Abstract：The paper analyzes the reasonable selection of transformer energy efficiency grade in the era background of“peak carbon dioxide emissions”and“carbon neutrality”and under the new situation of promulgation and implementation of new energy efficiency standards. Besides,the performance advantages and characteristics of the semi‑enveloped three‑phase three‑column high‑efficiency and energy‑saving amorphous‑alloy dry‑type transformer are introduced from the aspects of no‑load loss of the transformer,electromagnetic structure design,raw material selection，noise control and process improvement. Finally,the energy‑saving effect of the semi‑enveloped three‑phase three‑column high‑efficiency energy‑saving amorphous alloy dry‑type transformer is compared and analyzed from the aspects of economic and social benefits.
