摘要： The short-circuit current switching-off capability of a high-voltage autocompression compressed-gas switching chamber is intended to be increased by centring the switching-off arc in the axis space especially of stationary or movable double-nozzle arrangements. To this end, an arc centring device is proposed which is characterised essentially by the structural connection of the following components: a current conducting and/or gas outlet tube (7) and a tube (47) consisting of ferromagnetic material are connected without any spacing between the tube sections to form a double tube arrangement. A nozzle is inserted into the double tube arrangement. In the region of their ends facing the nozzle, the tube sections of the double tube arrangement are electrically conductively connected to one another. Outside this region, an insulating layer prevents current transfer between the tube sections. The insulating layer advantageously consists of potassium silicate or sodium silicate (water glass). The ferromagnetic tube is protected against arc erosion by an inserted tube consisting of erosion-resistant material.

摘要： In a high-voltage compressed-gas switching chamber in accordance with the autocompression method, and having stationary double nozzles, it is intended to prevent electrical partial discharges (which occur during both switching on and switching off and reduce the dielectric strength of the contact gap) between the wall of the opening in the base of the compression cylinder and the conductive material nozzle. The invention achieves this object by making electrical charges of different polarity comparable and by charge equalisation. According to the one solution method, an electrically conductive filling material, for example graphite or metal powder, is added to the base of the compression cylinder, which is produced from insulating material, in the region of the opening in order to make the electrical surface charges and the electrical field caused thereby comparable. Said addition is expediently carried out such that the shape of a body of revolution is produced by the distribution boundary. In order to make the electrical field homogeneous, the soffit of the opening in the base of the compression cylinder can also be metallised. According to the other solution method, the gap between the soffit of the opening in the base of the compression cylinder is electrically short-circuited. For this purpose, a metal-brush-like device is fitted either to the wall of the opening in the base of the compression cylinder, or in the end region of the conductive material nozzle, in order to "wipe off" the electrical charges.

摘要： In a high-voltage switch according to the main patent application with the file reference P 3103373.3, a central drive housing is mounted on a supporting insulator and three switching units are mounted in the form of a star on this housing. In one embodiment variant of the primary idea of the invention: statically compensated arrangement, dynamically balanced drive of three switching units, these switching units are now placed on parallel axes in a tank, to be precise such that not more than two supporting insulators are required for their support and insulation with respect to earth. The three switching units are driven centrally by means of a common main drive. The switching units are connected thereto via in each case one switching rod. Electrically, the three switching units are connected in series such that the connecting pieces have a minimum length, which leads to the geometric shape of a lying "S".

摘要： The circuit breaker can switch ohmic, capacitive, small inductive, and combined currents, as well as a short circuit. It provides an insulating path of high strength. It has a swivelling, lever-shaped, insulating component for the drive of the switchable current contacts. The drive lever (7) is laterally mounted in a moving manner to the support insulators (3,4) of a breaker pole. On the side of the stationary permanent current switching contact (13) is mounted a breaker system (15) in the form of an independent module with all components for the current interruption. In the broken state the separating path (12) lies between the support insulators. The breaker system, the moving current switching contact, and the stationary switching contact do not protrude into the separating path, or only slightly.

摘要： The arrangement has a switch arrangement in a circuit supplying electrical power to a load (2). The switch arrangement is controlled to produce automatically repeating operating intervals of the load. Two switches are connected in series in the load circuit. The first switch (3) is controlled with time and the second (4) is a photo-switch controlled according to light intensity variations. The opening and closing of the switches is matched so that power is fed to the load in an automatically repeated sequence according to the elapsed time and the variations in light intensity.

摘要： The axial magnetic field contact arrangement has a current conductor with a skeletal form. This has a cylindrical disc (1) that has three radial channels (5) that are curved and expand in width and so create three curved radial spokes (4). The spokes can have the form of an Archimedean or logarithmic spiral with an overlapping region (8) for the free section (2). The outer sections (2) can be mechanically reinforced by coupling elements (15) that pass into main body of the spokes (4). A contact and electrode disc (9) fits over the end. A casting process can be used for the manufacture of the skeletal shape.

摘要： The axial magnetic field contact arrangement has a magnetising disc (3) with a cylindrical shape and having four radial slots (4) with the form of an Archimedean spiral over part of the length and this provides eddy current damping. The disc has a relatively narrow edge (6) for the location of a winding section (7) that provides overlapping of two adjacent segments (8) created by the slots. The maximum overlapping is when the edges of the slots are reached. A contact and electrode disc (14) is located on a plane disc (9) between the parts.
