| 282 | Power breaker | US09642941 | 2000-08-22 | US06549387B1 | 2003-04-15 | Goro Nakamura; Takahiro Sato |
| A reset knob 20 is mounted to a tip end of a shaft 16. A torsion spring 21 and a returning motion-preventing lock 22 are bent and accommodated in the reset knob 20. The returning motion-preventing lock 22 can rotate around a reset-knob fulcrum 20a of the reset knob 20 by a load of the torsion spring 21. Therefore, the returning motion-preventing lock 22 jumps out from inside of the reset knob 20 which is firmly connected together with the shaft 16 by a force of the torsion spring 21, thereby preventing the shaft 16 and the reset knob 20 from returning to an initial position. Further, since the returning motion-preventing lock 22 can easily be accommodated in the reset knob 20 manually, a reset operation for returning the shaft 16 to its original initial position can be carried out easily. | ||||||

| The power circuit breaker has an igniter unit disposed in a cylindrical wall formed in a main housing. A holder is disposed in the cylindrical wall so as to oppose to the igniter unit. The holder has a boss engaged with the cylindrical wall, and a fuse element is held by the holder. Each end of the fuse element is electrically connected to one of a pair of interconnection terminals disposed in the main housing. The holder is locked by a locking lance formed in the main housing when each end of the fuse element has engaged with one of the interconnection terminals. The holder rests on the locking lance when the fuse element has been released from the interconnection terminals after activation of the igniter unit. The fuse element is engaged with and stopped by an insertion hole of the holder. The interconnection terminals each are a receptacle type terminal having two resilient contact strip portions one of which is connected to one end of the fuse element and the other of which is connected to an opposing terminal of a power circuit. | ||||||
| 284 | Circuit breaker device | US09499691 | 2000-02-08 | US06388554B1 | 2002-05-14 | Noboru Yamaguchi |
| A circuit breaker device including a first connection terminal, a second connection terminal, a heating portion electrically interconnecting the first connection terminal and the second connection terminal, and a claw lockingly engaged with the heating portion. The claw is configured to be melted by the heating portion to allow the heating portion to move apart from the first connection terminal and the second connection terminal for electrical disconnection. | ||||||
| 285 | Circuit breaker | US09887097 | 2001-06-25 | US20020018331A1 | 2002-02-14 | Hideo Takahashi |
| A circuit breaker surely and quickly disconnects a circuit. If an abnormality occurs when the controller (70) is operating normally, the controller provides an abnormality signal to ignite an igniter (29), which heats a heating agent (27) filled in a thermite case (26). Heat from the thermite case melts a retainer (45), and a compressed spring (39a) in the retainer ejects the thermite case. This electrically disconnects the thermite case (26) from first and second bus bars (11a, 19a), thereby quickly and surely cutting a circuit. If the controller (70) fails to disconnect the circuit, the controller generates heat to make a temperature detective switch (71) conductive to pass current from a secondary power source (80) to a resistor (30b) of the igniter (29). The resistor generates heat to ignite an igniting agent (30a) filled in the igniter, thereby surely and quickly cutting the circuit. | ||||||
| 286 | Electrical high speed circuit breaker with explosive charges including ablative arc extinguishing material | US09477368 | 2000-01-04 | US06252190B1 | 2001-06-26 | Lutz Niemeyer |
| A simple high-speed circuit breaker which is cheap to produce is specified for alternating currents which have to be switched off, which switches such currents off within one half-cycle at the current zero crossing, by means of a gas-generating explosive charge (4). In this case, a switching piston (2) which makes a sliding contact with a consumable contact pin (K1) of a first electrode (E1) when the high-speed circuit breaker is closed, moves in the direction of a hollow electrode (E2). The switching piston (2) has a contact tube (2′) with an exhaust opening (3) which is closed by the hollow electrode (E2) when the high-speed circuit breaker is closed, and is open to an exhaust chamber (8) when the high-speed circuit breaker is open (left-hand half of the figure). The contact tube (2′) moves in a sliding manner in a cutout in the hollow electrode (E2). A plurality of explosive charges (4) may be accommodated in the first electrode (E1). In addition, rated current contacts which are provided between the first electrode (E1) and the switching piston (2) carry a continuous current when switched on. The high-speed circuit breaker is particularly suitable as a circuit breaker in addition to a power breaker, in which case the high-speed circuit breaker is tripped if the power breaker fails. | ||||||
| 287 | Current breaker for a vehicle battery lead | US125602 | 1998-12-23 | US6144111A | 2000-11-07 | Alfred Krappel; Robert Albiez; Maximilian Groebmair; Bernhard Fahrnbauer |
| In a current interrupter for a battery lead for motor vehicles, with a contact element between the two connecting parts for their electrical connection and with an auxiliary drive for separating the two connecting parts, contact element applies only a transverse force that is directed essentially perpendicularly to the connecting parts. A retaining force which is directed opposite to the action of the auxiliary drive is mainly applied at one point and is spatially separated from the contact element. | ||||||
| 288 | Apparatus for interrupting the flow of current in a cable | US166696 | 1998-10-05 | US6078108A | 2000-06-20 | Karl Franz Froschl |
| An apparatus for interrupting the flow of current in a cable, which cable leads from the battery in a motor vehicle to a consumer, also located in the vehicle, such as the starter, engine or the like. A housing is provided, having two connection terminals, electrically insulated from one another, for the lines leading to the battery and to the consumer, and having a switch disposed in the interior of the housing, the switch being assigned a control device which can be tripped by a sensor and whose tripping actuates the switch. | ||||||
| 289 | Isolator device for arrester | US985196 | 1997-12-04 | US5952910A | 1999-09-14 | John A. Krause |
| A device for connecting, and then isolating and disconnecting an arrester includes a non-conductive housing with two electrical terminals. The housing has opposite ends separated by an internal chamber. The terminals are mounted at the housing ends. A resistor engages and extends between the terminals in the housing internal chamber. A cartridge with an explosive charge is mounted in the internal chamber adjacent the resistor. A gap spacer surrounds the cartridge, is adjacent one of the terminals and is spaced from the other terminal. | ||||||
| 290 | On-board wiring system for vehicles | US802772 | 1997-02-21 | US5818121A | 1998-10-06 | Alfred Krappel; Robert Albiez; Maximilian Groebmair; Bernhard Fahrnbauer |
| In an on-board wiring system for vehicles has a battery line for connecting a generator with an energy accumulator and a disconnection switch, actuated as a result of an accident, arranged therein. Additional consuming devices are connected to the energy accumulator by way of a consuming device line. The disconnection switch 2 is constructed such that, in addition to the battery line 3, it also interrupts the consuming device line 9 and in the process also disconnects it from the battery line 3. | ||||||
| 291 | Device for interrupting the flow of current in the positive or impregnated vehicle battery cable | US443223 | 1995-05-17 | US5621197A | 1997-04-15 | Richard Bender; Christian Herget; Lothar Maier; Alfred Krappel; Robert Albiez; Maximilian Grobmair |
| A device for disconnecting the flow of current in the positive or impregnated battery cable of a motor vehicle has an electrically conductive plug-in connection that can be placed in the positive or impregnated battery cable in the form of a housing and a plug connector. The housing contains a gas generator of the kind used, for example, for belt tighteners. The gas generator is arranged in the housing in such a way that the propellant gas produced when the gas generator is ignited electrically separates the connector from the housing and this in turn interrupts the flow of current in the positive or impregnated battery cable. Consequently, a short circuit that might occur in the event of an accident and which could otherwise lead to damage of the cable tree and then set the vehicle on fire, is avoided in good time. | ||||||
| 292 | Apparatus for triggering chemically augmented electrical fuses | US248470 | 1994-05-24 | US5406438A | 1995-04-11 | Radhakrishnan Ranjan; William E. Lazenby; Robert E. Koch; Gerald J. Carlson; John G. Leach; Ronald E. Bennet |
| 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. | ||||||
| 293 | Arrester with external isolator | US394523 | 1989-08-16 | US4975797A | 1990-12-04 | Edward F. Veverka; Gary L. Goedde; Stanley S. Kershaw |
| An arrester for an under oil transformer is connected between a primary bushing lead and an insulator/isolator penetrating the wall of a housing which encloses the oil, arrester, and transformer parts. A ground wire outside the housing is removably connected to the isolator which functions as a circuit disconnector. The ground wire is removed to open circuit the arrester so that the transformer may be tested without having to disable any parts in the housing. Responsive to an arrester failure, the ground wire is blown away to give a visual indication of the failure. The blowing away of the ground wire eliminates the need for the arrester to fail in an open circuit condition. | ||||||
| 294 | ARC severing and displacement method and apparatus for fault current interruption | US454705 | 1989-12-18 | US4958052A | 1990-09-18 | William R. Mahieu |
| Current interrupters for high voltage networks are disclosed which sever the post-zero arc plasma, connecting a pair of arc terminating electrodes, near an upstream wall electrode and displace the severed plasma with a high dielectric strength gas, gaining dielectric strength faster than the transient network voltage recovers across the lengthening plasma discontinuity. Use of a high enthalpy dielectric displacement gas, created at the time of load or fault current interruption, makes plasma severing and displacement possible. High enthalpy displacement gas mixtures are preferably produced by combustion of solid propellants and/or ablation of solids rich in hydrogen. | ||||||
| 295 | Apparatus for protecting electrically operated devices | US179188 | 1988-04-08 | US4910627A | 1990-03-20 | Gotthardt C. Mahlich |
| Apparatus for protecting electrically operated devices from damage as a result of penetration of moisture has an electric switch or a normally intact conductor, and an explosive or ignitable actuator which initiates an opening or closing of the switch or at least partial destruction of the conductor when operated by one or more sensors which detect the presence of moisture in or close to the electrically operated device. The explosive actuator can be used to clear the path for movement of a movable switch contact from open to closed position or vice versa, or to break up a conductor when ignited or otherwise operated in response to a signal from the moisture sensor or sensors. A combustible actuator can employ a flash light whose envelope confines a portion of a conductor and further contains a combustible material serving to generate heat on ignition in response to a signal from the sensor or sensors whereby the heat destroys the integrity of the portion of the conductor in the envelope. | ||||||
| 296 | Electronic sectionalizer and mounting structure for switchgear | US110966 | 1987-10-20 | US4797777A | 1989-01-10 | Lloyd R. Beard |
| An electronic sectionalizer mechanism includes upper and lower contact mounting structure, and a sectionalizer tube carrying a logic circuit is telescopically received within the lower contact mounting structure. Once fault current conditions downstream of the sectionalizer mechanism are detected by the logic circuit, an actuator is fired and the tube drops in a longitudinal, non-lateral motion toward an isolated or open circuit position. In preferred embodiments of the invention, a pin of the actuator shifts along an axis parallel to the longitudinal axis of the tube so that immediate drop-out of the tube is assured. The sectionalizer mechanism requires comparatively little space for operating clearances and this is especially adapted for use on a retrofit basis within the confines of an existing subsurface or pad-mounted switchgear cabinet; additionally, the sectionalizer mechanism may also be installed in existing overhead mounting structure for cutouts. | ||||||
| 297 | Circuit interrupter having a chemical operator with double-acting drive means | US761452 | 1985-08-01 | US4686337A | 1987-08-11 | Ronald W. Crookston; Ivan T. Burney |
| A double-acting chemical operator drive assembly having a pair of pistons that are secured to the ends of a single piston rod and cooperate with a pair of power cylinders provide a positive drive for opening and closing the separable contacts of a circuit interrupter when the pistons are sequentially actuated by high-pressure gas generated by chemical propellant charges. The power cylinders are spaced apart and aligned with one another and the piston rod extends through open ends of the power cylinders. This eliminates the need for shaft seals and simplifies the manufacture and maintenance of the drive assembly. The operator drive assembly is coupled to the operating mechanism of the circuit interrupter by a yoke that is secured to an exposed medial part of the piston rod and then to a tie bar by a pair of drive rods. | ||||||
| 298 | Explosive-driven, high speed, arcless switch | US859164 | 1986-05-02 | US4680434A | 1987-07-14 | Phillip J. Skogmo; Tillman J. Tucker |
| An explosive-actuated, fast-acting arcless switch contains a highly conductive foil to carry high currents positioned adjacent a dielectric surface within a casing. At one side of the foil opposite the dielectric surface is an explosive which, when detonated, drives the conductive foil against the dielectric surface. A pattern of grooves in the dielectric surface ruptures the foil to establish a rupture path having a pattern corresponding to the pattern of the grooves. The impedance of the ruptured foil is greater than that of the original foil to divert high current to a load. Planar and cylindrical embodiments of the switch are disclosed. | ||||||
| 299 | Energy supplemented electrical fuse | US627494 | 1984-07-06 | US4677412A | 1987-06-30 | Dan Sibalis |
| An electrical fuse adaptable for a wide range of current rating and response times. The fuse comprises a conductive element and an explosive charge, the latter shearing the conductive element at a predetermined temperature. In the disclosed embodiments, the explosive charge can be heated to the detonation temperature using a variety of auxiliary heat sources. | ||||||
| 300 | Actuator for electrical circuit interrupter using nitrocellulose type solid propellant | US665021 | 1984-10-26 | US4641000A | 1987-02-03 | Ronald W. Crookston; Jeffry R. Meyer |
| An actuator for an electrical circuit interrupter has a power cylinder for operating the circuit interrupter from a high pressure gas flow provided by a gas generating power unit which is a shotgun type shell container filled with a propellant. The propellant is characterized as being composed of spherical nitrocellulose grains having a nitroglycerin content; it is essentially free of deterrent coating and may have a granulation of 0.038/0.020 inches diameter range. Two suitable types are WC 630 or WC 615 manufactured by Olin Corporation of East Alton, Ill. | ||||||
