Abstract
An arc transfer device for use in a switchgear includes at least one first electrical connector configured to connect the arc transfer device to a voltage supply within the switchgear, and a racking cassette. The racking cassette includes at least one second electrical connector that is configured to be electrically coupled to the at least one first electrical connector based on the racking position of the arc transfer device.
Claims20
An arc transfer device for use with electrical equipment, said arc transfer device comprising:
- at least one first electrical connector configured to receive power from the electrical equipment;
- and
- a racking cassette comprising at least one second electrical connector configured to electrically couple said at least one first electrical connector to the electrical equipment based on a racking position of said arc transfer device.
A circuit protection system for use with a circuit, said circuit protection system comprising:
- a controller configured to detect an arc flash event in the circuit;
- and
- an arc containment device operatively coupled to said controller and configured to generate an arc upon the detection of the arc flash event, said arc containment device comprising a racking cassette that facilitates racking said arc containment device in a plurality of positions, each of the plurality of positions related to an operating status of said arc containment device.
A switchgear stack comprising:
- at least one circuit;
- and
- a circuit protection system coupled to said at least one circuit, said circuit protection system comprising:
- a controller configured to detect an arc flash event in said at least one circuit;
- an arc containment device configured to initiate an arc in response to the detection of the arc flash event;
- and
- a racking cassette comprising:
- at least one racking member configured to couple to said arc containment device;
- and
- a shaft coupled to said at least one racking member and configured to drive said at least one racking member in one of a first direction and a second direction based on a racking position of said arc containment device.
