Abstract :
Recently, independent research was carried on evaluation of domestic VPI insulating materials and consequently simulated stator. In this paper, lots of experiments were executed to verify and evaluate the VPI insulation materials and insulation system domestic. Raw materials were measured regarding thermal, chemical, electrical and dielectric properties based on panel samples. Single simulation bars produced by VPI technology were tested by means of dissipation factor, dielectric breakdown and voltage endurance. The characteristics of epoxide/anhydride impregnating resins, impregnated mica tapes and panels was compared between domestic and oversea products. This research is a systematic work regarding both of VPI insulating materials and technology, which has far-reaching significance to the future study and application.
