Abstract

Dispositif de raccordement de transmetteur d'hélium pour machine électrique à enroulement d'excitation supraconducteur. Un élément central disposé dans l'extrémité de l'arbre de la machine électrique peut contenir des soupapes qui obturent l'intétieur du rotor lors d'une chute de la pression de l'hélium de refroidissement et/ou lors d'une réduction de la vitesse de rotation du rotor. Le dispositif comprend avantageusement au moins un élément élastique pour assurer un contact étanche à la surface de séparation du dispositif de raccordement. Applications montage et démontage rapides et simples du transmetteur d'hélium.
