Technology for internal surface small space protection in air flue of dry-type air-core reactor
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. 1.
