Abstract
A fused disconnect switch device includes a housing defining an interior volume, and a current path. An arc interruption assembly is located in the interior volume and includes a shell, and a conductor in electrical communication with the current path. At least one arc plate is located between the magnets and the conductor. The magnets cooperate to generate a magnetic field facilitating an interruption of a first arc between the conductor and the first side of the arc chamber and a second arc between the conductor and the second side of the arc chamber.
Claims20
A fused disconnect switch device comprising:
- a housing defining a first interior volume;
- a current path defined in the housing;
- a fusible element in electrical communication with the current path;
- and
- an arc interruption assembly located in the first interior volume, the arc interruption assembly comprising:
- a shell defining second interior volume and at least one barrier in the defining at least one arc chamber in a portion of the second interior volume,
- a first magnet located on a first side of the shell and a second magnet located on a second side of the shell,
- a moveable conductor selectively positionable within the shell and switchably connecting or disconnecting the current path in the arc chamber, and
- at least one set of arc plates located between the first or second magnet and the conductor;
- wherein the first and second magnets cooperate to generate a magnetic field across the arc chamber.
A fused disconnect switch device comprising:
- a nonconductive housing configured to accept an overcurrent protection fuse;
- a current path defined in the nonconductive housing, the current path comprising a first fuse contact member and a second fuse contact member, the first fuse contact member and the second fuse contact member configured to complete an electrical connection through the overcurrent protection fuse;
- a movable conductor in electrical communication with the current path;
- a switch actuator selectively positionable between first and second positions to electrically connect and disconnect the movable conductor in the current path;
- and
- an arc chamber assembly disposed about the movable conductor and separately defined from the housing, the arc chamber assembly comprising at least one pair of magnets, a first plurality of arc plates, and a second plurality of arc plates, the at least one pair of magnets establishing a magnetic field across the first and second pluralities of arc plates,
- wherein the first and second pluralities of arc plates respectively comprise aligned arc plates having a leading edge defining a channel through which the movable conductor passes.
A fused disconnect switch device comprising:
- a housing defining an interior volume;
- a current path defined in the housing, the current path including a first fuse contact member, a second fuse contact member, a first stationary switch contact and a second stationary switch contact, wherein the first fuse contact member and the second fuse contact member are configured to complete an electrical connection through an overcurrent protection fuse and wherein the first stationary switch contact and the second stationary switch contact have a stationary turn-back conductive structure;
- and
- an arc chamber assembly comprising:
- at least one movable conductive member carrying first and second movable switch contacts on opposed ends thereof,
- a first magnet located on a first side of the arc chamber assembly,
- a second magnet located on a second side of the arc chamber assembly, the first and second magnets cooperating to generate a magnetic field therebetween,
- a plurality of arc plates located between the first or second magnet;
- and
- a shell comprising a plurality of receptacles for holding the plurality of arc plates and the first and second magnets.
