The present invention relates to an extra-high voltage direct current wall bushing anti-seismic test device. The device comprises: a support; a wall bushing, wherein a damping device is arranged between the wall bushing and a support; a vibration generator; and an acceleration measurement module, wherein the acceleration measurement module comprises a first accelerometer, a second accelerometer and a third accelerometer, the first accelerometer is configured to measure acceleration data of the wall bushing, the second accelerometer is configured to measure acceleration data of the support, and the third accelerometer is configured to measure acceleration data of the damping device. Through arrangement of the acceleration measurement module, when the vibration generator is started to simulate the earthquake case, the acceleration measurement module measures the acceleration data of the wall bushing, the support and the damping device, the acceleration data are analyzed and processed to obtain the anti-seismic performances of the extra-high voltage direct current wall bushing and the acceleration data of the damping device are analyzed to obtain the influence of the damping device on the anti-seismic reliability so as to comprehensively obtain the anti-seismic test data.
