摘要： The heavy-duty circuit-breaker having an axis (A), and having an arcing contact piece, a current-carrying element and an erosion protection element, with the arcing contact piece having an opening in order to carry an essentially axial flow of a gas which has been heated by an arc, and together with the current-carrying element forms a flat contact (F) in order to carry a short-circuit current (I) which flows through the arcing contact piece and the current-carrying element, and with the erosion protection element essentially shielding the current-carrying element from the flow close to the flat contact (F), is characterized in that the current-carrying element has an axial area in which a radial internal dimension (d2) of the current-carrying element increases in steps or continuously as the distance from the flat contact (F), measured parallel to the axis (A), increases.

摘要： The heavy-duty circuit-breaker with arc blowing has an element which is sensitive to hot gas and/or to gas pressure and is protected by means of a seal against a hot-gas flow. The seal is advantageously a movable non-contacting seal. The seal has a channel entrance for production of a partial hot-gas flow of the hot-gas flow and, connected downstream from this, a channel in order to reduce the mass flow of the partial hot-gas flow, and an expansion chamber in order to expand the volume of the partial hot-gas flow. The expansion chamber is a pressure-relief area. The element may, for example, be a guide element, a contact-making element or a sealing element.

摘要： The switching chamber is intended for a gas-insulated high-voltage circuit breaker. It contains an axially symmetrical housing and a contact arrangement held in the housing with two switching pieces, of which at least one is arranged such that it can move along the housing axis. The switching chamber housing has two hollow bodies consisting of electrically conductive material which can be connected to a high voltage and an insulating tube holding the hollow bodies axially at a distance. A separation zone, which is electrically shielded during operation of the circuit breaker, is formed in the surface of at least one of the two hollow bodies and separates two surface zones having different degrees of roughness from one another in the hollow body. In homogeneities in the surface of the switching chamber housing which may reduce the dielectric strength of the circuit breaker equipped with the switching chamber therefore do not have any effect. For this reason, the switching chamber and the circuit breaker are characterized by a high degree of operational reliability and safety with a simple design.

摘要： The sheet-metal casing comprises at least two sheet-metal parts (1, 2) and has a plastic seal (9) arranged in between. A first sheet-metal part (1) is folded over along the seal (9) to form a fold (10) and comes into contact with the second part (2) in such a way that, in addition to the fold (10), a gap (13) for accommodating the seal (9) forms. The fold (10) ensures good electrical contact between the two parts (1, 2) and thus good screening. At the same time, it defines the width of the gap (13), so that the seal (9) is subjected to defined compression.

摘要： A contact pin is operationally connected through racks and pinions to a movable mating contact arrangement in such a way that it executes a movement counter thereto. Through two spokes through which the racks are guided, it bears a contact ring which surrounds it coaxially at a distance and preferably has a radius which is four to eight times as large. In a groove on its outer side, the contact ring bears a circumferential spiral contact which forms with the inner side of a contact tube, which finishes in a fixed nominal-current contact, a sliding contact arrangement having good current transfer in conjunction with a short length.
