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

Abstract
The invention discloses high-ignition-point transformer oil. The high-ignition-point transformer oil is prepared from, by weight, 4-5 parts of zinc acetylacetonate, 0.7-1 part of oleic acid, 20-40 parts of ethyl alcohol, 2-3 parts of polyimide, 0.2-0.4 part of ethylene diamine, 0.4-0.6 part of silane coupling agent KH570, 1100-1200 parts of transformer base oil, 2-3 parts of polystyrene sulfonic acid, 0.3-0.4 part of calcium stearate, 0.2-0.3 part of 2,6-butylated hydroxytoluene, 0.2-0.5 part of acrylic resin, 0.4-0.5 part of petroleum sodium sulfonate, 4.3-4.8 parts of tungsten carbide, 3-3.5 parts of aluminium nitride and 4.2-4.5 parts of graphene. The high-ignition-point transformer oil is simple in raw material source, low in production cost, appropriate in ratio and worthy of popularization, the ignition point of the transformer oil is greatly improved, and potential safety hazards are reduced.
Description
technical field [0001] The invention relates to the technical field of industrial lubricating oil, in particular to a transformer oil with high ignition point. 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 in the power system, the transformer, as the link of power transmission, is one of the most important and critical equipment in the power equipment, and 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 becomes ...
