Embodiment Construction

[0044] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present invention, and are not exhaustive of all the embodiments. And in the case of no conflict, the embodiments and the features in the embodiments of the present invention can be combined with each other.

[0045] The inventor noticed during the invention process that the violent vibration of the engine during operation may easily lead to failures such as loosening of the core crimping point of the electrical connector of the aircraft engine cable, partial strand breakage of the cable, and the like. The characteristics of this kind of fault are more prominent when the engine is running, and the fault information is not clear when it is static, showing obvious int...

Abstract

The invention provides an aircraft engine cable intermittent fault detector and a detection method thereof, and the detector comprises: a case which is provided with a power interface, a detection interface, and a display device; a control module which is arranged in the case and is used for assisting and realizing a detection function; a detection probe accessory, wherein one end of the detectionprobe accessory is connected to the case, the other end of the detection probe accessory provides detection connection, and the detection probe accessory is matched with the control module to achievethe aircraft engine cable intermittent fault detection function. The detector is beneficial to accurately detecting various types of cable intermittent faults of the aircraft engine, and eliminates potential safety hazards of the engine.

Description

technical field [0001] The invention belongs to the technical field of aircraft engine cable fault detection, and mainly relates to an aircraft engine cable intermittent fault detector and a detection method thereof. Background technique [0002] The aircraft engine cable is the connecting channel of the electronic and electrical system of the engine, which is composed of a cable, a shielding layer and an electrical connector. The cable is connected to both ends of the separation surface through the electrical connector and fixed on the engine casing. Severe vibrations during engine operation can easily lead to loosening of the core crimping points of the electrical connector of the aircraft engine cable, partial strand breakage of the cable, and other faults. The characteristics of this kind of fault are more prominent when the engine is running, and the fault information is not clear when it is static, showing obvious intermittent characteristics. [0003] Due to the stro...
