Superconducting DC circuit breaker using arcing induction
A superconducting arcing induction type DC circuit breaker includes a superconducting fault current limiter and an arcing induction type DC circuit breaker connected in series to each other. The arcing induction type DC circuit breaker includes an induction member that has a through-hole, is continuously formed in a 360-degree direction, and has a certain shape and thickness, and an induction needle that protrudes from an inner surface of the induction member toward a center of the induction member. A contact point where an anode and a cathode, which are mechanical contacts, approach from opposite directions and come into contact with each other is formed in the through-hole of the induction member, and the anode and the cathode are separated in a direction far away from each other. The induction needle induces arc generated upon contact opening when the anode and the cathode are separated from each other in the event of system accident of DC power or AC power, and the induction member quenches the induced arc by the flow of the induced arc to ground through a ground line.
