Abstract: In allusion to the self structural features of hydroelectric generating sets in Xiluodu power station, this paper used the specialized measuring tool to carry out refined calculation for the manipulation preloading, reasonably arranged the manipulation preloading along the distributed and configured ladder gaskets of magnet yoke axial and strictly controlled the temperature variation during the processes of heating and cooling. After the sets overspeed test and actual running, this process method guarantees the installation quality of this power station magnet yoke.
Key words: magnet yoke heat manipulation; preloading; technique method; special tools
