摘要： An improved compressed-gas-type of circuit-interrupter is provided having a pair of separable contacts and a cooperating nozzle structure, through which the established arc is drawn. A spring-biased sleeve-valve surrounds at least one of these separable contacts, and extends at times into the orifice throat in the closed-circuit position of the device, and also during a portion of the opening operation, thereby blocking any gas flow through the throat of the orifice device in such blocking position of the sleeve-valve.The aforesaid sleeve-valve is preferably attached by a lost-motion mechanical connection with the associated captive contact, which it surrounds, so that during an intermediate portion of the opening operation, the sleeve-valve is physically picked up on the opening stroke by the aforesaid captive contact, or, alternatively, limited in its blocking action, and withdrawn out of the orifice throat upon take-up of the lost motion, thereby unblocking the said throat and thus permitting a flow of gas therethrough.

摘要： An improved puffer-type, compressed-gas, circuit-interrupter is provided having an improved separable contact structure with resilient stationary contact fingers biased inwardly upon the movable tubular venting arcing contact, the latter moving with a movable operating cylinder over a relatively-fixed piston structure, and carrying an insulating nozzle therewith. The movable tubular venting arcing contact is disposed upstream of the movable nozzle structure, and does not impede the gas flow through the nozzle structure, as generated by the relative movement of the operating cylinder over the relatively-fixed piston structure. Preferably, the relatively-stationary resilient contact fingers, are encircled by a tubular venting stationary contact support, being fixedly secured thereto, the arrangement functioning to cause contact interengagement between the stationary resilient contact fingers and the movable tubular arcing venting contact, so that upon circuit-interrupter opening movement, an arc is established between the forward tips of the resilient stationary contact fingers and the upper extremity of the movable tubular venting arcing contact. Double gas-flow occurs through both the stationary and movable tubular venting contacts, and yet the constricted portion of the insulating hollow movable nozzle may be increased only slightly by the relocation of the contact fingers to the stationary supporting portion of the interrupter. Additionally, the elimination of the usual upstream movable finger-cluster obstruction allows a corresponding reduction in the size and mass of the moving cylinder supporting spider.

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.The improved puffer-type interrupter of the present invention, additionally, is provided with a shorter insulating nozzle than in conventional "puffers" to provide a more efficient gas path; and finally, a continuous annular stationary piston configuration requires no orientation procedures for assembly operations.

摘要： An improved circuit-interrupter of either the vacuum-type, or of the compressed-gas type, is provided having a shunting capacitance around, or electrically paralleling, the separable power contacts of the main power interrupter. In series with the said electrically-shunting capacitance is capacitor-isolating disconnecting switch, which interrupts the residual capacitance current at a subsequent point in time following the interruption of the main-power current in the main-power interrupting unit.The present invention may be applied not only to vacuum interrupters, but also to compressed-gas circuit-interrupters of either the double-pressure gas type, or the single-pressure gas type, such as the so-called "puffer" gas type, creating gas flow by relative piston-and-cylinder operation.

摘要： A modular closing resistor assembly can be added in line with the interrupter assemblies of an extra high voltage circuit breaker and has a relatively short length. The resistor element consists of two stacks of disks which are disposed side by side and are electrically connected such that the alternate disks of each stack are connected in series with one another. The operating mechanism of the unit includes a linearly moving roller which engages a crank arm which is in turn pivotally connected to operate the movable closing resistor contact with a motion and with a variable mechanical advantage adapted to cause the resistor contacts to close at high speed just after the interrupter contacts close and to open after the interrupter contacts open.

摘要： The present invention relates to the utilization of a surge tank in the pneumatic line interconnecting the high-pressure reservoir with the pneumatic control valve controlling the operation of a driving, or operating piston reciprocally operable within a surrounding operating cylinder to operate a circuit-breaker. Preferably, the volume of the surge tank is roughly of the order of the piston-displacement volume traveled by the driving piston in its opening tripping movement of the circuit-breaker, when the mechanism is used to open the circuit-breaker. However, the mechanism may also be used, if desired, to effect closing of the circuit-breaker.Also, preferably, the inlet connection to the surge tank is somewhat restricted in diameter, so as to limit the gas volume exited from the main high-pressure reservoir, yet, however, nevertheless supplying a desirable biasing air pressure to counteract bouncing back, or return movement of the movable circuit-breaker parts at the end of the opening tripping operation of the associated circuit-breaker when the breaker contacts are fully open.

摘要： The invention provides a high performance circuit breaker with an independent pole operation linkage and conical composite bushings. A mechanical linkage for independently opening and closing a plurality of associated switches is provided by the invention. The linkage comprises a plurality of connecting rods that provide the initial driving force to open or close the switch, cranks for opening and closing the contacts of respective switches, linking elements which couple together the connecting rods and the cranks, and a number of lever assemblies having a bearing ring interfaced thereto. The bearing rings provide a supportive interface between two linking element but permit the linking elements to rotate independently from one another. The lever assemblies also provide an interface for the connecting rods and linking element. According to a method of the present invention, a connecting rod is actuated in response to a signal to cause the lever assembly to pivot. The linking rod interfaced with the connecting rod via the lever assembly is then rotated in response to the pivoting. A crank interfaced with the linking element is then pivoted in response to the rotation of the linking element thereby opening or closing a respective switch. The invention further provide a means and method for synchronously opening and closing the switches based on the current flowing into the switches. Preferably, conical composite bushings are provided in combination with the independent pole operation linkage in a high voltage circuit breaker according to the invention.
