核电高压开关柜抗震性能分析

开关柜的绝缘性能破坏会影响电气设备的正常运行。在核电等特殊领域的高压设备,会受地震影响造成绝缘性破坏继而影响整柜的正常工作,后果十分严重。通过计算和分析,模拟仿真出开关柜整柜在地震作用下的变形有重要意义。文中以Workbench作为仿真平台,采用高性能并行计算机作为计算平台,以振型分解反应谱法为理论基础,对核电1E级F-C交流金属封闭开关设备柜体及主要部件进行了整体抗震分析。评估其整体结构的抗震性能,并且对后续的结构的优化设计提供重要参考。

Anti-seismic Performance Analysis of High Voltage Switchgear for Nuclear Power

The insulation failure of the switchgear will affect the normal operation of the electrical equipment. In the special fields such as nuclear power, high voltage equipment will be affected by earthquake which will cause insulation damage and affect the normal work of the whole switchgear, and the consequences will be very serious. It is important to calculate and simulate the deformation of the cabinet under the action of earthquake. The anti-seismic analysis of the nuclear IE F-C AC metal enclosed switchgear cabinet and main components used the workbench for the simulation platform. The high performance parallel computer is used as the computing platform, and the modal decomposition response spectrum method is used as the theoretical basis. The anti-seismic performance evaluation of its overall structure will provide important reference for the further structural optimization.
