| 147 | Low melting point element fusion apparatus and circuit breaker including the same | US09342596 | 1999-06-29 | US06194988B1 | 2001-02-27 | Noboru Yamaguchi; Tomonori Takamizawa; Tsugio Noda |
| A fusion apparatus is equipped with a fuse, a solid combustion agent, an igniting device, and a spring. The solid combustion agent and the igniting device are accommodated within an inner casing. The inner casing is disposed in the vicinity of, or in contact with, the fuse. The inner casing and the fuse are covered by an outer casing. The spring is disposed between the outer casing and the inner casing and urges the inner casing containing the solid combustion agent therein toward the fuse. When the igniting device receives a current supplied from the outside, the solid combustion agent is combusted by the ignition made by the igniting device and the resulting combustion heat softens the fuse. At this time, since the inner casing is pressing the fuse by means of the spring, the fuse is easily broken. | ||||||

| 150 | Pyrotechnically-assisted current interrupter | US252014 | 1988-09-27 | US4920446A | 1990-04-24 | Herbert M. Pflanz |
| A current interrupter wherein current is normally carried by a bus bar, and a portion of the bus bar is segmented by a pyrotechnic charge under excess current conditions. The charge is detonated by a detonator which is triggered by voltage across a resistive element in series with the bus bar. At the time the detonator is triggered, the resistive element provides sufficient resistance to trigger the detonator while operating at a temperature below its melting point. A control device may be employed to control current flow through the detonator. | ||||||
| 151 | Passively detonated explosively-assisted fuse | US562827 | 1983-12-19 | US4538133A | 1985-08-27 | Herbert M. Pflanz |

| 152 | Brake and operation indicator for a high-voltage switch | US437925 | 1982-11-01 | US4427963A | 1984-01-24 | John M. Jarosz; William R. Panas |
| A brake and operation indicator for a movable contact of a switch, the movable contact being rapidly moved by ignition of a power cartridge to open the switch. A thin-walled sleeve is positioned conformally about a movable pin, a portion of which is lightly held in a bore of an end member of a housing for the switch. The sleeve is shorter than the distance between a head on the pin and the end member. The bore is normally closed by a thin membrane. When the contact is moved, it ultimately abuts the head, moving the pin through the membrane to a position beyond the end member where a portion of the pin is visible. Movement of the pin also collapses the sleeve between the head and the end member in accordion-like fashion to dissipate the kinetic energy of and stop the contact. The presence of the pin within the sleeve renders the collapse controlled, uniform, and efficient. The visible portion of the pin informs that the switch is open. | ||||||
| 153 | Circuit breaker devices with a pyrotechnically destructible conductor having a fuse system in parallel | US290811 | 1981-08-04 | US4385216A | 1983-05-24 | Jean-Pierre Cinquin |
| A pyrotechnical cartridge or motor (5) is actuated by electric firing from its head (5c), and pushes the insulating piston (3) which separates by shearing the intermediate connecting portion (1b) of the destructible conductor (1) and pushes it into the bore (1e) together with the rod (9), the conical end (9a) of which becomes wedged within the plug (10) so as to form a brake. The fuse cartridges (13) then open the circuit in a fully safe manner.The present invention is useful for instance under the control of overcurrent detectors. | ||||||

| 155 | Explosively activated fault current limiter | US899539 | 1978-04-24 | US4176385A | 1979-11-27 | Rolf Dethlefsen |
| An explosively activated current interrupter is provided for use in a fault current limiting system employing a plurality of such interrupters. Each interrupter includes an automatic switching system for sequentially installing each of a plurality of the interrupters on a power line. A conductive member in the interrupter housing conducts current carried by the power line. An explosive charge in the housing breaks the conductive member into a plurality of separated portions upon detonation, thereby interrupting the power line current. A switch opened and closed by means of explosive gas pressure alternately installs and removes the interrupter from the power line. Each interrupter is connected by a gas conduit to the next sequential interrupter to be detonated. Upon detonation of one interrupter, a portion of the explosion gases are transferred by the conduit to the next interrupter, operating the switch to install the next interrupter on the power line after an appropriate delay. | ||||||
