Abstract
1383180 Gas-blast circuit-breakers COQ NV 4 Sept 1972 [7 Sept 1971] 40975/72 Heading H1N A gas-blast circuit-breaker has relatively movable co-operating coaxial tubular contacts which are provided with axial slots dividing one contact into rigid fingers 4 and the other contact into resilient fingers 13, the rigid fingers being stepped and the resilient fingers being provided inwardly directed contact blocks 14 so that as the circuit-breaker is opened, the current path consists of three axial portions 10, 4, 13 interconnected by radial portions 8, 14. The middle portion 4 is nearest the axis of the circuit-breaker so that the magnetic forces set up cause the arc to move on to arcing electrodes 22, 23. Main current-carrying contact fingers 21 separate from the fingers 13 before the arc is drawn between the fingers 4, 13. The contacts may be provided with outer sleeves 26, 27 which act as a valve.
