Fluorination liquid composition and application thereof in transformer

Abstract

The invention discloses a fluorination liquid composition and application thereof in a transformer. The fluorinated liquid composition is prepared from hexafluoropropylene dimer, hexafluoropropylene trimer, perfluorohexanone, perfluoroheptane, perfluorooctane, perfluoropentane, perfluorohexane, perfluorotripropylamine, perfluorotributylamine, perfluorotriamylamine, perfluoro-N-methylmorpholine, perfluorocyclic ether, perfluoropropyl methyl ether, perfluorobutyl methyl ether and perfluorobutyl ethyl ether. Any four of the perfluoro-2-methyl pentane-3-methoxy ether, the perfluoro-2-methyl hexane-3-ethoxy ether and the C8 cyclic ether mixture are respectively marked as a first component, a second component, a third component and a fourth component. Compared with traditional transformer oil, the fluorination liquid composition has better fluidity, thermal conductivity, heat dissipation, insulativity, high boiling point, low freezing point, low density and the like, and due to the advantages of environmental friendliness, oxidation resistance, low acid value and the like, the fluorination liquid composition is applied to a transformer, the defects of an existing transformer medium are reduced, and the service life of the transformer is prolonged.

Description

technical field [0001] The invention relates to the technical field of transformer media, in particular to a fluorinated liquid composition and its application in transformers. Background technique [0002] Power transformers are the core equipment for power generation and transformation in industrial and mining enterprises and power systems. Normal operation or not is related to the safety and economic benefits of enterprises. The occurrence of transformer equipment accidents will also affect or interfere with the stable operation of the national economy. As a traditional transformer medium, transformer oil is used in transformer equipment. It has good dielectric and thermal conductivity, low freezing point and other excellent properties. It mainly plays the role of insulation, heat dissipation and arc suppression. However, transformer oil is generally obtained from mineral oil or petroleum, and its defects such as flammability, easy aging, and serious environmental polluti...

Problems solved by technology

Although the gas medium is conducive to the development of transformers towards high voltage and large capacity, and insoluble oil has the advantages of no flash point and no ignition point, due to the common heat dissipation problems of gas medium, α oil, β oil, γ oil and other insoluble oils have viscosity. Defects such as high temperature, poor fluidity, and poor heat dissipation are important factors that hinder its large-scale entry into the market
