Definitions
- the subject of the unpublished WO 00/11684 is a method for producing an all-round sheathing from an electrical insulating material made of plastic around at least one superconductor with high-T c -supralite material. According to this proposed method, a continuous encapsulation process is to be carried out at a process temperature which practically does not impair the superconducting properties of the conductor
- the conductor emerges from a guide channel extending in a direction of advance
- melt tube made of a melted thermoplastic insulation material in the direction of advance is extruded from a nozzle, the opening of which surrounds the conductor with all-round spacing, - With the advance of the conductor, the melt tube is stretched and pulled onto the surface of the conductor and the melt tube thus applied to the surface of the conductor is pulled through Cooling are solidified.
- This proposed method is intended in particular to be used to encase a ribbon-shaped superconductor with an aspect ratio of at least 3, preferably at least 10.
- HTS conductors that have a wire shape (with a circular cross section) and in particular a ribbon shape (with rectangular cross-section), can be continuously provided with an insulating covering in a simple process. The method is intended to be used both for cell insulation and for the isolation of a HTS conductor structure in the form of a multiple
- Conductor which is composed of superconducting individual conductors, or a composite conductor with superconducting and normally conducting parts.
- the casting package In order to ensure reliable insulation in these areas either, the casting package needs to be potted with casting resin or the use of insulating foils that are so wide that a short circuit between the conductors is prevented by a lateral protrusion of the foil beyond the respective conductor edges.
- the adjustment effort to enable parallel winding of the conductor and insulation film is relatively high.
- a covering made of thermoplastic insulation material is applied in thin-film extrusion.
- sion technology according to a so-called tube stretching process.
- a melt hose is extruded from a nozzle, which is larger in dimension than the conductor to be encased, which runs through a central guide channel in the middle of the nozzle.
- This creates a tube around the conductor which is stretched, ie stretched, by the advance of the conductor until the final, desired thickness (thickness) of the sheathing wall (insulation layer) is reached.
- This hose is pulled onto the conductor surface.
- Degree of stretching i.e. the stretching of the material, generally between 5 and 15.
- the stretching can advantageously be carried out under the simultaneous action of a vacuum in the interior of the hose. Together with an advantageous preheating of the conductor in front of the run in the guide channel and / or while the conductor is being pulled through it, a particularly good and bubble-free adhesive fit of the sheath on the superconductor can be produced.
- the slow Ah then z. B. in air causes freezing and stress-free solidification of the melt from the Isolationsmate ⁇ al on the conductor.
- This method consequently enables relatively thin (of a minimum thickness of approximately 40 ⁇ m and / or a maximum thickness of 100 ⁇ m) and flawless sheathing layers to be realized on superconductors with any cross-sectional shape, but in particular with a ribbon shape.
- Plastic material (cf. DE 26 38 763 A) is to be applied to wires by means of scraper nozzles, in pressure jacketing or in the tube stretching process (DE 24 09 655 A, 20 22 802 A, DE 21 10 934 A).
- the wires can in particular be made of steel (see US Pat. No. 3,893,642), Al (see DE 24 09 655 A) or Cu
- the proposed method is based on the knowledge that the aforementioned methods known per se are suitable for coating oxidic HTS conductors, the conductor-specific difficulties mentioned at the outset being able to be avoided. This is particularly important in the case of a ribbon shape of the superconductor.
- a band shape is understood to be any rectangular shape with angular or rounded edges.
- the rectangular shape can preferably have a relatively large aspect ratio generally above 10, as is particularly the case with known thin HTS strip conductors.
- the proposed method a continuous coating of a HTS conductor is possible, since the insulation material can be requested from a storage container that can be refilled at any time.
- the thickness of the insulating sheath can be varied over a wide range and with sufficient accuracy. put. Since, for example, each individual conductor can be completely insulated, double-layer insulation is provided for strip conductor windings because the conductors are separated by a double insulation layer.
- the mechanical and thermal property profile of the casing can be adapted to the respective application by using different thermoplastic materials.
- the proposed process is significantly faster than a conventional encapsulation or painting process previously used for metallic superconductors.
- the lateral conductor edges are isolated in the proposed method, thus reducing the risk of short circuits in this area.
- the insulation is particularly suitable for thin strip conductors with an unfavorable aspect ratio. This eliminates the fear of a so-called "edge alignment", i.e. an undesirable strong layer thinning in the area of edges with small edge radii, as is the case with thin conductor strips.
- the HTS ladder need not be subjected to excessive mechanical loads in the proposed method.
- the mechanical load is limited to the low forces generated by conductor unwinder or rewinder. A conductor deflection during the coating process can thus advantageously be avoided.
- thermoplastic materials with a relatively low processing or melting temperature of below 200 ° C are to be used and only a relatively short-term heating of the conductors is to be provided in order to reduce the superconducting properties (with respect to the critical temperature T ⁇ , and in particular with respect. m A / m 2 to be measured critical current density J c) at least largely avoided.
- Suitable thermoplastic materials for this are polyethylenes, Polystyrene-ethylene-3-butylene elastomers, polyurethane elastomers, ethylene / vinyl acetate copolymers or acrylic acid / acrylate copolymers are proposed.
- insulation layer thicknesses of at least about 40 to 50 ⁇ m can be achieved.
- the insulating layer should be less. It should be ensured that the insulation material adheres well to the conductor and that the corresponding insulation layer is well bonded to potion and casting resins. It turns out, however, that with the proposed insulation materials, for example, the production of so-called Roebel rods (cf. for example DE-PS 277012 or "Siemens Review", Vol.
- the object of the present invention is therefore to improve the proposed method with the features mentioned at the outset in such a way that the aforementioned difficulties are reduced.
- special uses of the method should be specified.
- the task relating to the method is achieved with the measures according to claim 1. Accordingly, the method for producing an all-round sheathing from an electrical insulating material made of plastic around at least one superconductor with oxidic high-T c -supralite material provides for a continuous sheathing process at a process temperature that does not practically impair the superconducting properties of the conductor the conductor emerges from a guide channel extending in a direction of advance,
- a melt tube is extruded from a melted thermoplastic insulation material in the tunneling direction from a nozzle, the opening of which surrounds the conductor with spacing from all sides,
- melt tube is stretched and pulled onto the surface of the conductor, and - the melt tube applied to the surface of the conductor is solidified by cooling.
- a thermoplastic material with a process temperature between 200 ° C and 500 ° C, preferably between 220 ° C and 450 ° C, should be provided as the insulation material.
- a process temperature which practically does not impair the superconducting properties of the conductor is understood to mean a temperature which at most leads to a degradation of the critical current density J c [in A / m 2 ] of less than 10%.
- thermoplastics include, in particular, special technical thermoplastics such as polyamides and polyesters, and in particular also high-temperature thermoplastics (HT thermoplastics) such as polyetherimide (PEI), polyether sulfone (PES), polysulfone (PSU), polyphenylene sulfone (PPSU) and polyether ether ketone ( PEEK).
- HT thermoplastics high-temperature thermoplastics
- PEI polyetherimide
- PES polyether sulfone
- PSU polysulfone
- PPSU polyphenylene sulfone
- PEEK polyether ether ketone
- HTS strip conductors in particular with filaments made of bi-cup material and an embedding of the filaments m, can withstand an Ag-Mat ⁇ x temperature load of at least 500 ° C. for several minutes without their superconductor properties, in particular their current carrying capacity, being impaired.
- the thermoplastics selected according to the invention in particular the HT thermoplastics PEI, PPSU and PEEK, have very good electrical and possess exceptionally good low-temperature properties, ie they are characterized by good flexibility and toughness at low temperatures. In contrast, other thermoplastics often show a strong tendency to become brittle at low temperatures.
- thermoplastics proposed with the earlier application are an 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 considerably better compatibility and application to epoxy (EP) ) and unsaturated polyester resins (UP resins), which are used as potting and drinking compounds for furnishings using such superconductors.
- EP epoxy
- UP resins unsaturated polyester resins
- thermoplastics to be selected according to the invention advantageously have a high Young's modulus (> 3000 MPa), a high surface hardness (Rockwell hardness>120; R scale) and a low coefficient of friction ( ⁇ 0.6) at room temperature.
- Young's modulus > 3000 MPa
- a high surface hardness Rockwell hardness>120; R scale
- a low coefficient of friction ⁇ 0.6
- EVA ethylene vinylate
- the insulating layer In the manufacture of tubular conductors, the insulating layer must ensure sufficient sliding capacity, since the individual conductors are combined to form a conductor assembly, for example by means of a bandage, with the individual conductors moving relative to one another. Due to the high coefficient of friction and the low surface hardness of the plastics listed in the earlier application, the individual conductors cannot slide against one another, and the insulation layer is deformed, which can lead to the insulation layer being torn open. A significant advantage of using the new insulation materials is the significant reduction in the insulation layer thickness.
- the combination of good processing behavior and the above-mentioned mechanical and tribological property profile enables the safe and problem-free manufacture of preferably Roebeleiter with insulating layer thicknesses of 15 to 30 ⁇ m with high effective current density.
- HTS leader to whom the method according to the invention is to be applied, is not only to be understood here as a single leader, but also as a composition / version of several such leaders or parts of them.
- the conductor can contain at least one conductor core made of the superconductor material.
- a superconductor transformed according to the invention with an insulating sheath can be used without an additional insulation film. This eliminates the manufacturing effort caused by winding insulation.
- the method according to the invention can advantageously not only be used to form envelopes of approximately uniform thickness on all sides. Rather, one can be designed in this way Provide opening of the nozzle so that its spacing with respect to the conductor m is seen unevenly in the circumferential direction thereof. In this way, particular distances between adjacent conductors can be defined, for example, within a group of conductors or a winding.
- the method according to the invention is particularly advantageously used for sheathing a ribbon-shaped superconductor with an aspect ratio of at least 3, preferably at least 10.
- Superconductors of this type in particular which can also only have a small thickness, are difficult to coat with known coating methods and only at the risk of the edge alignment mentioned.
- the method according to the invention can equally well be used for sheathing superconducting multiple or composite conductors.
- Such conductors have a structure consisting of a plurality of superconducting conductor parts or conductor regions, at least one superconducting individual conductor or such a conductor core being provided.
- a corresponding structure can be provided with the method according to the invention in a particularly simple and uniform manner with an insulating sheath without the risk of impairing the conductor properties of the superconductor material.
- These types of conductors can also have a strip shape.
- the heating temperature should preferably be at least approximately the process temperature (permissible deviation: +/- 50 ° C).
- FIG. 1 and 2 each schematically show a nozzle of a system for carrying out the method according to the invention as a longitudinal section or m front view
- FIG. 3 shows a system for extrusion coating an HTS conductor with a nozzle according to FIGS. 1 and 2.
- a corresponding system (cf. FIG. 3) comprises a so-called extruder with an extrusion head which has an extrusion nozzle which is illustrated in FIGS. 1 and 2 in longitudinal section or in front view.
- This nozzle generally designated 2 contains a guide channel 3 in the center.
- a superconductor 5 m to be provided with an electrically insulating sheathing 4 is moved to a direction of advance indicated by an arrow v with the aid of propulsion means (not shown) (see FIG. 3) to lead.
- the superconductor 5 is a band-shaped HTS conductor. This conductor can advantageously be preheated before being introduced into the guide channel 3. If necessary, the guide channel itself can be heated instead or in addition.
- the insulating material of the casing 4 is melted in the extruder (not shown) (see FIG. 3), m the
- Extrusion head with distributor system is required and a die gap 7 of the extrusion die 2 is printed as a melt 6 m.
- the gap width of which is significantly larger than the final thickness d of the sheathing 4 around the strip conductor 5 a melt tube 9 emerges in the direction of advance v, which is in the form of a stretching cone due to a fixation of its cone tip stretched on the strip conductor and applied to the conductor with the layer thickness d required on the strip conductor.
- a vacuum advantageously applied to the guide channel 3 generates a negative pressure in the interior of the stretching cone, which prevents the inclusion of air bubbles between the sheathing and the conductor and which, together with the preheating of the conductor, ensures that the sheathing 4 has a good fit on the conductor.
- the wrapped strip conductor is designated 5 'in FIG.
- the nozzle gap opening 8 advantageously has a shape adapted to the contour of the strip conductor 5.
- the thus largely rectangular opening with roundings at the corners is spaced apart by distances a1 and a2 with respect to the areas of the strip conductor and is defined by gap widths w1 and w2 and by radii of curvature R1 and R2m in their corner regions.
- the distances (a1, a2) of the nozzle gap opening 8 from the strip conductor 5, their geometric design (w1, w2, R1, R2) and the advance speed v of the conductor determine the contour of the sheathing 4 and its thickness d.
- the geometric design of the extrusion nozzle can, as was assumed for the exemplary embodiment according to FIG.
- the thickness d of the casing 4 is approximately the same on all sides.
- a thickness d of less than 0.5 mm is generally planned, for example between 30 and 300 ⁇ m.
- ne different design of the extrusion nozzle opening for example a2 ⁇ al and wl ⁇ w2 can cause 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 additional winding of special spacers such as glass twine unnecessary.
- the contour of the opening 8 of the nozzle gap can also be structured such that a non-uniform thickness of the sheath results on at least one side of the conductor.
- a web-like bead of the covering can be obtained, which can then serve as a spacer. Furthermore, it is also possible, if necessary, to dispense with an exactly centric guidance of the superconductor through the guide channel 3 in order to produce a sheath that is thicker on one or two sides.
- Suitable insulating plastic materials for the sheathing 4 are all thermoplastic materials which on the one hand have a processing or melting temperature, which precludes impairment of the superconducting properties of the HTS conductor 5 to be sheathed, and yet a sufficient plasticity for the extrusion coating process
- known HTS strip conductors with filaments made of bi-cup material, which are embedded in an Ag matrix can withstand temperature loads of over 500 ° C. for several minutes without their superconducting properties
- a corresponding specific KTS standard ribbon conductor which is the basis for the following considerations, has been removed
- thermoplastic materials are preferably chosen for such a HTS strip conductor, the processing temperature of which is above 200 ° C. and can be a maximum of 500 ° C. Materials which enable processing in a temperature range between 220 ° C. and 450 ° C., in particular between 240 ° C. and 420 ° C., preferably between 250 ° C. and 380 ° C., are advantageously selected. The selection of thermoplastics for this temperature range is particularly large.
- suitable materials are, in particular, known technical thermoplastics from the family of polyamides or polyesters, which should preferably be provided for the lower part (approximately between 200 ° C. and 290 ° C.) of the temperature range mentioned.
- HT high-temperature thermoplastics
- PES polyether sulfone
- PSU polysaleton
- PPSU polyphenylene sulfone
- PEEK polyether - etherketon
- thermoplastic insulation materials are additionally carried out from the point of view that the thermoplastics used have sufficiently good low-temperature properties so that failures under operating conditions and / or during cooling and warming-up processes can be excluded.
- the insulating sleeve can additionally be colored with dyes. This enables easy visual control of the casing.
- the thin-layer extrusion coating method according to the invention is particularly suitable for covering tape-shaped HTS conductors whose conductor tape thickness is less than 1.5 mm, preferably less than 0.5 mm, and which have a high aspect ratio of at least 3, preferably at least 10 ,
- a corresponding HTS ribbon conductor can, for example, have a width of 3.6 mm and a thickness of 0.25 mm, and in particular can be the aforementioned HTS standard ribbon conductor.
- bi-cuprate materials that mainly include the so-called 2212 phase (80 K phase) or preferably the so-called 2223 phase (110 K-
- the Bi-Cuprat material can additionally contain Pb (so-called "BPSCCO").
- Band-shaped HTS conductors with envelopes sm ⁇ created in accordance with the invention mostly also provided with an additional ceramic surface coating, which prevent the actual metallic outer sides or surfaces of the conductor from becoming messy, which preferably consist of Ag or an Ag alloy such as AgMg, while preventing the need for reaction annealing should.
- FIG. 3 A corresponding coating system is indicated in FIG. 3.
- This system has the following parts in succession in the direction of tape guidance v, namely an unwinding device (so-called “unwinder”) 14, from which the HTS tape conductor 5 to be coated is unwound, a felt brake 15, an N 2 - Shielding gas purging 16 to avoid oxidation, a non-contact inductive conductor heating 17 to at least approximate the conductor to the processing temperature of the used thermoplastic insulation materials such as, for example, heating from a thermoplastic polyurethane elastomer, an extrusion coating device (so-called “extruder”) 18 with refill nozzle 19 for the thermoplastic insulating material, an extrusion head with built-in extrusion nozzle 2, an air shower 20, several guide rollers 21 ⁇ , a pore detector 22 for monitoring the applied covering,
- the thickness d of the casing can also be influenced by the choice of a suitable tape pulling speed. For example, with a conductor throughput speed of approximately 5 m / mm, a sheath of approximately 30 ⁇ m thickness can be produced.
- the conductor is ductile preheated by means of the conductor heater 17, in particular at least approximately at a temperature level close to the processing temperature (ie possibly slightly above or below it, for example +/- 50 ° C.).
- This preheating of the conductor which is required only for a short time and therefore does not damage the superconductor material, is advantageously carried out under a protective gas atmosphere in order to avoid oxide formations on the conductor surface, which can have a negative effect on the adhesion of the insulating covering layer to the conductor.
- a possible preheating of a conductor is indeed known in principle; however, the preheating temperatures used so far are significantly lower than the processing temperatures of the selected thermoplastics that are to be provided for HTS conductors. For a really good adhesive bond To ensure the insulation material on the conductor, it is advisable to preheat the conductor to a temperature as high as possible, at which HTS conductor damage with regard to its superconducting properties does not yet occur.
- thermoplastic melt strikes an insufficiently preheated conductor, this could otherwise lead to undesired immediate freezing and solidification of the melt on the contact surface; and this would prevent adequate wetting of the conductor surface by the melt.
- good wetting is a prerequisite for the formation of adhesion liability. This liability is supported by the negative pressure mentioned in the stretching cone.
- the air nozzles of the air shower 20 attached behind the extruder 18, a countercurrent cooler which may still be present, and the blower 23j serve for faster cooling and solidification of the applied coating layer made of the thermoplastic insulating material.
- a non-destructive pore detector 22 for example, a laser arrangement 24. Due to the rapid cooling and solidification of the sheath, the sheaths can stick together when the conductor 5 'is subsequently wound up the rewinder 26 can be prevented.
- a separating layer for example made of paper, can be wound there with the conductor on the rewinder 26 serving as a supply spool, in order to prevent the conductor from sticking during storage there.
- the coating of the conductor can be provided with a powder suitable for this purpose, for example of talc.
