Изобретение бтноситсй к области технического обслуживани электрических машин.The invention relates to the maintenance of electric machines.
В процессе работы электрических машин переменного и посто нного тока в атмосфере, hAe имейтс пары нефтепродуктов (топлива, смазочного масла) и пыль, в том числе угольна пыль от щетОк, происходит загр знение ьбмотоК) коллекторов и ш,еточного аппарата. В результате этого происходит ухудшение работы электромашин, их дополнительный нагрев и недопустимое понижение сопротивлени изол ции.During the operation of electric machines of alternating and direct current in the atmosphere, hAe has a pair of petroleum products (fuels, lubricating oil) and dust, including coal dust from brushes, contamination of the collectors and w of the current apparatus occurs. As a result, the deterioration of the operation of electric machines, their additional heating and unacceptable lowering of the insulation resistance occur.
Известно использование углеводородных растворителей - керосиновой фракции, дизельного топлива или уайт-спирита дл очистки от масл ных и углеродистых загр знений. Однако при очистке электрических машин указанные растворители только частично раствор ют поверхностный слой масла, не проника вглубь отложений и обмотки изол ции статора и ротора электромашины. Моюш .а эффективность этих растворителей составл ет всего 20%, т. е. вно недостаточна. Кроме того, данные растворители опасны в пожарном отношении и токсичны.It is known to use hydrocarbon solvents - kerosene fraction, diesel fuel or white spirit for cleaning from oil and carbonaceous contaminants. However, when cleaning electrical machines, these solvents only partially dissolve the surface layer of oil, which does not penetrate deep into the deposits and windings of the insulation of the stator and rotor of the electric machine. Motion. The effectiveness of these solvents is only 20%, i.e., it is obviously insufficient. In addition, these solvents are fire hazardous and toxic.
Предлагают в состав моюгцего средства в качестве углеводородного растворител вводить обессмоленную нефт ную фракцию, выкипаюшую в пределах ПО-200°С, и дополнительно вводить фторСодержаш,йй галоидуглеводород .It is proposed to introduce into the composition of the mougent as a hydrocarbon solvent, a resin-free petroleum fraction that has boiled away within a PO-200 ° C, and additionally to introduce fluorine-containing hydrocarbons.
Оптимальным соотношением компонентов вл етс следующее, вес.%: обессмоленна нефт на The optimum ratio of components is the following, wt.%: Oil-free oil

фторсодерл ащий галоидуглеводород25-10 Состав, содержащий 75-90 вес.% обессмоленной нефт ной фракции и фреон-113 в количестве 25-10 вес.%, имеет температуру вспышки выше 100-120°С, что вполне обеспечивает взрыво- и пожаробезоиасность, как процесса очистки, так и последующего включеии электромашин, кроме того, он нетоксичен . На .аемой поверхности жндкость не оставл ет п тен, т. е. нолиостью испар етс . Проверка действи данного состава на различные изол ционные материалы (эмаль, ироволоку, битумные пропитки и др.) показала , что он не нарушает изол цию, металличе ские части двигател не корроднруют.fluorosoderyl halohydrocarbon25-10 Composition containing 75-90 wt.% of oil-free oil fraction and freon-113 in the amount of 25-10 wt.%, has a flash point above 100-120 ° С, which completely ensures explosion and fire safety, as the cleaning process, and the subsequent inclusion of electric machines, in addition, it is non-toxic. On the surface, the surface does not leave a stain, i.e., the vapor content evaporates. Checking the effect of this composition on various insulating materials (enamel, fiber, impregnation of bitumen, etc.) showed that it does not break the insulation, the metal parts of the engine do not corrode.
Дл очистки состав обычно нанос т па очищаемую поверхность кистью или иульверизацией , после очистки смесь легко уда.ч ют сжатым воздухом, что исключает необходимость гор чей сушки обмотки. Моющее действие состава составл ет 100% по сравнению с 20%, достигаемым при очистке известными углеводородными растворител ми.For cleaning, the composition is usually applied to the surface to be cleaned with a brush or spray and, after cleaning, the mixture is easily removed with compressed air, which eliminates the need for hot drying of the winding. The detergency of the composition is 100% compared to 20% achieved when cleaning with known hydrocarbon solvents.
