Abstract:
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.
