| Abstract(in English) | In each contact material (Ag, Cu, Ni, Fe), the breaking arc occurring between electrical contact pair with low separating speed in DC42V/10.5A resistive circuit were observed with a high-speed camera (1000 frames/s). Arc voltage and current were also measured simultaneously. By analyzing cathode and anode bright spots in the photographs, the position of cathode and anode bright spots on contact surfaces were plotted on the screen. As a result, cathode and anode bright spots were carrying out the characteristic motion in each material. Moreover, by comparing those results with the contact surface photograph after all experiments, the damage process of the contact surface by the breaking arc was considered. |
