May 5, 2000, wash with water and dry with air, which differs (72) Kim Yen Dar, Serhiy Volodymyrovych Kuks, Khytem, that the cleaning suspension contains a composition Lyuk Volodymyr Vitaliyovych clay-alumina with a weight ratio of 1/6-1/7, (73) SCIENTIFIC-RESEARCH INSTITUTE OF HIGHER TECHNOLOGIES and such, in addition to 2095, is a mass suspension of oil thinners, for example, petroleum solvent. The invention relates to high-voltage technology. The prototype is a method of cleaning the surface and can be used during the maintenance of electro-equipment, which consists in preventive measures for the restoration of the surface to be cleaned. . It is known that the cleaning of the contaminated surface with water and drying with air, and the washing jet is an effective method of restoration, is supplied in a state heated to 40-907С (see. USSR Mo. 1600861 according to M.cl. VOZV3/08 V.D. Yakolyatorov. Vlev, V.I. Savchenko and others). The famous way! cleaning contaminated iso- The disadvantage of the method is the need lations: most heating of the washing solution, ensuring " - compressed air with the addition of ground special safety measures, as well as low dolomite (Y.B. Shur Cleaning of insulators reduces the efficiency of cleaning oily and polluted air. Electrical stations, 1965, no. Mo 10). The disadvantage of this method is that the basis of the invention is the task of enabling micro-damaged surfaces to increase the efficiency and productivity of re-insulating structures; cleaning of contaminated insulation, as well as to reduce co - compressed air with the addition of crushed - costs!. with ice or ice flakes (see as. USSR The solution of the specified task is provided by MO 1686496, M.cl. НО1817/52 / Morozov V.N. Publ. 23.10.1991, Bull. Me 39). Not capable of cleaning contaminated high-voltage - the advantage of the device is the need for isolation, which consists in the fact that a stream of ice water is successively supplied to the cleaning equipment of the installation by a device for the surface; water-based washing suspension, then pro- - with water, jets of high pressure (15-20 atm.), wash with water and dry with air, washing suspension (see as. USSR Mo. 1815676, M.cl. NO1817/52). The composition contains clay-alumina by weight. This method is ineffective when cleaning the ratio of 1/6-1/7, as well as additionally strongly cementing and oily materials up to 2095. oil-based and dirty suspensions. In addition, cleaning the insulation with water products, for example, a petroleum solvent. t requires special spray nozzles, the essence of the proposed method includes hoses, a high-pressure pump; is that the used washing suspension, - with a solution of oxalic acid with the help of a clay-alumina composition, with kapron brushes (Pronin K.N. Znergetik, 1971, falling on the cleaned surface, destroys Mo 7). The disadvantage is low productivity; solid pollution, while not damaging the method, is harmful to human health. the top of the insulation, since the maximum the size of abrasive particles does not exceed 100 μm. The optimal weight ratio of the cast composition to 2095 of the petroleum product diluent in clay-alumina, which achieves a slight dependence on the content of oiliness and the polluted cleaning performance, is in the range of 1/6--1/7 (see Fig. 1). with the help of a sprayer under pressure, the additional content in the suspension is not more than 3.5-4 atm. After removal of a large amount of contaminated (up to 2095 mass! suspension, the surface is washed with water and, if necessary, see Fig. 2) oil thinner (air-dried, "Solvent Neftyanoy") promotes dissolution. - reniyu oily contaminated, thus things in comparison with known methods: the efficiency of cleaning increases. - first of all, as abrasive materials, non-deficient and ecologically weakly cemented, strongly cemented components are used as abrasive materials. dirty and oily, polluted ghosts! in - in the second, insignificant additions to the solvent table. operator and cleaning of contaminated insulation by a mechanized method excludes human contact with aggressive substances harmful to health; It is comparable in terms of speed of cleaning - thirdly, the proposed washing composition of weakly cemented, strongly cemented is universal, it is suitable for removing both thick and oily soiled heavily cemented, as well as soiled, which include hard-to-remove oily compounds; - in quarters, in contrast to the method of cleaning with water, this method allows the use of a relatively low pressure (3.5-4 atm.) applied Contents The application of the proposed method of oiliness cleaning at the enterprises of electrical networks, where systematic preventive measures are taken to restore high-voltage The cleaning method consists of the following: insulation, will allow to significantly reduce the cost of the clay-alumina composition in the ratio 156, for the cleaning of contaminated insulation, water diluted with water in a ratio of 1:5, with the addition and productivity of filling works.
