TRANSFORMER OIL - Uses and synthesis methods

classification

transformer oil is divided into mineral transformer oil and synthetic transformer oil. 1. Mineral transformer oil: It is refined from natural petroleum processing. Petroleum (commonly known as crude oil) can be distilled under constant pressure and reduced pressure to obtain various fractions. Mineral transformer oil is obtained by fractionation of petroleum at 260~340 ℃ and then refining. Its composition includes alkanes, cycloalkanes and aromatic hydrocarbons. Alkane-based petroleum is called paraffin-based crude oil, and petroleum containing more cycloalkanes is called cycloalkyl crude oil. In order to improve the antioxidant stability of transformer oil, antioxidant additives can be added. 2. Synthetic transformer oil: It is an insulating oil produced by a synthetic method. It is superior to mineral transformer oil in some characteristics, such as polychlorinated biphenyls, silicone oil (polydimethylsiloxane), Trityl alcohol propane ester and quiso tetraol ester have flame retardant or non-combustible characteristics, and alkylbenzene has gas evolution resistance. Classification

features

1. Physical properties

Transformer oil has the basic characteristics of high dielectric strength, low viscosity, high flash point temperature, good low temperature characteristics and oxidation resistance. The properties of transformer oil are represented by physical, chemical and electrical characteristics such as appearance, chromaticity, specific gravity, viscosity, flash point, freezing point, interfacial tension, moisture, oxidation stability, acid value, sludge, corrosive sulfur, dielectric loss factor, power frequency and impact breakdown voltage, gas extraction and other physical, chemical and electrical characteristics. 2. chemical properties

Chemical reaction is a threat to the quality of transformer oil, especially acidic substances are more dangerous to it. Acidic substances will produce moisture, and this moisture may cause transformer oil to deteriorate, resulting in transformer The performance of the oil changes, thereby reducing or even disappearing the protective effect of the transformer. Transformer oil has an insulating effect. If the chemical reaction causes its moisture to be injected into the transformer oil, it will erode the insulating material in the transformer parts, causing conductivity and leakage. In serious cases, it may cause the transformer to produce sparks and explosions. Secondly, the chemical reaction process or after the reaction will produce many impurities, these impurities will also affect the quality of transformer oil, so that the transformer oil can not normally dissipate heat on the transformer, resulting in the transformer temperature is too high and the consequences of damage.
