Abstract
China is an earthquake-prone country. In recent years, Wenchuan earthquake and other earthquakes have caused serious damage to power facilities. As the most important electrical equipment in UHV substations, transformers are facing great threat of earthquake disasters. Currently, seismic evaluation of UHV transformers does not consider soil-structure interaction, which is not conducive to fine seismic design and evaluation of UHV transformers. Based on the structural features of the UHV transformer equipment, the seismic evaluation method of the UHV transformer with soil-structure interaction is proposed in this paper, which provides a basis for the seismic performance evaluation of the UHV transformer.
