Abstract
1307486 Electric cut-outs COMPAGNIE FRANCAISE THOMPSON HOUSTONHOTCHKISS BRANDT 19 April 1971 [4 Feb 1970] 20834/71 Heading H1N A device for interrupting a circuit comprises a conducting casing 1 formed with a line of weakness; an explosive charge 12 within the casing and which can be exploded to break the casing, along the line of weakness, into two electrically separate parts and thus interrupt the circuit; and a quantity of insulating liquid 17, such as oil, which is expelled during the explosion to extinguish any arc between the two parts of the casing, The casing further contains two conical members 6, 8, respectively conducting and insulating, which direct the force of the explosion. The insulating member 8 is bored to accept the leads 14 of an electrical triggering device 13. In an alternative form the casing is spherical (Fig. 3). Three devices can be triggered simultaneously to interrupt a three phase supply (Fig. 6, not shown). The device or devices may be covered with a glass wool cover to.prevent projection of oil.
