Abstract
618,749. Arc-rupturing in switches. WHIPP & BOURNE, Ltd., and WHIPP, I. T. L. Nov. 30, 1946, No. 35542. [Class 38 (v)] The arcing chamber of a circuit-breaker has a row of spaced magnetic C-shaped members 4, two equallength arcs being drawn between them and contacts 1, 2 respectively. The field due to the arc-current flowing in the lower limbs of the members causes the arc to rise, but when it crosses the gaps, the current flows in the upper limbs and the reversed field drives the arc back across the gaps. The arc is thus stabilised until extinguished at a current-zero by gas exhausting between the C-members.
