Problems solved by technology

[0003] ①Due to sandblasting damage to the smooth layer on the surface of the insulating part, the moisture-proof and dust-proof effects of the insulating part are seriously reduced;
[0006] The degree of adhesion is not ideal, the surface of the product is rough, the moisture-proof and dust-proof effect of the ground layer is not good, what is more serious is that the ground layer is easily damaged by external forces, and a little carelessness may cause the ground layer to lose its effect

Embodiment 1

[0024] Embodiment 1: the production technology of 12KV solid insulation box, carry out according to the following steps:

[0025] A. Mold processing process: manufacture the mold according to the process of solid insulation box, polish the processed mold until it reaches the effect of mirror surface; harden the polished mold with nitriding to enhance the strength of the mold; after that According to the design requirements, different textures are first formed with negative films, and then pasted on the mold, and the mold is corroded with an industrial corrosive agent, so that the surface of the product has a special texture, thereby completing the treatment of the mold;

[0026] B. Mold production stage: install and clean the above-mentioned processed mold, and then heat the mold. The heating temperature is preferably 135°C-145°C, and the heating time is preferably 0-3min. After the completion, spray liquid conductive material on the surface of the mold. The conductive materia...

Embodiment 2

[0031] Embodiment 2: The production technology of 24KV solid single-phase melting bin, carry out according to the following steps:

[0032] A. Mold processing process: The mold is manufactured according to the process of solid single-phase melting bin, and the processed mold cavity is polished until it reaches the effect of mirror surface; the polished mold is hardened by nitriding to enhance the strength of the mold Intensity; then according to the design requirements, the different textures are first formed with negative films, and then pasted on the mold, and the mold is corroded with an industrial corrosive agent, so that the surface of the product has a special texture, thereby completing the treatment of the mold;

[0033] B. Mold production stage: install and clean the above-mentioned processed mold, and then heat the mold. The heating temperature is preferably 140°C-150°C, and the heating time is preferably 0-3min. After completion, spray a liquid conductive material o...

Abstract

The invention discloses a solid insulating piece surface treatment technology comprising sixteen steps of mould cavity manufacturing, mould cavity polishing, mould cavity hardening treatment, mould cavity photographic corrosion, mould installation and cleaning, mould heating, conductive material spraying, adhesive spraying, embedding piece installation and heating, material injection, temperature and pressure maintaining curing molding, product de-molding, product cleaning, curing after high temperature, examination, warehousing, etc. With special treatment on a mould and combination of corresponding production technology, a conductive grounding layer which is fused with insulating materials can be additionally arranged on the surface of a solid insulating piece, and appearance of the insulating piece can also be beautified. The solid insulating piece surface treatment technology is simple in technology, and the prepared product is great in insulating performance, great in dustproof and moisture-proof effects, reliable in operation and high in adaptive capacity to environment.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to a novel surface treatment process of a solid insulating part. Background technique [0002] There are many types of insulating parts in high-voltage power distribution equipment. According to specific functional requirements, the surface treatment of insulating parts is also different. In recent years, as the State Grid Corporation has higher and higher requirements on the performance of electrical equipment, the requirements on the environmental adaptability and partial discharge of the products have become more and more stringent. An innovative process proposed by the company for the new requirements of electrical equipment, especially the newly launched solid insulated ring network cabinet for distribution network engineering. The current commonly used technology in China is to completely spray the outer surface of the insulating part with the gr...
