查询词典 DMA

The four sets of stator bars including those retired from three large generators and the standby bar subjected to Dynamic Mechanical Analysis, Scanning Electron Microscopic and optical microscope observation. It was revealed from DMA that the peak value tan d m of mechanical loss thermogram tan d ~ T shift toward a higher temperature and a lower amplitude, indicating that the amount of movement monomers diminished greatly in the insulation aging process, the tan d 195, increased very slightly with the service time of insulation, showing the degrading of bonding properties at interface, and the presence of more defects in insulation. The observation of SEM and optical microscope showed that more and more voids appears in insulation, and delamination was formed due to development of voids in aging process.
