Abstract
1,254,790. High voltage switches. COQ N.V. 23 Dec., 1969 [3 Jan., 1969], No. 62641/69. Heading H1N. A metal-clad, double break isolating switch comprises a pair of movable contact rods 5, 6 co-operating with fixed contacts 14, 15; a conducting carrier 4 connecting the rods 5, 6 together and enclosing a driving mechanism; an insulator 3 supporting the carrier and dividing the metal enclosure into two sealed compartments each enclosing a fixed and a movable contact; and an earthing switch comprising a fixed contact 34, 35 and a blade 30, 31 pivoted to the carrier 4 and being directly driven to and from its closed position by the rod 5 during its final opening and initial closing movements, respectively. Each earthing blade 30, 31 has an extension 32, 33 and a cam portion 44, 45 which co-operate respectively with holes 49, 50 and the end 46 of rod 5 to operate the earthing switch. The driving mechanism consists of two screw and nut drives 7-9 coupled by bevel gears 16, 17, 18 to a shaft 19 and by 20 to an indicator 22. Further indication is provided by flags 55, 56 visible through windows 57, 58 when the earthing switch is closed. The earthing blades 30, 31 are prevented from moving, until positively driven, by magnets 53, 54.
