Title: Improvements in and relating to electric circuit-breakers
IPC: H01H71/26
Filed: 1934-08-18
Abstract: 439,653. Automatic circuit-breakers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 18, 1934, No. 23877. Convention date, Aug. 19, 1933. [Class 38 (v)] Arc-rupturing devices.-Circuit-breakers, particularly of the high-speed type, and provided with a plurality of parallel-connected current paths, have tripping means which will operate at a given load current irrespective of the division of that current between the paths. Thus, if the division is unequal, due, for example, to greater contact-resistance in a path, the tripping means will still be responsive to the sum of the load currents through the paths and will operate if that sum exceeds the given value. The breaker shown is suitable for rupturing loads of 10,000 amps. and comprises two paths, each containing an inductive shunt 12, 25, a pair of movable contacts 16, 17 and 30, 31 with flexible connectors, as 14, and fixed contacts as 19. Arranged intermediately is a pair of arcing contacts 39, 35 with a conductor 36 connected to a fixed conductor 37 of relatively high resistance compared with that of the two paths. The movable contacts are connected by rods, as 55, with the pivot pin 52 on a pair of levers 48, 49 pivoted at 50. The levers are acted on by springs 45, 46 tending to separate the contacts, but are held closed by an electromagnet 60. Located in a slot 62 in the magnet are a pair of U-shaped flux-shifting, bucking- bars 65, 66, the free ends of which are connected by conductors 70, 72 and 75, 76 across the shunts 12, 25, respectively. To minimize the tendency for unequal division of load, each path is made as long as possible so that its resistance is high compared with possible differences in contact-resistance. Due to the arrangement of the bucking-bars the sum of the m.m.f's. produced by them for a given total current is the same irrespective of the division of that current between them, and by making the resistance elements 90, 91 of the shunts of a material having only a slight positive temperature-coefficient of resistance, the calibration of the breaker does not vary appreciably with the temperature. The inductances of the shunts are constituted by iron laminations 95, 98, and similar inductances 97, 79 are provided in the bucking-bar circuits and are chosen in accordance with the desired division of current between the circuits and shunts, preferably so that the inductance predominates over the resistance voltage down to relatively low rates of current-rise. A calibrating coil of the character disclosed in Specification 434,114 is located within the bucking-bars.

Filed: 1927-09-12
Abstract: 297,955. Coates, W. A., and Metropolitan-Vickers Electrical Co., Ltd. Sept. 12, 1927. Screw - and - nut mechanism. - The closure of an electric circuit-breaker is effected by motor comprising a stator 11 and a rotor mounted on a shaft 13, which is screwthreaded at 15 to engage a fly-wheel 16. As the motor accelerates, the fly-wheel, owing to its inertia, accelerates m o r e slowly and moves upwards along the screw thread. This axial movement is imported, by a fork 19 engaging a groove in the fly wheel, to a link 20 to effect the preparatory closing motion of the circuit-breaker. Thereafter the motor is suddenly stopped, thus causing the fly wheel to travel rapidly down the screw thread and impart to the link 20 a quick main closing motion in the opposite direction to the preparatory motion.

A casing a containing a number of air passages al, each with a flap c and a fuel valve e actuated thereby, is connected to a mixture chamber q. The passages are separated by partitions x, z, and each has a spring-loaded throttle valve u the spindles b of which are provided with arms l adapted to be actuated by a dog k on a slide t, so as to open the throttles in succession. Each passage is provided with a choke tube p, and with a fuel nozzle f, which forms a seat for the fuel valve e.
