摘要： An apparatus for operating a combined interrupter disconnect switch is disclosed. The disconnect switch is operated by a slow speed linear motion of a mechanism pullrod. The interrupter, which is a component of the disconnect switch arm, is operated by a high speed linear motion of the same mechanism pullrod. In a preferred embodiment, the apparatus of the present invention comprises: an operating rod; a high speed operating mechanism connected to the operating rod; a sliding gear having an elongated gear face; a motor, rotatably connected to the sliding gear; a coupling gear drive having a longitudinally disposed threaded shaft and an external gear face, connected to the operating rod and meshed with said sliding gear; a threaded rod threaded into the threaded shaft of the coupling gear drive; and a drive rod connected to the threaded rod and to the mechanism pullrod. The high speed operating mechanism and motor respectively provide high speed and slow speed linear motion to the mechanism pullrod. The elongated gear face of the sliding gear permits decoupling of the high speed operating mechanism and slow speed motor, although both are acting on the same mechanism pullrod. In a preferred embodiment, the operating mechanism of the present invention also comprises upper and lower limit switches, controlled by a switch control bracket, for transmitting open and close commands to the high speed operating mechanism and motor.

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： 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： An improved electromechanically-operated valve is provided having a main balanced piston-valve controlling an inlet port, and a cooperable relatively-movable valve-stem piston-assembly electrically actuated by a repulsion coil, for example, or a similar electrically-energizable coil, repelling an anvil, for example, secured to said valve-stem piston-assembly.Upon reduced voltage, the actuating coil has less energy, and is only able to effect opening movement of the valve-stem piston-assembly, which, upon its opening motion, opens, by valve action, an additional piston-surface area for a high-pressure region fed by a bypassing high-pressure gas-inlet port.

摘要： Power circuit breaker apparatus having a novel trip valve on the pneumatic operating mechanism for reducing air consumption of the pneumatic breaker operating mechanism. The novel trip valve includes the addition of a valve stem extension to the trip valve shaft disposed in a sliding fit with an exhaust port to the trip valve actuating cylinder which together provide for quick elimination of compressed air from the trip valve actuating cylinder at a predetermined time during the operation of the breaker mechanism. Positive positioning of the breaker contact and rapid closing of the trip valve at a predetermined time is effectuated thereby reducing air consumption while providing a fail-safe air cushion to the driving piston of the pneumatic mechanism to insure positive positioning of the breaker contacts.
