Abstract

551,966. Arc-rupturing in switches. BRITISH THOMSON-HOUSTON CO., Ltd., (General Electric Co.). Dec. 23, 1941, No. 16562. [Class 38 (v)] The arc 5 drawn between fixed and movable contacts 1, 2 in an arcing chamber 3, is driven by a blow-out coil 4, or air blast, against and into a body of refractory insulating granules 6 held in place by refractory bars 7 on a perforated plate. The granules may be of silica.
