Abstract
During the long-term operation,the main insulation material of generator stator winding is affected by many fields of heat,electricity,magnetism,force and complex environmental factors,so it is easy to appear local aging,thus reducing the insulation performance.it seriously endangers the safety of the equipment and the stability and reliability of the system.This paper takes the stator winding coil and its insulation layer in a large hydropower station as the research object,and adopts special material analysis technology according to the characteristics of composite material and interface.The changes of the structure,morphology,composition and micro-defects of the insulation material near the copper wire after the motor has been in service for a period of time are studied systematically.The results show that after one year of use,the local micro-cracks appear in the insulating layer coating material near the side of the copper wire,and the corresponding material properties change,and show the difference with the position distribution.The research results provide empirical support for continuously tracking the evolution of material properties in motor service reliability.关键词
