Problems solved by technology

At the same time, vegetable insulating oil also has disadvantages such as high dielectric loss factor, high kinematic viscosity, prone to oxidation and gelation, and high requirements for transformer operation and maintenance.
CN102682869 effectively reduces the viscosity of vegetable insulating oil by performing transesterification reaction between refined vegetable oil and low-molecular alcohol, but the improvement of long-term oxidation resistance of vegetable insulating oil is limited

Abstract

The invention discloses transformer vegetable insulating oil containing balloonflower root extract, prepared from, by weight, 0.15-0.25 part of nano silicon dioxide hollow beads, 1-2 parts of balloonflower root, 0.5-1 part of root of thinleaf milkwort, 0.05-0.1 part of tea polyphenols, 0.03-0.05 part of antioxidant BHA, 0.1-0.15 part of polyglycerol polyricinoleate, 0.03-0.05 part of tetrabutyl titanate, 0.2-0.4 part of propyl gallate, 0.5-1 part of boric acid, 5-10 parts of diethanolamine, 0.3-0.5 part of squalane, 80-100 parts of refined vegetable oil, and 10-15 parts of absolute ethyl alcohol. The vegetable insulating oil has the advantages of good long-term antioxidant stability, low viscosity, high stability, less proneness to precipitating and deteriorating, good service performance, and long service life.

Description

technical field [0001] The invention relates to the technical field of transformer insulating oil, in particular to a transformer plant insulating oil containing platycodon grandiflorum extract 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 liquid insulating materia...
