Title (EN) ROTOR WINDING HEAD BLOCKING FOR IMPROVED COOLING OF TANGENTIAL CONDUCTORS
(FR) ÉLÉMENT DE FERMETURE POUR UNE TÊTE DE BOBINE D'UN ENROULEMENT ROTORIQUE PERMETTANT UN MEILLEUR REFROIDISSEMENT DES CONDUCTEURS TANGENTIELS
(DE) ROTORWICKELKOPFVERBLOCKUNG ZUR VERBESSERTEN KÜHLUNG DER TANGENTIALLEITER
Abstract:
(EN) The invention relates to a blocking element for the rotor head winding of a turbogenerator, said element comprising one or more openings which are oriented tangentially to the shaft. A gas flow which passes through the blocking element is formed between the transverse conductors of the rotor winding head. The cooling of the rotor winding head is improved in an advantageous manner.
(FR) L’invention concerne un élément de fermeture pour l’enroulement rotorique d'un turboalternateur, ledit élément de fermeture comportant une ou plusieurs ouvertures orientées tangentiellement à l'arbre. Un écoulement gazeux traversant l'élément de fermeture se forme entre les conducteurs transversaux de la tête de bobine d’un enroulement rotorique. De manière avantageuse, l’invention permet d'améliorer le refroidissement d'une tête de bobine d’un enroulement rotorique.
(DE) Das erfindungsgemäße Verblockungselement für die Rotorkopfwicklung eines Turbogenerators weist eine oder mehrere Öffnungen, die tangential zur Welle orientiert sind, auf. Zwischen den Querleitern des Rotorwickelkopfes bildet sich eine Gasströmung aus, die das Verblockungselement passiert. In vorteilhafter Weise ist eine Verbesserung der Rotorwickelkopfkühlung gegeben.
