LeiteranordnungConductor arrangement
Die Erfindung betrifft eine Leiteranordnung für ein supralei¬ tendes Gerat .The invention relates to a conductor arrangement for a supralei¬ ting device.
Hochstromsysteme, insbesondere Stromschienensysteme für Nie¬ derspannung, werden m der Regel mit minimalen Reaktanzen ausgeführt, um die auf eine Längeneinheit bezogenen Span- nungsabfalle klein zu halten. Aus Gründen der elektromagneti¬ schen Verträglichkeit (EMV) wird zusätzlich das magnetische Außenfeld m der Umgebung des Hochstromsystems minimiert. Derartige Hochstromsysteme sind in der Regel als Drehstromsy- steme ausgeführt.High-current systems, in particular busbar systems for low voltage, are generally implemented with minimal reactances in order to keep the voltage drops related to a unit length small. For reasons of electromagnetic compatibility (EMC), the magnetic external field m around the high-current system is also minimized. Such high-current systems are usually designed as three-phase systems.
Für die Einfuhrung der supraleitenden Technik für derartige Hochstromsysteme stehen für Wechselstrom geeignete metalli¬ sche Supraleiter in Form von Runddrahten oder Runddraht-Bun- dein mit Bundeldurchmesser bis zu 1,5 mm zur Verfugung. Auch die fortschreitende Entwicklung bei keramischen Supraleitern zeigt eine Tendenz zu Runddrahten vergleichbarer Durchmesser auf .Metallic superconductors suitable for alternating current in the form of round wires or round wire bundles with bundle diameters of up to 1.5 mm are available for the introduction of superconducting technology for such high-current systems. The progressive development of ceramic superconductors also shows a tendency towards round wires of comparable diameters.
Ein Hochstromsystem mit Runddrahten erfordert eine Vielzahl parallelgeschalteter Drahtbundel je Phase. Der zulassige Be¬ triebsstrom für ein 1, 5-mm-Bündel betragt beispielsweise etwa 250 A. Um eine gleichmäßige Stromaufteilung auf die paralle¬ len Zweige zu erreichen und gleichzeitig die oben genannte Forderung nach Minimierung der Reaktanzen und des magneti¬ schen Außenfelds zu erfüllen, sind zusätzliche Maßnahmen er¬ forderlich.A high-current system with round wires requires a large number of wire bundles connected in parallel per phase. The permissible operating current for a 1.5 mm bundle is, for example, about 250 A. In order to achieve a uniform current distribution between the parallel branches and at the same time to meet the above-mentioned requirement for minimizing the reactances and the magnetic outer field , additional measures are required.
Bei bisherigen normalleitenden HochstromsySternen, msbeson- dere Schienensystemen, werden Kupfer- oder Aluminium-Flach- leiter in Sandwich-Bauweise verwendet . Dabei sind die drei Phasenleiter und gegebenenfalls ein zusätzlicher NulleiterIn the case of previous normal-conducting high-current stars, especially rail systems, copper or aluminum flat conductors in sandwich construction are used. The three phase conductors and possibly an additional neutral conductor

The round wires or round wire bundles are assembled in the phase sequence U, V, W, N, U, V, W, N ... (4-wire system) or, for example, U, V, W , U, V, W ... (3-wire system) connected, so that a large number of three-phase systems connected in parallel are created.
Die Gewebestruktur der Leiteranordnung 1 bietet einem flussi- gen Kühl- und Isoliermittel genügend Benetzungsmoglichkeiten für die supraleitenden Runddrahte oder Runddrahtbundel . Als Kühl- und Isoliermittel kommen bevorzugt Helium, Wasserstoff oder Stickstoff ( j e nach Sprungtemperatur) zur Anwendung.The fabric structure of the conductor arrangement 1 offers a liquid coolant and insulating agent sufficient wetting options for the superconducting round wires or round wire bundles. Helium, hydrogen or nitrogen (depending on the transition temperature) are preferably used as cooling and insulating agents.
Die Durchmischung oder Reihenfolge der Phasenleiter ergibt eine gleichmäßige Stromverteilung auf die Parallelzweige, ei¬ ne minimale Gesamtreaktanz und kleinste magnetische Ruttel- krafte auf die Supraleiter.The mixing or sequence of the phase conductors results in a uniform current distribution on the parallel branches, a minimal overall reactance and minimal magnetic vibratory forces on the superconductors.
Falls erforderlich kann durch Harzimpragnierung der isolie¬ renden Faden und einer entsprechenden Wärmebehandlung der fertig montierten Leiteranordnung (Ausbacken) eine zusätz¬ liche Verklebung und Härtung erzielt werden, ohne daß der Durchtritt des Kühlmittels spater behindert ist.If necessary, additional impregnation and hardening can be achieved by resin impregnation of the insulating threads and a corresponding heat treatment of the assembled conductor arrangement (baking), without the passage of the coolant being hindered later.
In der Zeichnung ist mit d der Drahtbundeldurchmesser und mit t die Teilungsbreite einer Parallelgruppe bezeichnet. Die Teilungsbreite kann beispielhaft im Bereich von 10 mm liegen.In the drawing, d is the wire bundle diameter and t is the pitch of a parallel group. The division width can, for example, be in the range of 10 mm.
Der Durchmesser der verwendeten Drahte oder Runddrahtbundel, die Anzahl der erforderlichen Parallelzweige und die notwen¬ digen Isolationsabεtande zwischen den leweiligen Phasenlei- tern bestimmen die Gesamtgewebebreite.The diameter of the wire or round wire bundle used, the number of parallel branches required and the necessary insulation distances between the respective phase conductors determine the overall fabric width.
