Transformer vacuum paint-dipping process

The invention discloses a transformer vacuum paint-dipping process and belongs to the technical field of transformer production. The process includes that the mode of vacuum breaking is adopted during painting, namely when vacuum extraction of a paint dipping tank reaches 0.06MPa and the paint face of insulating paint ascends close to the bottom of a transformer thimble, an air incoming valve of the paint dipping tank is opened to let air in, vacuum breaking state is formed in the paint dipping tank instantly to enable the air pressure inside the paint dipping tank to be an atmosphere; meanwhile, the inside of a transformer is still in an absolute vacuum state of 0.06MPa, the insulating paint in the paint dipping tank can be extruded into 95-98% of the space inside the transformer by the outside atmosphere and enters into the bottom of the transformer due to the gravity in only 1-2 seconds; soon afterwards, in the process when the air incoming state is maintained, the insulating paint continuously and slowly flows into the transformer due to the capillary action of liquid to totally cover the inside space of the transformer. Consequently, insulating effect of the transformer is improved, and moisture resistance, heat resistance, conductivity, magnetoconductivity and mechanical performances of the transformer are guaranteed.
