Abstract
1,187,448. Vacuum switches. GENERAL ELECTRIC CO. 27 June, 1967 [5 Aug., 1966], No. 29567/67. Heading H1N. A vacuum switch 14, e.g. forming part of an on-load transformer tap-changing device, has actuating mechanism comprising a movable switch-actuating member 50, a lost-motion coupling 54, 55a between the member and the movable switch contact 37 and a releasable mechanical latch 63, 64 for holding the member 50 in an " over-travel " position in which the switch contacts are closed and an opening spring 51 is stressed. When the latch is released, the member 50 moves down until a cage 54 of the lost motion coupling strikes a flange 55a to open the contacts rapidly. The release of the latch is effected by a cam surface 67a on a lever 67 freely pivoted on the shaft 60 which interconnects a switch operating lever 62 and a latch lever 63. The lever 67 is operated by linkage 28, a cam 26 and gearing from a motordriven shaft 15a. When the lever 67 is turned anticlockwise it releases the latch to permit the spring 51 to open the contacts 36, 37, but when the lever 67 is turned clockwise, it abuts a rod 65 and positively returns the levers 62, 63 and member 50 to the position shown. A further cam 25 may operate transfer switches 12, 13 and a Geneva mechanism may operate a tap selector. The whole assembly may be disposed in the main transformer tank immersed in oil or other insulating fluid.
