Electrical Insulation System

摘要

An electrical insulation system for a high voltage inductive device includes a cylindrical insulation barrier defining an axial direction, a longitudinal bar having a main extension in the axial direction, the longitudinal bar arranged to support the cylindrical insulation barrier along the axial direction and to provide spacing in a radial direction, and the longitudinal bar having a first side facing the cylindrical insulation barrier and a second side, opposite the first side, having a groove, and a spacer having a main extension in the radial direction, the spacer being arranged to provide spacing in the axial direction, the spacer having a groove fitting end portion. The longitudinal bar is adapted to receive the groove fitting end portion of the spacer in the groove, and wherein the spacer is dimensioned so relative to the groove that the groove captures any streamer propagating from the spacer towards the cylindrical insulation barrier.
