Description

  

   <Desc/Clms Page number 1> 
    Supraleitender      Transformator   Die Erfindung betrifft einen elektrischen Transformator mit    Wicklungen   aus    Baustoffen,   die auch    be1   hohen magnetischen Feldstärken    supraleitend      bleiben.   



  Das Verschwinden des elektrischen Widerstandes bei tiefsten Temperaturen    (d.h.   die    Supraleitung)   ist schon seit längerem bekannt. Sie konnte jedoch für Zwecke der Starkstromtechnik, beispielsweise beim Bau von Erregerspulen elektrischer    Transformatoren   oder Maschinen, nicht angewendet werden,    weil      dne   bis in die jüngste Zeit hinein    bekannten      Materialien   die Eigenschaft der    Supraleitung   schon    in   geringen magnetischen Feldern verlieren. 



     In   neuester Zeit ist es jedoch gelungen,    Stoffe,   Legierungen oder Verbundkörper zu finden bzw. zu entwickeln    (z.B.      Niob,      Niob-Zinn,      Niob-Zirkonium   usw.), die auch bei technisch interessanten hohen magnetischen Feldstärken die Eigenschaft der    Supraleitung   beibehalten. 



  In    bekannter   Weise wurde deshalb auch bereits versucht, Transformatoren mit    supraleitenden      Wicklun-      gen   zu bauen und es gelang dabei, erhebliche Gewichtsersparnisse zu erzielen    (vgl.      Zeitschrift      < cElectri-      cal      World    Sept. 11, 196l).

   Bei derartigen    bekannten   Transformatoren lassen sich zwar    erhebliche      Gewichts-      ersparnisse   in Bezug auf die Wicklungen und - wegen der    kompendiöseren   Wicklungsanordnung - auch in Bezug auf den Eisenkern erzielen, für den    Magnetfluss   wird aber Eisen benutzt, so dass sich immer noch ein erheblicher Gewichtsaufwand bei grösseren    Leistungen   ergibt. 



  Um diesen Nachteil zu vermeiden, wird erfindungsgemäss vorgeschlagen, im Raum, in dem das Magnetfeld entsteht, kein    ferro-magnetisches      Material   zur Anwendung zu bringen. Dadurch    ergibt   sich auch der Vorteil des Wegfalles der Eisenverluste (Wirbelstrom-Hysterese). Die    Wicklungen   können dabei entweder freitragend    angeordnet   oder durch leichte Baustoffe abgestützt und am richtigen Platz    gehalten      sein.   



  Um Streuungsverluste    klein   zu halten, ist es    dabei   von    Vorteil,   die    Wicklungen   in Form von    Ringspulen   auszuführen, die entweder selbsttragend oder    unter      Zuhilfenahme      leichter,   nicht magnetischer    Materialien   mechanisch    getragen   werden. Es    kann   auch    vorteil.   haft    und      ökonomisch      sein,   in bestimmten Fällen    Auto-      Transformatoren   in dieser Weise    auszuführen.

    Superconducting transformer The invention relates to an electrical transformer with windings made from building materials which remain superconducting even at high magnetic field strengths.



  The disappearance of electrical resistance at the lowest temperatures (i.e. superconductivity) has been known for a long time. However, it could not be used for purposes of high-voltage engineering, for example in the construction of excitation coils for electrical transformers or machines, because the materials known until recently lose their superconductivity properties even in low magnetic fields.



     Recently, however, it has been possible to find or develop substances, alloys or composite bodies (e.g. niobium, niobium-tin, niobium-zirconium, etc.) which retain the property of superconductivity even with technically interesting high magnetic field strengths.



  Attempts have therefore already been made in a known manner to build transformers with superconducting windings, and it was possible to achieve considerable weight savings (cf. journal <cElectric World Sept. 11, 1961).

   With known transformers of this type, considerable weight savings can be achieved in relation to the windings and - because of the more compensatory winding arrangement - also in relation to the iron core, but iron is used for the magnetic flux, so that there is still considerable weight expenditure for greater powers results.



  In order to avoid this disadvantage, it is proposed according to the invention not to use any ferromagnetic material in the space in which the magnetic field is generated. This also has the advantage of eliminating iron losses (eddy current hysteresis). The windings can either be cantilevered or supported by lightweight building materials and held in place.



  In order to keep scatter losses small, it is advantageous to design the windings in the form of toroidal coils, which are either self-supporting or mechanically supported with the aid of light, non-magnetic materials. It can also be beneficial. be able and economical to implement auto-transformers in this way in certain cases.
