Problems solved by technology

The thermal conductivity of traditional transformer oil is small, which cannot meet the higher and higher heat dissipation requirements. Secondly, the higher and higher voltage levels and miniaturization require that the insulating medium must have higher dielectric strength. Based on this, in order to adapt to the transformer With the development direction of large capacity, ultra-high voltage level and miniaturization, it is imminent to improve the insulation characteristics of traditional transformer oil for long-term operation, and it is imminent to study transformer oil with higher insulation performance and better thermal aging characteristics

Embodiment Construction

[0012] A transformer oil with lubricating effect, made from the following parts by weight (kg) of raw materials: zinc acetylacetonate 4, oleic acid 0.7, ethanol 20, polyimide 2, ethylene diamine 0.2, silane coupling agent KH5700 .4, transformer base oil 1000, polystyrene sulfonic acid 2, stearic acid 0.3, vulcanized oil 20, polyurethane emulsion 3, clay 2.4, graphite 3.4, molybdenum sulfide 3.1, antioxidant 10100.3, poly-n-butyl vinyl ether 0.6.

[0013] The transformer oil with lubricating effect is prepared by the following specific steps:

[0014] (1) Add the clay, graphite and molybdenum sulfide to the ball mill and mix it evenly, then add stearic acid and continue ball milling for 0.5h, mix and stir the zinc acetylacetonate, ethanol and oleic acid, sonicate until the solution is clear, and then add the above prepared The mixed powder is then hydrothermally reacted at 160°C for 20 hours, and the precipitate is dehydrated and dried for later use;

[0015] (2) Heat the polyimide ...

Abstract

The invention discloses transformer oil with a lubricating effect. The transformer oil with the lubricating effect is prepared from, by weight, 4-5 parts of zinc acetylacetonate, 0.7-1 part of oleic acid, 20-24 parts of ethyl alcohol, 2-3 parts of polyimide, 0.2-0.4 part of ethidene diamine, 0.4-0.6 part of silane coupling agent KH570, 1000-1100 parts of transformer base oil, 2-3 parts of polystyrolsulfon acid, 0.3-0.4 part of stearic acid, 20-25 parts of sufurized oil, 3-4 parts of polyurethane emulsion, 2.4-2.6 parts of carclazyte, 3.4-3.8 parts of graphite, 3.1-3.4 parts of molybdenum sulfide, 0.3-0.4 part of antioxidant 1010 and 0.6-0.8 part of polyvinyl butyl ether. The transformer oil with the lubricating effect is simple in preparation method, low in production cost, capable of lubricating and insulating, high in heat conduction, good in oxidation stability, suitable for large-scale production and worthy of promotion.

Description

Technical field [0001] The present invention relates to the technical field of industrial lubricating oil, in particular to a transformer oil with lubricating effect. Background technique [0002] In recent years, power accidents at home and abroad have made people realize that the safety of the power system involves the safety of the entire social and economic life. In the process of power transmission and transformation of the power system, the transformer is one of the most important and critical equipment in the power equipment as the link of power transmission. Its safe and stable operation is related to the stable operation of the entire power grid. Once a serious accident occurs to the transformer running in the system, it will not only cause the destruction of the equipment itself, but also interrupt the power supply of the power grid, which will have a huge impact on the production and life of the society. Especially as the voltage level of the power system is getting h...
