| Abstract(in English) | For the basic research of the evaluations of material properties, which are practically used for current switches with breaking arc dischrge, the discharge mark whose area is surface damage of contact by breaking arc discharge, are observed using SEM, and its area in the image is estimated. In this report, five kinds of contact materials, Ag and Ag compounds with Cd and Sn are used at the conditions of 40V of open voltage, 4A of close current and 10mm/s of opening velocity. Estimation of the electrode damage are performed opening motion number of one, ten, fifty and one hundred times. The surface of those contact materials both anode side and cathode side observed by SEM, and each discharge mark areas were measured. In result, characteristic of each contact material, and characteristic of anode side and cathode side were observed clearly. |
