| Abstract: | Based on the experiments about switching performances of the AgSnO 2 contact material with different doping agents (WO 3, Bi 2O 3, In 2O 3) and the observations of the contact surface microstructure, the effects of additives on the erosion behavior of AgSnO 2 were studied from the view points of dopants as a wetting aid, the thermal stability of the additive and the effect of the dopant on the viscosity of liquid silver metal. The modification characteristics of additives on the AgSnO 2 contact arc erosion behavior were presented. |
