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.Protective screen against thermal radiation of the superconducting excitation winding of a generator. The rotor which contains the excitation winding operating at said temperature at which it is superconducting is surrounded by an electromagnetic shield of cylindrical shape. A cylindrical shield against thermal radiation is arranged between the shielding and the excitation winding so as to intercept the heat radiated by the shielding and radiate it at a lower temperature to the excitation winding. A rapid cooling device for the screen keeps it at a substantially uniform temperature along its entire length. Application to superconducting generators of which the armature is a fixed stator and the inductor a rotor containing a rotating excitation winding maintained at a very low temperature at which it is superconducting.
