A switchgear enclosure includes an exterior housing. A plurality of compartments within the exterior housing includes at least a first switching device compartment, a bus compartment, and a first cable compartment. A plurality of interior partitions arranged to subdivide the exterior housing into the plurality of compartments includes at least a first partition between the first switching device compartment and the first cable compartment, and a second partition between the bus compartment and the first cable compartment. An exhaust system includes a vent path structure arranged within the exterior housing to at least partially surround the bus compartment and the first cable compartment, a channel formed between the vent path structure and the exterior housing, and a first vent device in the first partition. The first vent device is configured to fluidically connect the first switching device compartment to the channel via the vent path structure.

A shutter interlock device for an electrical enclosure includes a shutter link defining a lock slot, an actuating member rotatably coupled to the electrical enclosure, and a sliding link. The sliding link includes a first end coupled to the actuating member, a second end opposite the first end, and a pin coupled to the second end, where a rotation of the actuating member causes the pin to selectively disengage the lock slot.

Shutter interlock devices, systems, and methods of use thereof

A switchgear enclosure is provided. The switchgear enclosure includes a plurality of switchgear panels and a plurality of ducts extending through the switchgear panels. Each switchgear panel includes an exterior housing, a busbar compartment defined within the exterior housing, and an exhaust system. The busbar compartment surrounds a busbar extending through the switchgear panel. The exhaust system includes a vent path structure configured within the exterior housing to at least partially surround the busbar compartment, a first channel defined between the vent path structure and the exterior housing, and a first vent opening formed on the vent path structure. The first vent opening directs arc gases within said busbar compartment to the first channel. The ducts are in fluid communication with the first channels of the switchgear panels to distribute arc gases between the first channels.

Switchgear enclosure with interconnected exhaust system

A fixed contact for joining a bus bar and a sliding contact of an electrical switchgear is provided. The fixed contact includes a plurality of circumferential segments operatively coupled to each other. The fixed contact also includes an axial extent extending along a longitudinal axis of the fixed contact from a first end of the fixed contact to a second end of the fixed contact, the axial extent comprising a mounting region, a central region and a sliding contact engagement region. The mounting region extends axially from the first end of the fixed contact to the central region, the mounting region configured to be operatively coupled to the bus bar. The sliding contact engagement region extends axially from the central region to the second end of the fixed contact, the sliding contact region configured to be slidably engaged with a sliding contact.
