Patent number: 10553378Abstract: 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.Type: GrantFiled: September 24, 2018Date of Patent: February 4, 2020Assignee: ABB Schweiz AGInventors: Francesco Pisu, Mahesh Dhotre, Xiangyang Ye, Johan Karl Filip Costyson, Reto Karrer
