Definitions

  • the present invention relates to a mounting device according to the preamble of claim 1 and to a use of this mounting device.
  • the invention relates to a prior art of mounting devices for a meandering winding, as described in GB-A-1 164 442.
  • meandering preformed windings made of resistance wire are stored in elongated recesses at the end, electrically insulating spacers. Spacers between the winding ends are not provided.
  • EP-AI 0 066 902 (EPC Art. 54 (3)), which is considered to be prior art, to fasten a liquid-cooled, meandering power resistor in the area of its rectilinear conductor sections in panels.
  • the panels have round holes for the conductor sections so that the U-shaped bends in the power resistor cannot be pushed through.
  • the invention solves the problem of eliminating the disadvantages of the known and creating a holder for a meandering winding, which ensures simple spacing of the partial conductor of the winding sufficiently and the mounting of the mounting device with the Winding facilitated.
  • An advantage of the invention is that the meandering winding can be preformed and the spacers can be inserted from both sides in the longitudinal direction of the winding.
  • the development according to claim 2 stabilizes the position of the end parts of the winding.
  • the advantage of claim 3 lies in the space-saving construction.
  • the variant according to claim 4 is also space-saving and is suitable for long windings. It enables the winding to be arranged in a cylindrical housing.
  • the advantage of the embodiment according to claim 5 is that the winding only touches the spacers in small areas, whereby the spacers can be sufficiently thick for mechanical reasons.
  • the development according to claim 6 enables all spacers to be fastened on a rod-shaped carrier, so that the spacers form a dimensionally stable whole with the winding even without a housing.
  • Claim 7 shows an advantageous use of the mounting device according to the invention, in which case the resistor is cooled in a cooling liquid, preferably in deionized water.
  • a meandering winding 1 made of round wire is shown.
  • the winding 1 is provided with preformed curved parts 1 ', so that it forms anti-parallel sections and has only a low inductance as a whole when the current flows through.
  • a spacer 2 was inserted from above, another spacer 3 from below.
  • the spacer is provided with a hole 4 and with several elongated holes 5. Only the elongated holes 5 are made in the spacer 3.
  • the mutual displacement of the elongated holes 5 is visible. This displacement enables each of the parallel sections of the winding 1 to be supported with the spacer 2 from one side and with the other spacer 3 from the other side.
  • the winding 1 In the central region A of the winding 1 between the spacers 2 and 3, the winding 1 is thus carried, in the end region B the winding 1 is without support.
  • the length of the areas A and B depends on the mechanical strength of the specific winding 1, the material, the wire cross section and the winding spacing to be observed in particular.
  • the right part of FIG. 1 shows the variant in which the right end of the winding 1 is also guided through the upper spacer 2.
  • the hole for this end is labeled 4 '.
  • the spacers can be perforated in different ways, e.g. is shown in Fig. 1, they can also be carried out the same way, where they are used mutually in reverse.
  • FIG. 2 shows a view of the upper spacer 2 and in FIG. 3 the lower spacer 3.
  • the middle parts in Figs. 1 to 3 have been omitted.
  • FIG. 4 shows a variant which essentially corresponds to that according to FIG. 1, but in which, for mechanical reasons, two upper spacers 2 and two lower spacers 3 are arranged.
  • spacers 6 and 7 are illustrated, which are intended for a three-day winding 1.
  • FIG. 7 shows a spacer 8 for a spiral mounting of the meandering winding 1. This winding 1 is not shown in FIG. 7.
  • the spacer 8 is disc-shaped in this exemplary embodiment and is provided with a fastening opening 10. By means of this fastening opening, two or more spacers 8 can be fastened on a rod-shaped carrier.
  • the elongated holes 5 each have a taper 9 in the central zones, so that the outer cross sections of the holes 5 are larger than the inner cross section. This construction facilitates assembly, the contact area of the winding 1 with the spacer 8 remaining small.
  • FIG. 9 The section IX-IX from FIG. 7 is illustrated in FIG. 9. This section runs perpendicular to the section VIII-VIII shown in FIG. 8. Parts of the winding 1 are shown in the left part, the taper 9 of the elongated holes 5 is clearly shown in the right part.
