Abstract: The present invention relates to a current distributing circuit arrangement (20, 20?), adapted for charging a plurality of arrays of co-ordinated energy supplying DC-networks (“A” (DC)), (“B” (DC)), wherein the circuit arrangement (20) includes a plurality of setup-related circuits (21, 22, 23, 24) each of which is adapted to a pre selected energy supplying DC-network, (“A” (DC)) with, inter alia, its allocated terminal voltage (350V DC), its allocated capacity and/or its allocated maximized loading current. Respective circuit arrangements (20, 20?) can be allocated an AC-supplied rectifying bridge (21), an after-coupled sinus pump unit (23) and a DC/DC-converter (24) that includes a maximum current limiting circuit (43).

Abstract: The present invention comprises an electronic element (2a), fitted or adapted for an electric circuitry or circuit arrangement (1), where said circuitry inter alia is constituted by a voltage source (1a, 1b), a supply voltage and a current feeding unit (2) switching on or switching off a load, and an interlocking circuit (2a) connected between the unit and the load (1c), where said interlocking circuit is assigned a function fitted or adapted for switching on or switching off current, in order to achieve a switch-on or switch-off free from sparks or arcs of the load current (“Ib”) of a selected load (1c) via said element (2a). Said interlocking circuit is structured as an electronic element where a switch-on of voltage to said electronic element (2a) causes the activation of circuits belonging to the element in order to, after the switch-on of voltage and by a trigger signal, cause the load current (“Ib”) to said load (1c) to be increased.

Abstract: An overvoltage protector in an apparatus having two moving parts (1,5). The parts are connected via a bearing (2,3,4), one part being stationary in relation to a substructure (13) at an electrical ground potential. The moving part (5) can be subjected to a voltage and the stationary part (1) is electrically connected to the grounded substructure. For preventing current from passing through the bearing between the parts, an electrical insulator (6,7) is provided in the current path which can occur through the bearing as a result of different potentials of the parts. The moving part (5) has a ring (9) spaced from a ring (8) connected to electrical ground such that a spark discharge gap (10) is formed between the parts. The bearings (2,3,4) are protected against current flow by the electrical insulator (6,7) up to a given voltage threshold.
