Embodiment 1

[0022] A sensing coating for gas leakage of GIS equipment, characterized in that,

[0023] Made from the following raw materials in parts by weight: 30 parts of silicone-modified epoxy acrylic acid, 0.2 parts of cobalt oxide crystals, 2 parts of water, 3 parts of cellulose nanofibrils, 60 parts of bismuth vanadate, 20 parts of polyvinyl alcohol, oxidized 18 parts of aluminum, 12 parts of sea foam powder, 20 parts of talc powder, 20 parts of mica powder, 6 parts of silicone coupling agent, 20 parts of xylene, 2 parts of dispersant, 1 part of anti-sedimentation agent, 3 parts of defoamer, Bi 2 WO 6 0.2 parts.

[0024] If a leak occurs, the leak point will produce a green spot. When the coating thickness is 0.2cm, the discoloration function starts to fade at 18 months.

Embodiment 2

[0026] A sensing coating for gas leakage of GIS equipment, characterized in that,

[0027] Made from the following raw materials in parts by weight: 50 parts of silicone-modified epoxy acrylic acid, 0.2 parts of cobalt oxide crystals, 2 parts of water, 5 parts of cellulose nanofibrils, 60 parts of bismuth vanadate, 30 parts of polyvinyl alcohol, oxidized 18 parts of aluminum, 12 parts of sea foam powder, 30 parts of talc powder, 20 parts of mica powder, 10 parts of silicone coupling agent, 30 parts of xylene, 4 parts of dispersant, 3 parts of anti-settling agent, 5 parts of defoamer, Bi 2 WO 6 0.2 parts.

[0028] If a leak occurs, the leak point will produce a green spot. When the coating thickness was 0.2cm, the discoloration function began to fade at 19 months.

Embodiment 3

[0030] A sensing coating for gas leakage of GIS equipment, characterized in that,

[0031] Made from the following raw materials in parts by weight: 40 parts of silicone-modified epoxy acrylic acid, 0.2 parts of cobalt oxide crystals, 2 parts of water, 4 parts of cellulose nanofibrils, 60 parts of bismuth vanadate, 28 parts of polyvinyl alcohol, oxidized 18 parts of aluminum, 12 parts of sea foam powder, 26 parts of talc powder, 20 parts of mica powder, 8 parts of silicone coupling agent, 26 parts of xylene, 3 parts of dispersant, 2 parts of anti-settling agent, 4 parts of defoamer, Bi 2 WO 6 0.2 parts.

[0032] If a leak occurs, the leak point will produce a green spot. When the coating thickness was 0.2cm, the discoloration function began to fade at 23 months.

Description

technical field [0001] The invention relates to a sensing coating for gas leakage of GIS equipment, which belongs to the technical field of coatings. Background technique [0002] With the increasingly widespread use of sulfur hexafluoride (SF6) gas insulation medium in high-voltage electrical equipment, the maintenance work of gas leakage is becoming more and more heavy, and the leakage of SF6 gas has become one of the important factors affecting the operation safety of GIS electrical equipment. There are many reasons for the leakage of SF6 gas. Summarized from the production, installation and use of sulfur hexafluoride equipment, the causes of leakage can be divided into selection, processing and assembly of equipment production materials, on-site installation, equipment design defects and sealing. In terms of material aging, damage and use, the existing leakage detection technology not only has a huge workload, but also cannot find the location of the leakage point in the...
