Insulation body splicing structure of super-large CT slip ring

The invention discloses an insulation body splicing structure of a super-large CT slip ring. The insulation body splicing structure comprises two or three layers, wherein each layer has at least two valves, two adjacent valves are positioned and assembled radially through a stepped straight mouth, and the layers are bonded concentrically through high-strength epoxy resin glue, so that the raw material is easier to manufacture and is lowered in cost, and the structure strength of the insulation body is ensured. The whole insulation body is immersed in paint in a vacuum environment, so that a compact, uniform and hard insulation paint membrane is formed on the surface of the insulation body so as to effectively ensure the insulation performance and electrical performance indicators of the insulation body.
