摘要： A minimum liquid circuit interrupter provides a relatively remote cooled storage unit for the dielectric liquid and fills a cylinder which is in close proximity to the insulating nozzle of the interrupter, the cylinder being driven at one end by a piston and closed at the other by the moving contact of the interrupter.

摘要： An improved puffer-type gas-blast circuit-interrupter is provided having a movable operating cylinder assembly movable over a relatively-fixed piston structure. A high compression ratio is obtained during the opening operation by minimizing the "dead" volume of arc-quenching gas within the movable operating cylinder, and an efficient gas-flow path through the movable cylinder assembly smoothly converges through the movable nozzle throat-area into the drawn arc. A high electrical withstand capability is accomplished by using a generous radius on the lower ends of external stationary main contact fingers, and by shrouding, or shielding the stationary contact probe within the surrounding shield of the stationary contact fingers. The circuit-interrupter of the present invention is adapted for various current ratings, such as 2,000 amperes, 3,000 amperes, or 4,000 amperes, for example, by varying the number of stationary main contact fingers used surrounding the movable operating gas-cylinder. High-interrupting performance is obtained with a reduced residual gas volume at the end of the opening stroke, and, consequently, a higher gas-compression ratio is obtained. The gas-flow downstream of the nozzle throat area is confined within the cluster of stationary main contact fingers, and this cools the ejected gas to prevent voltage breakdown to electrical members at another potential. Open venting ports are provided at the upper end of the stationary contact finger cluster to prevent stagnation of the hot arced gas flowing into the stationary contact finger cluster, which thereby permits the hot arcing gases to be blown out of the way to insure good interrupting performance and a high breakdown value.

摘要： A multi-pole high-power circuit-interrupter is provided having a single common operating mechanism therefor, and having independent pole tripping operation by associating with at least one of a plurality of the pole-units its independent ball latching means, which may be very quickly mechanically released upon a tripping operation associated with the respective one pole-unit to which said ball latching device is connected.Another important feature of the invention is the provision of a plurality of load-release latching balls, which may be quickly released from their latched position by a pneumatic releasing device, which is energized in response to electrical overload conditions existing in the respective pole-unit to provide thereby a tripping operation for the particular pole-unit, to which the ball-latching releaseable device is mechanically connected.Still another feature of the present invention is the provision of a spring-return catch-member in a ball-latch releasing device, which holds the load-release balls in their latched position, and provides a desirable quick relatching operation at the end of the closing operation of the circuit-interrupter.

摘要： An improved closing resistor support is provided for the closing resistances of high-voltage high-power compressed-gas circuit-interrupters in which the formerly-used insulating straps are completely eliminated, and consequently the voltage conditions are thereby improved to thus withstand a much higher-voltage breakdown capability during the closing operation.A metallic ring is preferably utilized at the front end of the circular closing resistance assemblage and provides a uniform compression of the individual resistor coils and, additionally, provides a desirable electrical field condition at the resistor assemblage.

摘要： A high-voltage gas-type circuit-interrupter is provided utilizing a pair of serially-related puffer-type circuit-interrupters mechanically connected together, and operated by a single common operating rod. The stationary contact structures may be supported by rods attached to the interrupter support plate, or, alternatively, by a pair of terminal-bushings extending downwardly interiorly within a surrounding metallic tank at ground potential, for example.The operating arrangement may be such as to involve a linearly movable generally vertically extending common operating rod actuated externally of the grounded gas-filled tank by a suitable operating mechanism.Preferably, the individual puffer-type gas interrupters each involves the linear-slidable operation of a movable operating gas-compression cylinder, carrying the movable contact structure and an insulating nozzle orifice movable over a relatively stationary fixed piston structure.
