Description

Technical Field

[0001] This application relates to the field of carbon fiber cable defect identification technology, and in particular to a method, apparatus and equipment for locating and identifying defects in carbon fiber core cables. Background Technology

[0002] Carbon fiber conductors, due to their advantages such as high capacity and low loss, are frequently used in the capacity expansion and renovation of power transmission corridors. The reliability of crimping carbon fiber conductors is a key concern in engineering. Unlike traditional steel-cored aluminum stranded wire, the crimping technology for carbon fiber is not mature, making it prone to strand breakage and even wire failure, which seriously affects the safety of power transmission. Therefore, the use of carbon fiber conductors is subject to many limitations. Visual inspection, as a clear communication method, is easy for users to understand and suitable for various defect identification.

[0003] X-ray inspection of carbon fiber core conductors can provide visualized images of their defect locations. However, there are several problems in practical applications: to locate the defects using X-rays, X-ray images need to be taken at intervals, resulting in low efficiency; due to the large size and thickness of the carbon fiber core crimping area of ​​the conductor, X-rays have difficulty penetrating this area, making it impossible to produce high-contrast images. When the X-ray machine is slid across the surface of this area, defects are often missed because the contrast between the defect and the normal image is not obvious. Summary of the Invention

[0039] This application provides a method, apparatus, and device for locating and identifying defects in carbon fiber core cables, which solves the technical problems of existing methods for detecting defects in carbon fiber core conductors, such as inability to accurately locate the location of defects, low efficiency, and inability to identify defects.

[0040] Example 1:

[0041] Figure 1 This is a flowchart illustrating the steps of the method for locating and identifying defects in a carbon fiber core cable as described in an embodiment of this application. Figure 2 This is a schematic diagram of the leakage magnetic flux detection device in the method for locating and identifying defects in carbon fiber core cables described in this application embodiment. Figure 3 This is a schematic diagram of the inkjet marking structure of the magnetic flux leakage detection device in the method for locating and identifying defects in carbon fiber core cables described in this application embodiment.

[0042] like Figure 1 As shown in the figure, this application provides a method for locating and identifying defects in carbon fiber core cables, including the following steps:

[0043] S1. The carbon fiber core of the cable is magnetically treated to obtain a magnetic area to be marked.

[0044] It should be noted that in step S1, the carbon fiber core of the cable to be defect-identified is magnetically treated to obtain a cable with the area to be marked.

[0045] In this embodiment of the application, the method for locating and identifying cable defects with carbon fiber core includes: applying magnetic powder, externally coating with a magnetic film, or externally spraying with a magnetic levitation liquid to magnetically treat the carbon fiber core of the cable to obtain a magnetic area to be marked.

[0046] It should be noted that magnetic treatment of the carbon fiber core of the cable can be achieved by adding magnetic powder during the cable manufacturing process, or by coating the surface of the carbon fiber core with a magnetic film or spraying a magnetic levitation liquid on the outside.

[0047] S2. Use a magnetic flux leakage detection device to detect the area to be marked, obtain the defect location and magnetic flux leakage signal, mark the defect location, and obtain the defect identification area corresponding to the area to be marked.

[0048] It should be noted that in step S2, the area to be marked obtained in step S1 is detected using a magnetic flux leakage detection device to find the specific defect configuration and mark it.

[0049] In this embodiment of the application, the use of a magnetic flux leakage detection device to detect the area to be marked and to obtain the defect location includes: using the magnetic sensitive element of the magnetic flux leakage detection device to detect the magnetic flux leakage signal of the area to be marked and to determine the defect location.

[0050] It should be noted that, as Figure 2 As shown, the magnetic flux leakage detection device includes an exciter 406, a magnetic sensing element 407 disposed on the exciter 406, a cable 401 for the area to be marked disposed between the magnetic sensing elements 407, a carbon fiber core 402 disposed on the cable 401, a magnetic film 403 covering the carbon fiber core 402, an aluminum liner tube 402 sleeved over the magnetic core film, and a crimping fitting tube 405 wrapped around the outer surface of the cable 401. In this embodiment, the cable 401 for the area to be marked is first peeled off at the crimping location, and then a high-permeability magnetic film 403 is wrapped over the carbon fiber core 402. The aluminum liner tube 404 and the crimping fitting tube 405 are then sleeved over the magnetic film 403, and the crimping of the area to be marked is completed. Subsequently, a magnetic flux leakage detection device is used for testing. Exciter 206 is used for energization. When the crimping causes a defect in the carbon fiber core 402, the magnetic film 403, due to its close contact and good tracking properties, will produce the same change. The magnetic sensing element 407 captures the magnetic flux leakage signal on the surface of the magnetic film 403, thus determining the defect location. This method for locating and identifying defects in carbon fiber core cables uses a magnetic flux leakage detection device to determine the location of defects at the crimping points of the cable after magnetic treatment, thereby achieving the localization of line defects.

[0051] In this embodiment of the application, the method for locating and identifying cable defects with the carbon fiber core includes: spraying ink onto the defect location using an inkjet printer to mark the defect location, thereby obtaining a defect identification area corresponding to the area to be marked.

[0052] It should be noted that, as Figure 3 As shown, the magnetic flux leakage detection device 201 includes an inkjet printer 202. When the magnetic flux leakage detection device 201 slides on the surface of the carbon fiber core 203 at the cable crimping part, it detects a defect 204 and marks it with inkjet ink at that location.

[0053] S3. Use X-ray inspection equipment to inspect the defect identification area and obtain the inspection image; identify the defect type of the carbon fiber core in the cable based on the inspection image or leakage magnetic signal.

[0054] It should be noted that in step S3, the defect identification area obtained in step S2 is inspected using an X-ray inspection device to obtain an inspection image; then, based on the leakage magnetic signal or inspection image obtained in step S2, the defect type of the cable is identified. X-ray inspection equipment is a relatively mature device in this field and will not be described in detail here. This method for locating and identifying defects in carbon fiber core cables identifies the cable defect type by obtaining an inspection image with inkjet markings. This ensures that the obtained inspection image is definitely an image of the defect, providing accurate data for subsequent image processing and avoiding false images, missed images, and duplicate images, thus improving inspection efficiency.

[0055] This application provides a method for locating and identifying defects in carbon fiber core cables. The method includes: magnetically treating the carbon fiber core of the cable to obtain a magnetically marked area; using a magnetic flux leakage detection device to detect the marked area, obtaining the defect location and magnetic flux leakage signal, and marking the defect location to obtain a defect identification area corresponding to the marked area; using an X-ray detection device to detect the defect identification area, obtaining a detection image; and identifying the defect type of the carbon fiber core in the cable based on the detection image or magnetic flux leakage signal. This method for locating and identifying defects in carbon fiber core cables achieves defect location and identification by magnetically treating the cable, using a magnetic flux leakage detection device to determine and mark the defect location, and finally identifying the defect type through the detection image. This improves the efficiency of cable defect detection and solves the technical problems of existing carbon fiber core conductor defect detection methods, such as inaccurate defect location, low efficiency, and inability to identify defects.

[0056] Figure 4 This is a schematic diagram illustrating the type of defect identification in the cable defect location and identification method with carbon fiber core described in the embodiments of this application. Figure 5 This is a schematic diagram of another type of defect identification structure in the cable defect location and identification method with carbon fiber core described in the embodiments of this application.

[0057] In one embodiment of this application, the defect type of the carbon fiber core in the detected image recognition cable includes:

[0058] If the detected image shows irregular stripes of varying color intensity and length, the defect type of the carbon fiber core in the cable is a fracture defect.

[0059] If the detected image shows lines of uniform color intensity, the defect type of the carbon fiber core in the cable is a low-pressure defect.

[0060] In this embodiment of the application, if the detected image contains irregular stripes of varying color intensity and length, such as Figure 4 The image shows short line segments of varying depths and lengths. This method for locating and identifying defects in carbon fiber core cables uses visual marking to quickly and easily guide engineers in subsequent X-ray inspections. For different marking locations, longer markings increase the X-ray angle, and darker markings increase the X-ray penetration depth. The result is a clear X-ray image that identifies the defect as a fracture defect and determines its extent. Darker fracture defects indicate deeper fractures, and the width of the fracture mark is also considered the fracture width. For ease of understanding, as shown... Figure 4 As shown, there are two defects on the carbon fiber core of the cable, defect 1 and defect 2. The width of defect 1 is greater than that of defect 2, so the final marking width of defect 1 is greater than that of defect 2; the depth of defect 1 is greater than that of defect 2, so the final marking color depth of defect 1 is also greater than that of defect 2.

[0061] In this embodiment, if a line of uniform color intensity appears in the detected image, the length of the marked line is taken as the distance of the underpressure defect. This method for locating and identifying defects in carbon fiber core cables, through visual marking, can quickly and easily guide engineers in subsequent X-ray inspections. By taking an X-ray at the starting point of the underpressure defect and measuring the length of the marked line with a ruler, the severity of the underpressure defect can be determined. The length of the marked line can then be used as the distance to the underpressure defect in the cable. Figure 5 As shown.

[0062] It should be noted that, as Figure 5 As shown, the right end of the carbon fiber core of the cable does not completely fill the crimping fitting. Therefore, a marking line is formed starting from the point of slight crimping and extending to the end of the crimped area. Since the outer surface of the crimping fitting is silver-white, black, indelible marking ink is preferred.

[0063] In one embodiment of this application, identifying the defect type of the carbon fiber core in the cable based on the leakage magnetic field signal includes:

[0064] If the axial component of the leakage magnetic signal shows a symmetrical peak, then the defect type of the carbon fiber core in the cable is a fracture defect.

[0065] If the axial component of the leakage magnetic signal exhibits an asymmetric peak, then the defect type of the carbon fiber core in the cable is a low-pressure defect.

[0066] It should be noted that if the axial component of the magnetic flux leakage signal exhibits a symmetrical peak, the defect type is a fracture defect. The width of the peak in the magnetic flux leakage signal of a fracture defect represents the width of the defect, and the amplitude of the peak represents the depth of the defect. If the axial component of the magnetic flux leakage signal exhibits an asymmetrical peak, the defect type is a low-pressure defect. The peak point is the starting position 'a' of the low-pressure defect, after which the peak signal gradually flattens out until the magnetic flux leakage detection device reaches the end of the crimping part. In this embodiment, when using an inkjet printer for marking, different shapes can be marked on the outer surface of the crimping fitting according to the width and amplitude of the peak signal. The larger the width of the peak signal, the larger the width of the mark; the larger the amplitude of the peak signal, the darker the color depth of the mark. When using an inkjet printer to mark defects, marking can start from the starting point of the magnetic flux leakage signal peak, which is the starting position 'a' of the low-pressure defect, and continue until the end 'b' of the crimping part, ultimately forming a long line segment.

[0070] The magnetic processing module 10 is used to perform magnetic processing on the carbon fiber core of the cable to obtain a magnetic area to be marked.

[0071] The location determination and marking module 20 is used to detect the area to be marked using a magnetic flux leakage detection device, obtain the defect location and magnetic flux leakage signal, mark the defect location, and obtain the defect identification area corresponding to the area to be marked.

[0072] The detection and identification module 30 is used to detect the defect identification area using X-ray detection equipment to obtain a detection image; and to identify the defect type of the carbon fiber core in the cable based on the detection image or leakage magnetic signal.

[0073] In this embodiment of the application, the location determination and marking module 20 is also used to detect the magnetic leakage signal of the area to be marked by the magnetic sensing element of the magnetic leakage detection device, and determine the location of the defect.

[0074] In this embodiment of the application, the detection and identification module 30 is further configured to determine the type of defect in the carbon fiber core of the cable as a fracture defect if the detection image shows irregular stripes of varying color depths and lengths; determine the type of defect in the carbon fiber core of the cable as a low-pressure defect if the detection image shows lines of uniform color depths; determine the type of defect in the carbon fiber core of the cable as a fracture defect if the axial component of the leakage magnetic signal shows a symmetrical peak; and determine the type of defect in the carbon fiber core of the cable as a low-pressure defect if the axial component of the leakage magnetic signal shows an asymmetrical peak.
