Definitions

  • the invention relates to a saddle-shaped coil winding using superconductors on a tube jacket surface with axially extending, straight winding sections and between them bent on opposite end faces, winding heads forming winding sections.
  • the invention further relates to a method for producing such a coil winding.
  • a corresponding method for producing such a coil winding can be found in JP 06-196314 A.
  • Racetrack coils are flat windings in which the turns always lie within a winding plane. If stacked such racetrack coils, the stack thus has no opening in the longitudinal direction (so-called "aperture") .
  • the raceway coils In rotating machines with a continuous wave, therefore, the raceway coils must be mounted above and below a central area (cf., for example, DE 199 43 783 A1) Therefore, in the axially extending, straight winding sections of the coil winding there is a free space not occupied by the winding, which leads to a corresponding reduction of the usable field strength This results in a more effective use of the superconducting windings, for example in rotating machines, provided that the superconductors are correspondingly deformable without sacrificing their superconducting properties.
  • Conically shaped coil windings with band-shaped HTS conductors have also been proposed (see WO 01/08173 A1). at Although this coil geometry, the winding is curved; However, here are the head of the individual turns on the straight sections and in the winding head each within a common plane. The flat sides of the conductors are parallel to the axis, which emerges perpendicularly from the coil winding.
  • a manufacturing method known for coil windings made of strain-sensitive superconductors is based on the fact that the superconducting properties of the conductors of the coil winding are formed in their final shape only after the winding process (so-called "wind-and-react” technique, cf., for example, EP 1 471 363 A1), but this usually requires complicated winding devices which are not very suitable for cost-effective production of coil windings for replacement in rotating machines.
  • Object of the present invention is therefore to provide a saddle-shaped coil winding with the features mentioned, in which the above-mentioned problems are reduced.
  • a manufacturing method is to be specified which is suitable for producing non-planar coil windings using already finished band-shaped conductors such as high-T c superconductors, which are particularly sensitive to strain.
  • the saddle-shaped coil winding should consist of an Renner type spool shape may be formed on a tube shell surface such that it has axially extending, longitudinal side winding sections and winding end sections, which form winding ends forming therebetween, the windings of the coil winding
  • Winding center of the coil winding is arranged inclined, wherein the inclination angle is smaller in an inner turn than in an outer turn.
  • the length of a closed circulation by 360 ° of the superconductor to a winding center, z. B. understood a winding core.
  • the two edges of the strip each define a circumferential length.
  • these two circulating lengths are inherently the same.
  • the saddle coil is designed such that both circulating lengths in the case of the three-dimensionally shaped coil at most a difference of 0.4% (preferably 0.3% or even better 0.2%) change in length to the orbital lengths of the planar coil as well as relative to each other have.
  • This difference is dependent on the particular superconductor structure and its change in the superconducting properties during bending or stretching. It can therefore also be below the specified value. In this case, it is possible to ensure that the local elongation or compression of the strip conductor as compared to the flat coil is at most 0.4% (preferably 0.3% or even better 0.2%) over the entire circulation. This is necessary in order not to reduce the current carrying capacity of the strip conductor in the saddle coil.
  • the advantages associated with this embodiment of the coil winding can be seen in particular in that an effective field use of the superconducting material of already finished strip conductors can be achieved because the straight parts of the winding are in a range in which more power with the same quantitative use of strip conductor material can be achieved. In addition, a compact arrangement of the windings is made possible so that correspondingly smaller diameters of the area forming the pipe jacket surface can be achieved.
  • the coil winding according to the invention is also characterized in particular by the fact that its at least one conductor in the area of the end winding sections is inclined in a particular manner with its flat side inclined relative to a normal on the jacket surface in the direction of the winding center of the coil winding. With such an orientation of the conductor can be avoided that there is in the formation of the winding to excessive overstretching of the conductor.
  • the coil winding can be formed particularly advantageous with any strain-sensitive tape-shaped superconductor.
  • a strain-sensitive superconductor should be understood in this context to mean any prefabricated superconductor which, after its production, would be subjected to stretching or bending in a saddle coil according to known methods, which would lead to a marked deterioration of its superconducting properties, in particular its critical current density I c . by at least 5% over the unstretched one Condition would lead. A corresponding danger is given especially in the new oxide ceramic high-T c superconductors.
  • the coil winding may therefore preferably be formed with at least one high-T c superconductor with BPSCCO or YBCO material.
  • the at least one strip-shaped superconductor may also be formed with MgB 2 superconductor material.
  • the at least one strip-shaped superconductor for constructing the coil winding has an aspect ratio (width w / thickness d) of at least 3, preferably at least 5. It is precisely with such superconductors that coil windings with a pronounced saddle shape can now be produced without any fear of impairing their superconducting properties.
  • a tube with a circular or elliptical cross section, in particular a cylinder jacket surface can be formed.
  • the pipe jacket surface may be formed by a tubular body carrying the winding.
  • the coil winding may also be formed self-supporting. In the latter case, the pipe jacket surface is therefore only a fictitious, imaginary surface.
  • a tube with a curved axis can be formed, without it being necessary to come to unreasonable overstretching of the conductor. That is, the inventive measures are not limited to saddle coil windings with straight lateral winding sections.
  • the respective circumferential length in the saddle shape of the in the flat coil shape differs by at most 0.4%, preferably by at most 0.3%. Below this value, a degradation with respect to the superconducting properties of the conductor is not to be feared.
  • the coil winding has a radial height of at least 10% of the tube diameter to have a pronounced saddle shape.
  • the radial height is at least 30% of the pipe diameter.
  • the coil winding can be arranged in a rotating machine or in a magnet of an accelerator such as a gantry accelerator magnet or form part of this device. Namely, it is precisely for these devices that windings with a pronounced saddle shape are required.
  • the specified production method with the characteristics of winding a flat coil winding and subsequent shaping into a saddle coil winding has the advantages that the planar winding technique can be carried out in a simple manner.
  • Corresponding winding machines require only one axis of rotation.
  • more complex winder machines with at least two axes of rotation would be necessary for the direct production of bent saddle coil windings.
  • the method therefore enables a cost-effective winding production.
  • the method for producing a corresponding coil winding can additionally be configured as follows:
