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.
