چکیده مقاله:
The key member of an electrical transformer is the high voltage bushings that is mounted on top of the transformer and prepares an electrical connection between the high-voltage lines and the transformer. In the past, strong earthquakes have severely damaged high voltage electrical bushings. This study focuses on modelling existing structures of isolated electrical bushings in order to evaluate the effects of variables that can affect seismic performance and dynamic characteristics. The results of this study demonstrate that three-dimensional seismic isolation systems can improve the seismic performance for a wide range of parameters and can be further effective compared with only horizontal seismic isolation and offer the lowest probabilities of failure for all cases of transformer and isolation system parameters. Therefore, ۳D seismic isolation systems will have a significant impact on reducing the vulnerability of bushings and electrical transformers.
