Abstract: A chemically augmented electrical fuse is triggered using optical energy acquired as a result of the triggering of another chemically augmented fuse. Light energy created as a result of the detonation of the first chemically augmented fuse is conducted to an exothermic pellet of a second fuse. The light energy received at the second fuse is focused on the exothermic pellet by means of a lens. The focused light energy causes the detonation of the exothermic pellet in the second fuse thereby causing the interruption of current through that fuse.

Abstract: A power capacitor with a plurality of section windings stacked within a housing is provided with an interconnection and fusing arrangement in which insulative spacer elements extending from between adjacent sections support a common electrical bus and an insulative locater element. Fuse wires attached to ends of the section windings extend around an edge of the locater element to the bus and are maintained thereby in spaced relation to avoid interaction between neighboring fuses when one clears.
