| 摘 要： | 为研究地震作用下变电站软母线连接电气设备间的动力相互作用,进行实际设备与软母线连接体系的地震模拟振动台试验。通过对设备间无软母线以及连接不同松弛度软母线的设备动力响应的比较分析,得出软母线对电气设备的影响规律,验证了理论计算模型的正确性。在软母线松弛度较大时,软母线连接电气设备体系的响应与单体设备的响应差别不大。在软母线松弛度较小时,软母线与电气设备间产生了非常明显的相互作用,且这种相互作用在地震动幅值较小时,会对设备产生约束作用;在地震动幅值较大时,由于剧烈的动力效应,母线内会产生较大的张力,对设备产生不利的影响。在进行变电站软母线连接设备的抗震设计中,需要考虑强震作用下母线的影响。

| Abstract: | In order to study the dynamic interaction of substation equipment interconnected by flexible buses subjected to earthquakes,a shake table test on a full scale model was carried out.After comparing the seismic behavior of the independent equipment with that of the equipment interconnected by the flexible buses of different slackness,the dynamic interaction mechanism of the coupling system was given and the theoretical model for analyzing the seismic interaction was also verified.When the slackness of the fle... |
