Abstract:Electrode material seriously influences the characteristics of vacuum arc and further affects the performance of switches. In this paper, thermal processes of six kinds of metal anodes (including pure metal and alloy anodes) are simulated and researched. Two kinds of temperature calculation methods are used. Simulation results show that W and Mo anodes have the higher temperature than Cu, Cr, CuCr25 and CuCr50 anodes. Pure Cr anode has the biggest melting width, and highest saturated vapor pressure. Cu anode h… Show more
