Method and apparatus for generator stator core separation

摘要

An intercoupled stator core is separated from a non-vertically oriented (including horizontal) generator frame by decoupling the stator core and frame coupling members and interposing a slidable member between them. Thereafter they are separated relative to each other on the sliding member. The sliding or slidable member may comprise a rail, or alternatively a roller adapted for rolling contact with one of the opposed stator core or generator structures and an engagement surface in contact with the other structure. A system for separating the stator core from a non-vertically oriented generator frame includes first and second raising end plates adapted coupled to axial ends of the stator core. The end plates project outwardly from the generator frame ends, for coupling to a raise mechanism. After the raise mechanism raises the stator core the slidable member is interposed between the stator core and generator frame.

1. A method for separating an intercoupled assembled stator core from a non-vertically oriented generator frame, comprising:
providing a generator, which includes an assembled stator core having a lamina stack of individual laminations that are retained in compressed axial and radial alignment by an opposed pair of stator core end plates and axially oriented bolts that are coupled to the respective end plates; a generator frame that circumscribes the assembled stator core; and coupling members for coupling the assembled stator core and frame; decoupling respective coupled stator core and frame coupling members; interposing at least one sliding member between the stator core and frame; and sliding the respective assembled stator core and frame relative to each other on the at least one sliding member, without removing individual laminations from the assembled stator core lamina stack, so that they are separated from their initially coupled relative positions.
