摘　　要：核电设备的抗震分析和抗震试验验证是为了确保设备在发生安全停堆地震(SSE)时能够保证结构完整性和可运行性。核电设备抗震性能在核电建设中至关重要,本文在分析1E级K3类380V低压配电盘抗震设计的基础上,结合IEEE、IEC、RCC-E等标准,引入基于迭代拟合设计反应谱的方法,提出采用液压试验台模拟地震工况的抗震试验方法。试验表明:该方法能有效验证配电盘的抗震性能,为设备结构优化提供设计思路,同时,为核电站建设提供质量保证。The seismic design and testing of nuclear power equipment is to ensure that the equipment main⁃tains structural integrity and operability in the event of safe shutdown earthquake(SSE).The seismic performance of nuclear power equipment is crucial in the construction of nuclear power.Based on the analysis of the seismic design of the 1E class K3380 V low-voltage switchboard,combined with the IEEE,IEC,RCC-E and other standards,the iterative fitting specification is introduced through the seismic analysis of the switchboard under the safe shutdown seismic load.The seismic test method using hydraulic test bed to simulate seismic condition is proposed.The test results show that the method can effectively test the seismic resistance of the switchboard,provide design ideas for equipment structure optimization,and provide quality assurance for nuclear power plant construction.
