Title: Improvements relating to electric circuit breaker operating means
IPC: H01H3/22
Filed: 1946-08-30
Abstract: 616,217. Automatic circuit - breakers. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 30, 1946, No. 26094. Convention date, Aug. 30, 1945. [Class 38 (v)] An operating mechanism for a circuitbreaker has a solenoid which when closing the circuit-breaker under abnormal load conditions may be assisted by mechanical means. The circuit-breaker 1 has a solenoid with a winding 9 and a core 8 below which is mounted a barrel 11 containing a piston 12 bearing on the core. At the lower end of the barrel an explosive cartridge 14 is retained by a breech block 13 having a spring-loaded firing pin 15 normally held in readiness by a latch 17. When a switch (not shown) is closed the winding 9 is energized and the core 8 is raised to close the circuit-breaker, but if the loading of the power circuit 7 is heavy, the current induced in a current transformer 20 energizes a coil 19 which attracts a core to pull down the latch 17 so releasing the firing pin 15. A switch 21 connected in the firing circuit is coupled to the above-mentioned switch to ensure that the cartridge may only be fired during the closing operation. In Fig. 2 (not shown), release of the firing pin is obtained by means of an armature normally held by a permanent magnet having an opposing coil energized from secondary windings of two initially-saturated transformers which together supply a unidirectional current, as described in Specifications 266,359, [Class 38 (v)], and 548,296, to obtain the release of the armature and firing pin; when abnormal closing loads exist. This permanent magnet device may also be used, Fig. 3 (not shown), to control a supplementary spring which takes the place of the explosive charge. In Fig. 4 (not shown), a dash-pot assembly releases the catch and firing pin if the movement of the closing mechanism is slowed down due to magnetic forces. A ratchet mechanism releases the firing pin, Fig. 5 (not shown), in the event of reversal of the closing mechanism. Specifications 26694/01, [Class 38], 541,612, 598,894 and 616,218 are referred to.
