Problems solved by technology

[0004] Since the base oil of transformer oil is generally refined by hydrogenation process, under the action of sunlight, ultraviolet light, magnetic field, and heat energy, the base oil after hydrogenation can undergo a series of photo-oxidation and thermal oxidation condensation polymerization reactions, releasing Hydrogen, acetylene, methane, ethane, ethylene, carbon monoxide, carbon dioxide and other gases, with turbidity and precipitation, lead to abnormal operation of the transformer, thus affecting the reliability of the power grid

Abstract

The invention discloses oxidation-resistant transformer oil which comprises the following components in percentage by weight: 0.2-1.5 percent of 2,6-butylated hydroxytoluene, 0.02 per mill-0.5 percent of 2-(2'-hydroxy-5'-methyl phenyl) benzotriazole, 5-200ppm of benzotriazole and the balance of transformer base oil. According to the transformer oil, the heat oxidation resistance and photooxidation resisance of the transformer oil are improved, the preparation process is simple and convenient, the production cost can be greatly reduced, and the product quality and working efficiency are improved.

Description

technical field [0001] The invention relates to a transformer oil, in particular to an oxidation-resistant transformer oil. Background technique [0002] Transformer oil is a fractionation product of petroleum. It is a mineral oil obtained through distillation and refining of natural petroleum. A mixture of liquid natural hydrocarbons with good cooling properties. The main components of transformer oil are alkanes, naphthenic saturated hydrocarbons, aromatic unsaturated hydrocarbons and other compounds. [0003] The main functions of transformer oil include: (1) Insulation function: Transformer oil has a much higher dielectric strength than air. The insulating material is soaked in oil, which not only improves the insulation strength, but also protects against moisture. (2) Heat dissipation effect: Transformer oil has a large specific heat and is often used as a coolant. The heat generated during the operation of the transformer causes the oil close to the iron core and ...
