高压电气设备动态特性分析

摘要
建立了高压电气设备的计算模型，应用子空间迭代法对几类典型的高压电气设备进行了具体数值分析，比较了刚性节点体系与柔性节点体系力学计算模型之间的模态差异．计算结果表明，高压电气设备的计算模型采用柔性节点体系更符合实际，即计算中应计入瓷套管之间以及设备与支架之间的连接转动刚度，所得结果可为高压电气设备抗震设计提供参考
In this paper,the establishment of high-voltage electrical equipment calculating model is discussed.Some different kinds of typical structure are calculated with the subspace iteration method.It compares the modal differences between the rigid nodal point system and the flexible nodal point system.The analysis shows that the flexible nodal point system is more suitable.The joint rotation stiffness must be considered in the seismic calculation of the high-voltage electrical equipment.
