Interactive displacement amplification type wide-width seismic isolation device and method for converter station valve hall

Abstract

The application belongs to power transmission and transformation engineering technical field, and provides an interactive displacement amplification type wide-width isolation device and method for valve hall of converter station. The system comprises a top rubber block, side plates, a transverse energy dissipation device, a connecting rod, a displacement amplifier, a longitudinal damper, a spring piece, a fixing rod and a base. One end of each side plate is connected to two ends of the top rubber block respectively, and the other end of each side plate is inserted into the transverse energy dissipation device to realize transverse displacement through the transverse energy dissipation device. The side surface of the transverse energy dissipation device is fixed on the base with a cavity. The lower part of the transverse energy dissipation device is connected to the bottom surface of the base through the fixing rod. The lower part of the top rubber block is fixed with the connecting rod and forms an integral whole. The lower part of the displacement amplifier is connected to the longitudinal damper. The lower part of the longitudinal damper is an arc surface and is attached to the arc surface of the base. The two sides of the longitudinal damper are respectively attached to a spring piece. The horizontal and vertical vibrations are synchronously and efficiently dissipated.
