A remote-controlled dynamoelectric machine maintenance vehicle that can fit and travel within the air gap between a stator and rotor of a dynamoelectric machine. The maintenance vehicle has an effectuator that can remotely attach to an adjustable wedge within a coil slot of the stator and tighten the wedge in position and then move on to repeat the process until all the wedges on the stator are secured.

A system and method for testing an electrical generator of the type having a rotor (14) and a stator (12) includes or utilizes a movable carriage (22) having testing equipment which is sized to fit between the rotor (14) and stator (12) and is positionable over a selected stator (12) slot so as to be able to axially traverse the selected stator (12) slot, at least one sensor for sensing whether the movable carriage (22) is centered in an optimum position with respect to the selected stator (12) slot; and structure for centering the movable carriage (22) with respect to the optimum position if the sensor indicates the movable carriage (22) is not so centered, whereby accuracy of any testing by the testing equipment is optimized.

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.

摘要:
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).
摘要:
A device for removing a coating formed in a slot of a stator core. The device includes a carriage movably attached to a first guide rail assembly to enable movement of the carriage in a longitudinal direction. The device also includes a first drive screw wherein rotation of the first drive screw moves the first guide rail assembly in the longitudinal direction. In addition, the device includes a second guide rail assembly that is attached to the carriage wherein the second guide rail assembly enables movement of the carriage in a direction transverse to the longitudinal direction. Further, the device includes a second drive screw wherein rotation of the second drive screw moves the carriage in the transverse direction. The carriage includes a laser beam emitting head that moves within the slot in either or both the longitudinal or transverse directions wherein the laser beam emitting head emits a laser beam to remove the coating.
