Abstract: A device for thermionic arc extinction via anode ion depletion. The device includes a body including an inner compartment. The inner compartment includes at least an arc shield housing at least two arcing contacts, wherein the two arcing contacts are zinc-plated. The at least two zinc-plated arcing contacts further comprise a thickness and contact area customized based on a desired corrosion time of the zinc, wherein the corrosion time corresponds to extinction of the arc. A sensor is associated with the device. The sensor is configured to operate the movement of the at least two arcing contacts.

Abstract: A system for isolating a fault in a direct current (DC) grid using thermionic arc extinction. The system includes a DC grid that includes a transmission line. The DC grid also includes a plurality of current interrupters disposed on the transmission line. Each of the plurality of current interrupters on the transmission line are electrically coupled to one another in series. At least one of the current interrupters includes a fixed terminal end and a moveable terminal end. Further, at least one of the current interrupters has an arc shield housing at least two arcing contacts. At least one of the arcing contacts comprises a first conducting material that has a first vaporizing point.
