The invention provides an installation corrosion protection structure of an aircraft large-current grounding wire. The protection structure comprises an aircraft body structure, an electric wire connector connected with an electric wire, and an adapter bracket used for connecting the aircraft body structure and the electric wire connector; the adapter bracket and the aircraft body structure are made of different metal materials, the adapter bracket is connected with the aircraft body structure and/or the wire joint through a connecting piece, and the contact surface between the adapter bracket and the aircraft body structure and/or the wire joint is polished; a sealant is sprayed on the periphery of a contact gap between the adapter bracket and the wire joint and/or the aircraft body structure, and the sealant uniformly permeates into the contact gap. According to the installation corrosion protection structure of the aircraft large-current grounding wire, grounding installation work of an EWIS system on an aircraft can have good electrical performance in a severe environment area, and installation corrosion can be effectively prevented.

    本申请提供了一种飞机大电流接地电线的安装腐蚀防护结构,所述防护结构包括:飞机机体结构;连接电线的电线接头;以及用于连接飞机机体结构与电线接头的转接支架;其中,转接支架与飞机机体结构为不同的金属材料,转接支架与飞机机体结构和/或电线接头之间通过连接件连接,且转接支架与飞机机体结构和/或电线接头之间的接触面打磨处理,在转接支架与电线接头和/或飞机机体结构的接触缝隙周围喷涂有密封剂,所述密封剂均匀的渗入接触缝隙内部。本发明提供的飞机大电流接地电线的安装腐蚀防护结构可以使飞机上的例如EWIS系统的接地安装工作在环境恶劣区域具有良好的电气性能,可以有效的防止安装腐蚀。
