초록

For the development of HVDC cable connector, Nano SiC was corroded in H2O2 to form Si-OH . On the basis of SiR, Nano SiC was chemically treated with vinylsilazane. Samples were prepared by homogeneously dispersing the modified Nano SiC in silicon according to the doping level content (0, 1, 3, 5, 7, 9 wt%). It is to develop a controllable material with nonlinear conductivity that can homogenize electrical stress in HVDC cable connectors. In addition, in order to develop a material with strong partial discharge resistance and thermal conductivity, high voltage stress was applied for 500 hours in a 5kV/720Hz environment. As a result, the erosion depth of the surface was measured. Heat conduction was measured and evaluated to investigate the effect of high voltage stress on heat conduction.
