Description

Technical Field

[0001] The utility model relates to the technical field of transformer production, in particular to a transformer surface insulation layer coating device. Background Art

[0002] Before the transformer is put into use, it is necessary to coat the outer wall of the transformer with insulating paint for corrosion prevention and insulation. The insulating paint can form a protective film on the outer wall of the transformer to prevent harmful gases such as oxygen and sulfur dioxide in the air from corroding the surface of the transformer, thereby extending the service life of the transformer. At the same time, it can also prevent the influence of physical and chemical properties, such as corrosion, scratches, dirt, etc., and can also enhance the insulation effect of the outer wall of the transformer. However, when the existing coating equipment is spraying the outer wall of the transformer, it is usually sprayed directly with paint. Before spraying, the debris attached to the surface of the outer wall of the transformer is not cleaned accordingly, which can easily lead to poor adhesion of the paint after spraying, thereby affecting the protective effect of the paint on the outer wall of the transformer.
