Abstract

The invention discloses insulating arc suppression nanomaterial modified transformer oil which comprises the following raw materials in parts by weight: 6-8 parts of modified nanomaterial, 1-2 parts of metal deactivator, 2-4 parts of benzyl alcohol, 1-2 parts of magnesium stearate, 1-3 parts of sodium tungstate, 700-800 parts of compound base oil, 7-9 parts of hydroquinone, 0.3-0.5 parts of nitrilotriacetic acid tetrasodium salt, 0.2-0.5 parts of polymaleic anhydride, 0.8-1.2 parts of compound antioxidant, 0.4-0.6 parts of red phosphorus flame retardant and 0.4-0.8 parts of coupling agent. The transformer oil has better insulativity and arc suppression performance, and has better oxidation resistance under a high temperature condition; the nanomaterial is introduced, so that the possibility of oxidation, aging and corrosion of the transformer oil is low, and the stability is improved; and in addition, the transformer oil has good flame retardation, is safe and reliable in raw material component, lower in cost and concise in technology, and has a higher practical value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of power equipment materials, in particular to an insulating arc-extinguishing nanomaterial modified transformer oil and a preparation method thereof. Background technique [0002] Transformer oil is flammable oil, generally does not include synthetic oil, that is, does not include non-fuel oil and high flash point oil. Otherwise, the oil will accumulate [0003] There are two kinds of chlorinated biphenyl (PCB) and fluorine oil, and high flash point oil has silicone oil, alpha oil, beta oil, M oil, polyalphaene, dodecyl benzene, E oil, gamma oil. The ignition point of transformer oil is 165 ℃, while the ignition point of high ignition point oil is above 300 ℃, and no fuel oil will not catch fire. High ignition point oil, also known as flame retardant oil, is mainly used in high ignition point oil-immersed transformers, flame retardant oil on-load tap-changers, capacitors, cables and other occasions. Poly...
