摘要:
A header (10) for use with an inner-cooled half coil (13) in a stator phase winding of an electrical generator. The half coil may include a stack of cooling tubes (16,18) with a first stack of conductive strands (20, 22, 24, 26) adjacent a first side of the stack of cooling tubes and a second stack of conductive strands (20, 22, 24, 26) adjacent a second side of the stack of cooling tubes. A header (10) is conductively bonded (92) by brazing to each strand of the first stack of conductive strands (20, 22, 24, 26) and to each strand of the second stack of conductive strands (20, 22, 24, 26) for consolidating the first and second stacks of conductive strands. A means (34, 36) for allowing a coolant to flow through the header (10) may be provided to allow coolant to flow through the stack of cooling tubes (16, 18). The means (34, 36) for allowing coolant to flow through the header (10) may include a plurality of apertures (34, 36) that are aligned with respective ones of the stack of cooling tubes (16, 18) for inspecting the cooling tubes through the apertures. Conductive connectors (54, 58) may be attached to and removed from the header without affecting the consolidation of the conductive strands.

In one embodiment the present invention provides for a method for checking the alignment of a stator core that comprises placing a laser source 14 and a target 18 a given distance apart on a stator core 10 and activating the laser such that the laser strikes the target. Then measuring on the target where the laser strikes, and interpreting the measurement to determine any misalignment of the stator core in the given distance.

The present invention provides an apparatus for the horizontal stacking of laminations 10 and donuts to form a stator core. A stator generator frame 2 has multiple keybars 6 that run the axial length of the frame. The laminations 10 have grooves 12 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 6, these extensions 7 may be used as rails on which the laminations may be horizontally inserted into the stator frame.
