Abstract
The invention is directed to a control electrode for high-voltage apparatus which alters the electric field in the vicinity of the voltage-carrying parts. The control electrode includes a formed body of a conductive plastic foam material. The control electrode is suitable, for example, for multipole medium-voltage switching apparatus wherein the pole spacing can be reduced with the air of control electrodes of the invention.
Claims7
In a high-voltage switching apparatus wherein an electric field is present between parts of the switching apparatus separated by an insulating gas, the improvement comprising:
- a control electrode comprising:
- a body of conductive plastic foam material mounted so as to lie in said electric field, said body being formed to have a contour for reducing the intensity of said electric field.
