Fluid insulated high voltage coil

摘要

Exemplary embodiments include a fluid insulated high voltage coil having closed tank for an insulation fluid and a high voltage coil arranged therein with at least two taps. An insulation tube extends into the tank, where the inner part of the tube is accessible from an outer side of the tank. Electric contact elements extend through the tube walls along its longitudinal axis, where at least some of the contact elements are electrically connected with the taps. A removable column-like electrical interaction device is arranged within the inner part of the insulation tube, which is electrically connected to the at least two taps by means of the contact elements.
