| Abstract(in English) | The main goal of this study is to clarify the arc-characteristics with different surface and shape conditions and to acquire basic insights for designing way for appropriate electrode structure for arc blowing by magnetic field. Silver-tin-dioxide material is chosen as typical contact material. To discuss the effects of step, decrement of area, and direction of Lorentz force, different contact shapes are prepared: "R-type" (normal shape), "Rpolish" at which R-type is polished by sandpaper, and "Rdeform" at which R-type is deformed so that contact has step asymmetrically. The concept of making step is to 1) suppress the movement of arc-column from edge to center of the contact, 2) make limitation of area at which arc-column can move. Breaking waveforms and aspects are measured. Arc-duration in the "Rdeform, but directions of step and Lorentz force are opposite" is the shortest in all conditions. |
