| Abstract(in English) | In each contact material (Ag, Au, and Ni), the breaking arcs occurring between an electrical contact pair in a resistive circuit of DC42 V/10.0 A were observed with a high-speed video camera (1000 frames/s), and behaviors of cathode bright spots were analyzed. Moreover, the erosion of the contact surfaces of each material were observed by scanning electron microscope (SEM), and qualitative analysis of the arc erosion was also done by energy dispersive spectroscopy (EDS). As results, the behavior of the arc spot moved widely in the metallic contact that does not adhere the oxygen molecule easily. In the metallic contact that adheres the oxygen molecule easily, on the other hand, the behavior of the arc spot is stationary. |
