Problems solved by technology

At present, for the surface protection of the small space in the reactor air duct, due to the limitations of the existing technology and tools, the paint cannot be fully and effectively attached to the inner surface of the small space of the reactor air duct, so that the inner surface of the air duct has not been effectively protected. , which leads to the reduction of the waterproof and moisture-proof performance of the small space on the inner surface of the air duct. During the operation, it is easy to accelerate the aging of the epoxy resin of the reactor, thereby inducing equipment accidents such as short circuit between turns, which seriously affects the normal service life of the reactor. It affects the safe operation of the power grid and causes unnecessary economic losses to the power sector and the majority of power users

Embodiment 1

[0030] Such as figure 1 As shown, the protection process of a small space on the inner surface of a dry-type air-core reactor air duct of the present invention mainly includes the following steps:

[0031] The first step is to use a dust removal device to remove the dust in the small space on the inner surface of the reactor air duct; use an electric small brush or a rag to clean the small space on the inner surface of the reactor air duct, and then use a dust removal spray gun to blow off the dust to ensure that the inner surface of the air duct is clean .

[0032] The second step is to block the bottom of the reactor airway; use a rubber airbag that matches the specifications of the reactor airway to block, and the rubber airbag is equipped with a T-shaped copper iron pipe for support. First, place the rubber airbag Fill the bottom of the reactor airway, and then inflate the rubber airbag to a certain extent through the gas distributor to block the bottom of the reactor air...

Embodiment 2

[0039] In a protection process for the small space inside the air duct of a dry-type hollow reactor, the blocking device in the second step is made of fireproof mud or rubber, silicon rubber and other materials with a valve to recover the diversion pipe, and the bottom of the reactor air duct is equipped with The supporting plate, the supporting plate exerts force on the blocking device, and blocks the bottom of the reactor air passage; complete the removal of the blockage at the bottom of the reactor airway; or remove the construction operation that makes the reactor airway into a semi-enclosed container environment in other ways, and complete the removal of the bottom blockage of the reactor airway.

[0040] In this embodiment, other implementation steps are the same as those in Embodiment 1, and will not be described here one by one, and the invention objective of the present invention can also be achieved.

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...
