要約(日本語): Running performance of small-current DC arc was experimentally investigated. For a large-gap or step, the minimum current of getting over the gap/step is saturated at about 40-50A, while the minimum current depends on the size of gap/step for a small gap/step with the region of about within 1mm. It indicates that the way of getting over a gap/step is different between the small-gap/step case and the large-gap/step case. The suggestion from this work is that a gap or step between an electrode chip and an arc runner should be completely eliminated in order to achieve better performance of DC small-current interruption.
