Description

TECHNICAL FIELD

[0002] Transformers are widely used in power industry, metallurgy and related industries such as steel, and are indispensable important equipment. Transformers can function as a step-up and step-down, so they can increase voltage and also lower voltage. Voltage can be adjusted, and if it is increased, it can effectively reduce voltage loss. Transformer oil, also known as transformer insulation oil or transformer insulation liquid, is a special oil used for insulation and cooling of transformers. The main function of transformer oil is to provide electrical insulation inside the transformer, prevent electric arc and electric shock, and cool down the various components of the transformer. It can effectively resist the effects of high temperature, high pressure and electric arc, and maintain the normal operation of the transformer. In addition to insulation and cooling, transformer oil also has the function of preventing oxidation and corrosion to prolong the service life of the transformer, and it can also help detect internal faults of the transformer by analyzing the chemical composition and physical properties of the oil to determine the health of the transformer.
