Shaking Table Test on 145 kV HV Reactor Composite Bushing

Article Preview

Abstract:

As a key component of power transmission and distribution systems, HV reactor bushing made of porcelain have suffered serious damage in previous earthquakes. In order to enhance seismic ability, the new type bushing made of composite material have been used in high seismic fortify-cation intensity projects. The test requirement in this analysis included: the selection of dynamic magnification factor、the selection of excited wave、the control of tolerance between input peak acceleration and output peak acceleration. During the shaking test, the dynamic characteristics, including frequency and damping ratio, and the seismic response of the composite bushing was obtained. Based on the analysis results of the bushing, the judgment of the seismic capacity was achieved.
