Abstract

An enclosed switchboard (1) has a housing (2), the inside of which is partitioned into plural compartments (a breaker compartment (3), a busbar compartment (4), and a cable compartment (5)). A chamber (8) for alleviating arc-gas dispersion/pressure discharge is arranged above the breaker compartment (3), the busbar compartment (4), and the cable compartment (5). Exhaust ducts (9, 10, 11),. each of which communicates with the chamber (8) for alleviating arc-gas dispersion/pressure discharge, are provided in ceilings of the breaker compartment (3), the busbar compartment (4), and the cable compartment (5). Flappers (12, 13, 14) are provided at upper ends of the exhaust ducts (9, 10, 11), and a pressure-alleviation shield box (15) is provided in an opening section (8a) formed in an upper portion of the chamber (8) for alleviating arc-gas dispersion/pressure discharge. Ventilation sections (12a, 13a, ida) for communicating between the exhaust ducts (9, 10, 11) and the chamber (8) for alleviating arc-gas dispersion/pressure discharge are formed on main surfaces of the flappers (12, 13, 14), and mesh members (12b, 13b, 14b) are provided in these ventilation sections (12a, 13a, 14a).
