Abstract

Écran de protection contre le rayonnement thermique de l'enroulement d'excitation supraconducteur d'une génératrice. Le rotor qui contient l'enroulement d'excitation fonctionnant à ladite température à laquelle il est supraconducteur est entouré par un blindage électromagnétique de forme cylindrique. Un écran cylindrique de protection contre le rayonnement thermique est disposé entre le blindage et l'enroulement d'excitation de façon à intercepter la chaleur rayonnée par le blindage et à la rayonner à plus faible température vers l'enroulement d'excitation. Un dispositif de refroidissement rapide de l'écran le maintient à une température sensiblement uniforme sur toute sa longueur. Application aux génératrices supraconductrices dont l'induit est un stator fixe et l'inducteur, un rotor contenant un enroulement d'excitation rotatif maintenu à une très basse température à laquelle il est supraconducteur.
