Problems solved by technology

[0004] In the prior art, a single mineral oil component is mostly used to produce electrical insulating oil. This single mineral oil has poor fluidity and is easy to precipitate hydrogen; while aromatic hydrocarbons are good in resisting hydrogen precipitation, but the insulating oil is preserved The time is short, and the anti-oxidation performance is poor. After a period of use, the insulating oil is prone to sludge, which greatly reduces the performance of the insulating oil.

Abstract

The invention discloses a method for preparing transformer insulating heat conduction oil. The transformer insulating heat conduction oil comprises the following components in parts by mass: 50-65 parts of mineral base oil, 10-15 parts of castor oil, 5-10 parts of peanut oil, 0.5-3 parts of oil-soluble nano titanium dioxide, 6-12 parts of glycerol triacetate, 0.1-0.2 part of a surfactant, 0.01-0.02 part of an antioxidant, 0.5-1.5 parts of an antistatic agent and 1-3 parts of modified nano boron nitride granules, wherein the base oil is mineral oil of which the kinematic viscosity is 20-35mm<2> / s at 100 DEG C. The transformer insulating heat conduction oil prepared by using the method is good in oil quality, high in oil ignition point, good in insulating property, good in heat conduction property, capable of preventing transformer oil self from generating static electricity to affect the operation of a transformer, moderate in kinematic viscosity, high in flash point, excellent in ,anti-oxidation and anti-aging stability and good in corrosion resistance.

Description

technical field [0001] The invention relates to the field of manufacturing auxiliary materials of power transformers, in particular to a preparation method of transformer insulating heat-conducting oil. Background technique [0002] Transformer is a kind of transformer equipment used in power transmission system and plays a very important role in the power grid system. During the operation of the transformer, the internal coil will generate a lot of heat. If the heat generated by the coil cannot be dissipated in time, the normal use of the transformer will be affected, and even the entire power transmission system will be seriously affected. An oil tank is provided, and the transformer oil is stored in the oil tank. Through the circulation of the transformer oil in the transformer, the heat generated by the coil during the operation of the transformer is absorbed. This completes the process of dissipating the heat generated inside the transformer to the outside world. [0...
