Description
Technical field
The present invention relates to chemical field, relate in particular to composite nanoparticle transformer oil that a kind of antirust and insulativity is high 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 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.
Add rust-preventive agent and can prevent that iron core of voltage transformer end face from getting rusty, ensure the quality of transformer oil, and the transformer oil of high insulating property can delay and the contact with moisture time, guarantee has extended work-ing life, once and be corroded oxidation by moisture, the interpolation of rust-preventive agent can be for metallic surface, and the speed of oxidation corrosion is slowed down, and the transformer oil of high insulation rust-proof type is requisite in transformer oil thus.
Along with the maturity all the more of nanotechnology, people start nanotechnology to apply in transformer oil at present, and 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.
