This paper compared and analyzed the arc-induction efficiency of a superconducting arc-induction type DC circuit breaker. The superconducting arc-induction type DC circuit breaker comprises superconducting magnets, a mechanical cutoff contact, and an induction needle. In addition, by inducing the arc generated from the mechanical contact using the induction needle connected in series with the ground wire, the high efficiency of the arc extinguishing operation is performed. However, to perform a reliable arc-induction operation, verification of the use of an appropriate induction needle is required. Therefore, we compared and analyzed the arc-induction characteristics depending on the arc length between the mechanical contacts and the presence or absence of superconducting magnets. As a result, it was confirmed that the blocking operation time was shortened by about 21 times depending on the presence or absence of the superconducting magnet, and the result that the arc length affected the arc-induction rate was confirmed.
