核电站电气贯穿件的应力评定及试验验证

Stress Evaluation and Test Verification of Electrical Penetration Assemblies in Nuclear Power Plants

应用ANSYS有限元软件对电气贯穿件在各种工况下的力学性能进行分析,通过动态特性试验对有限元分析法进行验证。在此基础上根据RCC-M规范对设备进行应力分析与评定,为安全壳电气贯穿件的设计提供依据。

ANSYS finite element software was used to analyze the mechanical behavior of electric penetration assemblies under various working conditions, and the analysis results were subsequently verified by dynamic performance tests. On this basis, stress analysis and evaluation were carried out on relevant assemblies according to the RCC-M code, which may serve as a reference for the design of electrical penetration assemblies in containment structures of nuclear power plants.
