In order to study the influences of contact opening speeds on arc extinction gap length characteristics, Ag contacts were operated to break DC inductive and resistive load currents from 0.1 A to 2.0 A at 14 V with contact opening speeds of 0.5mm/s, 1 mm/s, 2 mm/s, 5 mm/s and 10 mm/s in a switching mechanism employing a stepping motor, and arc voltage waveforms were observed at each opening of the contacts. From the results, the average arc durations were determined at each current level under the respective contact opening speeds, and the average arc extinction gap lengths were calculated by multiplying the average arc duration value and the contact opening speed value. It was found that with increasing the contact opening speeds, arc extinction gaps became larger in the inductive load conditions. In the resistive load conditions, the similar tendencies were also observed, although the gap lengths were on the order of several tens nm or less. |
