摘要： An apparatus for triggering chemical augmented electrical fuses includes a light source which emits a light signal in the form of visible or infrared light energy upon receiving a signal from a control system, trigger signal source or other fuses. The light signal is coupled to a light detector by an optical coupling device such as a fiber optic cable. Upon receipt of the light signal, the light detector generates a signal which causes the application of electrical energy to exothermic material in a fuse, thereby detonating the material and causing interruption of current through the triggered fuse.

摘要： An apparatus for preventing operation of a full range chemically augmented electrical fuse due to induced current surges includes a low inductance device electrically connected in series between an air gap device and a first terminal of a trigger circuit for triggering exothermic material within the fuse. A second air gap device is electrically connected in series with a second low inductance device. This series connection of the second air gap device and the second low inductance device is electrically connected in parallel with a high inductance device, the parallel connected combination being connected in series with a second terminal of the trigger circuit. All of these elements are electrically connected in parallel with the main fuse element which is electrically connected in series with the protected electrical power distribution system.

摘要： A fuse body encloses a fuse element of a current-limiting fuse wherein the fuse body is formed from an inexpensive material and provided with a shield between the inner surface of the fuse body and the fuse element. Thus, when the fuse element melts and arcs during interruption, the fuse body is protected from the hot gaseous arc products by the protective shield thereby preventing burning of the fuse body. The protective shield can be a spray coating such a ceramic spray coating applied to the inner surface of the fuse tube, a glass coating, or ceramic paper. The fuse body can be made from glass filament wound epoxy material.
