APPARATUS AND METHOD FOR DAMPING VIBRATIONS IN HIGH-VOLTAGE DEVICES

An apparatus for damping vibrations in high-voltage devices has a support arrangement for the high-voltage device. The support arrangement includes support elements interconnected by connection elements. Intermediate elements, in particular coated washers, are arranged between the connection elements and the support elements and/or between different support elements. There is also described a method for damping vibrations, in which connection elements spatially fix support elements of the support arrangement of a high-voltage device in a mechanically stable manner. When mechanical vibrations occur on the high-voltage device, the connection elements dampen the mechanical vibration in a defined manner via a predetermined sliding friction with the support elements and via a spatially predetermined play in relation to the support elements.
