Problems solved by technology

The existing domestic transformer oil flash point requirements are basically around 140 degrees, which can basically meet the needs of the normal operation of the transformer, but in special cases, the temperature of the transformer oil may rise to a higher temperature, and the lightning of the existing transformer oil is relatively high Low, so there are potential safety hazards; at the same time, the pour point of conventional transformer oil is around -22 degrees, which cannot meet the operation under low temperature conditions

Abstract

The invention relates to a preparation method of a heat conductive oil used for transformers. The heat conductive oil comprises, by weight, 10 to 20 parts of plant oil, 80 to 90 parts of a base oil, 4 to 6 parts of an imidazolinium compound, 6 to 12 parts of glycerol triacetate, 2 to 4 parts of 2,6-tert-butyl -p-cresol, 1 to 3 parts of an antirust agent, 1 to 3 parts of a surfactant, 1 to 3 parts of a dispersing agent, and 1 to 3 parts of an anti-oxidant. The preparation method comprises following steps: the above ingredients are mixed to be uniform; and an obtained mixture is heated to 50 to 60 DEG C, is stirred, and is cooled. The flash point and the pour point of the transformer heat conductive oil are both higher than that of conventional transformer oil, kinematic viscosity is low, and corrosivity on equipment is low.

Description

technical field [0001] The invention relates to a method for preparing heat-conducting oil for transformers, and belongs to the technical field of transformer oils. Background technique [0002] Transformer is a kind of voltage transformation equipment used in power transmission system, which plays a very important role in power grid system. When the transformer is running, the internal coil will generate a lot of heat. If the heat generated by the coil cannot be dissipated in time, it will affect the normal use of the transformer, and even seriously affect the entire power transmission system; therefore, the current transformers are all There is an oil tank, 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, and then the heat absorbed by the transformer oil is dissipated to the outside through the flat cooling box set on the ...
