电力网络被认为是关键的基础设施。电力公司和电力管理人员对加强其网络的安全性和抗震能力越来越感兴趣。这些网络的重要组成部分是高压变压器。早期在变压器和其他设备上使用隔震系统的研究结果清楚地表明，在水平方向上进行隔震的好处。然而，垂直地面运动通过隔震系统传输时，没有变化，甚至被放大。针对这一问题，本文提出了一种用于电气设备的紧凑、有效、可靠和经济的水平-垂直组合隔震系统的开发和验证。
The electric power network is considered to be critical infrastructure. Electric utility companies and electric power administrators are increasingly interested in strengthening the security and resilience of their networks against earthquakes. Important components of these networks are high-voltage electrical transformers. Earlier studies in the use of seismic isolation systems for electrical transformers and other equipment produced results that clearly show the benefits of seismic isolation in the horizontal direction. However, vertical ground motions were transmitted through the isolation system unchanged or even magnified. In response to this problem, this paper presents the development and validation of a compact, effective, reliable and cost-effective combined horizontal–vertical seismic isolation system for use in electrical equipment.
