Embodiment 1

[0030] like figure 1 As shown, the post insulator with a composite jacket includes a core body 1, an end connector 3 and a composite jacket 2. The core body 1 is made of glass fiber cloth coaxially rolled into a columnar green body and then vacuum-filled with epoxy resin glue. And solidified, or made of multi-strand glass fiber yarns evenly arranged in the axial direction into a columnar body, and then vacuum-filled with epoxy resin glue and cured, or made of multi-strand glass fiber tapes evenly arranged in the axial direction into a columnar shape After the green body is vacuum filled with epoxy resin glue and solidified, there is no solid support such as a rod in the center.

[0031] Process the core body to the required geometric size, then coat the coupling agent on its surface, vulcanize the composite jacket, and carry out surface modification after vulcanization is completed; after the modification is completed, glue the end connectors at the end of the composite jacket...

Abstract

The invention provides a composite jacket pillar insulator and a processing method thereof, and mainly solves the problems that the conventional pillar insulator is easy to crack and bubble, and has high brittleness, poor toughness, poor dielectric strength and mechanical strength. In the composite jacket pillar insulator, a core body is formed by concentrically rolling a glass fiber cloth into acolumnar blank, encapsulating epoxy resin glue in vacuum and curing, or is formed by uniformly arranging a plurality of strands of glass fiber yarns (or a plurality of strands of glass fiber tapes) into the columnar blank along the axial direction, encapsulating the epoxy resin glue in the vacuum and curing. The composite jacket pillar insulator is not layered, has no bubble, high toughness, highdielectric strength and mechanical strength, and high earthquake resistant capability, and is particularly suitable for high-voltage fields.

Description

technical field [0001] The invention relates to a processing method for a post insulator used in the power transmission and transformation industry, in particular to a processing method for a post insulator with a composite jacket. Background technique [0002] At present, the post insulators used in the power transmission and transformation industry mainly include all-ceramic post insulators, all-ceramic mandrel composite jacket post insulators, hollow bushing composite jacket post insulators, and composite jacket post insulators with epoxy glass fiber pultruded rods as core rods. There are several structures such as composite sheath post insulators with core rods impregnated with epoxy resin and pultrusion rods externally rolled. [0003] The above structure has many defects and problems from the actual operation experience and processing technology: the all-ceramic post insulator is heavy, poor in toughness, easy to be brittle, and has poor electrical insulation performan...
