Abstract

The invention discloses a capacitor flame-retardant insulating oil, which is characterized by comprising the following components by mass: 55-60 parts of castor oil, 22-25 parts of silicone oil, 10-12parts of diphenyl phosphate, 3-5 parts of cresyl diphenyl phosphate, 6-8 parts of phosphate, 8-10 parts of triethanolamine, 8-10 parts of naphthenic acid, 15-20 parts of diphenyl phosphite, 15-18 parts of glycerol, 2-3 parts of carbamide, 4-5 parts of melamine, 7-8 parts of diethyl oxalate, 3-5 parts of butylhydroxytoluene, and 1.5-2 parts of sodium nitrite. The insulating oil has good insulationeffect on the capacitor, and flame-retardant and explosion-proof performance, improves the safety and quality of the capacitor.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a flame-retardant insulating oil for capacitors. Background technique [0002] Oil-immersed capacitor. Cylindrical metal aluminum shell, small size, light weight, excellent electrical performance, low loss, good self-healing characteristics, safe and reliable use. Used in AC power systems, suitable for underground coal mines, railways, aerospace and other places with high safety requirements. [0003] Capacitor insulating oil is usually prepared by adding antioxidants to deeply refined lubricating base oil. The main properties of electrical insulating oil are low temperature performance, oxidation stability and dielectric loss. Low-temperature performance refers to the fluidity necessary for oil to automatically convect in electrical equipment, export heat and cut off arc current instantly under low-temperature conditions. [0004] Existing insulating oil for capacitors has...
