Nanoparticle transformer oil with good wear resistance and stability, and preparation method thereof

Abstract

The invention discloses a nanoparticle transformer oil with good wear resistance and stability, and a preparation method thereof. The nanoparticle transformer oil is characterized by being prepared from the following raw materials in parts by weight: 1000-1200 parts of naphthenic base oil, 3-5 parts of aluminum nitride, 0.3-0.5 part of bismuth oxide, 0.2-0.5 part of gadolinium chloride, 0.2-0.5 part of urotropine, 0.3-0.5 part of lithium-based grease, 0.3-0.6 part of titanium carbide micropowder, 0.3-0.6 part of polyamide, 0.3-0.6 part of lithium borate, and 0.5-1.0 part of auxiliaries. The added nano aluminum nitride, bismuth oxide, gadolinium chloride and lithium borate particles have excellent dielectric property, high stability, good heat-conducting property, and small thermal expansion coefficient, and can greatly improve the insulating, arc extinction, stability and radiation performance of transformer oil; the added titanium carbide micropowder and polyamide have good wear resistance; and due to the added auxiliaries, the transformer oil is clarified, the oxidization property is reduced, the stability is enhanced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a transformer oil with good wear resistance and stable nanoparticles and a preparation method thereof. Background technique [0002] Transformer oil, commonly known as square shed oil, is a light yellow transparent liquid that is a fractionation product of petroleum. Its main components are compounds such as alkanes, naphthenic saturated hydrocarbons, and aromatic unsaturated hydrocarbons. The relative density is 0.895. Freezing point <-45 ℃. The heat generated during the operation of the transformer causes the oil close to the iron core and winding to expand and rise. Through the convection of the oil up and down, the heat is dissipated through the radiator to ensure the normal operation of the transformer. On oil circuit breakers and on-load tap taps for transformers, arcing occurs when the contacts switch. Due to the good thermal conductivity of transformer oil, and under the hig...

Problems solved by technology

Oil products will inevitably come into contact with oxygen during long-term use, which will cause the oil to age and produce acidic substances or sludge. However, acidic substances will corrode copper, iron and other metal materials used in equipment to form metal salts, which will accelerate the aging of oil products. , the generated sludge sticks to the coil and insulating parts, causing blockage of the channel, accelerating the aging of solid insulating materials, seriously affecting heat dissipation, and causing partial overheating of the coil in the transformer, resulting in accidents
