ELECTRICAL SWITCHGEAR SYSTEM

摘要

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.

1. An electrical switchgear system, comprising:
a circuit breaker compartment; a floor pan located within the compartment and having 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; and wherein the two side walls, the top wall and a bottom wall form a tunnel for channeling cooling air in a first direction, and wherein the back wall is operative to redirect the cooling air in a second direction different from the first direction for discharging the cooling air from the discharge opening.
