    Abstract: The chamber has a contact arrangement (2) held in a housing. The housing includes two hollow bodies (7, 8) maintained at high voltage, and an insulating pipe (6) held at a distance to the bodies. The bodies include an upper surface formed with electrically shielded separation zones (71, 72, 81, 82), during operation of the interrupter. The separation zones separate two upper surface zones of different roughness in the hollow bodies.

    IPC: H01H33/70

    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.

    IPC: H01H33/70

    Abstract: The switch has an axis (A) by which an axial coordinate (z) which runs parallel to the axis and a radial coordinate (r) which extends perpendicular to it are defined. An arcing contact piece (1), a current conducting element (2), and an arc-resistant element (3a) are provided. The arcing contact piece (1) has a hole (6) for directing an axial flow (4) of a gas (4) that is heated by an arc (5) which is based on the arcing contact piece (1) if applicable. The arcing contact piece (1) forms a planar contact (F) along with the current conducting element (2) in order to conduct a fault current (I) that flows through the arcing contact piece (1) and the current conducting element (2) during the time the arc (5) burns. The current conducting element (2) is shielded from the flow (4) near the planar contact (F) with the aid of the arc-resistant element (3a). The current conducting element (2) has an axial area (2a) in which a radial inner dimension (d2) of the current conducting element increases step by step or continuously as the distance from the planar contact (F) increases parallel to the axis (A). The axial area (2a) accommodates the arc-resistant element (3a).

    Abstract: A screwed connection with a radially sliding stop is arranged in the edge region of one of the following: the insulation nozzle, the cylinder base (17), a first mounting flange for fastening the piston on the switching chamber housing, or a second mounting flange for fastening a reversing drive connected to the second arc contact. This connection fixes the insulation nozzle , cylinder base (17), first or second mounting flange, by partial spreading and clamping in one of both conductor tubes (8) or in the switching chamber housing.
