In order to calculate the carbon emissions of life cycle of distribution transformers and reduce the carbon emission level of the power grid, this paper proposes a simplified calculation method for the carbon emissions of distribution transformers based on the life cycle assessment method. Emission calculation, comparative analysis of the carbon emission reduction of 400kVA and 630kVA grade 2 energy efficiency distribution transformers compared with grade 3 energy efficiency distribution transformers. The calculation results show that the carbon emissions of distribution transformers in the use stage account for more than 98% of the total carbon emissions of transformers. When the energy efficiency grade of distribution transformers with the same capacity is increased from grade 3 to grade 2, oil-immersed silicon steel core distribution transformers The carbon emissions of the dry-type distribution transformers decreased by about 18%, and the reduction of the dry-type distribution transformers decreased by about 10%.
