Abstract: A baffle system for routing cooling fluids through a dynamoelectric machine. The baffle system may include a locking cam mechanism for releaseably attaching a baffle to a stator assembly to substantially eliminate an annular air gap between a rotor assembly and a stator assembly. The baffle system may include a locking strip attached to a stator slot wedge to seal the locking cam mechanism and baffle to the stator assembly. In other embodiments, the baffle system may include a friction pad for sealing the locking cam mechanism and baffle to the stator assembly. The baffle system may also include a locking tool for simultaneously, or individually, moving the locking cam mechanism from an unlocked position to a locked position, or vice versa.

Abstract: A ground detection apparatus for use in a power generating system including an excitation circuit and a driven rotatable shaft. A ground detector ring is disposed on the rotatable shaft of the power generating system. A ground detection transmitter is mounted on the ground detector ring and in electrical communication with the excitation circuit of the power generating system. The ground detection transmitter is utilized to detect ground faults in the excitation circuit of the power generating system and to send a signal associated with ground faults detected by the ground detection transmitter. A ground detection receiver is associated with a stationary portion of the power generation system and is in communication with the ground detection transmitter for receiving the signal associated with ground faults detected and sent by the ground detection transmitter.

Abstract: A gas-cooled turbine generator includes a rotor having baffles arranged in rings and defining a plurality of gas cooling zones. A stator core has stator slots in a bore in which the rotor is received. A plurality of air gap baffle assemblies are arranged in segmented baffle rings in the stator slots and cooperate with the zone rings on the rotor. Each of the air gap baffle assemblies includes at least one baffle segment and an individual locking cam cooperating with a respective wedge of the baffle segment to lock the baffle segment relative to a stator slot at which the baffle segment is positioned such that prior baffle “trains” are no longer required.
