STEUNISOLATOR MET STUURELEKTRODE VOOR PLAATSING IN EEN GASGEVULDE HOOGSPANNINGSBUIS EN STUURELEKTRODE DAARVOOR.

摘要

This invention concerns a control electrode which is attached on the side adjacent to the inner conductor of an essentially conical support insulator between the inner and the outer conductor an an encapsulated, gas-insulated tubular line. The cross section of the control electrode is asymmetrical. The radius of curvature of the outer wall of the control electrode is increasing from the half of wider cross section toward the narrower half. With the invention, a gradual decrease of the field at the support insulator is achieved without stressing the support insulator with excessive voltage values per unit length.
