Description

technical field

[0001] The invention relates to a portable multipurpose aerospace cable detector and method, which belong to the field of automatic instruments and meters. Background technique

[0002] In recent years, with the rapid development of aerospace electronic technology, the cables in various aerospace vehicles, detectors and supporting ground equipment are also developing in a complicated and diversified direction. In addition to the complexity of the cable and the number of cores In addition to the substantial increase, various electrical performance requirements are also getting higher and higher.

[0003] Compared with general equipment cables, cables used in aerospace are much harsher, for example, they must be used in working environments such as high altitude, high speed, high acceleration, high temperature and extreme cold, and they must also bear the load of various complex flight actions ; making it easier to produce faults, but the reliability of aerosp...
