Description
Technical field
The present invention relates to chemical field, relate in particular to a kind of inhibition type transformer oil containing nano-bentonite-aluminium nitride and preparation method thereof.
Background technology
The transformer oil side of being commonly called as canopy oil, light yellow transparent liquid, is a kind of fraction products of oil, its main component is alkane, cycloparaffin series's stable hydrocarbon, the compounds such as aromatic series unsaturated hydrocarbons.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 is at this time because its specific heat is large, and this part heat absorption by producing in coil, then makes dissipation of heat out by oily circulation, has guaranteed 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.
Along with the widespread popularity of nano material, people seek the effect of nano material in transformer oil.Nano modification transformer oil, due to its high-cooling property and unique electric property, is just being subject to paying close attention to more and more widely at present.Nano modification transformer oil in heat conduction, puncture, aging and anti-moisture effects has very large promoter action.Current study hotspot is the selection of nano material.
Aluminium nitride thermal conductivity is good, thermal expansivity is little, electrical insulator, dielectric properties are good, nano-bentonite has good water-absorbent, suspension, stability, thixotropy and dispersiveness, add them to promoted transformer oil in transformer oil thermal conductivity, insulativity, stability and dispersion homogeneity.Because transformer oil is a class stone oil fraction product, there is water-absorbent, so easy oxidized corrosion, the present invention also adds a class inhibiter and delays the speed that transformer oil is corroded.
