ABSTRACT:
An electrode system for a high voltage circuit breaker is disclosed which comprises at least one nozzle-like electrode end in which the contour of the end face in cross section in the axial direction of the electrode end forms part of an ellipse. The ellipse may preferably be inclined relative to the axis of rotation of the electrode. The electrode system can be used in circuit breakers with two oppositely-disposed nozzle-like electrode ends and in disconnect switches with only a single nozzle-like electrode end. Concentration of the field at the end face of the nozzle-like end is avoided and thereby dielectric strength is increased.
