Problems solved by technology

When transformer oil is in normal operation, the oil temperature is 60-80°C. When it is overloaded, the oil temperature is higher. At the same time, it is inevitable to contact with oxygen and metal catalysts such as copper and iron during long-term operation to cause oxidation reactions. Decreased oil stability against oxidation

Abstract

The invention provides an additive combination for improving the oxidation stability of transformer oil. The additive combination is prepared from, by weight, 100-150 parts of jojoba oil, 10-15 parts of 2-methyl-benzotriazole, 20-30 parts of thiodipropionic acid diester, 5-10 parts of 9,10-acridanyl, 1-3 parts of parlkaline calcium sulfonate and 5-10 parts of dialkyl anilino cyclohexane. The synthesized additive combination for the transformer oil has the good heat oxidation resistance and photooxidation resistance, is suitable for various types of transformer oil such as paraffin-based transformer oil, naphthenic base transformer oil and mixed transformer oil, can be in compound use with other various transfer oil additives, and can achieve ideal oxidation resisting effects with very small dosage.

Description

technical field [0001] The invention relates to transformer oil, in particular to an additive for improving the oxidation stability of transformer oil. Background technique [0002] Transformer oil is a kind of insulating oil product, which is mainly used in transformers and their supporting equipment as insulation and cooling medium and transformer operation monitoring carrier. The insulation strength of transformer oil is higher than that of air. After the transformer is filled with oil, the internal parts of the transformer can maintain good insulation, which increases the insulation strength of the transformer. During the operation of the transformer, the heat exchange is completed through the circulating flow of the transformer oil, and then enters the inside of the transformer oil tank to form the oil circulation and achieve a good heat dissipation effect. Transformer oil is also used as a carrier to monitor changes in transformer operating conditions during operation...
