| 摘 要： | 高压电瓷型电气设备的地震易损性极高,而抗震研究较少.选取一种在500 kV线路中常用的瓷柱式FS6断路器,利用有限元分析软件ANSYS对其进行自振特性分析;并用反应谱法对其进行抗震性能分析.结果表明:该设备强度可抵抗8度地震,9度时不满足强度要求.还提出了模型建立过程中应注意的问题,并提出了几点展望.为电瓷型电气设备的减隔震设计提供理论参考.

| Abstract: | High voltage electric equipment with bushings are subject to earthquake damage,however,not much related research is available.In this paper,ANSYS was used to analyze the free vibration characteristics of a kind of SF6 circuit breakers with bushings which are often used in 500 kV lines,and the circuit breaker's anti-seismic performance was analyzed with the response spectrum method.The results showed that the equipment can resist the strength of 8 degree earthquakes.Problems that should be noted during model... |
