| 22 | Arc blow-out switch | US652973 | 1976-01-28 | US4053727A | 1977-10-11 | Karl Kriechbaum |
| A gas current blow-out switch has an electrically conducting compression cylinder, a stationary hollow power contact pin supported in the cylinder and a piston surrounding the pin and slidably received in the cylinder for compressing an arc-extinguishing gas therein. A nozzle is affixed to the cylinder for bounding one end thereof. A movable hollow power contact pin is supported coaxially with the stationary contact pin to assume open and closed positions. The switch has an electrically conducting stationary tube axially aligned with and spaced from the compression cylinder; a contact bridge slidably supported by and being in continuous electric contact with the stationary tube and the movable contact pin. The contact bridge has a closed position in which it electrically contacts the compression cylinder and an open position in which it is separated therefrom. An insulator cylinder which surrounds the compression cylinder and is slidable thereon, is coupled to the contact bridge for shifting the latter into its open position upon motion of the insulator cylinder in one direction. A carriage is shiftably arranged on a support and an externally actuated drive member is secured to the carriage and is displaceable between two limits with respect to the carriage. The drive member displaces the carriage after the drive member reaches either one of the limits. The drive member is arranged to displace the piston and the carriage is arranged to displace the insulator tube. | ||||||
| 23 | Method and apparatus for arc quenching | US491752 | 1974-07-25 | US3947649A | 1976-03-30 | Walter Hertz |
| An improved method for quenching an arc in an AC circuit breaker having an arc chamber in which the arc rotates in a quenching medium between open electrodes having ends close together in which the arc is caused to generate during its rotation, through a heating of the quenching medium, an over-pressure which is maintained beyond the zero crossing of the AC current with the gas flow produced by the over-pressure use for blasting the arc in the nozzle. Various embodiments for use in medium and high voltage switching installations which permit the switching of large currents with a simple and inexpensive arrangement are illustrated. | ||||||

| 30 | Gas-driven power switch with power-assisted piston | US927475 | 1992-11-25 | US5285036A | 1994-02-08 | Dieter Lorenz |
| A gas-blast circuit-breaker having an actuated compression cylinder may include a reinforced actuation of the compression piston through the magnetic effect of the breaking current. A hollow-cylindrical body of ferromagnetic material concentrically surrounds a stationary contact member and is rigidly coupled to the compression cylinder. The hollow-cylindrical body has at least one slot in which a piston rod of the compression piston is guided. One section of the piston rod consists of ferromagnetic material. As soon as a small portion of this section enters into the slot, it is pulled into the slot by the magnetic effect of the breaking current. As a result, the compression piston is accelerated in a direction opposite the movement of the compression cylinder. Thus, the maximum quenching gas pressure is reached sooner than it would have been with a sole actuation of the compression cylinder. The gas-blast circuit breaker is intended to be used as a puffer circuit-breaker, in particular an SF.sub.6 circuit-breaker. | ||||||
| 31 | High-or medium-tension compressed-gas circuit breaker taking circuit-breaking energy from the arc | US222641 | 1988-07-21 | US4880946A | 1989-11-14 | Edmond Thuries; Denis Dufournet; Michel Perret |
| A high- or medium-tension compressed gas circuit breaker taking circuit-breaking energy from the arc, the circuit breaker being of the type comprising:a fixed assembly including main contacts (8a) and arc contacts (21a);a moving assembly including main contacts (26) and arc contacts (25);a blast volume (VI) including a piston (12) which moves on contact separation and urges compressed gas through a blast nozzle (7) which opens over the zone where a main arc forms when the arc contacts separate, anda set of auxiliary contacts (22a, 21c) in series with the arc contacts for creating an auxiliary arc in the volume (V2) situated behind the piston,the circuit breaker further including means (23, 24) for allowing the auxiliary contacts to separate only when the pressure in the blast zone reaches a predetermined threshold. | ||||||
| 32 | Puffer-type gas-blast circuit-breaker | US588174 | 1984-03-12 | US4553004A | 1985-11-12 | Edmond Thuries |
| The circuit breaker has linear displacement moving contacts (3, 4) coupled to a fixed cylinder blast assembly (6) having two concentric pistons (7, 8). The first piston (7) is fixed to the moving contact equipment and is actuated by the circuit breaker control mechanism. The second piston (8) is free and is driven by electrodynamic energy from the current being interrupted. A spring (23) urges the second piston (8) towards the top (16) of the cylinder. Coupling means (30) which lock the second piston (8) when it reaches the top of the cylinder are released by the first piston (7) when it leaves the vicinity of the top (16) of the cylinder. It only requires small operating energy while enabling small intensity and large intensity currents to be interrupted by matching itself thereto. | ||||||
| 33 | Axial blast puffer interrupter with multiple puffer chambers | US731421 | 1976-10-12 | US4219711A | 1980-08-26 | Lorne D. McConnell |
| A puffer interrupter has two axially spaced movable pistons fixed to the movable contact. A fixed barrier is disposed between the two pistons and a further fixed barrier is positioned at the end of the cylinder chamber. The two fixed barriers form three variable volume chambers with the two movable pistons. As the interrupter is opened, the central chamber formed between the end movable piston and fixed barrier between the two pistons reduces in volume to generate an increasing pressure while the two volumes on either side of the central volume increase in volume to produce a decrease in pressure. Gas then flows axially through the separating contact from the decreased volume central chamber to the outer reduced-pressure chambers. An auxiliary piston is formed within the central chamber and can increase the central chamber volume when the pressure within the central chamber exceeds a given value due to blockage of the nozzle by high arc-generated pressures. | ||||||
| 34 | Contact opening means for a circuit breaker | US27533272 | 1972-07-26 | US3867597A | 1975-02-18 | JAWELAK MELBOURNE G; BONI RICHARD R |
| An auxiliary kickoff contact opening means is provided which supplements the main contact opening means during the inital opening movement of the circuit breaker contacts. The initial kickoff force is provided by a spring and control means is included which comprises a piston engaging the spring and a fluid connection to the interior of a main contact structure and an interrupting chamber. During initial opening movement of a main movable contact, gas pressure generated by an arc between the main contacts is applied via the fluid connection against the piston to thereby apply force to the spring in a direction opposite to its opening force. If sufficient gas pressure is generated, the opening force of the spring will be retarded. If the gas pressure is excessive, the piston and spring will be moved in a direction opposite to the opening movement and the initial opening force of the spring will be completely nullified.
