摘要： 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.

摘要： A circuit breaker and a switching chamber are disclosed which include a switching chamber housing composed of electrically conductive material, which surrounds an erosion volume and has an axially directed outlet which connects the erosion volume to an outlet opening on the outer face of the switching chamber housing, or which has at least one radially directed outlet. The outlet can include an insert, which is located in an aperture in the switching chamber housing and which is composed of electrically insulating material. A connecting stub surrounds an outlet channel and projects beyond the outer face of the switching chamber housing. A collar projects outward and rests on the inner face of the switching chamber housing. The aperture is located in a depression on the outer face of the switching chamber housing, such that the triple point where the switching chamber housing meets the insert is shielded. The outlet channel can carry heated insulating gas flowing out away from areas where there is an increased electrical field strength adjacent to the rim of the depression.

摘要： A dielectric gas produced at the time of current interruption is exhausted into an exhaust structure 1 through an opening 8 formed on a fixed-side support member 6 combined with a fixed arcing contact 4. The exhaust structure 1 has an enlarged portion with a gas flow cross section formed at least before a position at 1/2 of the overall length of the exhaust structure 1 that is uniformly enlarged toward the rear of the exhaust structure 1 with respect to the joint between the exhaust tube 1 and the fixed-side support member 6. As a result, the gas is immediately exhausted into the exhaust structure 1 and the interelectrode insulation recovery performance is ensured.
