Abstract
In accordance with presently disclosed embodiments, an arc resistant exhaust and intake for medium and high voltage switchgear is provided. In one embodiment, an arc resistant drive system may comprise: a drive cabinet comprising a vent; and an arc resistant shutter plate assembly coupled to the drive cabinet and aligned adjacent to the vent, wherein the arc resistant shutter plate assembly comprises a plurality of shutter plates configured to automatically transition from an open position to a closed position when air pressure inside the drive cabinet exceeds a predetermined value, such that the shutter plates substantially restrict air flow through the vent in the closed position.
