SHIELD FITTINGS FOR HIGH-VOLTAGE INSULATION STRUCTURES (EMBODIMENTS) Russian patent published in 2022 - IPC H01B17/42 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and power engineering, namely to screen fittings for high-voltage insulation structures. Disclosed screen fitting contains two rings of different diameters connected to each other by means of spacer 1, and fastening element 2. Ring 3 with large diameter is made with arc-shaped section, centers 4 of arc radius are located in inner area of screen fitting. Ring 5 with smaller diameter can be made in the form of a circle, oval, polygon or any geometrical figure. Rings 3, 5 are composite, for example, consist of two elements. Ring 3 with large diameter is made with arc-shaped section, centers 4 of arc radius are located in inner area of screen fitting. Ring 5 with smaller diameter of geometrical figure.

EFFECT: use of the invention makes it possible to increase efficiency of screen fittings, to equalize electric field of high-voltage insulator by means of considerable reduction of specific material consumption of screen fittings.
