Abstract :
In order to make Three Gorgespsila evaporative cooling hydrogenerators have the best thermal performance, optimal design for the evaporative cooling system of stator bar has been made, and the thermal characteristic of the stator was analyzed by 3D FEM coupled analysis tool in this paper. The results provide the design basis for the industrial unit and show the evaporative cooling generator has lower stator temperature level and even temperature distribution.
