Problems solved by technology

If this heat in the coil is not dissipated, it will inevitably cause the heat accumulated in the coil and the iron core to increase and increase the internal temperature of the iron core, which will damage the solid insulation wrapped around the coil

Abstract

The invention discloses insulating and moisture-proof transformer oil containing forsterite powder, which is characterized by being prepared from the following raw materials in parts by weight: 1000-1200 parts of naphthenic base oil, 1-2 parts of aluminum nitride, 0.3-0.5 part of tetradecyl trimethyl ammonium chloride, 0.3-0.5 part of stannous sulfate, 0.3-0.5 part of diethanolamine oleaten, 0.5-1.0 part of crystalline graphite powder, 0.3-0.5 part of polyisobutylene succinimide, 0.2-0.5 part of methyl chloro isothiazolinone, 1-3 parts of forsterite powder and 0.5-1.0 part of auxiliaries. The forsterite powder has advantages of good heat stability, low volume expansion at high temperature, good abrasion resistance, good suspension property, high high-temperature strength and the like; by adopting the powder, the transformer oil can enhance high temperature resistance, abrasion resistance and heat stability of the transformer oil; the transformer oil disclosed by the invention effectively solves problems of the transformer oil which is easy to absorb water and become damp, easy to oxidize and corrode, not high in insulating strength and the like; service lives of a transformer and the transformer oil are prolonged, potential safety hazard is reduced and life quality of people is guaranteed.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to an insulating and moisture-proof transformer oil containing forsterite powder and a preparation method thereof. Background technique [0002] Transformer oil refers to a type of insulating oil used for insulation, arc extinguishing and cooling in oil-filled equipment such as transformers, reactors, transformers, bushings, and oil switches. The insulation function of transformer oil is because it can isolate the live parts of different potentials in electrical equipment, increase the insulation strength, and prevent it from forming a short circuit. During the live operation of the transformer, because the coil has current passing through it, power loss is caused by the resistance. When the current passes through the iron core, the power loss is caused by the magnetic flux of the iron core. The loss of these two parts has been expressed in the form of heat. If this heat in the coil is not...
