Abstract (en)
[origin: US4748303A] An isolating switch of a metalclad installation having an earthed metal enclosure is filled with a high dielectric strength gas. The isolation gap "d" separating the stationary contact from the movable sliding pin is surrounded by an annular electrode fitted between this isolation gap "d" and the enclosure. The annular electrode extends over the whole length of the isolation gap "d" and is electrically connected to the stationary contact to prevent any migration of the arc drawn between the contacts towards the earthed enclosure. The metal enclosure is advantageously spherical in shape, the contacts being disposed appreciably in the center of the sphere.
