Abstract

The invention provides a high-temperature overload transformer oil, relating to the technical field of lubricating oil production. The high-temperature overload transformer oil is prepared from the following raw materials: 2-4 parts of hydroxy stearin, 2-4 parts of dibutyl phthalate, 3-5 parts of sulfurized calcium alkyl phenate, 2-4 parts of methyl acrylate, 80-90 parts of hydrogenated base oil, 1-3 parts of adsorbent, 2-4 parts of 2,6-di-tert-butyl-para-cresol and 2-4 parts of 2(2H-benzotriazolyl-2-yl)-6-dodecyl-4-methyl phenol. The power industry thermoelectric power generation equipment and material quality inspection indicates that the high-temperature overload transformer oil provided by the invention has the advantages of obvious use effect, high product quality, moderate kinematic viscosity, high flash point, excellent antioxidation and antiaging stability, high cleanness and transparency and favorable gassing property and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of lubricating oil production, in particular to a high-temperature overload transformer oil and a preparation method thereof. Background technique [0002] With the needs of national energy conservation, emission reduction and low-carbon economic construction, reducing the power loss of power lines has become a consensus in the power industry to meet the needs of national energy conservation and environmental protection development; research and development of high temperature overload transformer oil has developed into a trend, but the prepared on the market This type of transformer oil has poor kinematic viscosity, low flash point, and poor oxidation and aging resistance, so it cannot meet good demand in the market. Invention content: [0003] The technical problem to be solved by the present invention is to provide a high-temperature overload transformer oil with good oil quality, simple and reasonable ...
