Title:
A DEVICE FOR ELECTRIC FIELD CONTROL
Document Type and Number:
WIPO Patent Application WO/2013/004748
Kind Code:
A3
Abstract:
A device for controlling an electric field at a high voltage component comprises an inner deflector (4) to be electrically connected to a live high voltage part (1) of the high voltage component; a resistive layer (5) adapted for field controlling purposes, to be arranged along the high voltage component, and which at one position is to be electrically connected to the live high voltage part (1) of the high voltage component and at one end is adapted to be electrically connected to a grounded part of the high voltage component, the resistive layer having a nonlinear current-voltage characteristics; an insulating layer (6) arranged on the resistive layer and extending at least from the one position towards the one end of the resistive layer while ending without reaching the one end of the resistive layer; and a semi-conducting or conducting layer (7) arranged on the insulating layer and extending at least from the one position towards the one end of the resistive layer and past the end of the insulating layer, thereby defining an outer triple point at the intersection of the resistive layer, the insulating layer, and the semi-conducting or conducting layer. The resistive layer has first, second, and third adjacent sections as seen from the one position towards the one end, wherein a portion of the first section extends below the inner deflector.
