Problems solved by technology

Although this kind of high-voltage live cleaning agent has the characteristics of high insulation, it only cleans the insulators running online. The insulators belong to primary equipment. When cleaning, it is only required to ensure electrical insulation. There are no requirements for flammability, corrosion, toxicity, etc. Moreover, the components contained in this high-voltage charged cleaning agent are oil-based cleaning materials, which will form an oil film after cleaning. If it is applied to high-precision instruments such as secondary equipment, it will easily cause oily secondary pollution. The physical and electrical characteristics of secondary equipment can cause many safety issues
So far, the research on the safe cleaning of secondary equipment during live operation is still blank, and how to realize safe and efficient live cleaning of secondary equipment is still a difficult problem to break through

Embodiment 1

[0024] A method for electrified cleaning of secondary equipment is described below by taking the cleaning of a power distribution cabinet as an example.

[0025] In the live operation of the power distribution cabinet, a mixture of 78.5 grams of surfactants, 13.2 grams of cleaning aids, 6.7 grams of antirust and corrosion inhibitors, 1.6 grams of defoamers and 0.8 grams of enzyme preparations is used as a charged cleaning agent. The power distribution cabinet is spray cleaned. Among them, the surfactant is a mixture of 25.4 grams of fatty alcohol polyoxyethylene ether, 21.3 grams of triethanolamine oleate, 18.5 grams of alkyl phosphoric acid ester, and 13.3 grams of amide phosphoric acid ester. Wetting, solubilizing and emulsifying abilities; the cleaning aid is sodium hydroxide, which has a synergistic effect with surfactants, strengthens the decontamination ability, prevents precipitation, clarifies the solution, prevents freezing, and prevents corrosion; the antirust and co...

Embodiment 2

[0029] Use the mixture of 78.5 gram surfactants, 13.2 gram cleaning aids, 6.7 gram antirust and corrosion inhibitors, 1.6 gram defoamers and 0.8 gram enzyme preparation as charged cleaning agent, wherein, surfactant is 25.4 gram fatty alcohol polyoxygen A mixture of vinyl ether, 21.3 grams of triethanolamine oleate, 18.5 grams of alkyl phosphate, and 13.3 grams of amide phosphate, the cleaning aid is sodium hydroxide, the antirust and corrosion inhibitor is sodium tripolyphosphate, and the defoamer is 0.9 grams The mixture of organosiloxane and 0.7 g of nonylphenol polyoxyethylene ether, and the enzyme preparation is alkaline protease, which can be prepared by mixing evenly. Then, test the pH of the water extract of the charged cleaning agent, corrosion to metals, corrosion to plastics, flash point, flammability, residual content, ODS content, volatility, insulation resistance, the tests are listed in Table 1 result.

Abstract

The invention relates to a method for cleaning, dedusting and descaling secondary equipment, in particular to a method for realizing live cleaning of secondary equipment. During live operation of the secondary equipment, live cleaning agents are used for flushing or spray-washing the secondary equipment through a cleaning device, and a recovery device is used for recovering dirt. On the premise that the secondary equipment is not powered off and does not stop running, various dirt such as dust, greasy dirt, moisture, salt, metal dust, carbon stains and the like on the surface and in a deep layer of the equipment can be safely and efficiently cleaned, high safety of high insulation, non-toxicity, non-combustibility, corrosion resistance and the like is achieved, and the gap of safely cleaning the secondary equipment in live operation in the prior art is filled. The method makes a great breakthrough, and has fine application prospect in the field of secondary equipment maintenance.

Description

technical field [0001] The invention relates to a method for cleaning secondary equipment, in particular to a method for safely cleaning the secondary equipment under electrified operation. Background technique [0002] Electrical equipment refers to the general designation of generators, transformers, power lines, circuit breakers and other equipment in the power system, mainly including primary equipment and secondary equipment. Primary equipment refers to electrical equipment that is directly used to produce and use electric energy and has a higher voltage than secondary equipment, mainly including generators (motors), transformers, circuit breakers, insulators, isolating switches, automatic switches, contactors, knife switches, and busbars , Transmission lines, power cables, reactors, motors, etc. Secondary equipment refers to auxiliary equipment for monitoring, measuring, controlling, protecting, and adjusting primary equipment, including measuring meters, such as volt...
