摘要

本研究系进行供电变压器之隔减震试验，并引入双线性模型与Ｂｏｎｃ－Ｗｅｎ模型作为隔震组件之数学模型，以及以ＡＲＸ模型处理变压器套管之系统识别工作。由试验结果得知所考虑两种隔震组件的隔减震成效可得到验证：整体而言，不论是套管、变压器的加速度、或是变压器基底剪力等，在经过两种隔震组件的作用后，其峰值都可以降低到一半左右，甚或更小。两种隔震组件之数学模型以及套管之ＡＲＸ模型，均能够有效预测隔震后变压器套管系统之受震反应．
In this study, shaking table testing has been conducted to verify the feasibility of seismic base isolation provided to a transformer- bushing system. Experimental results indicate that the con- sidered two seismic base isolation systems were performed very well. Seismic responses of the transformer and bushings were reduced significantly after the adoption of base isolation. Numerical simulation of the seismic response of transformer-bushing system was also conducted and verified.
