| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | AgSnO2 contacts were operated to break an inductive DC load circuit of 14V-7A, 14V-12A, 20V-7A, or 20V-17A with an applied external magnetic field of about B=120mT at contact opening speeds in the range of 1mm/s to 200mm/s. During the break operations, arc voltage and current waveforms were measured, and in addition, arc movements were observed and recorded by means of a high-speed camera. In the cases with slower contact opening speeds and smaller load current levels, the measured arc voltage waveforms indicated shortening in the arc durations, while apparent magnetic blowing phenomena were not observed. In such cases, arc movement observations revealed that break arcs were likely to be moved in the direction opposite to the Lorentz force direction. Such phenomena were repeatedly observed, although any physical mechanism which can explain the phenomena are still unknown. | |
