Definitions

  • the invention relates to a liquid-cooled tape winding and can be found in chokes or transformers - especially dry-type transformers, such as cast-resin transformers - application.
  • a directly cooled strip-layer winding for transformers which has one or more coil-coaxial cooling layers which have substantially the same axial length as the winding and are arranged at appropriate radial distances from the desired cooling.
  • Each cooling layer consists of a bundle of a plurality of parallel, tubular cooling conductors of electrically conductive material, which are spirally wound into a layer, wherein the inlet and outlet of the bearings is arranged at the ends of the windings.
  • the cooling tube bundle is connected in series with the strip conductor, so that the cooling tube layer is electrically equivalent to a strip layer.
  • the invention is based on the object of specifying a liquid-cooled ribbon winding optimized with regard to cooling.
  • the advantages that can be achieved with the invention are, in particular, that the heat-producing surface of the strip winding completely comes into contact with the cooling layer (cooling layer), which contributes to a uniform dissipation of the heat energy generated within the winding. Local over-temperatures are avoided. Due to the improved heat dissipation, the winding can be made very compact, resulting in a volume and weight-optimized tape winding. Since the cooling layer is electrically insulated from the winding strip, no special measures with regard to electrical insulation are required with regard to a return cooler for the cooling liquid, including the required cooling lines.
  • a cooling layer 8 is provided, which is formed by means of a cooling channel.
  • the cooling channel has two arranged on the head sides of the tape winding 1 / accessible cooling channel connections 9, 10, which are connected via cooling lines 16, 17 with a recooler 18.
  • the preferably suitable for liquid cooling cooling channel can, for. B. in the form of a spirally wound cooling tube arrangement, so that a cooling layer of densely adjacent to each other over the entire width of the winding arranged cooling tubes results.
  • the first winding end terminal 2 is formed by the beginning of the winding band of the winding part 5, z. B. by a welded thereto / soldered rail.
  • a terminal rail 6 (lead-out rail) is welded / soldered to the end of the winding band of the first winding part 5.
  • an initial rail 13 is welded / soldered to the beginning of the winding tape of the winding part 12.
  • the end rail 6 and the top rail 13 are the end outside the tape winding 1, preferably on the first head side of the tape winding 1 by means of an electrical connection 14 permanently electrically connected to each other, for. B. welded / soldered.
  • the second winding end terminal 3 is formed by the end of the winding band of the winding part 12, respectively by a rail welded / soldered thereto.
  • the recooler 18 via cooling lines 16, 17 with the cooling channel connections 9, 10 as well as arranged parallel thereto cooling lines 28, 29 with the cooling channel connections 26, 27, which results in a parallel cooling circuit of the cooling channels 8, 25,
