The invention provides a transformer oil additive, a preparation method and application of the transformer oil additive in transformer oil gas adsorption, and belongs to the technical field of adsorption of dissolved gas in transformer oil. The transformer oil additive is activated carbon loaded with monatomic nano-palladium and is prepared by mixing and stirring a Na2PdCl4 aqueous solution, a PVA solution and a NaBH4 solution to obtain palladium sol, acidifying the palladium sol with concentrated sulfuric acid, then adding activated carbon, stirring, filtering, washing, drying and calcining to obtain the transformer oil additive, the loading capacity of the monatomic nano palladium on the activated carbon is 1-2wt%. The insulating fluid is prepared by doping the additive into the transformer oil, so that the adsorption of H2 in the transformer oil can be improved, the partial discharge fault can be eliminated, and the additive has important significance for relieving the transformer fault and ensuring the sa
