Abstract
601,838. Arc-rupturing in switches. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 5, 1945, No. 25940. Convention date, Oct. 10, 1944. [Class 38 (v)] In a circuit-breaker such as that described in Specification 565,823, the arc runner 3 for the moving contact, has secured to it diverging magnetic flanges 1, 2 which tend to maintain the arc midway between them, so preventing burning of the insulating arc-shoot plates 5, 6. The flanges 1, 2, also serve as pole pieces for the blow-out coil 12, and may be supplemented by normal pole plates outside the arc-shoot. When a blow-out coil is not used the arc-runner 3 can be made of magnetic material, and may be integral with the flanges and of simple channel section. Alternatively, the combined flanges and runner may be formed as a number of spaced channel-section members, mounted on an insulating bar, Fig. 4 (not shown). Specification 267,515, [Class 38 (v)], also is referred to.
