摘要： This hydraulically-actuated operating system comprises a cylinder, a piston movable therein in an opening direction to open a circuit breaker, and an accumulator for supplying pressurized liquid to a piston-actuating space within the cylinder. A normally-closed valve between the accumulator and the actuating space is openable to allow pressurized liquid from the accumulator to flow through the valve into the actuating space to drive the piston in an opening direction. A vent is located hydraulically between the actuating space and the valve for affording communication between said actuating space and a low pressure region.Flow control means is provided for restricting leakage through said vent to a rate that prevents said leakage from substantially detracting from the development of pressure within said actuatng space during the period from initial opening of the valve to the time when said piston has moved through most of its opening stroke. Following such period and while the valve is still open, said flow control means allows effective leakage through said vent. The accumulator has a limited capacity that results in the pressure within said actuating space decaying promptly to a low value as a result of effective leakage through said vent after the piston has moved through a circuit-breaker opening stroke and while the valve is in its open state. Means is provided for resetting the valve to its closed state in response to said pressure decay in the actuating space.

摘要： A switch or circuit breaker that provides a high contact pressure when closed and provides a reduced and automatically regulated contact pressure during opening and closing. In one embodiment a pair of contacts is mounted opposite one another and one of the contacts is carried at one end of a pivotably mounted lever so that it can move towards and away from the other by a movement of the other end of the lever. A fluid operated cylinder arrangement is provided to move the switch blade from a first disengaged position to a second engaged position between the blades. The cylinder is mounted on a mechanical linkage so that the linkage is deflected in accordance with the resistance of the blade to movement, and the deflection of the linkage moves the lever tending to decrease contact pressure. A balance is reached between contact pressure and the blade movement tending to maintain a constant and reduced contact pressure during opening and closing.

摘要： Pressurized operating fluid, such as oil for hydrostatic fluid bearings, is directed into a chamber against a plunger urging the plunger into a first position. A monitoring pressure force slightly less than the force of the operating fluid when the operating fluid is at a minimum working pressure is exerted against the plunger tending to move the plunger from this first to a second position. Thus, when the pressure of the operating fluid drops below the minimum working pressure, the plunger is moved to its second position and such movement is sensed, thereby sensing the malfunction.

The fluid introducing valve means includes a fluid introducing valve disposed in the proximity of the operating piston and adapted to move toward the operating piston when brought to an open position, with its back being exposed to the operating medium at all times. By this arrangement, the device is capable of operating the circuit breaker at high speed even if the circuit breaker is under a high load and it has a large contact parting distance.

摘要： A fluid actuating device for an electric switching apparatus such as a high-voltage power circuit breaker or the like includes an actuator for actuating the electric switching apparatus. The actuator has an actuator cylinder and a differential piston movable in the cylinder between first and second end-positions corresponding to the open and closed positions respectively of the switching apparatus. The differential piston has two endfaces for receiving fluid pressure force. One of the end-faces has a surface area greater than the other end-face thereof. A reservoir supplies fluid under high pressure to the two end-faces of the piston. A valve is provided for alternately interrupting and passing the fluid from reservoir to the larger area end-face whereby the piston is caused to move from the second end-position to the first end-position when the valve interrupts fluid to the larger area end-face. An opening formed in the actuator cylinder conducts fluid to and from the variable volume chamber conjointly defined by the larger end-face and the cylinder. A damping arrangement reduces the speed of the piston in the course of the movement of the same toward the first end-position and before the first end-position is reached. The damping arrangement includes an ancillary piston projecting from the larger area end-face of the differential piston which is received in the opening for interrupting the flow of fluid passing therethrough from the chamber before the piston reaches the first end-position. This action causes the fluid remaining in the chamber to be conducted away through a bypass whereby the speed of the differential piston is reduced. A second bypass is connected in parallel with the first-mentioned bypass and the valve includes means for controlling the passage of fluid through the second bypass to get fluid to the larger area end-face while the ancillary piston is still in the opening during the first part of a movement of the differential piston to the second end-position from the first end-position.

摘要： A metal-clad, high-voltage switchgear assembly is disclosed for an electrical conductor wherein the rotational symmetry of the electric field of the conductor is maintained. The switchgear assembly has a metal enclosure containing the conductor arranged to extend along the axis of the enclosure. The conductor is supported with respect to the enclosure by disc-shaped insulators that partition the enclosure into fluid-tight compartments separated from each other. A disconnect switch is arranged at a gap in the line of the conductor , the gap being defined by mutually adjacent end portions of the conductor. The switch includes a cylinder formed in one of the end portions of the conductor so as to define a cylinder chamber that communicates with the compartments. A piston switching member is slideably mounted in the cylinder and moves to mutually connect and disconnect the end portions of the conductor in response to changes in fluid pressure in the compartments.

摘要： A tank type gas-filled circuit breaker has interrupting contacts contained in a pressurized insulating gas filled chamber provided within a tank which in itself forms a low-pressure gas chamber the circuit breaker includes, an operating rod of insulating material penetrating through the tank wall and the high pressure chamber and coupled to the interrupting contacts, a driving means for the operating rod including a piston operating in a cylinder disposed outside of the tank valve, means for sealing highpressure gas, e.g., air, in a chamber formed at one side of the piston in the cylinder and means for creating an impulsive driving force for operating the valve means, whereby when the impulsive force acts to release the sealing of the valve means, the high-pressure gas is instantaneously introduced into the chamber at one side of the piston, and the insulating rod is operated by the piston to separate the contacts of the circuit breaker. The valve means per se may be operated by means using electromagnetic attractive or repulsion forces, or alternatively by an impulse caused by igniting an explosive agent.

摘要： A pressure operated electric switch having two sets of contacts operated at different pressures acting on the switch, comprises a helical conductor in permanent contact with a first fixed contact and normally held out of engagement with a second and a third fixed contact by a plunger which is responsive to the operating fluid pressure. Movement of the plunger following a suitable reduction in the operating fluid pressure first brings the helical conductor into engagement with the second fixed contact and subsequently with the third fixed contact. The plunger may be arranged to disengage from the helical conductor when the latter is engaged with both the second and the third fixed contacts, or the plunger may be arranged to make part of the circuit between the first and second fixed contacts.
