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.

Claim (Index 1):
An electric switching device filled with a dielectric insulating medium, comprising\n at least an arrangement of arcing contacts with a first arcing contact and a corresponding second arcing contact, wherein for opening and closing the electric switching device at least one of the arcing contacts is movable parallel to a longitudinal axis and cooperates with the other arcing contact, wherein at least a first exhaust volume is provided downstream of the first arcing contact, and/or at least a second exhaust volume is provided downstream of the second arcing contact, with respect to a local flow direction of the insulating medium, in such a way that dielectric insulating medium can flow from an arcing volume arranged between the first and the second arcing contact into the first and/or the second exhaust volume, wherein the first and/or the second exhaust volume comprise or comprises a plurality of first openings in its wall, through which the insulating medium can exit the first and/or the second exhaust volume into at least one third volume, wherein the at least one third volume is arranged around the first exhaust volume an/or around the second exhaust volume and is delimited in radial direction, with respect to the longitudinal axis, at least partially by the wall of the first exhaust volume and/or of the second exhaust volume and by an exterior wall, wherein the exterior wall has second openings through which the insulating medium exits the third volume towards an enclosure of the electric switching device, wherein at least one baffle device is provided inside the third volume and is arranged in such a way that a turbulent flow of the insulating medium is generated while the insulating medium passes the baffle device on its way towards the second openings, wherein the baffle device is a trap for particles transported by the dielectric insulating medium, wherein turbulent flow conditions are chosen such that gravitational force allows to trap or contributes to trap particles in the baffle device, wherein the baffle device comprises baffle plates or fins, that are arranged to form cavities for capturing the particles by gravitational force.
