摘要
SF6/N-2 mixture gas is an environmentally friendly sealing gas for power equipment. The multiple arc erosion performance of Ag/Ti3SiC2 composite was investigated in SF6/N-2. During the multiple arc erosion process, the relative breakdown strength increased with the operation number, and the breakdown current and arc duration were randomly distributed in a certain range. Ag spheres were observed on the material surface in the arc erosion region. For the Ti3SiC2 reinforcing phase, a silicon de-intercalation phenomenon was observed in the eroded region. Additionally, instantaneous photographs of the arc erosion process were recorded.
