- HTS conductors of the second generation are compounds of the type REBa 2 CU30 x, where RE stands for a rare earth element Ele ⁇ or a mixture of such elements.
- the substrate tape is typically either steel or alloy Hastelloy.
- the electrical contact to an external circuit is usually made via a contact layer of copper, wherein this contact layer is either applied on one side over the superconducting layer or can surround the entire band conductor as an enveloping layer. In both versions, it is better to contact on the Side of the substrate strip, which carries the superconducting layer. This page of the strip conductor is referred to below as the contact page.
- a wet winding process used with an epoxy adhesive then must first a filler, for example, Teflon, to hold the free position to be contacted by adhesive ⁇ medium. After removal of the filler can be made for contacting this point, for example, a solder joint to a contact piece of copper. However, since this contact is located within the coil, the contact area needs to Her ⁇ position of the necessary mechanical stability subsequently be fixed with bandages made of glass fiber reinforced plastic and epoxy adhesive.
- Object of the present invention is to provide a coil device which avoids the disadvantages mentioned. Another object is to provide a method for producing such a coil device.
- the coil device comprises at least one coil winding with at least one winding of at least one superconducting strip conductor.
- the strip conductor has a first conductor surface, which is designed as a contact side and is provided with a contact layer.
- the strip conductor is twisted about a longitudinal axis of the strip conductor within at least one turn in a Torsionsbe ⁇ rich by about 180 degrees, and the contact side of the strip conductor faces on an inner side of the winding to a center of the winding and facing away on an outer side of the winding from the center of the winding ,
- the torsion of the strip conductor about its longitudinal axis within ⁇ half of the coil winding is achieved that, for a simp ⁇ chen winding consists typically of a plurality of flat superposed turns on both the inside of the winding and on the outside of the winding, the side of the tape conductor to the low-resistance contact to supralei ⁇ border layer comes to lie outside.
- the superconducting coil means HTS-Mate rials include the second generation, in particular the compounds of the type REBa above 2 x CU30.
- Second-generation HTS materials are also advantageous because they have a higher tensile strength and a higher critical current density than ⁇ HTS materials of the first generation.
- the entire coil winding may be formed with either one or more parallel superconducting conductive tracks which may extend over the entire radial area of the coil winding.
- the individual strip conductors of the stack can either be twisted one at a time or they can be twisted as a whole in the form of the entire stack.
- mechanical problems can be avoided. For example, a bending of the strip conductor within the winding can be avoided, and the durability of the entire superconducting coil device is not endangered by the possible wear of an additional inner solder joint.
- the coil device according to the invention comprises a coil winding with a plurality of turns, but also applications are possible in which the advantage according to the invention of the torsion of the strip conductor already comes into play in a single turn.
- a superconducting strip conductor is wound in several turns on a winding support.
- the strip conductor has a first conductor surface, which is designed as a contact side and is provided with a contact layer. The contact side of the strip conductor is at the beginning of the winding to the winding support and thus facing a center of the winding.
- the strip conductor is twisted about at least one of the turns in a torsion about 180 degrees about a longitudinal axis of the strip conductor, and the contact ⁇ side of the strip conductor is remote on an outer side of the winding from the center of the winding.
- the advantages of the manufacturing process are partly analogous to the advantages of the superconducting coil device according to the invention. Further advantages are in the simplified manufacturing process compared to the production of a coil device with an additional inner contact for changing the orientation of the strip conductor. In a twist of the strip conductor by torsion, on the one hand, the additional process step for producing the inner contact connection is avoided.
- the winding can be carried out with a higher winding tension, if no mechanically sensitive rather internal soldering contact is present. As a rule, the winding process can also be carried out more easily and faster if only a single strip conductor or a package of parallel strip conductors has to be wound without additional internal soldering contact.
- the coil device may additionally comprise the following features:
- the superconductive coil device may comprise a first contact between the contact side of the strip conductor and an inner contact piece on an inner side of the coil winding and a second contact between the contact side of the Bandlei ⁇ ester and an outer contact piece on an outer side of the coil winding.
- the inside of the Spu ⁇ lenwicklung faces a center of the coil winding, and the outer side of the coil winding facing away from the center of the coil winding.
- the first and second contacts with the inner and outer contacts serve to connect the coil means to an external circuit.
- these contacts are made as low as possible, and the contacts suitably comprise conductive materials as possible with a high geometric cross section for the
- the inner and outer contacts may comprise copper.
- the advantage of this embodiment is that in this way the contacts to the two contact pieces can be created on freely accessible sides of the coil winding. In contrast to
- Shrinkage between the material of the placeholder and the remaining materials of the coil winding when cooling the coil winding to operating temperature can be caused.
- Another advantage of the freely accessible contact points to create the contacts to the contact pieces is that under less confined space conditions a sufficiently low-resistance and reliable solder joint zwi ⁇ ⁇ contact piece and contact side of the strip conductor can be created easily.
- a further power supply from an external circuit to the contact pieces is simplified because the contact pieces can be easily connected to an external power connection even on the freely accessible sides of the coil winding.
- the strip conductor can have two conductor surfaces
- the coil device can comprise at least two filler pieces, which are arranged adjacently in the torsion region of the at least one twisted turn in each case one of the conductor surfaces of the strip conductor, so that the filler pieces through the
- the advantage of this embodiment is that the mechanical stability of the resulting ⁇ coil winding is increased, since the band conductor is held firmly by the at least two filler pieces.
- the mechanical stability is specific for a ⁇ increased during the winding of the coil, so that during the manufacture, a greater winding tension can be used without the strip conductor in the region of the torsion onszone damage.
- the mechanical stability during operation of the superconducting coil is also improved by the filler pieces.
- Superconducting coils can be exposed during their operation strong centrifugal forces, for example by rotation in generators or machines. Alternatively or additionally, they may also be exposed to high Lorentz forces when generating strong magnetic fields.
- Each of the two above-mentioned filler may be an inner and an outer portion comprising, the respective inner section is arranged on a local side facing the center side of the twisted ribbon conductor and arranged the respective äuße ⁇ re portion on a locally remote from the center side of the twisted ribbon conductor is.
- Such a division of the filler in at least two Sectionstü ⁇ bridge is advantageous because the two conductor surfaces of the strip conductor change by the torsion in each case from the inside to the outside or vice versa.
- the dividing each patch into at least two sections facilitates the insertion in the winding to be produced.
- the torsion range of the winding can be at least three times as large along the longitudinal direction of the strip conductor as the width of the strip conductor. Particularly advantageously, the torsion range in this direction at least five times and at most ten times as large as the width of the Bandlei ⁇ age .
- the torsion of the strip conductor is narrower, and the individual layers of the strip conductor are subjected to greater mechanical stress by the torsion.
- the advantage of a rather small aspect ratio ⁇ is that the compactness and any existing symmetry of the entire coil device is disturbed only in a small portion. It is therefore advantageous to choose the torsion zone as small as it is possible in the mechanical strength of the strip conductor used.
- the coil winding may comprise at least five turns, and the at least one twisted winding may in the region of the 20% facing away from the center of the strip conductor and in the direction of Leitererbrei ⁇ te about the same size or almost as large Turns lie.
- the number of turns is advantageously substantially higher, for example in the range of 10 to 1000 turns.
- a large part of the coil winding ⁇ maintain a most advantageous symmetrical structure that is disturbed only on a small portion on the outside of the winding by the torsion.
- the torsion region of the twisted turn may be approximately diametrically opposite the region of the first contact. This is advantageous in order to avoid the damage caused by the first contact and torsion.
- the coil winding can be designed as a flat rectangular coil with four straight sections and four rounded corners.
- a rectangular coil or racetrack coil ge ⁇ called coil shape is often used in the field of rotors of generators or synchronous machines.
- other coil shapes are possible, such as oval or cylindrical flat coils or saddle-shaped coils.
- the torsion region can be arranged centrally on one of the straight sections of the rectangular coil.
- This arrangement has the advantage that the band conductor in the torsion region is then twisted only along the longitudinal axis and at this point is not simultaneously bent within the winding plane. If there is a torsion at the same point and at the same time bending around another axis, the band conductor is subjected to more stress than a simple torsion on a straight section of the winding.
- An advantage of the uniform distribution of the torsional stress is an arrangement of the torsion region in the middle of one of the straight sections of the rectangular coil.
- Be ⁇ Sonders is arranged at a dung provided for a rotating application of the torsion coil at or near the intended axis of rotation of the coil is advantageous.
- Such an embodiment has the advantage that occur due to the positioning on or near the axis of rotation only low centrifugal forces in the area of the Be ⁇ torsion zone, and that thus the mechanically somewhat more vulnerable twisted portion of the ribbon conductor is protected from additional mechanical stresses.
- the turns of the coil winding may be mechanically fixed with a potting compound and / or an adhesive.
- the resulting benefits are analogous to the advantages of using patches to fill in the cavities created by the torsion.
- the coil winding is ⁇ before damage by mechanical force protected.
- Particularly advantageous is the use of Guang ⁇ pieces in combination with a casting of the coil winding, wherein the inserted filler is cast together with the adjacent Bandleiterwindept.
- a first contact between the contact side of the strip conductor and an inner contact piece can be formed only after the winding of the strip conductor, and a second contact between the contact side of the strip conductor and an outer contact piece can be formed.
- This embodiment is advantageous if the coil is to be released from the winding carrier before it is put into operation and is either used as a freely supporting component without a carrier or is transferred to a separate coil carrier for operation.
- at least two filler pieces can be arranged adjacent to one of two conductor surfaces of the strip conductor in such a way that they cause interspaces due to the torsion between adjacent turns fill.
- Each of the two filler pieces may comprise an inner and an outer portion, wherein the respective inner portion is disposed on a locally centered side of the twisted strip conductor and the respective outer portion is arranged on a side facing away from the center of the twisted band conductor locally.
- the advantage of sol ⁇ chen segmentation of the filler lies in the ease of insertion of the portions during winding of the coil, since the total of at least two individual sections during the gradual twist and during the progressive winding of the twisted coil can be introduced into the nascent successively interstices ,
- the coil winding can be glued after winding and / or during winding with a potting compound and / or with a Klebemit ⁇ tel.
- the advantages of these embodiments are analogous to the advantages of claim 9.
