Abstract
The invention discloses a transformer oil and a preparation method thereof. The transformer oil comprises the following components by weight: 0.05% of an antioxidant, 0.03% of a surfactant, 0.03% of BN nanoparticles and the balance of transformer base oil. The invention has the beneficial effects of substantially improving thermal conductivity and breakdown performance of the transformer oil, and at the same time increasing the dielectric strength of the transformer oil.
Description
Technical field
The present invention relates to a kind of transformer oil and preparation method thereof, relate in particular to transformer oil of a kind of high heat conduction and preparation method thereof.
Background technology
The Main Function of transformer oil is: (1) insulating effect, transformer oil has the insulation strength more much higher than air.Insulating material is immersed in oil, not only can improve insulation strength, but also can avoid the erosion of moisture, (2) thermolysis: the specific heat of transformer oil is large, is commonly used for refrigerant.The heat producing during transformer operation makes to rise near the oily expanded by heating of iron core and winding, and by the convection current up and down of oil, heat sheds by scatterer, guarantees that transformer normally moves.(3) extinguishing arc effect: 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 conductivity, and can divide and touch a large amount of gas under the high temperature action of electric arc, produce larger pressure, thereby improved the arc extinction performance of medium, electric arc is extinguished very soon.The requirement that can not meet product in the market safety and standard improve day by day.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of transformer oil and preparation method thereof.
To achieve these goals, technical scheme of the present invention is: a kind of transformer oil, is comprised of following components by weight percent:
Oxidation inhibitor 0.05%
Tensio-active agent 0.03%
BN nanoparticle 0.03%
Surplus is transformer foundation oil.
Further, described transformer foundation oil is paraffinic base or naphthenic mineral oil.
The preparation method of transformer oil:
1) BN nanoparticle and tensio-active agent are inserted to organic solvent abundant mix and blend;
2) by step 1) in product add in transformer foundation oil, under 40 ℃ of water-baths, be stirred well to organic solvent volatilization completely, then ultrasonic oscillation is 1 hour, standingly obtains the homodisperse stable young of BN nanoparticle;
3) dry dewatering;
4) add carclazyte, under 120 ℃～135 ℃ conditions, high temperature adsorption is 2.5 hours, then exquisite filtration;
5) in step 4) product in add oxidation inhibitor, obtain transformer oil.
The invention has the beneficial effects as follows: significantly improve heat conductivility and the breakdown performance of transformer oil, promoted the insulation strength of transformer oil simultaneously.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
