Decrease in the damage of powerful turbogenerator stator caused by vibration in the end zones (analysis, hypotheses, experiment)
The analysis of the turbogenerators’ TВВ-1000-2Y3 failure has shown that the most vulnerable link in the stator is such of their elements as tightening prisms, the teeth of the end packet core, lead-out and connecting buses of the stator winding. The basic reason for the destruction of the elements...

Electrical Engineering & Electromechanics| Резюме: | The analysis of the turbogenerators’ TВВ-1000-2Y3 failure has shown that the most vulnerable link in the stator is such of their elements as tightening prisms, the teeth of the end packet core, lead-out and connecting buses of the stator winding. The basic reason for the destruction of the elements mentioned is metal fatigue caused by excessive vibration under the influence of variable axial forces of electromagnetic origin. Preventing the destruction of the structural elements may be achieved by vibration monitoring and diagnostics. |
