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 dried tangerine peel extract. The transformer vegetable insulating oil is prepared from, by weight, 0.15-0.25 part of nano silica hollow sphere, 1-2 parts of dried tangerine peels, 0.5-1 part of pomegranate peel, 0.05-0.1 part of tea polyphenol, 0.03-0.05 part of antioxidant BHA, 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 diethanol amine, 0.5-1 part of hydroxyl silicone oil, 80-100 parts of refined vegetable oil, 10-15 parts of absolute ethyl alcohol and 0.1-0.15 part of octylphenol polyoxyethylene ether. The vegetable insulating oil has the advantages of being good in long-term oxidization resistance stability and low in viscosity, has anti-bacterial and anti-corrosive properties, is good in sanitation and long in service life and has excellent usability.

Description

technical field [0001] The invention relates to the technical field of transformer insulating oil, in particular to a transformer vegetable insulating oil containing tangerine peel 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 materials. ...
