Problems solved by technology

However, the problem of microcracks in the encapsulated insulation of dry-type air-core shunt reactors belongs to the industry, and has not attracted the attention of universities and research institutions at home and abroad for a long time.
There is no relevant report on the research on the formation mechanism of micro-cracks in the encapsulation insulation of dry-type air-core shunt reactors, and there is still no effective solution for the detection and repair of micro-cracks in the encapsulation insulation

Abstract

The invention relates to the technical field of light-cured acrylate materials, and particularly relates to an acrylate material capable of being quickly cured by visible light and a preparation method thereof. The acrylate material comprises an acrylate monomer, an adhesive Bis-GMA, a bifunctional diluent monomer TEGDMA, CQ and DMAEMA, wherein acrylate material comprises x parts of the acrylate monomer, 7-x parts of the adhesive Bis-GMA, 3 parts of the bifunctional diluent monomer TEGDMA, the CQ and the DMAEMA; the x is greater than or equal to 0 and less than or equal to 7; the mass of eachof the CQ and the DMAEMA is 1% of the total mass of the acrylate monomer and the bifunctional diluent monomer TEGDMA. Fluorine-containing acrylate with low viscosity and high double-bond conversion rate is synthesized, is used as novel matrix resin of a photocuring repair material, and can be used as an encapsulation insulation micro-crack healing material of a dry-type air-core shunt reactor to realize effective repair of encapsulation insulation micro-cracks, so that an encapsulation insulation fault of a dry-type air-core shunt reactor is solved.

Description

technical field [0001] The invention belongs to the technical field of photocurable acrylate materials, and in particular relates to a fast visible light-curable acrylate material and a preparation method thereof. Background technique [0002] Due to the advantages of small maintenance, low cost, and easy installation, dry-type air-core reactors are widely used in power systems. Dry-type air-core shunt reactors are mostly made of glass fibers impregnated with epoxy resin to encapsulate and insulate the coils, and then cured at high temperature to complete. Since dry-type air-core reactors were used in my country in the 1980s, dry-type air-core reactors have been burned out one after another, and all faulty dry-type air-core reactors have cracks to varying degrees in the envelope insulation. However, the problem of microcracks in the encapsulated insulation of dry-type air-core shunt reactors belongs to the industry, and has not attracted the attention of universities and re...
