Abstract (en)
[origin: EP0334181A1] High-tension pressurised dielectric gas switch of the type including at least one cut-off chamber comprising an insulating surround filled with the said gas and inside which are placed an assembly comprising a stationary main contact (2) and a stationary arc contact (4), a movable assembly comprising in particular a movable main contact (7) and a movable arc contact (5), the cut-off chamber further comprising a snuffing cylinder opening into a snuffing nozzle and a pair of secondary contacts, characterised in that it includes first means (37, 38, 104) for limiting the maximum distance of separation of the secondary contacts to a value less than the maximum distance of separation of the arc contacts and second means (6C, 101) for preventing any sparking on triggering. <IMAGE>
