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.

Abstract: An electrical switching device is filled with a dielectric insulating medium comprising an organofluorine compound, in particular a fluoroether, a fluoroamine, a fluoroketone or a fluoroolefin, and comprises at least an arcing contact arrangement with a first arcing contact and a mating second arcing contact. At least a first intermediate volume is provided downstream from the first arcing contact, and/or at least a second intermediate volume is provided downstream from the second arcing contact. The intermediate volumes are for intermediate pressure enhancement and exhaust gas jet formation for turbulent convective heat transfer to metal walls of the exhaust system. In embodiments, the first and/or second intermediate volume is delimited by at least one moveable wall arranged transversally to the longitudinal axis and shiftable parallel to it by an actuation device.
