TRANSFORMER OIL OXIDATION RETARDATION METHOD

FIELD: power engineering. ! SUBSTANCE: present invention relates to the field of energy, in particular to the used in oil-filled electrical equipment transformer oil production. Application scope: the transformer oils production. Transformer oil oxidation slowing down method, which includes the antioxidant additive addition thereto at the production stage, breaking off the oxidation chains and acting as the free radicals deactivator, according to the present method, as the antioxidant additive cyclohexyldecyl sulfide at a concentration of 0.5 % is used containing sulfur with the free pair of electrons, which trap the oil free radicals. ! EFFECT: increase in the containing cyclohexyldecyl sulphide (C16H32S) as the antioxidant additive transformer oil quality, by the following parameters: the amount of absorbed oxygen, the dielectric losses angle tangent, the water content, the amount of precipitate, water-soluble acids, the acid number. ! 1 cl, 1 tbl
