An inspection system inspects the interior of the stator of an electric generator for the existence of several problems. The inspection apparatus is mounted on a carriage that travels along the slots defined by the stator. An indexer is mounted to the rotor of the generator and can travel around the circumference of the rotor to deliver the carriage to the desired slot. An indexer plate is mounted to the indexer and can be registered with the desired slot to insure that the carriage can enter the slot from the indexer. An associated motor controller disables the motor if an electrical fault is disclosed.

An inspection apparatus ( ) for remote inspection of the trepan radius area ( ) of the inlet sleeve ( ) of a steam turbine ( ). The apparatus ( ) provides a sealed volume ( ) between a pair of inflatable bladders ( ) for the introduction of a liquid couplant for the immersion of ultrasonic transducers ( ). A laser line generator ( ) generates a beam of light visible through camera ( ) which impinges upon the inlet bell seal ( ) when the apparatus ( ) is in a proper inspection position within the inlet sleeve ( ). Guide vanes ( ) provide centering and generate an insertion force during air assisted insertion of apparatus ( ). Transducers ( ) are indexed axially and circumfretially by the independent rotation of axial drive gear ( ) and longitudinal drive gear ( ) engaged with a pattern of gear teeth ( ) formed as a combination of circumferential spur gear teeth and axial rack gear teeth cut into a single surface of a spline shaft ( ).

A dynamoelectric machine's segmented baffle assembly comprises a baffle ring which is bolted to a back-up plate disposed in the stator core. The annular-shaped baffle ring is formed from a plurality of arcual segments, each segment secured by at least one of said bolts. For low flow rates of coolant gas, the air gap can be further reduced by means of a teflon insert located on the inner circumferential surface of the baffle ring. For expeditious access to the rotor assembly, only one of said segments need be.

A flux probe () for measuring the rotor flux of an electric generator (). The probe () is affixed to a probe carrier () and held within a stator coil slot () by affixing the carrier () to two opposing grooves () formed in sidewalls () of the slot (). One or more stator coils () are also disposed in the slot () and retained therein by a wedge () and corresponding spring () that applies an radially outwardly directed force to the coils (). In one embodiment the probe carrier () is affixed to a radially inwardly directed face () of the wedge ().

A large turbine generator is provided with a stator end winding assembly that includes a large conical member outside the coils which is joined by banding with adjusting rings radially inside the coils, with an adjusting means for each banding location that includes a wedge extending through an aperture in a portion of the adjusting ring that extends away from the coil and having a fastener that is joined to the wedge so that upon the tightening of the fastener, the wedge will be forced in the axial direction bearing against the banding and hence tightening it; and in addition, the conical member is provided with projections serving as torque splines that fit within apertures of the core so as to prevent its rotational movement in operation.

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.

The present invention provides for an insulating boot for ends of through-bolts in electric generators that comprises a shaped insulating boot. The boot has an inner surface and an outer surface and an opening, where the inner surface is substantially free of protrusions. The inner surface of the shaped boot is within 0. 01 to 0. 5 inches (0. 025–1. 3 cm) larger than the shape of the end of a through-bolt to which the shaped boot will be applied. The shaped insulating boot has a breakdown voltage of at least 10 kV, and more particularly at least 30 kV, and the shaped boot is placed over the end of a through-bolt of an electric generator.

The present invention provides an apparatus for the horizontal stacking of laminations and donuts to form a stator core. A stator generator frame has multiple keybars that run the axial length of the frame. The laminations have grooves there-in that engage the keybars to provide a secure fit of the laminations to the generator frame. By extending two or more of the keybars , these extensions may be used as rails on which the laminations may be horizontally inserted into the stator frame.

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.
