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.

A current interrupter, the current interrupter comprising:
- a fixed terminal end;
- a moveable terminal end;
- and
- at least two arcing contacts, wherein the two arcing contacts include at least an anode contact and at least a cathode contact and wherein the at least two arcing contacts are fabricated with a first conducting material having a first vaporizing temperature and a second conducting material having a second vaporizing temperature, wherein the first vaporizing temperature is lower than the second vaporizing temperature.
A system for isolating a fault in a direct current (DC) grid using thermionic arc extinction, the system comprising:
- a direct current (DC) grid, said DC grid comprising:
- a transmission line;
- and
- at least a current interrupter disposed on the transmission line, wherein the at least one of the current interrupters comprises:
- a fixed terminal end;
- a moveable terminal end;
- and
- at least two arcing contacts, wherein the two arcing contacts include at least an anode contact and at least a cathode contact and wherein the at least two arcing contacts are fabricated with a first conducting material having a first vaporizing temperature and a second conducting material having a second vaporizing temperature, wherein the first vaporizing temperature is lower than the second vaporizing temperature.
