Embodiment 1

[0034] Please see figure 1 , is a flow chart of a preferred embodiment of the coating process for a solid insulated switchgear insulation box of the present invention, including the following steps:

[0035] S1. Assembly: Assemble the three-phase vacuum interrupter and its corresponding conductive connections, isolating switch, grounding switch, main busbar, branch busbar and other main conductive circuits respectively;

[0036] S2. Encapsulation: Encapsulate the assembled three-phase interrupter and its corresponding conductive parts with a solid insulating medium to form an insulating box shell;

[0037] S3, pressing: preheating the pressing mold, after the preheating is completed, use the pressing mold to press the surface of the insulating box shell, and after the pressing is completed, cool and demould the insulating box;

[0038] S4. Pretreatment of the surface of the insulation box: Use water-based biodegradable cleaners to remove oil, water, grease, salt, etc. on the ...

Abstract

The invention provides an insulating box coating technology for solid insulation switch equipment. The insulating box coating technology comprises the following steps: S1, assembling; S2, coating andpackaging; S3, pressing; S4, carrying out surface treatment on an insulating box; S5, immersing through a silane coupling agent; S6, spraying and coating first-layer epoxy resin coating; S7, sprayingand coating second-layer epoxy resin coating; and S8, spraying and coating a finish paint layer. The silane coupling agent is used for immersing, so that the combination between the surface of a shellbody of the insulating box and the epoxy resin coating is tighter; less nano zirconium oxide is added and can be bonded with epoxy resin to form homogeneously-compounded network type nano coating andthe infiltration of a corrosion medium is effectively prevented, so that the insulating box has excellent corrosion resistance and wear resistance and the bonding strength of the epoxy resin coatingand the surface of the insulating box is also increased; and the epoxy resin coating is prevented from being cracked and becoming fragile.

Description

technical field [0001] The invention relates to the technical field of solid insulated switchgear products, in particular to a coating process for an insulating box of a solid insulated switchgear. Background technique [0002] At present, in the field of power transmission, the solid insulated ring network cabinet is a ring network cabinet that uses solid insulating materials as the main insulating medium. The circuit is single or combined and packaged with a solid insulating medium to form one or several modules with certain functions, which can be recombined or expanded with full insulation and full sealing performance. The surface of the accessible module is coated with conductive or semiconductive The shielding layer can be directly connected to the grounded ring network cabinet. The advantages mainly include that the product is in harmony with the environment, the main circuit is insulated by solid materials, and the three-position switch for isolation and grounding i...
