中文摘要:在民用飞机电气线路互联系统(EWIS)设计中,通过物理隔离防止电弧和电磁干扰(EMI)是适航审定的重要内容。以隔离距离为研究对象,基于电磁仿真软件CST,构建多种模型,对不同类型线缆间、不同电信号线路进行了仿真,证明了物理隔离不但是防止电弧产生的有效方式,而且能够极大地降低电磁干扰,同时使用屏蔽线缆和多芯扭绞等防护方法,也是降低电磁干扰的有效措施。
英文摘要:The prevention of arc and electromagnetic interference(EMI) through physical separation is an important issue during the process of electrical wiring interconnection system(EWIS) design for commercial aircraft. Based on CST, this article sets up different types of the electromagnetic interference and simulates the types of cables and the electromagnetic interference between different signals through physical separation space. It is proved that physical separation can not only prevent the arc but also reduce the EMI. Using shielded and multi twisted cable can reduce EMI effectively.
