Problems solved by technology

[0009] The purpose of the present invention is to propose a new on-site repair method for damaged composite insulator sheds to solve the problems that the existing methods are not convenient for on-site construction, and the time is long, the tools are heavy, and the efficiency is low; the present invention also provides a fast Repair glue, the quick repair glue adopts a unique formula and preparation process, so that it can cross-link with the surface of the shed to be repaired and form an integral body. After vulcanization, the physical, chemical and electrical properties of the original shed material are basically the same. The damaged part of the shed can be completely restored, so that the physical and electrical properties of the composite insulator of the damaged shed can be completely restored, especially the mechanical strength and breakdown strength can exceed the requirements of industry technical standards, and the service life is long

Abstract

The invention discloses a field repair method for a damaged composite insulator shed. The method comprises steps: the surface of a damaged part repair contact surface of the composite insulator shed is preprocessed; a composite insulator shed quick repair adhesive which can be vulcanized under a high temperature is prepared; the composite insulator shed quick repair adhesive is pressed in a roughshape of a damaged and missing part, and the surface is contacted with the surface of the damaged part; a tool is used to press the composite insulator shed quick repair adhesive towards the damaged part, the composite insulator shed quick repair adhesive fills the damaged part and is compacted, and thus, the surface contacted with the damaged part is tightly contacted with the surface of the damaged part; the damaged part is heated under a high temperature, the quick repair adhesive filling the damaged part on the composite insulator shed is heated, crosslinking happens to the material at theoriginal damage part and the quick repair adhesive, and the material at the original damage part is activated to participate in vulcanization treatment on the quick repair adhesive. The invention also discloses a quick repair adhesive executing the above method.

Description

technical field [0001] The invention relates to a manufacturing technology of composite insulators for power transmission and transformation lines, in particular to a field repair method and quick repair glue for damaged composite insulator sheds. Background technique [0002] Composite insulators started in the 1950s and have a history of more than 60 years. my country's silicone rubber insulators were put into production in about 1967, and the production has been running for more than 50 years. There are thousands of domestic high-voltage composite insulators in operation in the power system. With the implementation of my country's UHV power transmission projects , the west-to-east power transmission project is further developed, and the demand for high-voltage composite insulators will increase significantly. [0003] The composite insulator is mainly composed of three parts: glass fiber epoxy resin lead rod, silicone rubber shed, and hardware. Among them, the silicone r...
