High-voltage insulation bus and coating process

Abstract

The invention discloses a high-voltage insulation bus and a coating process. The high-voltage insulation bus comprises a bus body, the bus body is coated with an anticorrosive layer and an insulationlayer, the anticorrosive layer is positioned on the bottom layer of the bus body, the insulation layer is positioned on the outer layer of the bus body, the anticorrosive layer is coated with organicsilicon coatings, and the insulation layer comprises, by weight, 60-75 parts of organic silicon resin, 40-45 parts of polyacrylate rubber, 5-7 parts of titanate coupling agents, 3-4 parts of zirconiumoxide, 20-24 parts of silicon dioxide, 3-7 parts of naphthenic oil, 4-6 parts of calcium stearate, 3-4 parts of alunite, 5-7 parts of vinyl trimethoxysilane, 2-6 parts of alkali-free glass fibers and9-17 parts of ethylene-propylene-diene monomer glue. A coating structure of the bus can effectively decrease electrical short circuit of the bus body, and the insulating property and the anticorrosive property of the bus are greatly improved, so that the service life of the bus is prolonged.

Description

technical field [0001] The invention relates to the technical field of bus bars, in particular to a high-voltage insulating bus bar and a coating process. Background technique [0002] Insulation safety is very important in electric power safety production, which involves a series of issues such as personal safety and industrial production safety. Among them, short-circuit accidents are one of the important reasons for the frequent occurrence of various electrical insulation accidents. [0003] An important cause of short-circuit accidents is the bare wire operation of the bus itself. The bus is exposed to the environment without protection, and it is easy to cause grounding and phase-to-phase short-circuit due to accidental contact with people, animals (such as mice, etc.) and other objects. Safe operation and power maintenance have caused great potential safety hazards. Another important cause of short-circuit accidents is the overvoltage of the power system. The power i...

Problems solved by technology

[0004] Due to the limitation of objective conditions, various preventive measures widely used at present have certain defects. For example, the use of closed busbars can avoid short-circuit accidents caused by external factors, but the heat dissipation is poor, and the busbars are prone to overheating, which increases the difficulty of maintenance and inspection. The project cost is high, the construction period is long, and the difficulty is great. Generally, it is only used in extremely important occasions, and it is not suitable for large-scale promotion.

Installing insulating baffles between wires is one of the effective treatment methods with low cost, but most of the occasions do not meet the installation conditions
