| Abstract(in English) | An evaluation system enabling observation and evaluation of changes on contact surface conditions (growth of a crater and/or a pip) during switching operations has been being constructed. Up to now, evaluation of a movable cathode surface profile by way of an optical cross-section method, as well as observation of the counterpart stationary anode surface by means of a CCD camera, has been realized. For the cathode surfaces, temporal changes in cross-sectional profiles along a particular line over a crater formed on the cathode surface were observed. In this paper, more visual observation of temporal changes in the cathode surface conditions (a crater growth process) during switching operations were tried by drawing three-dimensional images of the movable cathode samples based on data obtained with the optical cross-section method. More specifically, Ag contact pairs and AgSnO_2 contact pairs were operated to break a DC14V-2A or 3A load current in a DC inductive circuit, and changes in the contact surfaces during the switching operations were observed and evaluated. |
