Abstract
The invention discloses environment-friendly insulation oil for a transformer and a preparing method of the environment-friendly insulation oil and belongs to the technical field of insulation materials. The problems that existing insulation oil is low in flash point, poor in fireproof performance and not environmentally friendly are solved. The environment-friendly insulation oil is prepared from, by weight, 40-50 parts of mixed vegetable oil, 30-70 parts of ethyl alcohol, 0.3 part of citric acid, 0.1 part of edetic acid, 0.2 part of nickel-molybdenum, 3-5 parts of activated clay, 0.5-1 part of esterification reaction catalysts and 3-5 parts of aluminum hydroxide. The preparing method comprises the steps of vegetable oil refining, an esterification reaction and subsequent processing to obtain the finished product. The environment-friendly insulation oil for the transformer has the advantages of being high in ignition point and low in viscosity, and is small in medium loss, good in anti-oxidation stability, long in service life, low in condensation point, good in electric insulation and cooling performance, low in production cost, degradable, regenerative and environmentally friendly, and the preparing method is simple and easy to implement.
Description
Technical field
The present invention relates to a kind of environment protection type transformer transformer oil and preparation method thereof, belong to insulating material field.
Background technology
Transformer insulation oil is a kind of low viscosity oil, be mainly used in the oil-filled electric equipments such as transformer, reactor, mutual inductor, sleeve pipe, oil switch, the Main Function of transformer insulation oil is between transformer winding and winding, winding and iron core and fuel tank, play insulating effect on the one hand; Be when transformer oil is by thermogenesis convection current on the other hand, thermolysis is risen to transformer core and winding.For a long time, transformer insulation oil all uses mineral oil for raw material, its electric insulating quality and cooling performance good, cost is not high yet, but because mineral insulation oil flash point is lower, fire resistance is poor, and biodegradability is poor, pollute the environment during leakage, the shortcoming such as non-renewable makes to be that the transformer oil of raw material more and more receives publicity with vegetables oil.Compared with mineral oil, it is good that department of botany's transformer oil has cooling performance, and weather resistance is high, and flame retardant properties is good, biodegradable, advantages of environment protection.
