Technical Field

[0002] Traditional methods for detecting misalignment in cable accessory assembly mainly rely on manual visual inspection or simple mechanical measurement.

[0003] In addition, existing technologies such as X-ray inspection and ultrasonic testing can be used to detect cable assembly misalignment defects by measuring optical and acoustic characteristics. However, existing detection methods suffer from problems such as complex operation, high cost, and limited application scenarios. While X-ray inspection can scan and image the cable under test to determine whether the cable assembly is misaligned, this method exposes workers to significant radiation, affecting their health, and cannot be used in the field, requiring laboratory sampling. Ultrasonic testing is mainly used to detect ultrasonic signals generated by partial discharge during cable assembly defects. It is sensitive to partial discharge signals, but the response signal in the ultrasonic range is not obvious for the characteristics of assembly misalignment itself.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] Please see Figure 1 This is a flowchart illustrating the steps of a cable accessory assembly misalignment detection method according to the first embodiment of this application, thereby accurately reflecting the assembly status of the cable accessories. The method includes: Step 101: Perform electromagnetic wave reflection tests on different test points of the cable accessories, and obtain the electromagnetic wave incident signal intensity and electromagnetic wave reflected signal intensity at each test point during the electromagnetic wave reflection test. Step 102: Obtain the electromagnetic wave signal reflectivity at each test point based on the electromagnetic wave incident signal intensity and the electromagnetic wave reflected signal intensity; Step 103: Obtain the first peak time corresponding to the target electromagnetic wave reflected signal intensity; the target electromagnetic wave reflected signal intensity is the electromagnetic wave reflected signal intensity with the largest signal intensity; Step 104: Perform assembly inspection on the cable accessories based on the electromagnetic wave signal reflectivity and the first peak time to determine whether misalignment has occurred in the assembly of the cable accessories.

[0026] Specifically, to accurately assess the assembly quality of cable accessories, this embodiment employs electromagnetic wave reflection testing technology to systematically inspect different test points of the cable accessories. During the test, electromagnetic waves are first emitted to each test point using specialized equipment, and the incident electromagnetic wave signal intensity at each test point is accurately recorded. Subsequently, the intensity of the reflected signal generated after the electromagnetic wave encounters the internal structure of the cable accessory is captured and measured. Based on the incident and reflected signal intensity data, the electromagnetic wave signal reflectivity at each test point is obtained by calculating the ratio of the reflected signal intensity to the incident signal intensity. This reflectivity is a key indicator for assessing the integrity of the internal structure of the cable accessory. Further, the target electromagnetic wave reflection signal with the highest signal intensity is selected from all reflected signals, and its corresponding first peak time is determined. The first peak time reflects the time it takes for the electromagnetic wave to propagate and return inside the cable accessory, and is closely related to the assembly state of the cable accessory. Combining the electromagnetic wave signal reflectivity and the first peak time, the assembly quality of the cable accessory is judged using a preset algorithm or standard. If both the reflectivity and peak time meet the preset range, the assembly is determined to be within acceptable limits; if there is a significant deviation, the assembly is determined to be misaligned.

[0027] The method in this embodiment, through electromagnetic wave reflection testing, can quickly detect different test points of cable accessories, obtain the intensity of incident and reflected signals, calculate the reflectivity, and obtain the first peak time of the target reflected signal intensity. This greatly shortens the detection time, improves the detection efficiency, and avoids the efficiency problems caused by slow manual operation or cumbersome mechanical measurement. This method is based on objective electromagnetic wave signal data for analysis, is not affected by human factors, and the detection results are more accurate and reliable. The electromagnetic wave reflection testing method in this embodiment is relatively simple to operate, requires no complex equipment, poses no radiation hazard to workers, and can be carried out on-site without site restrictions, reducing detection costs and application difficulty. At the same time, by analyzing the electromagnetic wave signal reflectivity and the first peak time, this method can accurately reflect the assembly status of cable accessories, effectively detect assembly misalignment defects, and make up for the shortcomings of insufficient accuracy of ultrasonic testing.

[0028] In a specific embodiment, the assembly detection of the cable accessory based on the electromagnetic wave signal reflectivity and the first peak time to determine whether the cable accessory assembly has been misaligned includes: obtaining a reflectivity difference based on the electromagnetic wave signal reflectivity and a preset standard signal reflectivity; the preset standard signal reflectivity is the electromagnetic wave signal reflectivity of the cable accessory that is not misaligned; obtaining a first assembly quality index of the cable accessory based on the reflectivity difference and the first peak time; the assembly quality index is used to characterize the non-misalignment rate of the cable accessory assembly; and performing assembly detection of the cable accessory based on the first assembly quality index and a first preset threshold to determine whether the cable accessory assembly has been misaligned.

[0029] Specifically, the electromagnetic wave signal reflectivity at each test point is compared with the preset standard signal reflectivity. The preset standard signal reflectivity is based on the electromagnetic wave signal reflectivity measured under the same test conditions for properly assembled cable accessories, such as... Figure 2 The reflectivity curve of the correctly installed stress cone serves as a benchmark for determining whether the assembly quality meets standards. A schematic diagram of the reflectivity curve of the stress cone to be tested is shown below. Figure 2 The curve of the stress cone misalignment installation. Figure 2 In the test, the number of sampling points for the reflectivity curves of correctly installed stress cones and incorrectly installed stress cones is the same. Therefore, the difference between the two is calculated based on the different reflectivities corresponding to the same sampling points, resulting in a reflectivity difference value. This difference value can intuitively reflect the degree of deviation between the test point and the acceptable state. The curve corresponding to the peak occurrence time of the stress cone to be tested is shown in the figure. Figure 3 The curve showing the peak time of stress cone misalignment during installation is used to extract different values ​​for the first peak time. Combining the reflectivity difference with the first peak time, a comprehensive evaluation model is constructed to calculate the first assembly quality index of the cable accessory. The first peak time, reflecting the propagation characteristics of electromagnetic waves within the cable accessory, influences the assembly quality index along with the reflectivity difference. This index, through a specific algorithm, quantifies and integrates the reflectivity difference and the first peak time, numerically representing the non-misalignment rate of the cable accessory assembly. A higher index indicates that the assembly quality is closer to the qualified standard. The calculated first assembly quality index is compared with a first preset threshold. This first preset threshold, set based on actual application requirements and historical data statistical analysis, is used to distinguish between non-misalignment and misalignment. Specifically, if the first assembly quality index is less than or equal to the first preset threshold, the cable accessory is judged to be misaligned; if it is greater than the first preset threshold, it is judged to be non-misaligned.

[0030] In a specific embodiment, the first assembly quality index is obtained using the following formula:

[0031] in, This is the first assembly quality index. As the first preset weight, As the second preset weight, For the first i The difference in reflectance at each test point This refers to the first peak time.

[0032] In a specific embodiment, the first preset weight and the second preset weight are obtained using the following formula:

[0033] in, As the first preset weight, As the second preset weight, The preset temperature sensitivity coefficient for cable accessories. The actual surface temperature of the cable accessory. This is the preset reference temperature.

[0034] Specifically, the preset temperature sensitivity coefficient of the cable accessories is determined experimentally beforehand and is used to characterize the sensitivity of the cable accessories' electromagnetic wave reflection characteristics to temperature changes under different temperature environments. Since temperature changes can affect the electromagnetic properties of the cable accessory materials, thus affecting electromagnetic wave reflection, this coefficient is crucial in calculating the assembly quality index. A high-precision temperature sensor is used to obtain the actual surface temperature of the cable accessories. The temperature sensor should be placed in a position that accurately reflects the overall temperature condition of the cable accessories to ensure the reliability of the measurement data. When calculating the first assembly quality index, the reflectivity difference, the first peak time, the preset temperature sensitivity coefficient, and the actual surface temperature are all taken into consideration. Specifically, the reflectivity difference is first corrected for temperature based on the preset temperature sensitivity coefficient and the actual surface temperature to eliminate the influence of temperature on the reflectivity difference. The corrected reflectivity difference more accurately reflects the assembly state of the cable accessories under standard temperature conditions. By combining the corrected reflectivity difference with the first peak time, a preset algorithm model is used for calculation. This algorithm model comprehensively considers the influence weights of the reflectivity difference and the first peak time on the assembly quality, as well as the temperature-corrected data, and finally derives the first assembly quality index. This index can more comprehensively and accurately characterize the misalignment rate of cable accessories in assembly, providing a reliable basis for subsequent assembly quality inspection results.

[0035] In a specific embodiment, the method further includes: acquiring the reflectivity of an abnormal electromagnetic wave signal; the abnormal electromagnetic wave signal reflectivity being the reflectivity of an electromagnetic wave signal exceeding a second preset threshold; acquiring the second peak time corresponding to the abnormal electromagnetic wave signal reflectivity; obtaining a second assembly quality index of the cable accessory based on the abnormal electromagnetic wave signal reflectivity and the second peak time; then, the assembly detection of the cable accessory based on the first assembly quality index and the first preset threshold to determine whether misalignment has occurred in the assembly of the cable accessory includes: performing assembly detection of the cable accessory based on the first assembly quality index, the second assembly quality index, and the first preset threshold to determine whether misalignment has occurred in the assembly of the cable accessory. For example, selecting... Figure 2 In the reflection corresponding to the misaligned installation of the medium-stress cone, sampling points with a reflectivity greater than 72% were selected from sampling points 0.0-0.4 as abnormal points, and sampling points with a reflectivity greater than 50% were selected from sampling points 0.4-1.0 as abnormal points. The reflectivity corresponding to the abnormal points is the reflectivity of the abnormal electromagnetic wave signal. According to Figure 2 The sampling point corresponding to the reflectivity of the abnormal electromagnetic wave signal is in Figure 3 The second peak occurrence time is read from the peak value, and the second assembly quality index of the cable accessories is obtained based on the total reflectivity of all abnormal electromagnetic wave signals and the total second peak time.

[0036] Specifically, electromagnetic wave reflection testing equipment is used to monitor and record the electromagnetic wave signal reflectivity at each test point in real time. Signals with reflectivity exceeding a second preset threshold are defined as abnormal electromagnetic wave signal reflectivity. The second preset threshold is set based on a large amount of qualified cable accessory test data and experience; exceeding this threshold may indicate local defects or assembly abnormalities in the cable accessory. For each abnormal electromagnetic wave signal reflectivity, its corresponding second peak time is obtained. The second peak time reflects the time characteristics of the abnormal signal propagating and returning within the cable accessory, and is closely related to the location and type of the abnormality. Subsequently, based on the abnormal electromagnetic wave signal reflectivity and the second peak time, a specific algorithm model is used to select the maximum value to calculate the second assembly quality index. This index focuses on the impact of abnormal signals on the assembly quality of cable accessories and is an effective supplement to the first assembly quality index.

[0037] In a specific embodiment, the second assembly quality index is obtained using the following formula:

[0038] in, This is the second assembly quality index. As the third preset weight, As the fourth preset weight, The reflectivity of the abnormal electromagnetic wave signal, The second preset threshold, It is the difference between the second peak time and the first peak time.

[0039] In a specific embodiment, the assembly inspection of the cable accessory based on the first assembly quality index, the second assembly quality index, and the first preset threshold to determine whether the cable accessory is misaligned includes: weighting and summing the first assembly quality index and the second assembly quality index to obtain a third assembly quality index; comparing the third assembly quality index with the first preset threshold; if the third assembly quality index is greater than the first preset threshold, the assembly quality inspection result is that the assembly is not misaligned, otherwise it is misaligned.

[0040] Specifically, the first and second assembly quality indices are weighted and summed. These two indices reflect the assembly quality of cable accessories from different dimensions. The first assembly quality index is calculated based on the reflectivity difference of conventional test points, the first peak time, and temperature correction, focusing on the overall assembly assessment. The second assembly quality index is calculated based on the reflectivity of abnormal electromagnetic wave signals and their corresponding second peak time, emphasizing the impact of local anomalies on assembly quality. Based on actual testing needs and experience, reasonable weighting coefficients are assigned to the two indices, with the sum of the weighting coefficients being 1. The two indices are then integrated through weighted summation to obtain the third assembly quality index. This index combines overall and local assembly quality information, more accurately representing the actual assembly condition of cable accessories. The calculated third assembly quality index is then compared with a first preset threshold. The first preset threshold, determined through extensive experiments and real-world case analysis, is used to distinguish between proper assembly and misaligned assembly. If the third assembly quality index is greater than the first preset threshold, it indicates that the assembly quality of the cable accessories meets the requirements, and the test result is determined to be that the assembly is not misaligned. If the third assembly quality index is less than or equal to the first preset threshold, it indicates that there is a problem with the assembly quality, and there may be misalignment. The test result is determined to be misalignment. By using this weighted summation and comparison method, the information from the first and second assembly quality indices is fully utilized, improving the accuracy and reliability of the assembly quality test results and providing strong support for the quality control and subsequent use of cable accessories.

[0041] In a specific embodiment, please refer to Figure 4This is a schematic diagram of a cable accessory assembly misalignment detection system according to a second embodiment of this application. The system includes: a signal strength acquisition module 201, a signal reflectivity acquisition module 202, a peak time acquisition module 203, and a detection module 204. The signal strength acquisition module 201 is used to perform electromagnetic wave reflection tests on different test points of the cable accessory, and acquire the electromagnetic wave incident signal strength and electromagnetic wave reflected signal strength at each test point. The signal reflectivity acquisition module 202 is used to obtain the electromagnetic wave signal reflectivity of each test point based on the electromagnetic wave incident signal strength and the electromagnetic wave reflected signal strength. The peak time acquisition module 203 is used to acquire the first peak time corresponding to the target electromagnetic wave reflected signal strength. The target electromagnetic wave reflected signal strength is the electromagnetic wave reflected signal strength with the largest signal strength. The detection module 204 is used to perform assembly detection on the cable accessory based on the electromagnetic wave signal reflectivity and the first peak time to determine whether the cable accessory assembly has been misaligned.

[0042] The system in this embodiment can quickly detect different test points of cable accessories through electromagnetic wave reflection testing, obtain the intensity of incident and reflected signals and calculate the reflectivity, as well as obtain the first peak time of the target reflected signal intensity, which greatly shortens the detection time and improves the detection efficiency. It avoids the efficiency problems caused by slow manual operation or cumbersome mechanical measurement.
