Abstract
An insulating component for use in high-voltage switching equipment, especially gas-insulated switching gear. A nozzle made of an insulating material is used in a power switch. Portions of the surface of the nozzle subject to high dielectric stresses in use are provided with increased surface roughness in the form of grooves. These grooves may be cut by a lathe.
Claims11
An insulating component for a high-voltage switching equipment, comprising:
- at least one region having a high dielectrical stress level and a roughness depth of at least 100 .mu.m, the at least one region accommodating at least one of sharp-edged grooves and sharp-edged ridges on a surface of the insulating component;
- and
- an arrangement limiting a potential of surface charges along the at least one region.
A method for producing an insulating component of a high-voltage equipment, comprising the steps of:
- forming the insulating component including an arrangement limiting a potential of surface charges along at least one region, the at least one region being capable of experiencing high dielectric stresses;
- and
- machining a plurality of at least one of grooves and ridges into the insulating component in the at least one region.
