Abstract: Devices, systems, and methods are provided for a high voltage switch. The device can include a first housing, a switch, and a polymer insulating material. The housing can be at ground potential. The switch can be located within the housing and can include a current-breaking component and a moving contact. The current-breaking component can include a fixed contact and an opening contact. The fixed contact can be coupled to a first power lead. The opening contact can be configured to receive a moving contact. The moving contact can be coupled to a second power lead and can be controlled by an actuating mechanism.

Abstract: A novel electric power interrupter is provided, the interrupter comprising concentric springs and interlocking hooks for opening and closing the interrupter. The electric power interrupter further comprises a housing over a vacuum chamber and an electrically insulating layer around the vacuum chamber, a fixed section and a moving section. The butt contact of the fixed section is stationary, while the butt contact of the movable section moves towards and away from the fixed section. A toggle mechanism is provided for operating the movable section to open or close the interrupter. The present invention provides a better voltage dissipation and reduces the risk of electrical arcs forming outside the interrupter.

Abstract: A fluid flow and cooling system and method are provided. The system has a substantially cylindrical tube shape and is configured to be installed in a circuit breaker for allowing the flow of fluids while dissipating heat from said fluids. The system comprises a plurality of openings on each of front and back surfaces, the openings of the front surface being connected to the openings of the back surface by a plurality of side passages. By having a plurality of side passages for the flow of fluids, heat dissipation may be improved compared to previous circuit breakers tubes for dispensing arc quenching fluid. The method cools a fluid flowing in a cooling device having side passages.

Abstract: The present invention concerns a gas insulated circuit breaker system. The system comprises a base station, an insulating column, a transition elbow and an interrupting chamber. With the placement of motion transferring mechanisms in the base station and the transition elbow, the system allows the opening and closing of the integrated circuit breaker within the interrupting chamber in a compact and efficient configuration from a link to an external control module in the base station.

Abstract: A sealed solenoid, magnetically operated electric power switch is suitable for use as capacitor, line and load switch operating at transmission and distribution voltages that includes no dynamically moving seals through the sealed container housing the contactor portion of the switch. The sealed solenoid switch includes a magnetically operated drive system with an actuator that magnetically couples across the container wall to avoid the use of a moving or sliding seal as part of the drive system. The sealed solenoid switch may also include a ballast resistor and resistor contact located inside the sealed container to avoid another seal as part of the ballast system. A magnetic latch holds the switch in a closed position, and a spring holds the switch in the closed position, to avoid the need for an energizing current to maintain the switch in either position.

Abstract: An electric power switch suitable for use as a capacitor switch that includes a drive unit having a bi-directional toggle mechanism and linearly opposing opening and closing spring latches. The opening and closing spring latches are located on opposing sides of the toggle mechanism, which includes an open-cage spring mechanism with coaxial, nested opening and closing springs operated by a rotating, motor-driven charging cam. To open the circuit interrupter, the opening spring latch is tripped to release the opening spring and thereby remove the capacitor bank from the electric power circuit. To introduce the capacitor bank into the electric power circuit, the motor rotates the charging cam through one complete rotation, which charges the opening and closing springs and trips the closing spring latch to release the closing spring to close the circuit interrupter and thereby introduce the capacitor bank into the electric power circuit.

Abstract: An electric power interrupter with an internal contactor that is suitable for use as a line and load switch constructed from light weight materials including a fiberglass or composite insulator and aluminum flanges. The light weight design feature allows the power interrupter to be supported above a standard disconnect switch insulator without having to replace or reinforce the insulator. The power interrupter also includes a latch mechanism with a low-force trip action, such as a spring-driven toggle mechanism that accelerates the internal contactor to break the electric power circuit on the opening stroke. This low-force trip action allows the power interrupter to be actuated by a standard disconnect switch operating mechanism without having to upgrade or augment the standard operating mechanism. For these reasons, the power interrupter may be installed as a retrofit upgrade to an existing standard disconnect switch without having to modify the underlying disconnect switch.

Abstract: A capacitor switch including a power contactor and an impedance contactor located within a relatively slender container filled with dielectric gas. The container may be a “dead tank” or an insulator. For the insulator configuration, the switch also includes a conductive cap housing a charging impedance located on the end of the insulator. The power contactor includes a relatively fixed probe contact and a linearly moving socket. The impedance contactor is ring-type butt contactor surrounding the penetrating contactor that includes a retracting (but otherwise fixed) contact that surrounds the fixed probe, and a traveling ring contact that surrounds and moves with the moving socket contact. The impedance contactor closes before the power contactor on the closing stroke to introduce the charging impedance into the circuit. A puffer mechanism retards the expansion of the retracting contact on the opening stroke, which causes the impedance contactor to open before the power contactor.

Abstract: A pivoting electrical connected useable in a molded case circuit breaker including a pair of contact plates for contacting the circular contact member of a contact carrying arm. The pivoting electrical connection provides at least three contact locations between the contact plates and the circular contact member. The contact locations provide current paths between a first terminal coupled to the contact plates and an electrical contact fixed to the contact carrying arm. The pivoting electrical connection allows the contact on the arm and an electrical contact coupled to a second terminal to be opened and closed.
