Rotorpol für einen Cryo-WechselstromgeneratorRotor pole for a cryogenic alternator
Bei einem Cryo-Wechselstromgenerator befindetsich die Rotorwicklung auf einer sehr niedrigen Temperatur, z.B. der des flüssigen Heliums, flüssigen Wasserstoffs oder flüssigen Stickstoffs.In a cryogenic alternator, the rotor winding is located at a very low temperature, e.g. that of liquid helium, liquid hydrogen or liquid Nitrogen.
Es ist bekannt, dass man die Rotoren von klassischen elektrischen Maschinen durch Flüssigkeitsumlauf in den Leitern selbst oder in Kühlkanälen kühlen kann, die zwischen den Lei tern angeordnet sind und in gutem thermischen Kontakt mit diesen stehen.It is known that the rotors of classic electrical machines can be made by circulating fluid in the conductors can cool itself or in cooling channels that are arranged between the Lei tern and in good thermal contact stand with these.
Diese bekannten Anordnungen eignen sich jedoch schlecht für Wicklungen, die durch fein unterteilte Leiter gebildet sind, wie sie bei Cryo-WechselStromgeneratoren vorkommen.However, these known arrangements are poorly suited for windings formed by finely divided conductors as they occur in alternating cryogenic current generators.
Die vorliegende Erfindung schlägt eine neue Ausführung für Rotorpole bei einem Gr go-Wechsel stromgenerator vor. Gemass der Erfindung ist die Wicklung eines Rotorpoles in dichten Kanälen angeordnet, die durch eine kontinuierliche Gesamt-The present invention proposes a new design for rotor poles in a Gr go alternating current generator.
