摘要： 57 A fusible element for a current-limiting fuse comprises a metal ribbon having groups of holes therethrough and therealong. The distance along the ribbon between adjacent holes in a group is less than the distance along between adjacent groups. The lateral width of the ribbon between the hole groups is greater than its laterial width where the holes are located. The ribbon initially melts at the holes and multiple arcs burn back the ribbon at a first rate until the ribbon containing the holes is consumed, following which merger of the arcs occurs. This merger and the greater width of the ribbon between the groups results in burn-back of the ribbon at a second reduced rate. In this way, both 9 kv and 15 kv fault currents may be interrupted without exceeding the spark-over voltage of phase-to-ground arrestors when 9 kv fault currents are interrupted.

摘要： electrical switch (10) includes an alternating series of first and second switch cells. Each first cell (64) includes a first conductive member (67) with a first bore (68) and a first insulative member (71) conformally located in the first bore and movable through the first bore. Each second cell (66) includes a second insulative member (72) with a second bore (73) and a second conductive member (74) conformally located in the second bore and movable through the second bore. The first and second bores have substantially the same cross-section. The cells are mounted end-to-end in the alternating series so that the bores align. Severable metallic members (76) electrically interconnect the second conductive body of each second cell to the first conductive body of both first cells adjacent to the second cell. The first insulative bodies and the second conductive bodies are simultaneously moved to simultaneously sever the metallic members. A plurality of arcs are thereby produced between the first and second conductive bodies of adjacent cells. Additional arcs may be produced by covering the first bore of the first conductive member and the second conductive member with insulative layers.

摘要： A reusable control module mountable to a power-cartridge-operated interrupting module which includes a normally closed switch in shunt with a fuse. The control module houses a control circuit which ignites the power cartridge to open the switch. The control module includes two conductive shells threaded together to enclose the circuit, thereby providing a Faraday cage for the circuit and shielding the circuit from the environment. A current transformer is mounted in an exterior pocket in one of the shells over a mounting terminal thereon which extends out of the pocket to act as a single-turn primary for the transformer. The output of the transformer is connected to an input of the circuit. Circuit boards of the circuit are mounted within the shells, in part by a plastic plug, one end of which passes through one of the shells coaxially with a mounting neck. The other end of the plug has slots which engage and hold one edge of the boards. The plug contains a conductor connected to the output of the circuit. When the modules are moutned together via the neck, the conductor at the one end of the plug is electrically connected to the power cartridge and the shells can now carry the current in a protected circuit to the switch and the fuse. The plug is located on the axis of rotation of the shells when the shells are threaded together so that its holding and signal-carrying functions are not compromised.
