Abstract: PROBLEM TO BE SOLVED: To supply a high voltage insulation system for using in a high discharge electric field at temperatures not higher than the room temperature. SOLUTION: This is related to the high voltage insulation system appropriate for low temperatures, and further related to a coolant which is equipped with an insulator (2) of a solid material based on cellulose fabric (20). The insulator (2) of the solid material is preferably used by a form of cardboard, and saturated by a polymer resin (21). It has a high partial discharge early phase electric field of 77K, and further this coefficient of thermal expansion most appropriately agrees with that of a ceramic high temperature superconductor. The cardboard is capable of forming in a dry condition especially in order to produce a coil bobbin, and alternately jointed together with cotton fiber, and a laminated material of desired thickness is formed.

Abstract: The invention relates to a current limiting method, a current limiting device (1), and a switchgear comprising such a device (1). According to the invention, liquid metal (3) is directed along a resistor element (5) for the current limiting path (31) so as to obtain arc-free current limitation for mains-related fault currents (i(t)). Examples of embodiments include, among other things: an electrical resistance (Rx) that increases in a non-linear manner in the direction of movement (x) of the liquid metal (3) for a smooth current limiting characteristic; a resistor element (5) in the form of a dielectric matrix (5) comprising channels (3a) for the liquid metal (3), and a combined current limiter-circuit breaker (1). Advantages include, among other things: arc-free, reversible current limitation and optional power shutdown; suitable also for high voltages and currents; fast reaction times; reduced wear; and maintenance-friendly.

Abstract: The present invention relates to a high-voltage insulation system which is suitable for low temperatures and which, in addition to a cooling liquid (3) comprises a solid material insulator (2) based on a cellulose fabric (20). The solid material insulator (2) is preferably used in the form of pressboards and is impregnated with a polymer resin (21). It has a high partial discharge inception field of 77 K and, in addition, its thermal coefficient of expansion is optimally matched to that of ceramic high-temperature superconductors. The pressboards can be formed in the dry stage, in particular to produce coil formers, and are joined together alternately with cotton fabrics to form laminates of any desired thickness.

Abstract: The invention relates to a high-tension installation comprising an active part (1) and a shield (2) having a protective cover (11, 21) made of aluminum hydroxide. The protective cover (11, 21) is formed by hydrating the surface of the active part (1) and/or the shield (21) in water or water vapor at a temperature of 100-120 DEG C. A good adhesive, surface-abrasion and chemically resistant protective cover is thus obtained in a simple, cost-effective and environmentally safe manner, which homogenizes with its relative permittivity to the electrical fields lying close to the surface.

Abstract: The invention relates to a process and a device ( 1 ) for combined current limiting and circuit breaking and to a switchgear assembly with such a device ( 1 ). In a combined current limiter-circuit breaker ( 1 ) as claimed in the invention, a movable electrode ( 3, 3' ) on the one hand for current limitation is guided automatically along one resistance element ( 5 ) for the current limitation path ( 31 ) by an overcurrent-dependent electromagnetic force (F mag ) and on the other hand for circuit breaking is moved into a series arrangement with an insulator ( 8 ). Embodiments include the following, among others: Use of the Lorenz force for automatic current limiting; movable electrode ( 3, 3' ) implemented by liquid metal ( 3 ) or movable solid-state conductor ( 3' ); an electrical resistance (R x ) which increases nonlinearly in the direction of motion (x) for a gentle current limiting characteristic; and a resistance element ( 5 ) in the form of a dielectric matrix ( 5 ) with several channels ( 3 a) for the liquid metal ( 3 ). Advantages are among others: arc-free, reversible current limitation and current interruption, also suited for high voltages and currents, fast reaction times, low wear, and ease of maintenance.

Abstract: A method and an apparatus are disclosed for current limiting, as is a switchgear assembly having an apparatus such as this. Liquid metal is passed along a resistance element for the current limiting path, in order to achieve current limiting without any arcs for network-dependent short-circuit currents. Exemplary embodiments relate, inter alia, to: an electrical resistance, which rises non-linearly in the movement direction of the liquid metal for a soft current limiting characteristic, a resistance element in the form of a dielectric matrix having channels for the liquid metal, and a combined current limiter circuit breaker. Advantages are, inter alia, reversible current limiting and possibly current disconnection without arcs, also suitable for high voltages and currents, fast reaction times, low wear, and maintenance-friendliness.
