Technology for internal surface small space protection in air flue of dry-type air-core reactor

Abstract

The invention provides a technology for internal surface small space protection in an air flue of a dry-type air-core reactor. According to the technology for internal surface small space protection in the air flue of the dry-type air-core reactor, the inner surface of the air flue of the dry-type air-core reactor is processed. The technology comprises the following steps that dust in small space of the inner surface of the air flue of the air-core reactor is removed through a dust collection device, the bottom of the cleaned air flue of the air-core reactor is plugged through a plugging device, and therefore the air flue of the air-core reactor becomes a semi-closed container; paint is injected into the air flue of the air-core reactor, the air flue of the air-core reactor in the step (b) is dipped and coated, standing of the paint in the air flue of the air-core reactor is conducted for a period, the plugging device at the bottom of the air flue of the air-core reactor is detached after the paint is recycled, and quality detection is conducted on the treated air flue of the air-core reactor. According to the air-core reactor protected through the technology, the probability that due to the fact that water vapor molecules permeate through the air-core reactor, short circuits among wire turns of the air-core reactor are caused and then the air-core reactor is damaged is greatly reduced, and the service life of the air-core reactor is prolonged.

Description

technical field

[0001] The invention relates to a protection process for a dry-type air-core reactor, in particular to a protection process for a small space on the inner surface of a dry-type air-core reactor. Background technique

[0002] The climate in the southern region is humid and rainy, the air humidity is high, and the annual average humidity is above 80%. Epoxy resin, one of the manufacturing materials of dry-type air-core reactors, will gradually lose its The original mechanical properties and insulation properties will become brittle, the mechanical strength will be weakened, and it will be easily broken down. This process is also the aging process of epoxy resin. In general, the higher the temperature, the faster the mechanical and insulating properties of the epoxy resin will weaken; the more moisture the epoxy resin contains, the faster it will age. At present, for the surface protection of the small space in the reactor air duct, due to the limitations of th...
