Abstract

927,167. Protective cut-out arrangements. CHARBONNAGES DE FRANCE. Oct. 28, 1959 [Oct. 28, 1958], No. 36657/59. Class 38 (5). A protective system comprises means 34 for injecting high-frequency current into a protected power supply network R and current transformers 35 connected to a detection circuit 36 which responds to an abnormally high high-frequency current due to a shortcircuit and effects the operation of a highspeed. cut-out device C to interrupt the power supply to the network. In a three-phase arrangement as shown, the device C may comprise three single phase cut-outs each having a conductor which is ruptured by an explosive charge when an igniter is energized by the circuit 36, the cut-outs being those of Specification 927,169 [Group XXXVI]. Specification 866,031 also is referred to.
