Abstract

The invention discloses transformer vegetable insulating oil with good heat conducting and radiating performance. The transformer vegetable insulating oil with the good heat conducting and radiating performance is prepared from the following raw materials in parts by weight: 0.15 to 0.25 part of nano-silica hollow spheres, 0.1 to 0.15 part of nano-aluminium nitride, 0.05 to 0.1 part of tea polyphenol, 0.03 to 0.05 part of antioxidant BHA, 3 to 5 parts of dioctyl sebacate, 0.03 to 0.05 part of tetrabutyl titanate, 0.2 to 0.4 part of propyl gallate, 0.5 to 1 part of boric acid, 0.3 to 0.5 part of DiaIk eny Succinimide, 5 to 10 parts of diethanol amine, 1 to 2 parts of pine tar, 80 to 100 parts of refined vegetable oil and 10 to 15 parts of absolute ethyl alcohol. The vegetable insulating oil disclosed by the invention has the characteristics that the long-term anti-oxidation stability is high and the viscosity is low; moreover, the heat conducting property is good; the radiating performance is high; the transformer vegetable insulating oil is high in use performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of transformer insulating oil, in particular to a transformer vegetable insulating oil with good heat conduction and heat dissipation performance and a preparation method thereof. Background technique [0002] As an important liquid insulating medium, insulating oil is widely used in electrical equipment such as transformers. Mineral insulating oil is a liquid mixture composed of various hydrocarbons and is widely used due to its good electrical insulation, cooling properties and low cost. However, the ignition point of mineral insulating oil is low, and the fire safety performance is poor; at the same time, the biodegradation rate is low. If leakage or fire occurs, it will seriously pollute the environment, and it is difficult to meet the needs of high performance and environmental protection. Therefore, the development of new plant insulating oil It has gradually become a hot spot in the research of liqui...
