Abstract
One 330 MW steam turbine generator of a power plant was damaged in Inner Mongolia, not only caused generator slip ring and carbon brush burning, but also the generator shaft damaged. Analysis the cause of the failure was due to the insulating sleeve quality defects, tripping out of glass cloth by high speed rotating rotor fan was broken and went into the slip ring and carbon brush, eventually led to the fault. Through the scene processing, repaired the generator shaft, collector ring and carbon brush. At present, the generator is running in good condition. Through the fault handling, it is suggested that there are power plants of the same kind of generator, reinforce the generator slip ring insulation sleeve.关键词
