  • Patent number: 10332704
    Abstract: An arc protection system for an electrical enclosure having an electrical component positioned in an interior thereof. The system includes two busbars and at least one arc routing device positioned in the interior and an arc containment device defining a cavity and including an electrode assembly positioned within the cavity, wherein the electrode assembly is electrically coupled to the two busbars. The system also includes at least one arc routing device having a first end proximate the electrical component and a second end proximate the arc containment device. The at least one arc routing device is operative to i) attract arc plasma generated during an arc event at the electrical component, and ii) transport the arc plasma to the arc containment device, wherein the arc containment device is configured to transfer electrical energy of the arc plasma to an exterior of the electrical enclosure.

  • Patent number: 8993916
    Abstract: Equipment protection systems, arc containment devices, and methods of assembling arc containment devices are disclosed. In one example, an electrical isolation structure includes a conductor base, a cover coupled to the conductor base and defining an isolation chamber, a containment shield disposed on the conductor base within the isolation chamber, and a biasing assembly positioned between the cover and the containment shield. The containment shield defines a containment chamber configured to enclose the plurality of electrode assemblies. The containment shield is configured to at least partially contain the arc products within the containment chamber. The biasing assembly is configured to permit the containment shield to move away from the conductor base to thereby define a gap between the conductor base and the containment shield to enable at least some of the arc gases to vent from the containment chamber.

  • Patent number: 8981248
    Abstract: A circuit protection device is provided for use with a circuit that includes at least one pair of conductors. The protection device is configured to generate an arc. The protection device includes at least a pair of electrode assemblies electrically coupled to the at least one pair of conductors and a conductor base to support the pair of electrode assemblies. The protection device includes a cover coupled to the conductor base and defining at least one isolation chamber, wherein the electrode assemblies are disposed within the isolation chamber. The protection device includes a containment shield moveably coupled to the cover. The containment shield defines a containment chamber configured to contain charged particles produced by the arc. The containment shield is operative to move relative to the cover in response to a change in pressure produced by the arc within the containment chamber.

  • Patent number: 8922958
    Abstract: An electrical fault mitigation system includes a mitigation device including a containment chamber defining a cavity, a first electrode positioned within the cavity and coupled to a first conductor, and a second electrode positioned within the cavity and coupled to a second conductor. The mitigation device also includes a first voltage source, and a plasma gun positioned within the cavity and configured to emit ablative plasma using the first voltage source to discharge energy from an electrical fault. The system also includes a first voltage limiter device configured to limit a voltage of the first conductor from increasing above a predetermined threshold to prevent a second voltage source from generating a second electrical arc between the first electrode and the second electrode when the second voltage source applies a voltage across the first electrode and the second electrode.
