摘要:
Metal-clad electrical equipment comprises a metal vessel (4) and an exhaust constituted by an arcing contact support tube (9) and a casing (16) surrounding the support tube (9) and co-operating therewith to define an annular volume (20). At one end, the support tube has an inlet for passing arc gas. Exhaust holes (17) are provided through the casing to allow arc gas to escape into the vessel. The equipment includes a particle trap (22) situated in the exhaust between the arcing contact support tube (9) and the exhaust casing (16).
