摘要： An interrupter unit for a circuit breaker includes a gas-insulated housing, which is fillable with a quenching gas, and a gas-guiding structure, which is disposed in the housing and has a guide tube and at least one diverting element. The guide tube extends in tubular manner about a longitudinal axis of the interrupter unit in order to guide hot gas, which is created in an electric arc region of the interrupter unit by the heating of quenching gas by an electric arc, away from the electric arc region. The at least one diverting element is configured to set hot gas exiting from the guide tube in a circular flow running around the longitudinal axis.

摘要： A medium or high-voltage circuit breaker is provided. An arc-extinguishing fluid is stored in a pressure chamber, which is made up by an arcing chamber of the circuit breaker where an electrical arc is extinguished. No tubings or other conduction devices for pressurized fluids are necessary during current interruption. This speeds up contact separation and arc extinguishing. In a first, closed position of the circuit breaker, the pressure chamber is delimited by a sealing wall which is fixed to a movable first arcing contact. The sealing wall acts as a valve and as a piston at the same time, because it opens the outflow of pressurized arc extinguishing fluid and it concurrently actuates arcing contact separation. The arcing chamber enables the stored pressurized arc extinguishing fluid to perform fast contact separation within a few milliseconds and extinguishing a gaseous arc on the same timescale.
摘要翻译：提供中压或高压断路器。灭弧流体存储在压力室中，压力室由断路器的电弧室组成，其中电弧熄灭。在电流中断期间，不需要用于加压流体的管道或其他传导装置。这加快了接触分离和灭弧。在断路器的第一个闭合位置，压力室由固定到可移动的第一电弧触点的密封壁界定。密封壁同时用作阀门和活塞，因为它打开加压灭弧液体的流出并同时致动电弧触点分离。电弧室使得储存的加压消弧液在几毫秒内执行快速接触分离，并在同一时间尺度上熄灭气态电弧。
