Abstract

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 breaker-opening 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 dashpotting mechanism operating separately from the hydraulic actuating system is provided, thereby reducing flow restriction interference with breaker opening. 3 figs.

Hydraulically-actuated operating system for an electric circuit breaker

Patent Barkan, Philip (Media, PA); Imam, Imdad (Secane, PA)

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 formore »« less

Hydraulically-activated operating system for an electric circuit breaker

Patent Imam, Imdad (Secane, PA); Barkan, Philip (Stanford, CA)

This operating system comprises a fluid motor having a piston, a breaker-opening space at one side of the piston, and a breaker-closing space at its opposite side. An accumulator freely communicates with the breaker-opening space for supplying pressurized fluid thereto during a circuit-breaker opening operation. A normally-closed valve located on the breaker-closing-side of the piston is openable to release liquid from the breaker-closing space so that pressurized liquid in the breaker-opening space can drive the piston in an opening direction. Means is provided for restoring the valve to its closed position following the circuit-breaker opening operation. An impeded passage affordsmore »« less

400V class high-speed current limiting circuit breaker for electric power system

Journal Article Genji, Takamu; Nakamura, Osamu (Kansai Electric Power Co., Inc., Amagasaki (Japan). Technical Research Center); Isozaki, Masaru; ... - IEEE Transactions on Power Delivery (Institute of Electrical and Electronics Engineers); (United States)

In Japan, a new network distribution system with advanced protective and operational functions designed to meet the needs of today's information society is being studied. For this new distribution system, the authors have developed high-speed current limiting equipment using gate turn-off thyristors (GTOs), to lower the breaking capacity of switches and to suppress instantaneous voltage drops. The main components of this equipment are a high-speed vacuum switch and a GTO switch connected in parallel. The usual load current is carried by the vacuum switch. In case of a system fault, the fault current is commutated to and interrupted by themore »« less

Pulsed hydraulically-actuated fuel injector ignitor system

Patent Elliott, G.D.

This patent describes an electronically controlled fuel injector for an internal combustion engine having combustion chambers. It comprises an unthrottled air intake; first means for injecting the fuel into a given combustion chamber; second means for igniting the fuel before it enters the given combustion chamber, so that the fuel is burning as it enters the combustion chamber; and third means to electronically controlling the output power of the engine by electronically regulating the quantity of fuel injected during each injection of fuel into the given combustion chamber.
