Abstract
A blocking element for a rotor head winding of a turbogenerator has a form which is adapted to the contour of the adjacent conductor of the rotor head winding. A depression extending in the axial direction is made in the side of the blocking element facing the conductor, which depression forms a serpentine channel for a cooling fluid from an inlet port on the small radius to a discharge port on the highest radius, with the discharge port communicating with a ventilation bore of the rotor cap enclosing the rotor winding head. An improved cooling effect with a reduced flow of cooling fluid and an increase in the efficiency of the turbogenerator as a whole results.
