摘要

作为飞机的重要组成部分，电缆对飞行安全以及飞机性能的实现起着至关重要的作用。针对航空电缆装机后故障难以定位的情况，首先研究了基于 TDR 技术的电缆故障定位方法并分析典型故障波形，然后搭建试验平台，开展电缆短路和断路故障试验，其结果不仅验证了基于 TDR 原理的电缆故障定位方法的正确性，并且得到了有效的电缆典型故障判据及典型故障波形，能够指导机载电缆故障的识别及定位，一定程度上缩短了排故时间。

Abstract

As an important part of aircraft

the cable is crucial to aircraft performance and the flight safety. Because of the difficulty to locate the fault after aerospace-cable been installed in the plane

this paper has researched basic characteristic of the cable and studied the fundamental theory of TDR. Then the experiments are designed and conducted

which not only validates the fault location method based on TDR

but also obtains the effective waveform of typical cable faults and the criterion. These result could provide a guide of fault identification and location

and reduce time.
