Description
Technical field
The present invention relates to chemical field, relate in particular to high flame retardant transformer oil of a kind of nitrogen aluminium-antimonous oxide nanoparticle and preparation method thereof.
Background technology
Transformer oil refers to for oil-filled equipments such as transformer, reactor, mutual inductor, sleeve pipe, oil switchs, plays a clasp Y insulation Y oil product of insulation, arc extinguishing and cooling effect.It is because the alive part of different electromotive forces can be kept apart in electric installation that transformer oil plays insulation function, has increased insulation strength, makes it be unlikely to form short circuit.Transformer, in charging operation process, passes through because coil has electric current, because resistance causes power loss, when electric current passes through iron core, because iron core magnetic flux is had an effect, causes power loss, and the form that this two-part loss has all been generated heat shows away.If this dissipation of heat in coil is not gone out, it will inevitably make the heat of coil and iron core inner accumulated cumulative and core interior temperature is raise, thereby can damage the outside coated solid insulation of coil.Transformer oil at this time, because its specific heat is large, by this part heat absorption producing in coil, then makes dissipation of heat out by oily circulation, has ensured the safe operation of equipment.Transformer oil is filled in the space of insulating material, so can play protection iron core and easily oxidized effect of coil block, protection insulating material is not aging.On the on-load voltage regulating switch of oil switch and transformer, contact can produce electric arc while switching.Due to transformer oil good heat conductive performance, and under the high temperature action of electric arc, can divide and touch a large amount of gas, produce larger pressure, thereby improved the arc extinction performance of medium, electric arc is extinguished very soon.
Transformer oil belongs to easy fuel oil, does not generally comprise synthetic oil, does not comprise not fuel oil and high ignition point oil.Not so oil has two kinds of polychlorinated biphenyl (PCB) and fluorocarbon oils, and high ignition point oil has silicone oil, α oil, β oil, M oil, poly-α alkene, dodecylbenzene, E oil, γ oil.The burning-point of transformer oil is 165 DEG C, and the burning-point of high ignition point oil is all more than 300 DEG C, and fuel oil can not catch fire.High ignition point oil claims again flame retardant oil, is mainly used in the occasions such as burning point oil immersed transformer, flame retardant oil load ratio bridging switch, electrical condenser, cable.And the polychlorinated biphenyl of fuel oil, because of carcinogenic poisonous, has not been forbidden, fluorocarbon oil because of the high goods of valency few, seldom use.So the present invention is directed to this situation, disclose a kind of transformer oil preparation method of high flame retardant.
