MULTI PHASE GENERATOR WITH FREQUENCY ADAPTATION UNIT
First Claim
1. A hydrogen cooled generator having an axis and a plurality of phases, the plurality of phases including 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, the at least one bushing having a first end connected to the at least one end winding and a second end terminating in the toroidal duct;
a frequency adaptation unit disposed in the toroidal duct, including at least one rectifier portion having an input end connected to the second end of a respective one of the at least one bushing; and
a positive and a negative polarity collection ring each connected to an output end of a respective one of the at least one rectifier portion, wherein the at least one rectifier portion forms a rectifying bridge between the plurality of phases and the positive and the negative polarity collection ring.
