    The invention relates to electrical equipment, namely to materials for impregnation of capacitors.
    Known dielectric fluid · for the impregnation of capacitors based on dichlorodiphenyl [1].
    However, said dielectric fluid has insufficiently high dielectric strength.
    A dielectric liquid composition for impregnating electric capacitors containing an ester is also known [2].
    A disadvantage of the known composition lies in its insufficient electric strength.
    The purpose of the invention is to increase gas absorption.
    This goal is achieved by the fact that in the dielectric liquid composition for impregnation of electric capacitors containing a complex .. ether, an additional one of the materials selected from the group of mono - olefins is introduced, namely decene, dedecene, tetradecene, hexadecene or octadecene.
    and a halogenated liquid, namely benzene, toluene or naphthalene, in the following ratios of ingredients, weight. %: - thirty
    Material from the group of monoolefins 5-20
    Halogenated liquid 10-40 ester up to 100
    In addition, it contains dioctyl phthalate or diphenyl as an ester, and chlorinated benzene as a halogenated liquid.
    Example 1. The composition is prepared in the following ratio of components, weight. %:
    Trichlorobeneol 20
    Tetradecen 10
    Dioctylphthalate Else
    Example 2. The composition is prepared in the following ratio of components, weight. %:
    Chlorinated benzene '10 Decen 10 diphenyl. Rest
    Oil capacitors are impregnated with a dielectric fluid ’composition so that all voids and half-fill are completely filled with dielectric fluid. When voids are left in the system at high electric voltage due to the formation of an ionizing gas, corona discharges can occur in them, as a result of which a dielectric breakdown is possible. High voltage and breakdown of the dielectric of the capacitor in turn. radishes become corona discharge sites.
    Due to the use of trichlorobenzene in the capacitor’s impregnation liquid, the voids at the place of formation of the corona or elevated temperature are filled with perchlorobenzene vapor, since it is a substance that gives high-pressure vapor at a low boiling point and has an electronegative potential, which prevents or minimizing crowns and sparking.
    In the environment around the capacitor, high voltages at high temperatures lead to the release or inversion. hydrogen, which completely destroys the capacitor. Hydrogen forms acid with other elements. · - and water, which also damage the condenser. Hydrogen is easily ionized and undergoes coronation. During coronation, the capacitor dielectric decomposes, gases are rapidly released, and the corona grows. The formation of gas is suppressed by a substance from the moioolefin group (for example, decene).
    While the void formed at the head of the coronation is filled with trichlorobenzene vapor, hydrogen is absorbed by decene.
    The invention provides the creation of a dielectric liquid composition with high absorption capacity ^

    lectrics. The high voltage and breakdown of the capacitor dielectric, in turn, become corona formation. Due to the use of a dielectric liquid for impregnating trichlorobenzene capacitors, voids at the corona or elevated temperature are filled with perlorbenzene vapor, since it is a substance that gives BHCO vapor pressure at a low boiling point, and has an electronegative potential, which prevents or minimizing crowns and sincere. In the environment around the capacitor, high voltages at high temperatures lead to the release or formation of hydrogen, which completely destroys the capacitor. Hydrogen image syeT with other elements acid / and water, which also damage the condenser. Hydrogen is easily ionized and coronated. During the correction, the dielectric of the capacitor decomposes, vigorously releases KIRS gases, and the corona builds up. The formation of gas is suppressed by a substance from the group of momolefins (for example, decene). At the same time, as the void formed in the corona classification is filled with trichlorobenzene vapor, hydrogen is absorbed by decene. The invention provides for the creation of a dielectric liquid composition with enhanced absorption capacity. 1. Dielectric liquid composition for impregnating electrical capacitors, containing an ester, characterized in that, in order to increase the absorption of gas, it additionally contains one of the materials of mono-olefins, namely decene, dedecene, tetradecene, hexadecene or octadecene, and a halogenated liquid, namely benzene, toluene or naphthalene, at. The following ratios of ingredients, weight. %: Material from the group of monoolefins 5-20 Halogenated liquid 10-40 Ester Up to 100. 2. A composition according to claim 1, characterized in that it contains dioctyl phthalate as an ester. 3. The composition of paragraphs. 2 and 3, about t.
