Abstract: An electrical circuit breaker (10) comprises an enclosure (12) filled with an insulating fluid. Within the enclosure (12) is a pair of opposing contacts (14 and 16) one of which is fixed and the other moves axially relative thereto. When the contacts (14 and 16) are separated an arc is drawn between them. The arc is rotated by a magnetic field generated by coil (18). A shield (20) prevents the arc short circuiting the coil (18) but also traps ionised gas particles and metallic vapours. To prevent the ionised gas and vapours building up a flow of purging gas is directed through channels (26 and 28) to region A. The purging flow of gas flushes out this region to prevent re-establishment of the arc.

Abstract: An electrical compressed gas power switch for high voltages has two coaxial contact elements (1, 2) at least one of which (the bridging contact element) can be driven, and an insulating unit (5, 7, 13) which is connected to the bridging contact element, grips around the second contact element (2) when in closed-circuit condition so as to form a gas-tight seal, and defines a compressed gas chamber (6). The second contact element (2) has a tapering section in its end region (11), ensuring that, before the axial grip around the second contact piece (2) by the insulating element (5, 7, 13) is broken, a gap (16) is created between the second contact element and insulating unit through which quenching gas from the compressed gas chamber (6) can flow in order dielectrically to stabilize the intermediate space between the insulating unit and second contact element (2) and dielectrically to unload the drain point of the insulating unit and the second contact element.

Abstract: The invention relates to a high-voltage circuit breaker according to the self-blast and/or puffer-type principle. The main current path of the circuit breaker is made of tube of a plastically machinable material, preferably copper or a copper alloy. The blast piston (28) of the circuit breaker and any other components included in the circuit breaker, such as a guide (29) for the operating rod, etc., are fixed to the respective current path section (26) by pressing the plastically machinable material in the current path into a prepared groove (31, 32) in the respective component (28, 29). The blast piston (28) may alternatively be directly integrated into the respective tubular current path section (26) by curving the end portion of the tube inwards in such a way as to create an annular bottom forming a blast piston.

Abstract: In a high-voltage power switch with an arc contact (1) and a spatially separate rated current contact (6), the moving part of the rated current contact (6) takes the form of an external hollow cylinder to delimit a storage space (11) for pressurised quenching gas. The hollow cylinder (10) is made of a one-piece precision casting of contact material, especially a CuCr alloy, the jacket of which is stiffened by three inwardly projecting flange-like projections (12, 13, 14). This design provides a light structure of a bridging circuit component for a rated current contact requiring comparatively little driving power for its operation.

Abstract: The aim of the present invention is to control the electric field in the region of the switching path of a compressed gas switch with the aid of field electrodes. In a compressed gas switch (1) with two mutually coaxial contacts (5, 6) and hollow nozzles (8, 9) to remove extinguishing gas and a stationary cylindrical heating chamber (12) coaxially surrounding the nozzle gap (11) and communicating therewith, at least parts of the frontal limiting wall of the heating chamber (12) are formed by electrodes (15, 17) to control the electric field in the switching path. In addition there is a compression chamber (13) on the side of the heating chamber opposite the operating side of the switch (1). The invention is applicable to all compressed gas switches fitted with a heating chamber for the extinguishing gas.

Abstract: In a compressed gas switch with two switching components between which an arc forms on switch-off and a tubular electrically conductive sleeve (2) in the central axis of which is arranged one switching component (5) and which has several lateral apertures (12) in the region of one of its ends opposite to the two switching components, flashbacks can occur which is caused by pressure waves within the sleeve (2). The sleeve (2) is surrounded at a short distance by a casing which either consists of porcelain or is electrically conductive and earthed. To prevent flashbacks, the sleeve (2) has several lateral apertures (13) and a pressure wave barrier in the region facing both switching components which contains a cross-section-reducing component (11).

Abstract: In a compressed gas switch with a blowing device (5) consisting of a piston (6) and cylinder (7) and two separable switching components (1, 4) which are hollow in order to discharge the switching gas, one (1) of the switching components is fixed. In the "on" position, the latter penetrates a frontal aperture (8) in the cylinder (7). To reduce any gas loss on switching off, the frontal aperture (8) is bordered by a flexible sealing lip (9) made up in several parts by sections uniformly distributed about the periphery.
