Description

Titel: Spule zum Erzeugen eines MagnetfeldesTitle: Coil for generating a magnetic field
Die Erfindung betrifft eine Spule zum Erzeugen eines Magnetfeldes mit wenigstens einer aus einem Supraleiter gefertigten, m einen Kunststoff eingegossenen Wicklung, wobei ein am Umfang der Wicklung angeordnetes Wicklungsende als eine Kontaktierung für einen elektrischen Leiter dient.The invention relates to a coil for generating a magnetic field with at least one made of a superconductor, m cast a plastic winding, wherein a arranged on the circumference of the winding winding end serves as a contact for an electrical conductor.
Spulen mit einer aus einem Supraleiter gefertigten Wicklung kommen im Motor-, Generator- und Magnetbau zum Einsatz, falls die Vorteile des geringen Widerstands von gekühlten Supraleitern ausgenutzt werden sollen. Häufig werden Hochtemperatur-Supraleiter eingesetzt, die aus einem spröden Komposit aus Keramik und Metall bestehen, aber selbst bei Zimmertemperatur und insbesondere bei tieferen Temperaturen keine großen Zug- oder Scherkräfte aufnehmen können. Außerdem verlieren Supraleiter durch die Kühlung ihre bei Zimmertemperatur bereits geringe Elastizität weiter. Bei der Montage der Spulen wird das Wicklungsende meist durch Anlöten eines metallischen oder supraleitenden Leiters kontaktiert. Auf den angelöteten Leiter übertragene Zug- und Querkräfte können die Wicklung beschädigen, wodurch bei einem unvorsichtigen Umgang mit der Kontaktierung die Wicklung im schlimmsten Fall zerstört werden kann.Coils with a winding made of a superconductor are used in motor, generator and magnet construction, if the advantages of the low resistance of cooled superconductors are to be exploited. Often high-temperature superconductors are used, which consist of a brittle composite of ceramic and metal, but even at room temperature and especially at lower temperatures can not absorb large tensile or shear forces. In addition, superconductors lose their cooling at room temperature already low elasticity on. When mounting the coils, the coil end is usually contacted by soldering a metallic or superconducting conductor. Tensile and shear forces transmitted to the soldered conductor can damage the winding, which can damage the winding in the worst case if the contact is handled carelessly.
Aufgabe der Erfindung ist es, Spulen mit Wicklungen aus Supraleitern zu schaffen, die bei einfacher Herstellung eine robuste Kontaktierung ermöglichen und bei denen ein verringertes Risiko der Beschädigung der Wicklung besteht.The object of the invention is to provide coils with windings of superconductors, which allow a simple contact with a robust contact and where there is a reduced risk of damage to the winding.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Kontaktierung ein elektrisch leitfähiges Anschlussstück mit einem flächig mit dem Wicklungsende verbundenen Fußbereich und einem Kopfbereich zum Anschließen des Leiters aufweist, wobei der Fußbereich in radia- ler Richtung teilweise von einer in den Kunststoff eingegossenen, die Wicklung zumindest teilweise umgreifenden Verstärkungsemlage überdeckt ist. Dies hat den Vorteil, dass das Anschlussstück gegenüber der Wicklung durch die in den Kunststoff eingegossene Verstärkungsemlage stabilisiert ist. Gegebenenfalls an dem Anschlussstück angreifende Kräfte werden durch die Verstärkungsemlage großflächig auf den die Spule umhüllenden Kunststoff übertragen, wodurch insbesondere das Wicklungsende von diesen Kräften entlastet ist.This object is achieved in accordance with the invention in that the contacting has an electrically conductive connecting piece with a foot region connected in a planar manner to the winding end and a head region for connecting the conductor, wherein the foot region is in radia- The direction is partially covered by a cast in the plastic, the winding at least partially embracing reinforcing layer. This has the advantage that the connection piece with respect to the winding is stabilized by the reinforcing layer cast into the plastic. Optionally acting on the connector forces are transmitted over a large area by the reinforcing pad on the plastic enveloping the coil, whereby in particular the winding end is relieved of these forces.
Vorzugsweise umgreift die Verstärkungsemlage ergänzt mit dem Anschlussstück die Wicklung vollständig, wodurch lokale Druck- und Zugbelastungen an der Wicklung verhindert werden. Die Verstärkungsemlage und das Anschlussstück bilden vorzugsweise eine in sich geschlossene Zugentlastung. In einer vorteilhaften Ausführung besteht die Verstärkungseinlage aus einem die Wicklung umgreifenden Ring, wie insbesondere einem vorgefertigten, ausreichend stabilen Band o- der geteilten Ringkörper.Preferably, the reinforcing pad complements the fitting completely surrounds the winding, whereby local compressive and tensile loads on the winding can be prevented. The reinforcement pad and the connector preferably form a self-contained strain relief. In an advantageous embodiment, the reinforcing insert consists of a winding surrounding the ring, such as in particular a prefabricated, sufficiently stable band o of the divided annular body.
Gemäß einer vorteilhaften Ausgestaltung, kann der Fußbereich an beiden gegenüberliegenden Querseiten Schenkel aufweisen, wodurch der Fußbereich großflächig am Wicklungsende anliegen kann und auch die Verstärkungseinlage die Schenkel an dem Wicklungsende großflächig überdecken kann. Diese Schenkel können in Umfangsrichtung über die Querseiten des Anschlussstücks im Kopfbereich hinausragen. In einer besonders vorteilhaften Ausgestaltung überdeckt die Verstärkungseinlage dann beide Schenkel und erstreckt sich am Umfang einer Außenwindung der Wicklung entlang von einem zum anderen Schenkel, wodurch eine Umreifung der Wicklung entlang des Umfangs entsteht. Durch diese Umreifung ist die Spule am Umfang der Wicklung vor Stößen geschützt. In einer alternativen Ausgestaltung können zwei Verstär- kungsemlagen quer zur Wicklung angeordnet sein, die je einen der Schenkel quer überdecken und anschließend die Wicklung seitlich an Vorder- und Rückseite umgreifen. Die Verstärkungseinlagen können dann vorzugsweise einen Wickelkörper, auf den die Wicklung aufgewickelt ist, durchfassen, um die Wicklung vollständig zu umgreifen. Die Verstärkungseinlage kann alternativ an dem Wickelkörper befes- tigt sein, sodass das Anschlussstück über die Verstärkungseinlage an dem Wickelkorper abgestutzt ist.According to an advantageous embodiment, the foot region may have legs on both opposite transverse sides, as a result of which the foot region can lie over a large area at the end of the winding and also the reinforcing insert can largely cover the legs at the end of the winding. These legs can protrude in the circumferential direction over the transverse sides of the connecting piece in the head area. In a particularly advantageous embodiment, the reinforcing insert then covers both legs and extends along the circumference of an outer turn of the winding along one to the other leg, whereby a strapping of the winding is formed along the circumference. As a result of this strapping, the coil is protected against impact at the circumference of the winding. In an alternative embodiment, two reinforcing layers can be arranged transversely to the winding, each covering one of the legs transversely and then laterally encompassing the winding on the front and rear side. The reinforcing inserts can then preferably pass through a winding body, on which the winding is wound, in order to completely encompass the winding. The reinforcing insert may alternatively be attached to the winding body. be so that the connector is truncated on the reinforcing insert on the winding body.
Unabhängig von der Anordnung der Verstarkungseinlage an der Wicklung ist es vorteilhaft, wenn die Verstarkungseinlage in wenigstens eine Ausnehmung zwischen dem Kopfbereich und dem Fußbereich insbesondere formschlussig einfaßt, wodurch das Anschlussstuck ebenfalls stabilisiert ist Das Anschlussstuck kann an beiden Querseiten jeweils eine nutformige Ausnehmung aufweisen, in welche die Verstarkungseinlage, falls sie sich entlang des Umfangs erstreckt, mit beiden Stirnseiten emfasst oder durch welche sie hindurchgreift. Falls zwei Verstar- kungsemlagen an der Vorder- und Rückseite quer zu der Wicklung angeordnet sind, können diese seitlich in die Ausnehmungen einfassen. Die Verstärkungseinlage kann zusatzlich in den Ausnehmungen festgeklemmt sein.Regardless of the arrangement of the reinforcing insert on the winding, it is advantageous if the reinforcing insert engages in particular form-fitting manner in at least one recess between the head region and the foot region, whereby the connection piece is also stabilized. The connection piece can each have a groove-shaped recess on both transverse sides, into which the reinforcing insert, if it extends along the circumference, embeds with or passes through both end faces. If two reinforcing layers are arranged at the front and rear side transversely to the winding, they can be laterally enclosed in the recesses. The reinforcing insert may additionally be clamped in the recesses.

Diese auch als "Doublepanca- ke-Spulen" bezeichneten Doppelscheibenspulen haben den Vorteil, dass die Kontaktierung am leicht zugänglichen Umfang erfolgt Die beiden Anschlussstücke sind zweckmäßig parallel zueinander und durch einen Spalt voneinander isoliert angeordnet. In dem Spalt kann weiter zweckmäßig eine Isolierschicht angeordnet sein.The plastic is preferably a Elektroimpragnierungs- or a potting compound.

The two connection pieces are expediently arranged parallel to one another and isolated from one another by a gap. In the gap may be further suitably arranged an insulating layer.

Beim Verlöten des Fußbereichs mit dem Wicklungsende wird vorzugsweise ein Lot mit einer hohen Schmelztemperatur verwendet. Em Leiter kann dann mit einem Lot niedrigerer Schmelztemperatur an den Kopfbereich angelötet werden, ohne dass ein Schmelzen des Lotes am Fußbereich auftreten kann Für das Lot am Kopfbereich kann bspw handelsübliches Elektroniklot verwendet werden.The winding is preferably made of a high-temperature superconductor, which has the advantage that the coil can be cooled with nitrogen - without being limited to it.

For example, commercially available electronic solder can be used for the solder on the head area.
