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

Abstract

The invention discloses a high-voltage insulated bus and a coating technology, and relates to the technical field of bus production. The high-voltage insulated bus comprises a body, wherein the body is coated with a base coat layer and a finishing coat layer; the base coat layer is formed by coating with any one of epoxy coating, acrylic acid coating or organic silicon coating, and the thickness is 15-25mum; the finishing coat layer is formed by coating with the organic silicon coating, and the thickness is 10-15mum. According to the high-voltage insulated bus and the coating technology disclosed by the invention, field modulation is not needed, the construction is convenient, the insulating safety can be remarkably improved, and the service life of the bus is prolonged.

Description

technical field [0001] The invention relates to the technical field of busbar manufacturing, in particular to a high-voltage insulated busbar 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. T...
