Abstract

655,378. Electrically tripped switches. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 6, 1948, No. 3557. Convention date, Feb. 6, 1947. [Class 38(v)] [Also in Groups XXII and XXXVIII] In a high-voltage circuit - breaker, the trip coil 4 is placed in the framework at or near earth potential and is connected to the circuitbreaker opening device 2 by an insulating rod 1 along which elastic waves are propagated when the base of the. rod is struck by the core 3 of the coil 4. The waves so produced drive a pivoted or rectilinearly - guided weighted block 5 against the device 2, which may be a valve if the circuit-breaker is to be pneumatically-operated, or a latch. The speed of transmission may be varied by adjusting the size of the block 5.
