Abstract

948,759. Arc-rupturing in switches. WHIPP & BOURNE Ltd. March 15, 1960 [March 17, 1959], No. 9113/59. Heading H2B. Each refractory plate of a circuit-breaker arc-chute comprises short and long parallel sides 11, 12 whose ends 14, 16 have portions 13, 15 connected by a side 19, the plate areas defined by sides 11, 13 and 12, 15 being thicker than the remaining part and having ribs 28 and grooves 29 on opposite surfaces. The chute comprises adjacent plates 10, 23 assembled with interengaging ribs and grooves, and having their sides 19 oppositely inclined to form a V-shaped slot, each side 11 being aligned with a spacer 30 of similar thickness and design and the members 10, 23, 30 being bonded together by an air-drying cement. If desired, the sides 12 may be progressively or suddenly shortened to alter the shape of the chute and the V-shaped slot, Figs. 5, 6, 7 (not shown).
