HIGH VOLTAGE ARRANGEMENT COMPRISING AN INSULATING STRUCTURE

摘要

It is presented a high voltage arrangement (1) for a high voltage power system. The high voltage arrangement (1) has an insulating structure which reduces the creep path in the insulating structure. The high voltage arrangement (1) comprises an insulating structure (6) arranged around the second conductor (13) for providing insulation of the second conductor (13), wherein the insulating structure (6) has a continuous extension in an axial direction from a first end (21-1) thereof providing insulation of essentially the entire length of the second conductor (13) to a second end (21-2) of the insulating structure arranged around the bushing portion (11-1), which second end (21-2) extends around the bushing portion (11-1) at least to a point where an electric potential of an external surface of the bushing portion (11-1) is at most equal to the average of the potential of the first conductor (9) and the potential of the interfacing plane (4) when the high voltage arrangement (1) is in use.
