Title:
METHOD OF ASSEMBLING A STATOR OF A VERTICAL HYDRO-GENERATOR
Document Type and Number:
WIPO Patent Application WO/1991/009446
Kind Code:
A1
Abstract:
A body (2) is made up of sectors (1) under factory conditions. Inside the body (2) are mounted axial wedges (6, 7), some (6) of them, adjacent to the end-faces of the sectors, being made dismountable. On the wedges (6, 7), standard segments (13) are placed in several layers within the limits of each sector (1) so that the segments (13) of each two adjacent layers would partially overlap each other. On the dismountable wedges (6) are put, at each second layer, shortened segments (16) adjoining each other at the joints of the sectors (1). Then the core (12) is press-fit, the winding is put into its slots (20), the stator is disassembled into sectors and is transported to its place of exploitation, where the sectors are reassembled. Then the dismountable wedges (6) are removed, the press-fit is weakened at the joints of the sectors, and every two adjacent shortened segments (16) are replaced by one additional standard segment (13a). The dismountable wedges (6) are then mounted and the core (12) is press-fit at the joints of the sectors.
