A unique electrical switchgear system may include a circuit breaker compartment having a compartment wall. The electrical switchgear system may also include a tapered floor pan mounted on the compartment wall. The floor pan may have two side walls disposed oblique to each other; a back wall; and a top wall coupled to the side walls and defining a discharge opening adjacent to the back wall. The two side walls, the top wall and the compartment wall may form a tunnel for channeling cooling air in a first direction. The back wall may be operative to redirect the cooling air in a second direction different from the first direction for discharging the cooling air from the discharge opening.

Electrical switchgear system

An electrical switchgear system includes a first compartment supplied with cooling air and in fluid communication with an exhaust plenum. A second compartment is in fluid communication with the exhaust plenum. A deflector is operative to deflect an amount of the cooling air from the first compartment and direct it into the second compartment. An electrical switchgear system having switchgear in an enclosure includes a first compartment disposed inside the enclosure and supplied with cooling air. A second compartment is disposed inside the enclosure. A deflector is operative to capture an amount of the cooling air from the first compartment and direct it into the second compartment.
