In a DC inductive load circuit (L=20mH) with a power supply voltage of DC14V, break operations of a load current in the range from about 1 to 9 A were conducted with a AgSnO2 contact pair at a contact opening speed in the range from 0.5 mm/s to 200 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 durations are said to become shorter with a faster contact opening speed, such tendencies were clearly recognized only with larger load current levels. With faster contact opening speed levels, the tendencies became less significant. Moreover, increases in contact opening speeds were found to provide significant increases on metallic phase durations, leading to their reduction. |
