000019108 520__ $$2eng$$aAimed to the dynamic response study of large Ultra-High-Voltage (UHV) converter transformer, the 3-D FEM analysis model of a actual isolated ±800kV converter transformer was built considering oil-solid interaction. Then the natural vibration characteristics, dynamic response rules and vulnerable points of isolated ±800kV converter transformer were analyzed based on LS-DYNA software. Then the shaking table test of the experimental model which of scale is 1/4 to pure model was carried out. Simulation and testing results show that interaction of oil and wall of active part has obvious amplification effect on dynamic response of converter transformer, and the oil-solid interaction should be considered in the analysis of natural vibration characteristics and seismic response for converter transformer. The vulnerable points of sleeve are at the root and middle of sleeve and the max tensile and press stress at these points appear in turn. The sleeves of converter transformer have large displacement under earthquake, therefore, electric wire at the top of sleeve should have enough reserved length.
