Abstract(in English) | Material transfer and erosion shapes, formed by arc discharges on the surfaces of Ag contacts that interrupted an inductive load current of DC 1 to 3 A with DC 14 V, were numerically evaluated by means of a laser microscope. With respect to craters formed on the cathode surfaces, diameters thereof were likely to be larger with larger load current values, while the depths thereof did not show significant differences. The characteristics of volume values of the transfer and erosion shapes on the contact surfaces after the operation tests showed the tendencies similar to those of the mass changes of contacts before and after the tests, except for the anodes operated with 3 A. On the other hand, upon comparison of the mass change values calculated from the measured volumetric values to the measured mass change values, relatively proportional relationship was recognized. However, differences in their order of about one digit were found, and the reasons therefore are unknown at this time. |
