【摘要】 本文以沈阳高压开关厂５５０ｋＶ高压开关为研究对象，简单介绍了分析方法和计算机程序（ＳｕｐｅｒＳＡＰ９１），建立了计算模型，提出了具体的分析步骤，给出了该设备在静力和地震作用下瓷柱根部处的内力和应力，分析了该产品的抗震安全性。虽然本文的计算分析是以具体的高压开关设备为对象，但文中提出的方法、步骤和结构分析通用程序，同样适用于相关设备的抗震计算，对高压电气设备的抗震分析具有参考价值。更多还原

【Abstract】 In this paper,seismic performance of a 550kV high voltage switchgear madein Shenyang High Voltage Switchgear Factory is studied.The calculation model for the switchgearis established and the analytical procedure by use of computer program Super SAP 91 aregiven.The displacements and stresses on the porcelain column base under static and earthquakeeffect are calculated and the seismic safety of the product is estimated.Since the method,procedure and computer program can be used generally,the paper has the referential valuein the seismic analysis for other high voltage electrical equipments.更多还原
