000018421 520__ $$2eng$$aTo investigate seismic performance of 220kV transformer-bushing systems, a small transformer tank was designed and manufactured, and equipped with 2 real 252 kV porcelain bushings. Shaking table tests on the transformer-bushing system were conducted. Modal properties were acquired through white-noise scanning tests. Seismic performance of the transformer-bushing system under Wenchuan earthquake ground motion excitation was also acquired. The tests show that the transformer tank and turret significantly amplify acceleration at the flanges of the bushings, whereas displacement, strain responses are acceptable. Rocking vibration of the bushing-turret assembly induced by flexibility and out-of-plane bending vibration of tank wall markedly magnifies bushing seismic responses. The earthquake responses of the bushings remarkably couples with rocking vibration of the turret.
