Abstract

The invention belongs to the field of GISs, and particularly relates to a GIS enamel technology. The GIS enamel technology comprises the steps of roughening treatment, coating pretreatment, coating treatment and coating post-treatment which are sequentially conducted on a GIS shell part. Roughening treatment comprises that after the GIS shell part is subjected to sand blasting or shot blasting treatment, a Ra value of the surface roughness of the GIS shell part reaches 11-13, coating pretreatment comprises that the GIS shell part which is subjected to roughening treatment is sequentially subjected to degreasing, bright dipping, passivating, rinsing, water blowing and drying, coating treatment comprises that the GIS shell part which is subjected to coating pretreatment is sequentially coated with primer, putty, intermediate coat and enamel paint, and coating post-treatment comprises that polishing treatment is conducted on the GIS shell part which is subjected to coating treatment. According to the GIS enamel technology, a prepared GIS shell is bright in surface gloss, full and attractive, and has no particle or impurity, and the production cost is reduced while the quality of a GISmodel machine is improved.

Description

technical field [0001] The invention belongs to the field of GIS switches and relates to a GIS enamelization process. Background technique [0002] SF 6 Closed combined electrical equipment (Sulfur hexafluoride full metal-enclosed high-voltage electrical combined switch, hereinafter referred to as "GIS"), uses sulfur hexafluoride gas with excellent insulation performance as the insulation and arc extinguishing medium, and converts all components in a substation except transformers Primary equipment, including circuit breakers, isolating switches, grounding switches, voltage transformers, current transformers, lightning arresters, busbars, cable terminals, inlet and outlet bushings, etc., are organically combined into a whole through optimized design, which can greatly reduce the size of the substation. volume to achieve miniaturization. [0003] The appearance of the existing GIS prototypes in my country still has a certain gap compared with Europe, America, Japan and othe...
