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.
Abstract:
The calculation model of high-voltage electrical equipment is established, and the specific numerical analysis of several typical high-voltage electrical equipment is carried out by applying the subspace iterative method, and the modal differences between the mechanical calculation model of rigid node system and flexible node system are compared. The calculation results show that the calculation model of high-voltage electrical equipment is more in line with the flexible node system. That is, the rotational stiffness of the connection between the porcelain casing and between the equipment and the bracket should be included in the calculation, and the results obtained can provide a reference for the seismic design of high-voltage electrical equipment.
