Abstract

In electrical devices connected to high-voltage, especially machine and mains transformers, components (3, 5) for the electrical and mechanical connection of the end of a feedthrough conductor bolt (3) to a connecting conductor (12) carrying high-voltage are often arranged in a chalice-shaped screen (4). According to the invention, in order to damp high-frequency switching oscillations a low-inductance fixed resistor (9), forming the end of the connecting conductor (12), is spatially and electrically arranged between the chalice-shaped screen (4) and a chalice-shaped screening pot (10) similar to said screen, an iron-free choke winding (8) carrying the load current being provided electrically in parallel with, and spatially coaxially with respect to, the fixed resistor (9), which choke winding (8) grips the screening pot (10) with its one end and the screen (4) with its other end. The combination of a high-voltage feedthrough (2) with a damping element for oscillations in the MHz range is especially expedient in cases in which a 400 kV transformer is directly coupled to an SF6 switching device. <IMAGE>
