Abstract
Device for securing a superconductive exciter winding in a thermally insulating, thermally elastic and short-circuit proof manner within the rotor of a turbogenerator wherein the rotor has a body part thereof formed as a hollow cylinder, including a plurality of telescoping intermediate cylinders disposable within the hollow cylinder spaced from and coaxial to one another and to the hollow cylinder, the intermediate cylinders forming cold shields and damping means, the hollow cylinder being closed at both ends thereof, a support cylinder located within and spaced from the innermost of the telescoping intermediate cylinders and adapted to support a superconductive exciter winding on the inner side thereof, means for connecting the cylindrical rotor body part through the intermediate cylinders to the support cylinder force-lockingly yet resiliently in radial direction and free to expand in axial direction, the spaces between the cylinders being evacuated so as to insulate the cylinders thermally one from the other, and a plurality of cooling circuit means for maintaining the cylinders individually at varying temperature levels.
