| Abstract: | Taking disposal on stator slot wedge shift in some pumped storage power plant as an example,reasons and dama-ges of stator slot wedge loose were analyzed. According to defects of primary slot wedge fastening way,new process of fix-ing middle part and end of slot wedge was proposed. This new process was able to greatly decrease possibility of slot wedge shift,ensure safe and stable operation of the unit and provide references for dealing with stator slot wedge loose in other power plants. |
