Abstract
An arc chute assembly is for an electrical switching apparatus including a housing and an arc hood coupled thereto, the arc hood being structured to exhaust arc gases from the housing. The arc chute assembly includes a vent portion structured to exhaust arc gases from the housing into the arc hood and a frame portion adjacent the vent portion. The frame portion being structured to be movably coupled to the housing. The arc chute assembly being structured to be movable from a first position to a different second position relative to the housing responsive to the exhaust arc gases.
Claims16
An arc chute assembly for an electrical switching apparatus including housing and an arc hood coupled thereto, said arc hood being structured to exhaust arc gases from said housing, said arc chute assembly comprising:
- a vent portion structured to exhaust arc gases from said housing into said arc hood;
- and
- a frame portion adjacent said vent portion, said frame portion structured to be movably coupled to said housing,
- wherein said arc chute assembly is structured to be movable from a first position to a different second position relative to said housing responsive to said exhaust arc gases.
An arc hood assembly for an electrical switching apparatus, said electrical switching apparatus including a housing having a number of arc chutes having a vent portion structured to exhaust arc gases from said housing and a frame portion adjacent said vent portion, said number of arc chutes being movable from a first position to a different second position during venting of said arc gases, said arc hood assembly comprising:
- a hood member fixedly coupled to said housing at or near said number of arc chutes, said hood member being structured to receive and exhaust said arc gases vented from said housing;
- and
- a number of transverse members structured to contact said number of arc chutes when said number of arc chutes are in said different second position.
An electrical switching apparatus comprising:
- a housing;
- separable contacts enclosed by said housing;
- an operating mechanism structured to open and close said separable contacts, which are structured to create an arc that generates arc gases when said separable contacts open;
- a number of arc chute assemblies disposed with respect to said housing, each of said number of arc chute assemblies comprising:
- a frame portion movably coupled to said housing;
- and
- a vent portion adjacent said frame portion, said vent portion being structured to exhaust the arc gases from said housing;
- and
- an arc hood coupled to said housing at or near the vent portion of each of said number of arc chute assemblies, said arc hood being structured to receive the arc gases exhausted from said vent portion of each of said number of arc chute assemblies and exhaust said arc gases from said electrical switching apparatus,
- wherein each of said number of arc chute assemblies is structured to be movable from a first position to a different second position relative to said housing responsive to said arc gases which exhaust from said housing.
