figure 2a shows the starting point
  • Figure 2b shows the cross section after half a lay length corresponding to 180 ° or corresponding to Figure 1d.
  • Figure 2 is idealized
  • Figure 3 is shown in practice.
  • FIG. 3 shows a cross section through a typical finished conductor.
  • the elements are not wires, but ropes, denoted by 7, each rope again being made from nine enamelled wires 8. It goes without saying that the ropes 7 are, however, generally made from many more individual wires 8, a multi-layer stranding with core (without locking) being the normal case.
  • a single enamelled wire (8) is shown in FIG.
  • the wire core itself is designated 11, the lacquer layer 12.
  • This is applied in a known manner from thermoset solutions or dispersions, but in individual cases a thermoplastic extruded layer can also be applied as insulation instead.
  • a layer 13 can now additionally be applied, in particular extruded, onto the layer 12, which layer consists of an initially elastic mass which hardens after heating. Such an additional coating is advantageous if the conductor is to be held firmly together in this way or if it is to be kept in a desired shape after being deformed on site.
  • FIG. 5 finally shows a conductor with a cooling channel 20, which can be, for example, a bare square copper tube.
  • a cooling channel 20 can be, for example, a bare square copper tube.
  • Four rectangular conductors 15 are arranged around the latter, the structure of which can be seen in FIG.
  • Each conductor consists of six elements 7, as indicated in the figure.
  • the dimensions of the four conductors 15 are chosen so that the overall structure is again one has a square cross section.
  • the four conductors 15 are wrapped with a glass braid tape 16. It goes without saying that each of the conductors 15 has been blown apart, the elements 7 need not meet the Roebel transposition requirement.
  • the (individual) conductors are formed in a round form, preferably from six elements, during the round stranding and can then be e.g. are deformed into a rectangular, square, trapezoidal shape, depending on the geometric requirements for the construction of conductors with a cooling channel.
