Definitions

  • the invention relates to a superconducting winding with at least one at least substantially band-shaped HTS conductor, which is set in individual turns of the winding under a predetermined winding tension and on its outside a reinforcing strip of a material having a relatively higher tensile strength than that of the HTS conductor assigned.
  • the invention further relates to a method for producing such a superconducting winding.
  • a corresponding winding and a method for their preparation are the JP 10-92630 A , which is considered as the closest prior art.
  • LTS material low-T c superconducting material
  • HTS material high-T c superconductor material
  • the conductors are of the so-called monocore or multifilament type, with one or more superconducting conductor cores of the HTS material being embedded in an Ag matrix.
  • To build the winding is a precursor of the HTS conductor, in which the Superconducting phase and the corresponding structure are not yet fully formed, wound together with a reinforcing strip of an Ag alloy around a winding core.
  • the material of the reinforcing strip has a greater tensile strength than that of the HTS conductor.
  • the construction After the construction has been completed, it is subjected to an annealing treatment, whereby the superconducting phase and the structure are formed, and a metallurgical bond is created between the matrix material of the HTS conductor and the reinforcing strip at the common contact surface. Because of the required annealing, the construction of the winding is correspondingly expensive.
  • Corresponding conductors can consist of largely band-shaped, mutually transposed individual conductors, each of which is either of the so-called monocore or multifilament type. They are z. B. from the WO 01/59909 A1 known. Also with band-shaped individual conductors of the coated conductor type according to the WO 03/100875 A are suitable for a construction of HTS cable ladders.
  • Object of the present invention is therefore to provide a structure of a superconducting winding with the features mentioned, which allows a machine manufacturing, without the mentioned problems are given. Furthermore, a suitable method for the construction of such a winding is to be created.
  • the winding should be designed with the features mentioned above to the effect that the HTS conductor of Röbelleiter type is transposed with each other, at least largely band-shaped HTS single conductors and is intended to metallurgically, the reinforcing strip connected to the prefabricated end product of the HTS conductor should not be wound in the individual conductor windings under a higher winding tension than that of the HTS conductor.
  • FIG. 1 a structure for the production of the winding from the outset, as well their FIG. 2 a section of this winding
  • FIG. 1 shown side view of a partially created superconducting winding 2 is assumed by known devices for the preparation of such windings.
  • the winding is created around a central winding body 3, which has a circular cross-section according to the selected embodiment.
  • a central winding body 3 which has a circular cross-section according to the selected embodiment.
  • other geometries of the bobbin for example, with sections straight outer contour as in the case of so-called race track (Race Track) coils may be provided.
  • To the winding body 3 is continuously and simultaneously with a at least substantially band-shaped HTS-Röbelleiter 4 a Arm istsband 5 wound, wherein the reinforcing tape should come to rest on the outside of the HTS Röbelleiters. HTS-Röbelleiter and Arm michmaschinesband be unwound from supply spools, not shown in the figure.
  • the reinforcing tape 5 is wound around the winding body 3 tangentially by at least 1.5 times, preferably at least 3 times, a larger winding tension than that of the HTS cable conductor.
  • the winding tension WZ1 should be below the critical tension of the HTS-Röbelleiters, which is generally below 200 MPa, preferably below 150 MPa. So z. B. known HTS Röcelleiter with Bi-2223 cuprate material critical tensile stresses between 110 and 150 MPa.
  • Suitable tensile stresses WZ1 are between 10 MPa and 100 MPa, in particular between 20 and 50 MPa.
  • the tensile stress WZ2 for the reinforcing tape 5 is then for example 150 MPa.
  • the reinforcing strip 5 whose width should advantageously correspond to that of the HTS Röbelleiters 4, comes as a material virtually any question that allows a sufficiently high winding tension in the order of magnitude. Examples are stainless steel bands or bands of a Cu alloy. Also suitably resistant plastic materials are suitable, which are optionally fiber-reinforced.
  • the reinforcing tape can also be formed as a fabric, wherein the fabric parts are metallic or made of plastic.
  • FIG. 2 shows a cross section through the partially created winding after FIG. 1 ,
  • the winding has three windings w1 to w3, which are formed by jointly winding the winding core with the HTS conductor 4 and the reinforcing tape 5.
  • the Röbelleiter has an approximately rectangular cross-section, which is occupied by, for example, 9 about band-shaped HTS single conductors 6i.
  • the structure of the cable ladder from such individual conductors is general known (see the cited WO 01/59909 A1 and WO 03/100875 A2 ).
  • These individual conductors 6i generally each have an insulating covering.
  • an insulating tape may be wrapped if the reinforcing tape itself is not insulating.
