摘要
本文采用玻璃-金属封接技术完成一种电气贯穿组件的结构设计,根据工艺特点针对导体、玻璃及外壳进行材料选型,采用有限元方法建立组件数值计算模型,基于此模型计算出组件在正常运行时的温度场分布,判定材料选择的合理性。同时,选取部分样件密封结构开展环境及力学类试验,验证了组件密封结构的可靠性;针对组件整体开展了热老化及辐照老化试验,试验验证了组件在长期高温、高压及高辐照剂量使用环境下具有良好的适应性。
In this paper,the glass-metal sealing technology is used to complete the structural design of an electrical penetration assembly,and the material selection is carried out for the conductor,glass and shell according to the process characteristics.The component numerical calculation model is established by the finite element method,based on this model to calculate the components during normal operation of the temperature field distribution,and determine the rationality of material selection.At the same time,some sealing structure samples were selected to carry out environmental and mechanical tests to verify the reliability of the sealing structure.The thermal aging and irradiation aging tests are carried out for the whole component,and the test results are satisfactory.The component has good adaptability to the environment of long-term high temperature,high pressure and high irradiation dose.
