ELECTRICAL ROOM

WIPO Patent Application WO/2013/099393

A1

An electrical room houses, for example, a switch gear (1) as electrical equipment, and has a maintenance space (10) for maintenance check on the front side of the switch gear (1). The electrical room has a space (11) for heat dissipation and pressure discharge above the switch gear (1), which acts as an air channel for the air warmed as a result of the heat generated by the switch gear (1) and the high-temperature and high-pressure gas generated upon an internal short-circuit in the switch gear (1). The maintenance space (10) and the space (11) for heat dissipation and pressure discharge are separated by a separator (12). There is also an electrical room exhaust outlet (15) that opens from the space (11) for heat dissipation and pressure discharge to the outside of an electrical room housing (8). The electrical room exhaust outlet (15) includes a vent outlet that always communicates with the outside, and an electrical room pressure discharge board (16) that opens with the pressure from the generation of a high-temperature and high-pressure gas.
