Superconducting DC circuit breaker using arcing induction

A superconducting arcing induction type DC circuit breaker comprising:

• a superconducting fault current limiter configured to perform a quenching operation at a speed of a half period or less in the event of line accident;
• and
• an arcing induction type DC circuit breaker including an induction member that has a through-hole, is continuously formed in a 360-degree direction, has a certain shape and thickness, and is made of a conductor material, and an induction needle that protrudes from an inner surface of the induction member toward a center of the induction member,
• wherein 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 a DC power or an AC power, and
• the induction member quenches the induced arc by the flow of the induced arc to ground through a ground line.
