Abstract
Cooling system for a superconductive exciter winding in a turbogenerator rotor, the exciter winding having winding coils formed of a multiplicity of individual windings that are received in slots formed at the outer periphery of a solid support cylinder and retained therein by a bracing cylinder shrink-fitted on the support cylinder, includes coolant distribution channels disposed radially in teeth located between and defining the slot formed in the support cylinder and in filler members located between winding head coils, the coolant distribution channels surrounding the individual windings over the entire length thereof and being connected in peripheral direction on both sides thereof with coolant channels extending substantially parallel to one another in radial direction with the individual winding coils and surrounding the same at the bottom of the slots; and method of production.
