Abstract :
Generator retaining ring is one of the maximum stress parts. The safety performance of hydrogen-cooled generator retaining ring directly affects the operation of generators and the influencing factors were studied in this paper. The mechanics of cracks on the retaining ring was analyzed. Using ANSYS finite element analysis software, the stress on the retaining ring of running generator is analyzed, and the main corrosion mediums which affected the safety performance of the retaining ring is studied. The results are concordance with practical situation.
