PROTECTION FILTER ASSEMBLY FOR A SWITCHGEAR PANEL AND SWITCHGEAR PANEL COMPRISING THE SAME

摘要

Protection filter assembly (1) for a switchgear panel (2), comprising: an enclosure (5) defining an evacuating path for conveying out of the switchgear panel a flow of flames, gases, particulates which may originate in case of explosions or electric arcing events occurring inside the switchgear panel. Mitigating barrier elements (12) are provided for mitigating the intensity of the flow which barriers are distributed along the evacuating path so as to define a plurality of expansion chambers for progressively expanding the flow along the evacuating path itself.
