    Abstract: PROBLEM TO BE SOLVED: To provide a circuit breaker that not only has an increased current transfer ability but also improves a contact formed by a rated current contactor when a switch is closed and opened. SOLUTION: Two contact mechanisms capable of being moved along an axis A, in the lengthwise direction of the switch form an arc contactor system 12 and a rated current contactor system 9 connected electrically in parallel thereto; here, one of the contact mechanisms has the rated current contactor system 9, an inner rated current contactor 6 and an outer rated current contactor 7; and the inner rated current contactor 6 extends over the outer rated current contactor 7 in the lengthwise direction axis A and the outer rated current contactor 7 surrounds the inner rated current contactor 6 in a coaxial form.

    Abstract: PROBLEM TO BE SOLVED: To provide a puffer circuit breaker with a valve for releasing overpressure in a puffer volume.
    SOLUTION: The circuit breaker includes a puffer volume 9, and at least one overpressure valve 16 for discharging gas from the puffer volume 9 if the pressure therein exceeds a given threshold. The overpressure valve 16 comprises a piston 17 and a spring 19 as well as a cavity 18 in a stationary support body of a movable contact assembly 2. The overpressure valve 16 is designed into compact and simple structure and has low hysteresis and large cross-section.

    Abstract: A seal (1) protects a hot-gas/gas-pressure-sensitive element (10) from a flow (8) of hot gas and has a means (2a) of generating a sectional flow so as to create a sectional flow (8a) of hot gas in the flow of hot gas. Downstream to this, a channel (2) reduces mass flow rate in the sectional flow. A means (3) of expansion expands the sectional flow according to volume. An independent claim is also included for a method for protecting a hot-gas/gas-pressure-sensitive element in a heavy-duty circuit breaker from a flow of hot gas.

    Abstract: The disclosure relates to an electrical switching device, e.g., a generator circuit breaker, and to a method for improved switching-gas cooling. Gas jets are formed by a nozzle body in the exhaust area, are directed against a baffle wall and are swirled. The baffle wall is a component of the switching chamber enclosure and has a high thermal capacity and/or thermal conductivity, so that the switching gas vortices produce a highly efficient switching gas cooling on the baffle wall by turbulent convection. Exemplary embodiments relate inter alia to the design of the baffle wall and of the nozzle body. Advantages include: protection of the switching chamber enclosure against hot gases, improved switching gas cooling, and increased breaking capacity.
