摘要:

由于飞机线路系统对开关类器件电磁线圈反向电动势缺少有效的防护,导致引发的安全问题日益严重。借助机上某型继电器烧蚀故障案例,研究了反向电动势产生机理与潜在传播通路,分析了在电磁线圈、触点和电路板等器件上造成的损伤模式。通过仿真模拟和实物测试,制订了针对不同部位的防护措施,给出了防护器件的选型依据,验证了防护效果。研究结论对指导部队外场维护与排故、督促设备厂商产品优化具有一定参考价值。

Abstract:

Due to the lack of effective protection against the reverse electromotive force of switch devices in the aircraft wiring system,the safety issues have become increasiugly serious.Based on the burnout failure case of a certain type of relay on board.The generation mechanism and potential propagation path of the reverse electromotive force are studied.The damage modes to different devices such as coils,contacts,and circuit boards are analyzed.Through simulation and physical testing,the protective measures for different parts are developed.The selection criteria for protective devices are given.The protective effects are verified.The obtained conclusions have certain reference value for guiding the field maintenance and troubleshooting in the military,and urging the equipment manufacturers to optimize their products.

Key words: electromagnetic coil, reverse electromotive force, potential path, damage mode, protection research
