摘要： A unique, energy efficient puffer interrupter having a puffer piston and an opposed floating piston or head is described in detail. In one embodiment, the puffer interrupter is formed from a pair of electrical contacts which are disposed within a chamber filled with an arc extinguishing fluid. A prime mover or switching means is used to open and close the switch by moving one of the contacts with respect to the other. A puffer piston is disposed at one end of a cylinder surrounding the fixed contact. A floating piston is disposed at the opposite end of the cylinder and biased towards the moving contact assembly and away from the puffer piston. The puffer piston and the floating piston and the cylinder define a pressurization chamber, which is in fluid communication with the gap defined by the switch contacts. A pressurizing valve means controls the flow of gas from between the two pistons and into the gap thereformed when the switch is opened. A time sequencing means opens the switch contacts after sufficient pressure has been developed to extinguish the arc formed between the contacts. Another sequencing means controls the movement of the floating piston so as to minimize the peak pressure formed in the volume between the two pistons as the contacts are opened and the arc is extinguished. By minimizing the pressure overshoot and by moderating the pressure to a more constant value, the power required to operate the device is consumed more uniformly over that of one having only one moving piston.

摘要： A puffer interrupter with arc energy assist employs a cylinder which moves telescopically over a stationary piston. The cylinder carries a movable contact structure and an insulation nozzle and moves within an insulation chamber. The cylinder has an extending flange slidably sealed to the interior of the housing. The flange has a surface which faces the gas volume which is expanded during arc current interruption so that a force is applied to the cylinder which adds to the force of an operating mechanism connected to the cylinder in order to operate the interrupter to its open position.

摘要： A center shaft of a swing lever, connected to a moving contact of a main interrupting unit, is supported by hollow bearings. The center shaft is provided with an engaging portion which is positioned in the hollow space of the hollow bearing and therein connected to a rotating shaft of which the force is partially exerted on a moving contact of a closing resistor device. Therefore, if the gas circuit breaker does not need the closing resistor device, the rotating shaft may be removed. For the gas circuit breaker requiring the closing resistor device, the rotating shaft may be inserted into the hollow bearings. For both cases, the gas circuit breaker is thus able to take the same fundamental construction.

摘要： A puffer type circuit breaker is provided with a pump means consisting of a piston and a cylinder for producing a blast of arc-extinguishing gas. The piston is joined to one contact of the circuit breaker and the cylinder to the other contact. Both contacts are connected to an operating device which is adapted, during the first part of a breaking operation, to move the contacts in opposite directions away from each other, whereupon one contact and the piston joined thereto are returned to the initial position.

摘要： A high voltage, high power circuit interrupter uses liquid SF.sub.6 in a puffer type arrangement. The cooperating contacts are surrounded by a nozzle and an upstream and a downstream piston, which are moved by a constant force-operating mechanism, move liquid SF.sub.6 between the cooperating contacts when they separate, in order to interrupt the arc between the contacts. The interrupter requires a relatively low volume of SF.sub.6 and a constant pressure is generated in the liquid during interruption. The interrupter ratings are adjusted by varying the differential pressure across the nozzle, and by changing the base-operating pressure.

摘要： A blasting piston ("puffer") circuit breaker having two stationary nozzle-shaped contacts which are bridged in the "on" position by a hollow, cylindrical, movable contact and an annular body of insulating material for reducing the cross-section of the oncoming flow between the stationary contacts during the course of the switching-off motion. The annular body has an axial dimension smaller than the length of the gap between the stationary contacts and is placed approximately in the middle between the bottom of the cylinder and the free end of the movable contact.

摘要： An electrical circuit breaker of the gas blast type comprises a pair of contact members disposed within an arc quenching zone of a chambered part at which separation of the contact members takes place and an arc is established therebetween. An annular blast gas in-flow duct surrounds the arc quenching zone and through which the gas is forced by piston action in the direction of the quenching zone at the time of contact separation, and the discharge end of this in-flow duct includes a gas deflection zone for preventing blow-back of hot arc extinction gases formed in the quenching zone through the in-flow duct in the opposite direction thereby minimizing the chances of damage to the piston system.

摘要： A puffer circuit interrupter is taught. Arc extinguishing gas is vented through a hollow stationary arc contact into a gas condenser. The gas condenser is an elongated toroid having a well-defined open central region. The gas condensing portion of the toroid is formed from overlapping layers of wound copper mesh. The elongated central opening of the toroid is aligned with the hollow electrode for receiving the arc quenching gas. At one end of the condenser is an external conductor for the puffer circuit interrupter. At the other end of the condenser is a disc having a central opening therein through which the hollow electrode protrudes. The condenser is thus firmly maintained longitudinally between the disc and the external electrode. Surrounding the circumferential periphery of the condenser and bridging the space between the disc and the electrode are longitudinally disposed circumferentially spaced fingers. The spaced fingers form a support cage for the condenser. Furthermore, the fingers extend longitudinally beyond the disc for making electrical contact with a movable contact in the circuit breaker apparatus. These fingers thus act as the rated current carrying conductors when the circuit breaker apparatus is in the closed state.
