Embodiment

[0024] Such as figure 1 Shown, a kind of production method of hollow silicon rubber composite insulator, it comprises the steps:

[0025] (1) Skeleton combination, the mandrel and the shed are bound and combined by thin steel wires to form an integrated structure, and the two ends of the mandrel are also hinged with metal fittings connecting terminals through thin steel wires, and there is an additional set between the mandrel and the fittings The construction of the mandrel in the combination of the correction rod and the skeleton needs to form a hollow hollow structure inside, and there are movable ends at either end or both ends to facilitate the matching of the mold;

[0026] (2) Mold pretreatment, apply mold release anti-sticking glue on the inner surface of the mold, preheat the mold after the glue is applied, and preheat to 80-100°C;

[0027] (3) Put the skeleton in step (1) into the pretreated mold, and mold the mold, seal the mold closing seam after mold closing, and...

Abstract

The invention discloses a method of producing a hollow silicon rubber composite insulator, which comprises the following steps: bundling a core rod and an umbrella skirt with fine wires into an integral structure; hinging a fitting connection terminal to each end of the core rod; adding a correction rod between the core rod and each fitting connection terminal; coating the inner surface of a mold with de-molding anti-sticking adhesive, and preheating the mold; putting a framework in the mold; closing the mold, and sealing the closing seam of the mold; carrying out vacuum pumping; mixing epoxy resin and curing agent according to a mass ratio; pouring the epoxy resin and curing agent after pretreatment into the mold; de-molding an insulator; roughening the outer surface; spraying silicone rubber; sintering the insulator; and installing fittings on the fitting connection terminals at the two ends. The process is simple and convenient. The insulator has a complete structure. The mechanical and electrical properties are greatly improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a production method of a hollow silicone rubber composite insulator. Background technique [0002] Hollow composite insulators are gradually replacing traditional porcelain insulators and stripped insulators with their superior electrical and mechanical properties. Especially in ultra-high voltage or ultra-high voltage transmission and transformation equipment, the superior performance of hollow composite insulators is even more reflected. The existing insulator is composed of an insulating mandrel, a silicone umbrella shed and connecting fittings at both ends. [0003] However, in the existing insulator production process, since the outer surface of the insulator is provided with several groups of sheds, it needs multiple injection molding or assembly to form a complete structure in production, and the main disadvantage of this process in the production process is ...
