    Abstract: An electric switching device (1) filled with a dielectric insulating medium comprises first and second arcing contact (3, 4), first exhaust volume (7) downstream of first arcing contact (3) and second exhaust volume (8) downstream of second arcing contact (4). The exhaust volumes (7, 8) comprise several first openings (14) in their walls (17), through which the insulating medium exits into third volume (9). The third volume (9) is arranged around the first or second exhaust volume (7, 8) and is radially delimited by the wall (17) of the exhaust volumes (7, 8) and by an exterior wall (11) having second openings (10) through which the insulating medium exits the third volume (9). One baffle device (2) is provided inside third volume (9) such that vortex flow of the insulating medium is generated when it passes the baffle device (2) on its way towards the second openings (10).

    Abstract: The invention relates to an electrical switching device with a switching chamber (10), which comprises at least two arcing contacts (192, 192) movable in relation to each other and defining an arcing region (22) in which an arc (20) is formed during a current breaking operation, with the switching chamber (10) being filled with a switching medium (20) for arc quenching and for dielectrical insulation. The switching chamber (10) further comprises an exhaust volume (40, 62) fluidically connected to the arcing region (22) to allow the switching medium heated by the arc (20) to flow out of the arcing region (22) to the exhaust volume (40, 62), thereby transferring heat to a surface area of a metal component of the switching chamber (10). The device is characterized in that at least a portion of a surface contained in the switching chamber (10) is covered with a porous layer (72).

    Abstract: An electric switching device filled with a dielectric insulating medium includes first and second arcing contact, first exhaust volume downstream of first arcing contact and second exhaust volume downstream of second arcing contact. The exhaust volumes includes several first openings in their walls, through which the insulating medium exits into third volume. The third volume is arranged around the first or second exhaust volume and is radially delimited by the wall of the exhaust volumes and by an exterior wall having second openings through which the insulating medium exits the third volume. One baffle device is provided inside third volume such that vortex flow of the insulating medium is generated when it passes the baffle device on its way towards the second openings. Turbulent flow conditions are chosen such that gravitational force allows to trap or contributes to trap particles in the baffle device. The baffle device comprises baffle plates or fins, that are arranged to form cavities for capturing the particles by gravitational force.
