Synthetic transformer oil composition

Abstract

The invention discloses a synthetic transformer oil composition which is prepared from the following raw materials in parts by weight: 15-30 parts of paraffin base oil fraction, 5-10 parts of 2,6-di-tert-butyl-para-cresol, 10-20 parts of naphthene base oil, 2-4 parts of n-dodecylbenzene, 1-5 parts of benzotriazole, 2-5 parts of ultraviolet absorbent UV-P, 2-4 parts of coconut oil, 3-6 parts of anhydrous calcium chloride, 2-5 parts of ultraviolet absorbent, 3-7 parts of polybutylvinylether, 4-8 parts of dibutyl phthalate, 6-9 parts of sulfurized calcium alkyl phenate, 5-10 parts of methyl acrylate and 2-8 parts of pentaerythritol. The synthetic transformer oil composition has the advantages of excellent comprehensive properties, low kinematic viscosity, high flash point, excellent and stable oxidation resistance and moderate gassing property, and is capable of inhibiting the transformer oil flow from being electrically charged and enhancing the product quality and work efficiency.

Description

technical field [0001] The invention relates to the technical field of transformer oil, in particular to a synthetic transformer oil composition. 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. 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 ...

Problems solved by technology

[0003] In the prior art, there are many methods for producing transformer oil, among which several published production methods use a single mineral oil component to produce transformer oil, although it can also meet the conventional use of transformer oil, but this production The transformer oil method may be difficult to get rid of the defects caused by the transformer oil produced by a single petroleum component, such as the poor fluidity of a single branched paraffin, and at the same time it is easy to precipitate hydrogen; while aromatic hydrocarbons are good in resisting hydrogen precipitation, but the transformer oil is preserved The time is short, and the anti-oxidation performance is poor. After a period of use, the transformer oil is prone to sludge, which greatly reduces the performance of the transformer oil, etc.; or the production process of the transformer oil is defective, which is easy to pollute the environment.
