Abstract
Использование: в электротехнической промышленности при проведении профилактических работ, ремонте и эксплуатации электротехнического оборудования. Существо: способ заключается в использовании жидких очистителей, воздействующих на поверхности деталей, контактов и электрических соединений с последующим удалением загрязнений и сушкой очищенных поверхностей; очистку оборудования осуществляют в несколько этапов; на первом этапе воздействуют направленной струей диэлектрического очистителя с удельным расходом 0,1 л/кв.м, при этом воздействие струей упомянутого очистителя осуществляют до полного покрытия очистителем поверхностей элементов электрооборудования, затем осуществляют выдержку до 15 мин с достижением размягчённого состояния загрязнений и ослабления их адсорбционной связи с поверхностью элементов электрооборудования; на втором этапе после упомянутой выдержки производят смыв размягченных загрязнений струей смывочной диэлектрической жидкости с удельным расходом до 2,0 л/кв.м и обеспечением перемещения смытых загрязнений на влагопоглощающий материал, размещенный в свободном пространстве электрооборудования; а на заключительном этапе очистки осуществляют удаление влагопоглощающего материала со смытыми загрязнениями для последующей утилизации и производят обдув очищенной поверхности элементов электрооборудования направленной струей воздуха до полного испарения остатков диэлектрического очистителя и смывочной диэлектрической жидкости. На первом этапе используют композицию диэлектрического очистителя, состоящую в мас.% из а) смеси изопарафинов - 35-55, бензола - 30-45, остальное - поверхностно-активные вещества (ПАВ); б) смеси изопарафинов - 35-55, алкильного производного бензола - 30-45, остальное - ПАВ; в) смеси изопарафинов - 10-30, 2-(2-бутоксиэтокси)этилацетата - 30-50, остальное - ПАВ. На втором этапе используют композицию диэлектрического очистителя, состоящую в мас.% из а) смеси изопарафинов - до 95, остальное - ПАВ; б) фторированных углеводородов - до 95, остальное - изопарафин. Воздействие струей смывочной диэлектрической жидкости осуществляют под динамическим давлением до 15 МПа. В качестве ПАВ используют этоксилированный спирт (C9-C11 EO 5,5 или изоС13 EO 7). Очистку осуществляют при функционирующем в штатном режиме электрооборудовании с соблюдением правил электробезопасности, причем проведение указанных работ осуществляют при температуре поверхности элементов электрооборудования не более 80°C, определяемой тепловизором или пирометром. Технический результат заключается в расширении области применения для широкого класса электрооборудования и сокращения времени проведения очистных работ.Usage: in the electrical industry during preventive maintenance, repair and operation of electrical equipment. Substance: the method consists in the use of liquid cleaners acting on the surfaces of parts, contacts and electrical connections, followed by removal of contaminants and drying of the cleaned surfaces; equipment cleaning is carried out in several stages; at the first stage, a directed jet of a dielectric cleaner with a specific flow rate of 0.1 l / m2 is applied, while the action of the jet of the said cleaner is carried out until the cleaner covers the surfaces of electrical equipment, then the exposure is carried out for up to 15 minutes with reaching a softened state of pollution and weakening their adsorption connection with the surface of the elements of electrical equipment; at the second stage, after the mentioned exposure, the softened contaminants are washed off with a jet of a washing dielectric liquid with a specific flow rate of up to 2.0 l / m2 and the movement of the washed off contaminants onto a moisture-absorbing material placed in the free space of electrical equipment is carried out; and at the final stage of cleaning, the moisture-absorbing material with washed off impurities is removed for subsequent disposal and the cleaned surface of the electrical equipment elements is blown with a directed air stream until the remnants of the dielectric cleaner and rinsing dielectric liquid are completely evaporated. At the first stage, a dielectric cleaner composition is used, consisting in wt.% Of a) a mixture of isoparaffins - 35-55, benzene - 30-45, the rest - surfactants; b) a mixture of isoparaffins - 35-55, an alkyl derivative of benzene - 30-45, the rest is a surfactant; c) a mixture of isoparaffins - 10-30, 2- (2-butoxyethoxy) ethyl acetate - 30-50, the rest is a surfactant. At the second stage, a dielectric cleaner composition is used, consisting in wt% of a) a mixture of isoparaffins - up to 95, the rest is a surfactant; b) fluorinated hydrocarbons - up to 95, the rest is isoparaffin. The impact of a jet of flushing dielectric liquid is carried out under dynamic pressure up to 15 MPa. Ethoxylated alcohol (C9-C11 EO 5.5 or isoC13 EO 7) is used as a surfactant. Cleaning is carried out with electrical equipment operating normally in compliance with electrical safety rules, and these works are carried out at a surface temperature of electrical equipment elements not exceeding 80 ° C, determined by a thermal imager or pyrometer. The technical result consists in expanding the field of application for a wide class of electrical equipment and reducing the time for cleaning.
