George F. Dailey - Pittsburgh PA, US
Michael O'Leary - Apollo PA, US

Assignee:

Siemens Power Generation, Inc. - Orlando FL

International Classification:

G01R 31/02

US Classification:

Abstract:

A mount is for installing a probe, such as for example, a search coil, in a variety of locations and orientations within an electrical generator, without requiring the rotor of the generator to be removed. The mount includes a block having a longitudinal hole and a plurality of transverse slots intersecting the hole. A plurality of wedges are disposed within the slots. A wedge pin inserted into the longitudinal hole engages the wedges forcing the wedges outward in order to secure the mount and search coil thereon in the desired position within the generator, such as for example, in the air gap between the rotor and stator. A fastening mechanism further secures the mount in place.

US Classification:

269269, 254 89 R

Abstract:

A repair fixture for supporting large cylindrical objects such as a generator rotor, to facilitate field maintenance operations. The fixture has two spaced Vee-blocks that are supported by and moved within vertical channels formed within peripheral stanchions. Clevises are rotatably connected at one end to both lateral sides of the Vee-block and at the other end to a hydraulic piston that is employed to raise and lower the Vee-blocks in unison to accommodate various maintenance requirements.

International Classification:

B23K 100

US Classification:

219129

Abstract:

A process is disclosed for repairing leaks in turbine generators that have water cooled stator coils with hollow conductor strands. Such generators have a tendency to leak where the stator coil joins a header. Once a leak is detected the repair is accomplished by following the steps off the invention. First, the header is cut into an outboard section, and into an inboard section that remains attached to the conductor strands. Second, the exposed lead ends of the conductor strands and the attached inboard section are cleaned to remove oxidation. Third, a water-tight braze seal is applied over the lead ends of the conductor strands. And finally, the stator coil and the inboard section are joined to a new outboard section.

International Classification:

US Classification:

29890052

Abstract:

A method for installing a header cap on a water header both positioned on a stator coil. The method includes the steps of creating a generally smooth surface on the water header for providing a mating surface on the water header. A seal is interposed between the mating surface of the water header and the header cap for providing a material used to provide a sealed boundary between the cap and mating surface. The header cap and the mating surface of the water header are placed in abutting relationship with the seal for forming a layered, contiguous connection. A pressure device is attached in operative association with the header cap for operatively applying a pressure to the header cap. A spring which is received by the pressure device is compressed for applying a constant and unidirectional pressure to the pressure device which, in turn, transmits the constant and unidirectional pressure to the header cap. The connection is finally heated for brazing the header cap and water header together and for forming a seal.
