Discharge Behavior Of The Nanostructured Insulation Material For High Torque Density Electrical Propulsion
2019 IEEE CONFERENCE ON ELECTRICAL INSULATION AND DIELECTRIC PHENOMENA (CEIDP)(2019)
摘要
The All Electric Ship requires significant higher torque/power density and payload efficiency of marine propulsion and power generation. The novel nanostructured insulation material based on 2D platelet clay has been successfully developed. Our studies show that the novel nanostructured insulation will lead to 2X combined improvement in the both electrical, thermal performance over the state-of-the-art micaceous. Particularly, the novel material demonstrated the outstanding discharge resistance which is comparable to mica. In this paper, the behavior of the discharge during the voltage endurance testing has been extensively investigated to elucidate the mechanism behind the superior discharge resistance. The results revealed that the novel nanostructured insulation material is able to autonomously suppress the discharge and hence slow down the degradation. This phenomenon is not observed in the neat epoxy or alumina nanocomposite.
