Abstract

1,133,817. Fuses. LUCIEN FERRAZ & CIE. 24 July, 1967 [29 July, 1966], No. 33915/67. Heading H2G. A fuse cartridge comprises an insulating body 1 in which are formed a number of fuse passages 1b each containing a fuse element 2 of e.g. silver, embedded in arc-quenching material e.g. powdered silica or sand, and a cooling passage 1a in the body and through which a cooling fluid e.g. air, circulates during operation of the cartridge. The fuse elements may contact the walls of their passages to improve heat dissipation. The passages are closed by heads 4, extensions 4a of which are used to connect the fuse into circuit. A liquid-cooled version (Fig. 3, not shown) has its closure heads (7) provided with apertures (7b) whereby a coolant e.g. demineralized water may be passed through the cartridge. Seals (8), e.g. 0-rings, prevent access of the liquid to the fuse elements.
