Abstract
A switchgear housing assembly includes a first switchgear housing including a cable compartment portion and a circuit breaker portion, a busbar portion, and a second switchgear housing a cable compartment section, a busbar section, and a circuit breaker section. An exhaust duct is arranged between the first and second switchgear housings. The exhaust duct is selectively fluidically exposed to at least one of the cable compartment portion, cable compartment section, the circuit breaker portion, and the circuit breaker section. A floating flap assembly is operatively associated with at least one of the first and second switchgear housings. The floating flap assembly includes a floating flap member. The floating flap member is selectively slideable between a closed position and an open position in response to a pressure rise in one of the cable compartment portion, cable compartment section, circuit breaker portion, and circuit breaker section.
