Vacuum switch chamber for short-circuit switching of large currents, includes ceramic insulating body vacuum-sealed tight at both ends with first and second covers

摘要

A vacuum chamber (10) has a ceramic insulating body (11) sealed tight at one end by a disk-shaped cover (12) punched through by a fixed contact point (13) and connected to this contact point with a vacuum seal by a flange (14). This cover is also fastened to a first cylinder (16) with a flange edge radiating outwards on its insulating end.
