N2 - The noise generated by transformers in operation contributes the vast majority of substation noise. In order to study the distribution of transformer core vibration noise, this paper built a vibration acoustic analysis model of 110kV series transformer, carried out the numerical analysis of transformer vibration and noise, and calculated and analyzed the magnetic flux density, core stress and sound field distribution of transformer core. The results show that with the increase of transformer capacity, the magnetic flux density of the iron core of the transformer increases, meanwhile the core stress and distribution of sound field is affected. The maximum total sound pressure level of 63MV.A transformer is 7.8dB higher than that of 40MV.A transformer.
