Description

technical field [0001] The invention relates to the field of chemistry, in particular to an anti-oxidation and corrosion transformer oil containing various nanoparticles and a preparation method thereof. Background technique [0002] Many high-voltage equipment today use transformer oil as the insulating cooling medium. Transformer oil has a much higher dielectric strength than air. Immersing insulating materials in oil can not only improve the insulation strength, but also prevent moisture erosion. 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 high temperature of the arc, it can to...

Problems solved by technology

After deep oxidation of oil products, oil sludge will be produced. After the oil sludge is precipitated, it will be deposited on the surface of the iron core and coil, causing poor heat transfer and temperature rise of the solid insulating layer, aging and cracking the solid insulating material, and seriously threatening the long-term operation of the transformer.
