Patent ID: 7880350

Claim:
A hydrogen cooled generator having an axis and more than three phases, the generator comprising: a main casing section enclosing a stator with windings; a casing end section; at least one end winding disposed in the casing end section; a toroidal duct formed on at least one of the casing end section and the main casing section having a bottom wall and two side walls, wherein at least one of the bottom wall and the two side walls shares a wall of the casing end section so as to form a common wall; at least one bushing penetrating the common wall and inclined towards the axis of the generator so as to form an inclination relative to a radial direction of the generator, the at least one bushing having a first end connected to the at least one winding and a second end terminating in the toroidal duct; and a plurality of phase rings disposed in the toroidal duct, each of the plurality of phase rings having a first end connected to the second end of the at least one bushing, wherein the inclination of the at least one bushing forms a compact radial design so as to enable the toroidal duct to enclose the plurality of phase rings outside of the casing end section.
