Abstract
Description
Technical Field
[0001] This application relates to the field of rail vehicle technology, specifically to a cable structure with cable wear monitoring function. Background Technology
[0002] With the rapid development of high-speed rail vehicle technology in China, the types and quantities of onboard equipment are gradually increasing. As the main medium for power transmission, cables are also increasing in type and quantity. In the confined space of the carriage, the cable wiring environment is relatively complex, making the monitoring of their operating status particularly important.
[0003] When a train is running, vibrations can easily cause cables to wear down when they come into contact with sharp edges. This is especially true in high-risk locations where manual inspection and regular maintenance are difficult or where protection is inadequate. Even with braided mesh protection, the lack of sharp edge protection can easily wear down the cable insulation layer, causing the core to come into contact with the support and ground, which can lead to relay failures, circuit breaker tripping, and other malfunctions.
[0004] Therefore, to meet practical needs, a cable structure with cable wear monitoring function is provided. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a cable structure with cable wear monitoring function. By winding a sensor between the cable bundle and the cable protection tube, the wear condition of the cable is monitored, so as to cooperate with other equipment to provide fault early warning, improve monitoring convenience, and effectively ensure the normal use of the cable.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0007] This application provides a cable structure with cable wear monitoring function, the cable structure comprising:
[0008] A cable bundle consisting of multiple cables;
[0009] Cable protection tube wrapped around the outside of the cable bundle;
[0010] A wound sensor is disposed around the outside of the cable bundle, located between the cable bundle and the cable protection tube; wherein...
[0011] The winding sensor includes:
[0012] A wound cable is wound around the outside of the cable bundle and located between the cable bundle and the cable protection tube, wherein the winding cable runs in the same direction as the length of the cable bundle.
[0013] Multiple sensors are spaced apart on the wound cable.
[0014] Compared with the prior art, the advantages of this application are:
[0015] This application monitors cable wear by incorporating a winding sensor between the cable bundle and the cable protection pipe. This allows for fault warnings in conjunction with other equipment, improving monitoring convenience and effectively ensuring the normal use of the cable. Attached Figure Description

[0030] The winding sensor 3 includes:
[0031] A wound cable 30 is wound around the outside of the cable bundle 1 and located between the cable bundle 1 and the cable protection tube 2. The winding cable 30 has the same orientation in the length direction as the cable bundle 1.
[0032] Multiple sensors 31 are spaced apart on the wound cable 30.
[0033] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.
[0034] See Figures 1-3 As shown in the figure, this application embodiment provides a cable structure with cable wear monitoring function, the cable structure including:
