| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In a DC inductive load circuit (L=20mH) and a DC resistive load circuit with a power supply voltage of DC14V, break operations of a load current in the range from about 0.8 to 4 A were conducted with a Ag contact pair and a AgSnO2 contact pair at a contact opening speed in the range from 0.5 mm/s to 20 mm/s. During the operations, break arc durations were measured and the average break arc duration was calculated in each operating condition. Although break arc duration is said to become shorter with a faster contact opening speed, no influences of contact opening speeds on average break arc durations were found for the Ag contact pair in the inductive circuit. For the break operations by the AgSnO2 contact pair in the inductive circuit, the average break arc duration at larger load current levels became shorter with the contact opening speed of 5 mm/s or less. However, no significant influences were recognizable with the faster speed range. In the resistive load circuit, more complicated influences of the contact opening speed were observed, in which the average break arc duration showed the local minimum at a certain opening speed value. When an average gap length at which a break arc extinguished was calculated by multiplying the average break arc duration value and the contact opening speed value, the resultant values became longer in general with increases in the contact opening speeds. | |
