描述了电弧的概念、特点、产生机理及危害。从民用飞机电气线路互联系统（EWIS）布线安装设计的角度出发，深入分析了线束电弧产生的主要原因，即导线绝缘层的物理破坏和老化。在借鉴国际通用技术规范和型号研制经验的基础上，针对可能导致电弧产生的因素，提出了具体的电弧防护措施，有助于在布线安装设计初期，最大程度上减小电弧产生的隐患。同时，针对民用飞机设计单位构建线束电弧防护设计体系提出相应建议，为线束设计人员提供参考。

Described the arc of the concept, features, mechanism and hazards. From the perspective of commercial aircraft EWIS wiring instal ation design, analyzed the main reason of arc generating for harness—wire insulation physical damage and aging. Based on the learning from international general technical specification and project researching experience, explained the arc protection method for factors that could cause arcing, it can provide a reference for harness designer and reduce the possibility of arc generating to the maximum extent in the early EWIS wiring instal ation design. At the same time, put forward three suggestions on how to construct the harness of arc protection design system for aircraft design units.
