Abstract

730,546. Arc rupturing in switches. ALLISCHALMERS MANUFACTURING CO. March 12, 1952 [March 26, 1951], No. 6410/52. Class 38 (5). A circuit-breaker has an arc chute with a plurality of spaced slotted insulating plates, the slots forming an arc passage and each of the plates having a plurality of apertures of a diameter equal to at least one quarter of the plate thickness but not greater than twice the plate thickness. The assembly of plates may comprise a number of pairs of plates 60, 61 as shown in Fig. 5, the apertures 62 in adjacent plates diverging towards the exhaust ends of the plates and the arc passage 63 being formed from the open-sided slots by the combination of the plates. Figs. 2 and 3 (not shown) illustrate an arrangement in which each plate has an elongated slot and a line of equal-sized apertures. The Specification indicates how the size of the apertures may be related to various dimensional factors of the arc chute. Specifications 615,025, 700,388 and 700,389 are referred to.
