Abstract

Disclosed corrosion-inhibiting transformer oil added with a red phosphorus fire retardant is characterized by being prepared from the following raw materials in parts by weight: 1000-1500 parts of cycloalkyl base oil, 3-5 parts of aluminium nitride, 0.3-0.5 parts of 2,6-dimethylmorfolin, 0.2-0.5 parts of acrylic resin, 0.2-0.5 parts of a red phosphorus fire retardant, 0.3-0.5 parts of dodecenylsuccinic anhydride, 0.2-0.5 parts of benzotriazole, 0.2-0.5 parts of sodium lactate, 0.2-0.4 parts of chlorobutanol, and 0.4-0.8 parts of an auxiliary agent. By adding the red phosphorus fire retardant into the transformer oil, safety hidden trouble caused by inflammable property of transformer oil is effectively solved. Added dodecenylsuccinic anhydride helps to delay the oxidation corrosion speed of the transformer oil. The added auxiliary agent enables the transformer oil to be clarified, free of impurities, reduced in oxidation property, enhanced in stability, and prolonged in service life.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a corrosion-inhibiting transformer oil added with a red phosphorus flame retardant and a preparation method thereof. Background technique [0002] The electrical strength of transformer oil is 4-7 times higher than that of air, so using it as an insulating medium can greatly reduce the volume of the transformer. Transformer oil has high electrical strength. When the oil is broken down, the insulation can be restored without leaving a permanent discharge channel, so transformer oil has been widely used. Transformer oil has high insulation strength. It is mainly used as insulating medium in electrical equipment, and because of its large specific heat capacity, it is also used as cooling medium. It is used as arc-extinguishing medium and cooling in circuit breakers, on-load tap-changers and starting compensators. contact function. In high-voltage cables, oil plays the role of filling and ...
