摘要： An exemplary high voltage circuit breaker includes an interruption chamber that is filled with an extinguishing agent. The interruption chamber having at least two separable arcing contact pieces that are coaxially arranged and an arcing zone in which an electric arc is producible during an interruption process. The interruption chamber includes at least two inlets and at least one outlet located in between the two inlets. The inlets and the at least one outlet are connected with the arcing zone such that the electric arc is extinguishable in at least three arc interruption zones by means of extinguishing flows streaming out of the at least two inlets into the arcing zone upon pressurization and introduction of a portion of the extinguishing agent in the arcing zone, and leading an amount of the extinguishing flows through the outlet out of the arcing zone.

摘要： A conductor arrangement is provided for reducing very fast transients in high voltage applications. The conductor arrangement includes a conductor element having a main conducting orientation, and a conductive annular shell element coaxial to the conductor element, thus forming an annular cavity around the conductor element. The annular shell element in the main conducting orientation includes a first end portion and a second end portion. The first end portion is conductively connected to the conductor element. The second end portion includes an annular collar which is substantially coaxial to the conductor element, thus together with the conductor element forming a coaxial capacitor which has a solid material filling. The capacitor includes a surge arrester which may serve as an energy conversion portion.

摘要： A high-voltage circuit breaker includes two arcing contacts, which are capable of moving relative to one another along an axis, an insulating nozzle, a heating volume for accommodating quenching gas, a heating channel, and an overpressure valve. The pressure of the quenching gas is based on the energy of a switching arc, which is formed when the breaker opens and generates arcing gas, and the heating channel opens out, with axial alignment, into the heating volume. The heating channel connects an arc zone, and the overpressure valve limits the pressure of the quenching gas by opening a relief duct, which opens out into an expansion space. In high-current switching, the pressure of the arcing gases in the arc zone is limited, and the quality of the quenching gas stored in the heating volume is improved, due to the relief duct having an outflow section extending in the radial direction.
