Abstract: The invention is based on an electrically insulating material having a matrix of at least one polymer in which at least one insulating mineral, formed in the form of platelets, is included. It is intended to obtain an insulating material which is suitable for the production of insulations which are free of partial discharges even at high voltages and at comparatively high operating temperatures. This is achieved by providing a temperature-resistant thermoplastic as the polymer and by including, as the insulating material, mica microplatelets having a particle size of less than 20 .mu.m. It is further intended to provide a method for producing an electrically insulated conductor in which the insulating material is employed.

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: During switching, a liquid-metal contact film (3) is carried by a moving electrode (2c). When the switch is in the closed-contact state, at least one contact gap (200c) between fixed electrodes (2a,2b) and the moving electrode is electrically bridged by the liquid-metal contact film. Independent claims are included for a current switch, and for electrical switchgear.

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.

Abstract: An electrically and thermally conductive plastic comprising a polymer contg. an embedded semiconductive filler doped to provide a predetermined intrinsic conductivity, the filler amount being chosen such that the electrical conductivity of the plastic remains unchanged with increase in filler quantity. Pref. the filler is a metal-doped ceramic, esp. based on BaTiO3, CdS, Si, SiC, SnO2, SrTiO3, TiO2, YBa2Cu3O7-x and / or ZnO.
