Abstract
872,864. Gas-blast switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 22, 1957 [Nov. 8, 1956; Feb. 8, 1957], Nos. 34176/56 and 4432/57. Class 38 (5). In a gas-blast circuit-breaker having a contact chamber on a tubular insulating column and a blast valve at the foot of the column, a contact is moved by a piston striking an abutment - on the contact after initial movement relative thereto. In the earlier Provisional Fig. pressure air entering by a passage 6 acts on the piston 15 and compresses a spring 16 until the piston engages a rubber washer 17 on a disc 13 connected to the moving contact 10 which then moves with the piston 15. In the Complete Fig., pressure air entering by passages 50, 51 acts on a piston 32 carrying a main contact 34 so that it is moved against the bias of a spring 35 until it engages a rubber washer 54 on the spring-biased interrupting contact 38 which then moves with the piston 32. Piston rings 45, 46 may also act as resilient contact means between the piston 32 and the contact 38 and the cylinder which is part of the main structure 22. The main cylindrical contact 34 may be split at 56 to ensure good contact with the fixed contact 26. Specification 605,623 is referred to.
