Abstract
467,809. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 22, 1937, No. 5265. Convention date, Feb. 21, 1936. [Class 38 (v)] The arc formed between the fixed contact 5 and movable contact 9 on opening the circuit is drawn through a tubular member 2 made of a material which emits an arc - extinguishing gas under the influence of the arc, the member 2 projecting into the interior of a blow - out chamber 6 having a number of exhaust openings 7 leading to the atmosphere. In the construction shown, the movable contact 9 is tubular, and, in the closed position of the switch, surrounds an insulating rod 3 coaxial with the tube 2, the rod 3 being preferably made of a gas-emitting material. The chamber 6 may be of spherical or oval form, and may be secured to the framework of the switch by a pin insulator.
