Patent number: 6876222Abstract: An automated tool for performing an EL CID inspection of the step iron region of a generator stator that can be employed with the rotor in place. The tool has a track that is axially cantilevered at one end and supported magnetically within a stator slot adjacent the region to be monitored. The track has a smoothly rounded contour that approximately conforms to the profile of the stator step region. A carriage carrying a pickup coil is slideably mounted on the track and is driven back and forth along the track over the area to be inspected by a remotely-operated drive system. A video camera is mounted on the track and provides a remote visual indication of the location of the carriage relative to the stator.Type: GrantFiled: November 12, 2002Date of Patent: April 5, 2005Assignee: Siemens Westinghouse Power CorporationInventors: Mark W.

Patent number: 6619109Abstract: An inspection apparatus (40) for in-situ leak testing of the bell seal (30) of a steam turbine (10). The apparatus includes a pair of inflatable bladders (48,52) for defining a sealed volume having the bell seal (30) as its only leakage path. The mass flow rate of pressurized air (70) at various pressures through the bell seal (30) is compared to the known flow rates through a similarly designed bell seal having various degrees of degradation. A camera (60) rotated by motor (62) between the bladders (48,52) provides an indication of the proper positioning of the inspection apparatus (40) and facilitates a visual inspection of the bell seal (30) and retaining nut (42). The inspection apparatus (40) may be inserted into an inlet to the turbine through a disassembled flow control valve without the need for any disassembly of the turbine.Type: GrantFiled: September 25, 2000Date of Patent: September 16, 2003Assignee: Siemens Westinghouse Power CorporationInventors: George F.

Patent number: 6487922Abstract: An inspection apparatus (40) for remote inspection of the trepan radius area (34) of the inlet sleeve (24) of a steam turbine (10). The apparatus (40) provides a sealed volume (50) between a pair of inflatable bladders (46,48) for the introduction of a liquid couplant for the immersion of ultrasonic transducers (42,44). A laser line generator (62) generates a beam of light visible through camera (60) which impinges upon the inlet bell seal (30) when the apparatus (40) is in a proper inspection position within the inlet sleeve (24). Guide vanes (56) provide centering and generate an insertion force during air assisted insertion of apparatus (40). Transducers (42,44) are indexed axially and circumfretially by the independent rotation of axial drive gear (72) and longitudinal drive gear (70) engaged with a pattern of gear teeth (69) formed as a combination of circumferential spur gear teeth and axial rack gear teeth cut into a single surface of a spline shaft (68).Type: GrantFiled: September 25, 2000Date of Patent: December 3, 2002Assignee: Siemens Westinghouse Power CorporationInventors: James A.

Patent number: 5760371Abstract: 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.Type: GrantFiled: December 8, 1995Date of Patent: June 2, 1998Assignee: Westinghouse Electric CorporationInventors: George F. Dailey, Gary W. Swartzbeck, Greyson L. Mellon, Michael T. O'Leary

Patent number: 5689734Abstract: Camera system for viewing an object located in a region of contamination (e.g., oil, water, particulate matter, or the like). The system is capable of being internally pressurized above ambient pressure, so that the contamination is prevented from entering the camera system to foul the camera. The system includes a housing having an interior and a view port. An electronic sensor is disposed in the housing opposite the port for sensing the object and for generating an electrical output signal that travels along a conductor connected to the sensor. A processor is connected to the conductor for amplifying the output signal. The amplified signal is received by a display monitor which displays an image of the object. The system further includes a quick-disconnect connector which interconnects the housing to a source of pressurized fluid used to pressurize the housing above ambient pressure.Type: GrantFiled: August 26, 1996Date of Patent: November 18, 1997Assignee: Westinghouse Electric CorporationInventors: James A.
