A new method of lifetime estimation for High-Voltage insulating systems in rotating machines
Popis výsledku v původním jazyce
The stator wedge supporting material is used for diagnosing the state of the main insulation in rotating machines. The stator wedge is placed in a stator slot, and the material is aged using the same degradation conditions experienced by the bar windinginsulating system itself. The bar insulating system material and the stator wedge material were tested with differential scanning calorimetry (DSC). Additional laboratory thermal aging of the samples from both the bar winding insulating system and the supporting material was conducted to verify the suitability of the DSC method. Based on previous experience and on the thermal class of the insulating system, the aging temperature was set to 180 °C. Enthalpies were measured after 52, 70, 100 and 200 hoursof aging. The samples from three bars were analyzed. The area of the first thermal oxidative peak was evaluated. The experiment showed good agreement with the enthalpy results for the insulating system and the supporting material.
