摘要
由于对方舱屏蔽性能要求越来越高,电源/信号孔口及转接壁盒的设计和安装成为屏蔽方舱设计和加工的关键环节.总结了电源/信号孔口及转接壁盒的功能作用和对方舱屏蔽性能的影响,阐述了电源/信号孔口及转接壁盒的设计原则,以及通过结构设计消除间隙增强电连续性以保证方舱屏蔽效能满足要求的方法.方舱屏蔽效能测试和系统电磁兼容试验结果表明,电源/信号孔口及转接壁盒的结构设计满足方舱和系统屏蔽性能要求.
Because of increase of the shielding performance of shelter, the design and installation of the power/signal ori- fices and wall box for adapting has become the key of design and process of the shielding shelter. This paper summarizes the function and influence to the shielding performance of shelter of the power/signal orifices and wall box for adapting, and states the design discipline, the structure design method that is used to eliminate clearance and electric connectivity to ensure the shielding performance of the shelter can meet the requirements. The design has passed the test of the shielding effectiveness of the shelter and the experiment of the system electromagnetic compatibility. The results prove that the design can meet the re- quirement of the shielding performance of the shielding shelter and the system.
