摘要： The arrangement of the outer electrode of a capacitive voltage transformer designed as a capacitor in a completely insulated, metal-encapsulated electrical switching section is disclosed. The outer electrode comprises a tube which is arranged coaxially in a tubular jacket of the metal encapsulation and is fastened, electrically insulated, to the tubular jacket. The inner electrode of the voltage transformer is a conductor concentrically arranged in the tubular jacket. Between the tube and the tubular jacket, an insulating tube section is arranged. An insulating bushing extends through the wall of the insulating tube section and the wall of the tubular jacket. The insulating bushing is mounted on a metallic bushing. A head screw clamps the insulating tube section between the tube and the tubular jacket, and a flange of the insulating bushing is clamped between the outside of the tubular jacket and a flange of the metallic bushing. A voltage take-off is secured to the metallic bushing.
