Definitions

  • the invention relates to a corresponding method and to the process enveloped high-T c superconductor.
  • HTS conductors with oxide high-T c superconducting material (HTS material).
  • HTS conductors which have a wire form (with a circular cross-section) and in particular a band shape (with rectangular cross-section) can be provided in an easy to be carried out process continuously with an insulating sheath.
  • the method should be suitable both for a single-conductor insulation as well as for the isolation of a HTS conductor structure in the form of a multi-conductor, which is composed of superconducting individual conductors, or a composite conductor with superconducting and normal conducting parts.
  • the so-called degree of stretching ie the stretching of the material
  • the stretching can advantageously take place under the simultaneous action of vacuum inside the tube. Together with an advantageous preheating of the conductor before the inlet into the guide channel and / or during the pulling of the conductor through this can thus produce a particularly good and bubble-free adhesive fit of the envelope on the superconductor.
  • the then taking place slow Ablung z. B. in air causes freezing and stress-free solidification of the melt from the insulating material on the conductor.
  • coating installations are known, by means of which insulating sheathings made of a thermoplastic material (see DE 26 38 763 A) by stripping nozzles, in pressure jacket or in the hose-stretching method (DE 24 09 655 A, 20 22 802 A, DE 21 10 934 A ) are to be applied to wires.
  • the wires can in this case consist in particular of steel (compare US Pat. No. 3,893,642), A1 (cf DE 24 09 655 A) or Cu (cf US Pat. No. 4,489,130 or the cited DE 21 10 934 A) and are generally circular cross-sectional areas.
  • the coating process to be carried out with such equipment is also referred to as extrusion coating.
  • a band shape of the superconductor of importance should be understood to mean any rectangular shape with angular or rounded edges.
  • the rectangular shape can have a relatively high aspect ratio, generally greater than 10, as is the case in particular with known thin HTS ribbon conductors.
  • the proposed method a continuous coating of a HTS conductor is possible, since the insulation material can be conveyed from a reservoir, which can be refilled at any time.
  • the thickness of the insulating sheath in a wide range is variable and adjust with sufficient accuracy. Since, for example, each individual conductor can be completely insulated, a double insulation security is given for strip conductor windings because the conductors are separated by a double insulation layer.
  • the mechanical and thermal property profile of the envelope can be adapted to the particular application by the use of different thermoplastic materials.
  • the proposed method is significantly faster than a conventional metallic Umspinnungs- or Lackiermaschine in metallic superconductors.
  • the lateral conductor edges are isolated, so that the risk of short circuits in this area is reduced.
  • the insulation is particularly suitable for thin band conductors with unfavorable aspect ratio. This eliminates the dreaded during painting process danger of a so-called "edge escape", i. an unwanted thick layer dilution in the range of edges with small edge radii, as they are given just with thin conductor strips.
  • the HTS conductor does not need to be mechanically stressed too much.
  • the mechanical load is limited to the low tensile forces generated by Leiterabwickler or -aufwickler. A conductor deflection during the coating process can thus be advantageously avoided.
  • thermoplastic materials are to be used with relatively low processing or melting temperature of less than 200 ° C and only a relatively short-term heating of the conductors are provided so as to a degradation of the superconducting properties (with respect to the critical temperature T c and in particular with regard to the critical current density J c to be measured in A / m 2, at least largely avoided.
  • Suitable thermoplastic materials for this purpose are polyethylenes, Polystyrene-ethylene-butylene elastomers, polyurethane elastomers, ethylene / vinyl acetate copolymers or acrylic acid / acrylate copolymers have been proposed.
  • insulating layer thicknesses of at least about 40 to 50 ⁇ m can be realized.
  • the insulating layer should be lower contrast.
  • a good adhesion of the insulating material on the conductor and a good connection of the corresponding insulating layer of impregnating and casting resins should be ensured.
  • Object of the present invention is therefore to propose a method which reduces the aforementioned difficulties.
  • special, enveloped by the process high-T c superconductors are given.
  • thermoplastics are in particular special engineering thermoplastics such as polyamides and polyesters and in particular high-temperature thermoplastics (HT thermoplastics) such as polyetherimide (PEI), polyethersulfone (PES), polysulfone (PSU), polyphenylene sulfone (PPSU) and polyetheretherketone (PEEK) suitable.
  • HT thermoplastics high-temperature thermoplastics
  • PEI polyetherimide
  • PES polyethersulfone
  • PSU polysulfone
  • PPSU polyphenylene sulfone
  • PEEK polyetheretherketone
  • HTS strip conductors in particular with filaments of Bi cuprate material and an embedding of the filaments in an Ag matrix, can withstand temperatures of at least 500 ° C. for several minutes without impairing their superconducting properties, in particular their current carrying capacity.
  • thermoplastics can be selected according to the invention.
  • inventively selected thermoplastics especially the HT thermoplastics PEI, PPSU and PEEK, have very good electrical and exceptionally good low temperature properties, ie, by good flexibility and toughness at low Distinguish temperatures.
  • other thermoplastics often show a strong tendency to embrittle at low temperatures.
  • thermoplastics proposed by the earlier application WO 00/11684 are improved adhesion adhesion to ceramic and metallic substrates to be achieved in the claimed temperature range due to the pronounced polar character of these materials and the significantly better compatibility and bonding to epoxide (EP) ) and unsaturated polyester resins (UP resins) used as potting and impregnating compositions for use of such superconductors.
  • EP epoxide
  • UP resins unsaturated polyester resins
  • thermoplastics to be selected according to the invention advantageously have a high modulus of elasticity (> 3000 MPa) at room temperature, a high surface hardness (Rockwell hardness ⁇ 120, R scale) and a low coefficient of friction ( ⁇ 0.6).
  • EVA ethylene vinyl acetate
  • modulus ⁇ 400 Mpa modulus ⁇ 400 Mpa
  • surface hardness Shore D ⁇ 40 surface hardness Shore D ⁇ 40
  • friction coefficient> 1 This mechanical and tribological property profile of the selected Thermoplastics also enable problem-free production of Roebelleitern.
  • a significant advantage of using the new insulating materials lies in the significant reduction of the insulating layer thickness. Due to the good processing properties of these plastics in the tube stretching process can allow insulating layer of the cladding of less than 100 ⁇ m, preferably in the range 15 to 30 ⁇ m and realize including, for example microns average thickness of not more than 30th This is essential to achieve a high effective current density in the conductor. Compared with the materials according to the previous application WO 00/11684, where preferably with a layer thickness of about 50 ⁇ is worked m, this is a reduction of the layer thickness of over 50%.
  • the combination of good processing behavior and the above-mentioned mechanical and tribological property profile enables the safe and problem-free production preferably of Roebelleitern with insulating layer thicknesses of 15 to 30 ⁇ m with high effective current density.
  • HTS conductor to which the method according to the invention is to be applied is here understood to mean not only a single conductor, but also a composition of several such conductors or parts of them.
  • the conductor can contain at least one conductor core made of the superconducting material.
  • An inventive coated with an insulating sheath superconductor can be used without additional insulation film. Thus eliminates caused by the co-winding insulation isolation effort.
  • casings with an approximately uniform thickness on all sides can advantageously be formed with the method according to the invention.
  • a designed outlet opening of the nozzle can provide that their spacing is uneven with respect to the conductor in its circumferential direction. In this way, in particular certain distances between adjacent conductors, for example within a conductor network or a winding can be determined.
  • the method according to the invention can just as well be used for wrapping band-shaped superconducting multiple or composite conductors.
  • Such conductors have a structure of a plurality of superconducting conductor parts or conductor regions, wherein at least one superconducting single conductor or such a conductor core are provided.
  • a corresponding structure can be particularly simply and evenly provided with an insulating sheath with the inventive method without the risk of affecting the conductor properties of the superconductor material.
  • the heating temperature should preferably be at least approximately the process temperature (permissible deviation: +/- 50 ° C).
  • Figures 1 and 2 show a nozzle of a system for carrying out the method according to the invention as a longitudinal section or in front view such as FIG. 3 shows a plant for the extrusion coating of a HTS conductor with a nozzle according to FIGS. 1 and 2.
  • a system to be provided for carrying out the method according to the invention is based on devices known per se, such as those used for coating non-superconducting wires with plastic materials by means of extrusion coating according to the so-called tube stretching method (see the aforementioned US 3,893,642 or the cited US Pat DE-A-2 022 802 and 21 10 934).
  • a corresponding system (see Figure 3) comprises a so-called extruder with extrusion head, which has an extrusion die, which is illustrated in Figures 1 and 2 in longitudinal section and in front view.
  • This nozzle generally designated 2 contains a guide channel 3 centrally through this channel, a superconductor 5 to be provided with an electrically insulating sheath 4 is to be guided in a direction of advance indicated by an arrow v by means of propulsion means (see FIG.
  • the superconductor 5 is a band-shaped HTS conductor. This conductor can advantageously be preheated prior to insertion into the guide channel 3.
  • the guide channel itself can be heated.
  • the insulating material of the envelope 4 is melted in the extruder (see FIG. 3), not shown, conveyed into the extrusion head with distribution system and pressed as a melt 6 into a die gap 7 of the extrusion die 2.

  • the distances (a1, a2) of the nozzle gap opening 8 from the strip conductor 5, their geometric configuration (w1, w2, R1, R2) and the advancing speed v of the conductor determine the contour of the envelope 4 and its thickness d.
  • the geometric design of the extrusion die can, as was assumed for the embodiment of Figure 2, are chosen so that the thickness d of the envelope 4 is about the same size on all sides.
  • a thickness d of less than 0.5 mm is planned, for example between 30 and 300 ⁇ m.
  • Deviating from it can by a Another design of the extrusion nozzle opening, for example a2 ⁇ a1 and w1 ⁇ w2, causes side lips to form on the narrow sides of the conductor. Such side lips can then be used as spacers in the manufacture of layer windings and thus make an additional co-winding of special spacers such as glass twine superfluous.
  • the contour of the outlet opening 8 of the nozzle gap may be structured such that a non-uniform thickness of the envelope results on at least one side of the conductor. In this way, for example, by means of a groove-like depression in the contour of the opening 8 to obtain a web-like bead of the envelope, which can then serve as a spacer. Furthermore, it is also possible, if appropriate, to disregard an exactly centric guidance of the superconductor through the guide channel 3 in order to produce a one-sided or two-sided stronger covering.
