Definitions
- the invention relates to a superconducting winding with at least one at least largely band-shaped HTS conductor, which is set in individual turns of the winding under a predetermined winding tension and on its outer side a reinforcing strip of a material with comparatively ⁇ higher tensile strength than that of the HTS conductor assigned ⁇ net.
- the invention further relates to a method for producing such a superconducting winding.
- a corresponding winding and a method for the production thereof can be taken from JP 10-92630 A.
- LTS material low-T c superconductor material
- HTS material high-T c -Supralei- termaterial
- the conductors are the so-called monocore or multifilament type, in an Ag matrix, one or more superconducting conductor ⁇ wires are embedded in the HTS material.
- 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, together with a Arm michs ⁇ band of an Ag alloy wound around a winding core.
- the material of the reinforcing strip has a greater tensile strength than that of the HTS conductor.
- 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 with the Merkma ⁇ len mentioned above should be designed so that the HTS conductor of Röbelleiter type is transposed with each other, at least largely band-shaped HTS single conductors and is the metallurgically not connected to the prefabricated end product of the HTS conductor Arm istsband be wound in the individual Lei ⁇ terwindungen under a higher winding tension than that of the HTS conductor.
- HTS cable ladder and the reinforcement or bandage band make it possible to manufacture universal HTS cable ladders for use with different mechanical loads.
- the choice of material for the armoring strip is then entspre ⁇ accordingly the requirements for operation of the winding.
- the reinforcing band introduced into the winding represents a local mechanical reinforcement of the winding and can thus absorb effectively occurring forces.
- winding according to the invention may additionally have the following features:
- the coils may be mechanically connected by means of a Kunststoffhar ⁇ zes.
- Corresponding synthetic resin impregnations prevent undesired conductor movements, which lead to a normal conduction (quenching) of the superconducting material.
- the windings must be spaced by insulation material to allow electrical flashover between adjacent windings, especially in one
- Insulating tape is advantageous when a thin in general ⁇ my insulation of the individual conductors is not sufficient.
- the HTS material of the individual conductors can be of the Bi-Cuprat type.
- the individual metallic components (Bi, Sr, Ca, Cu) of this type of material can be partially or completely substituted in a known manner by other elements.
- the HTS material of the individual conductors may also be of the Y cuprate type. Again, a complete or partial substitution of the metal ⁇ metallic components is possible.
- the individual conductors of both types of monocore or multi-material types tifilament type or of the coated carrier type (so-called coated conductors).
- the method for producing the superconducting winding emerge from the claims dependent on claim 11.
- the measures according to claim 11 with the measures of the dependent sub-claims or preferably also with those of several sub ⁇ claims can be combined. Accordingly, the method may additionally have the following features:
- a winding tension before ⁇ is seen • Preferred for the armoring strip which is at least l, 5-fold, preferably 3 times the winding tension for the HTS conductor. Only with the much larger winding tension on the Arm ists ⁇ band namely the unwanted spreading of Röbel ⁇ conductor is to be avoided.
- a winding tension of at least 10 MPa and at most 100 MPa is provided for the HTS conductor.
- FIG. 1 shows a structure for producing the winding from the outset
- FIG. 2 shows a detail of this winding
- the armoring strip is min ⁇ least, 5 times preferably wound around the 5 having a l, at least 3-fold greater winding tension than that of the HTS transposed conductor tangentially around the winding body.
- the winding tension WZ1 should be below the critical tensile stress 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.
- the tensile stress WZ2 for the reinforcing tape 5 is then for example 150 MPa.
- the width of which should correspond to the advantageous of the HTS transposed conductor 4 is practical as a material of each ⁇ table in question, which allows a sufficiently high winding tension in the said order. Examples are stainless steel strips or strips of a Cu alloy. Also suitably high tensile plastic materials are suitable, which are gege ⁇ where fiber-reinforced.
- the reinforcing strip can also be formed as a tissue, wherein the tissue parts are me ⁇ tallisch or made of plastic.
- FIG. 2 shows a cross section through the partially created winding according to FIG. 1.
- the winding has three windings w1 to w3, which are formed by co-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 ladder made of such individual conductors is generally my known (see the aforementioned WO 01/59909 Al 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.
