【摘要】 油浸式变压器是由多种材料组成的复杂结构。本文对油浸式高压变压器建立了较为精确的有限元模型,考虑了各组件之间相互作用的影响。对该设备进行了动力性能和地震响应分析以及易损性分析。分析结果表明,大型高压变压器在地震中的首要破坏模式为瓷套破坏,其地震响应的离散度较高。易损性分析得到设备的地震易损性曲线,可直接应用于电力系统的抗震分析。更多还原

【Abstract】 It is difficult to analyse the seismic response of the transformers,because the structure of the transformers is more complex.An accurate finite element model of a high-voltage transformer is established.The model considers the interaction between the components.The seismic responses of the high-voltage transformers are computed by the model.The numerical studies of the seiemic respronses of the equipment show that porcelain bushings is the most vulnerable compenent in strong earthquakes.Seismic fragility curves of the transformers are presented for estimating the seismic damage of the transformers.更多还原
