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.

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.
