Description

Technical Field

[0001] This invention relates to the field of composite sleeve repair technology, specifically providing a method and system for evaluating and repairing the skirt of a composite sleeve. Background Technology

[0002] Composite bushings, as key insulating components of power equipment, have their skirts exposed to the complex outdoor environment for extended periods. They are prone to aging due to factors such as ultraviolet radiation, fluctuating temperature and humidity, and contaminant adhesion, manifesting as decreased hydrophobicity, surface powdering, and cracking. These aging problems significantly reduce the bushing's insulation performance, shorten its service life, and increase the risks of flashover and surface discharge, seriously threatening the safe and stable operation of the power system.

[0003] Due to the high cost of replacing composite bushings, the aging of composite bushing skirts is typically addressed through on-site manual cleaning and application of repair coatings to extend their service life. However, existing on-site repair technologies have many limitations and cannot meet the high-quality operation and maintenance requirements of power systems. First, aging assessment relies on manual judgment, lacking standardized and automated testing methods. Maintenance personnel usually rely on visual inspection of the skirt surface or manual simple water-repellent tests, which cannot accurately distinguish different aging levels, leading to either "over-" or "under-" repair measures. Second, the repair process has low automation, mainly relying on manual operation, resulting in high labor intensity, low work efficiency, and difficulty in guaranteeing repair quality. Traditional composite bushing skirt maintenance technologies are no longer suitable for this development trend. Existing automated repair equipment mostly focuses on single repair procedures (such as automatic cleaning or automatic coating) and has not formed a fully automated repair system covering the entire process of "surface pretreatment - repair construction - effect review".

Attached Figure Description

[0023] Figure 1 This diagram illustrates the main steps of the evaluation and repair method for composite sleeve skirts according to the present invention. Detailed Implementation

[0024] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of the invention with unnecessary detail.

[0025] like Figure 1 As shown, the present invention provides an evaluation and repair method for composite sleeve skirts, comprising: S1. The current aging status of the composite sleeve umbrella skirt is detected and evaluated to obtain the aging level; S2. Set repair decisions based on the assessed aging level; S3. Repair the composite sleeve umbrella skirt according to the repair decision.

[0026] In step S1, the aging grade includes hydrophobicity grade, pulverization grade, and cracking grade, specifically including: S11. Detect and evaluate the hydrophobicity level of the composite sleeve umbrella skirt surface; S12. Detect and evaluate the chalking level of the composite sleeve umbrella skirt surface; S13. Detect and evaluate the current cracking level of the composite sleeve skirt surface.

[0027] Specifically, step S11 includes: S111. Use an atomizing nozzle to spray water mist onto the surface of the composite sleeve skirt; S112. Obtain an image of water mist adhesion on the surface of the composite sleeve umbrella skirt after water spraying; S113. Perform image recognition processing on the surface water mist adhesion image and evaluate the water mist adhesion state, and output the hydrophobicity level according to the water mist adhesion state.

[0028] For example, the distance between the atomizing nozzle held by the robotic arm and the surface of the composite sleeve skirt is 20cm-30cm, the spray angle of the water jet from the atomizing nozzle is set to 50º-70º, and the spray volume of the atomizing nozzle is controlled to be 0.7mL / time-1mL / time, spraying water 1-3 times per second, spraying for 20s-30s. Preferably, the distance is 25cm, spraying water once per second, spraying for 25s.

[0029] The interval between water spraying from the atomizing nozzle is no more than 30 seconds. A camera is used to acquire images of water mist adhesion on the surface of the composite sleeve skirt. The amount and distribution of water mist on the surface are evaluated through image recognition processing, and different hydrophobicity levels are output. The hydrophobicity levels are divided into 7 levels from low to high: HC1, HC2, HC3, HC4, HC5, HC6, and HC7.

[0030] Specifically, step S12 includes: S121. Press the wiping cloth onto the surface of the composite sleeve umbrella skirt with a set pressure, and use the wiping cloth to rotate and wipe the surface of the composite sleeve umbrella skirt. S122. Obtain an image of the surface residue on the wiping cloth; S123. Perform image recognition processing on the surface residue image and evaluate the amount of residue adhering to the wiping cloth, and output the powdering level based on the amount of residue adhering.

[0031] In step S121, the pressure is set to 2N-4N, the contact surface area between the wiping cloth and the composite sleeve umbrella skirt is 1.5cm×1.5cm-2.5cm×2.5cm, and the wiping cloth is removed from the surface of the composite sleeve umbrella skirt after rotating 180º-360º.

[0032] For example, a robotic arm holds a wiping cloth and presses it onto the surface of the composite sleeve umbrella skirt. A pressure sensor is used to set the pressure to 3N. The contact surface area between the wiping cloth and the composite sleeve umbrella skirt is 2cm×2cm. The robotic arm rotates the wiping cloth 180º and then removes the wiping cloth from the surface of the composite sleeve umbrella skirt.

[0033] The system uses a camera to capture images of residue on the surface of a wiping cloth. Image recognition processing is then used to assess the amount of residue adhering to the cloth's surface, resulting in different chalking levels. The chalking levels are divided into five grades from low to high: F0, F1, F2, F3, and F4.

[0034] The specific meanings of the five powdering levels are as follows: F0 grade: No powdering; F1 grade: Very slight, only a trace amount of hard powder can be observed on the test cloth; F2 grade: Slight, a small amount of hard powder is present on the test cloth; Grade F3: Obviously, there is a lot of hard powder on the test cloth; F4 grade: Relatively heavy, with a large amount of hard powder adhering to the test cloth.

[0035] In step S13, the surface of the composite sleeve skirt is inspected and the cracking level is evaluated, including: S131. Obtain a magnified macro image of the surface of the composite sleeve umbrella skirt after wiping; S132. Perform image recognition and deep learning algorithm processing on the magnified macro image and evaluate the distribution and depth of cracks on the surface of the composite sleeve skirt, and output the cracking level based on the distribution and depth of the cracks.

[0036] For example, a macro-magnified image of the composite sleeve skirt surface after wiping is acquired using a macro camera. A deep learning algorithm is then used to process the macro-magnified image to evaluate the distribution and depth of cracks on the composite sleeve skirt surface, thereby outputting different cracking level results. The cracking level is divided into four levels from low to high: K0, K1, K2, and K3.

[0037] The specific meanings of the four cracking levels are as follows: K0 grade: No cracks; Grade K1: Minor cracking, few cracks; K2 grade: Moderate cracking, with a large number of cracks, and most cracks are less than 1 mm in depth; K3 grade: Severe cracking, dense cracks, and most cracks are deeper than 1 mm.

[0038] It should be noted that the composite sleeve skirt is tested and evaluated sequentially to determine its hydrophobicity level, pulverization level, and cracking level. The hydrophobicity level test can also be used to pre-clean the skirt surface, which facilitates the acquisition of a magnified macro image after cleaning in the cracking level test, thus improving the test accuracy and efficiency.

[0039] Step S2 specifically includes: The hydrophobicity grades are divided into HC1-HC7, the pulverization grades into F0-F4, and the cracking grades into K1-K3.

[0040] If the current hydrophobicity level is HC1-HC4, the current pulverization level is F0-F2, and the current cracking level is K0-K1, then the repair decision is to not repair the composite sleeve skirt, and the output result is recorded as J1. If the current hydrophobicity level is HC5-HC7, the current pulverization level is F0-F2, and the current cracking level is K0-K1, then the repair decision is to clean the composite sleeve skirt, and the output result is recorded as J2. If the current hydrophobicity level is HC1-HC4, the current pulverization level is F3-F4, and the current cracking level is K2-K3, then the repair decision is to remove the aging layer and apply a surface coating to the composite sleeve skirt, and the output result is recorded as J3. If the current hydrophobicity level is HC5-HC7, the current pulverization level is F3-F4, and the current cracking level is K2-K3, then the repair decision is to remove the aging layer and apply a surface coating to the composite sleeve skirt, and the output result is recorded as J4.

[0041] This step involves making different repair decisions based on the different aging states of the composite sleeve skirt, avoiding the traditional indiscriminate or one-size-fits-all repair methods.

[0042] It should be noted that those skilled in the art can also recombine different results of hydrophobicity level, pulverization level, and cracking level to formulate different remediation decisions to address different remediation scenarios in practical applications.

[0043] Step S3 specifically includes: When the output of the repair decision is J2, the cleaning process for the composite sleeve skirt is initiated. When the output of the repair decision is J3 or J4, the aging layer removal treatment and surface coating treatment are performed sequentially on the composite sleeve skirt.

[0044] If the output of the repair decision is J1, then no repair process will be performed; Specifically, the cleaning process for the composite sleeve umbrella skirt includes: spraying a cleaning agent onto the surface of the composite sleeve umbrella skirt to remove surface dirt and rinsing with clean water to restore the hydrophobicity level of the composite sleeve umbrella skirt surface.

[0045] It should be noted that, depending on the actual application, those skilled in the art can also use pressurized water rinsing, laser cleaning, or dry ice cleaning to clean the surface of the composite sleeve umbrella skirt in order to restore the hydrophobicity level of the surface of the composite sleeve umbrella skirt.

[0046] The treatment for removing the aged layer of the composite sleeve umbrella skirt includes: spraying a powder removal agent onto the surface of the composite sleeve umbrella skirt to remove surface dirt, powder layer and poorly adhered aged silicone rubber, thereby reducing the hydrophobicity and powdering level of the composite sleeve umbrella skirt surface.

[0047] It should be noted that, depending on the actual application, those skilled in the art can also use dry ice removal or laser pulse method to quickly remove surface dirt, powdery layer and poorly adhered aged silicone rubber from the composite sleeve skirt.

[0048] The surface coating treatment for the composite sleeve umbrella skirt includes: when the aging layer removal treatment is completed to the point that there is no chalking layer on the surface of the composite sleeve umbrella skirt, spraying / brushing vulcanized silicone rubber coating onto the surface of the composite sleeve umbrella skirt and allowing it to dry naturally for 24 hours.

[0049] In step S3, after the cleaning process of the composite sleeve umbrella skirt is completed or after the aging layer removal process and surface coating process of the composite sleeve umbrella skirt are completed in sequence, return to step S1 and repeat until the output result of the repair decision is J1, and end the entire repair process.

[0050] It should be noted that after performing the aging layer removal treatment on the composite sleeve umbrella skirt, you can return to step S12 to perform the chalking level detection and evaluation on the surface of the composite sleeve umbrella skirt until the chalking level result is F0, and then proceed to the surface coating treatment of the composite sleeve umbrella skirt.

[0051] It should be noted that, in order to avoid unnecessary interference with the description of the above embodiments of the present invention, although well-known implementation processes such as deep learning algorithms and image processing are omitted, this will not prevent those skilled in the art from implementing the above technical solutions based on the prior art.

[0052] The following are two specific examples of different repair decisions in this assessment and repair method.

[0053] Example 1 In this embodiment, the evaluation and repair method of this invention is applied to maintain the composite bushing skirt of a substation that has been in operation for 5 years. The specific process is as follows: The surface of the composite sleeve umbrella skirt was tested and evaluated, and the result of the hydrophobicity grade was HC6; The surface of the composite sleeve umbrella skirt was inspected and the chalking grade was evaluated as F2; The surface of the composite sleeve skirt was inspected and the cracking grade was evaluated as K1; When the hydrophobicity level HC6 is between HC5 and HC7, the pulverization level F2 is between F0 and F2, and the cracking level K1 is between K0 and K1, the output result of the repair decision is J2.

[0054] The repair decision output is J2, initiating the cleaning process for the composite sleeve skirt; After the cleaning process of the composite sleeve skirt is completed, return to the previous step and repeat the process until the output of the repair decision is J1, at which point the repair process ends.

[0055] Example 2 In this embodiment, the evaluation and repair method of this invention is applied to maintain the composite bushing skirt of a substation that has been in operation for 8 years. The specific process is as follows: The surface of the composite sleeve umbrella skirt was tested and the hydrophobicity grade was determined to be HC3. The surface of the composite sleeve umbrella skirt was inspected and the chalking grade was evaluated as F3; The surface of the composite sleeve skirt was inspected and the cracking grade was evaluated as K2.

[0056] When the hydrophobicity level HC3 is between HC1 and HC4, the pulverization level F3 is between F3 and F4, and the cracking level K2 is between K2 and K3, the output result of the repair decision is J3.

[0057] The repair decision output is J3, which sequentially initiates the removal of the aging layer and surface coating treatment on the composite sleeve skirt.

[0058] In this process, after the aging layer removal treatment is performed on the composite sleeve skirt in sequence, the process is repeated until the powdering grade result is F0, and then the surface coating treatment is started.

[0059] After the surface coating treatment of the composite sleeve skirt is completed, return to re-execute until the output result of the repair decision is J1, and then end the repair process.

[0060] Example 3 Based on the same inventive concept, this invention provides an evaluation and repair system for composite sleeve skirts, comprising: The detection and evaluation module is used to detect and evaluate the current aging status of the composite sleeve skirt to obtain the aging level; The decision-making module is used to set repair decisions based on the assessed aging level; The repair module is used to repair the composite sleeve skirt based on the repair decision results.

A first image processor is used to perform image recognition processing on the surface water mist adhesion image and evaluate the water mist adhesion state, and output the hydrophobicity level according to the water mist adhesion state.

[0063] For example, in this embodiment, the atomizing nozzle and the first camera of the water mist sprayer are configured at the end of the first robotic arm so that the first robotic arm can be used to adjust the atomizing nozzle to spray water mist onto the surface of the composite sleeve umbrella skirt and to acquire images through the first camera. The images are processed by the first image processor to automatically detect the surface of the composite sleeve umbrella skirt and evaluate the hydrophobicity level.

[0064] The powdering detection and evaluation unit includes: A rotating wiping head is used to press a wiping cloth onto the surface of the composite sleeve umbrella skirt with a set pressure, and to use the wiping cloth to rotate and wipe the surface of the composite sleeve umbrella skirt. The second camera is used to acquire images of surface residue on the wiping cloth; The second image processor is used to perform image recognition processing on the surface residue image and evaluate the amount of residue adhering to the wiping cloth, and output the powdering level according to the amount of residue adhering.

[0065] For example, in this embodiment, the rotating wiping head and the second camera are configured at the end of the second robotic arm so that the second robotic arm can adjust the rotating wiping head to set the pressure and press it onto the surface of the composite sleeve umbrella skirt for rotating wiping, and the second camera can acquire images. The images are processed by the second image processor to automatically detect the surface of the composite sleeve umbrella skirt and evaluate the powdering level.

[0066] The crack detection and evaluation unit includes: The third camera is used to acquire a magnified macro image of the surface of the composite sleeve skirt after wiping. The third image processor is used to perform image recognition processing and deep learning algorithm processing on the magnified macro image and evaluate the distribution and depth of cracks on the surface of the composite sleeve skirt, and output the cracking level according to the distribution and depth of the cracks.

[0067] For example, in this embodiment, the third camera is configured at the end of the third robotic arm so that the third robotic arm can be used to adjust the third camera to the surface of the composite sleeve umbrella skirt to obtain a magnified image. The image is processed by the third image processor to automatically detect the surface of the composite sleeve umbrella skirt and evaluate the crack level.

[0068] The decision module receives the hydrophobicity level, pulverization level, and crack level as inputs, and outputs the decision result as output.

[0069] Specifically, the hydrophobicity grade is divided into HC1-HC7, the pulverization grade is divided into F0-F4, and the cracking grade is divided into K1-K3.

[0070] The decision-making module processes the following steps: When the decision module obtains that the current hydrophobicity level output by the hydrophobicity detection and evaluation unit is HC1-HC4, the current pulverization level output by the pulverization detection and evaluation unit is F0-F2, and the current cracking level output by the crack detection and evaluation unit is K0-K1, the repair decision of the decision module is not to repair the composite sleeve skirt, and the output result is recorded as J1. When the decision module obtains that the current hydrophobicity level output by the hydrophobicity detection and evaluation unit is HC5-HC7, the current pulverization level output by the pulverization detection and evaluation unit is F0-F2, and the current cracking level output by the crack detection and evaluation unit is K0-K1, the repair decision of the decision module is to clean the composite sleeve skirt, and the output result is recorded as J2.

When the decision module obtains that the current hydrophobicity level output by the hydrophobicity detection and evaluation unit is HC5-HC7, the current pulverization level output by the pulverization detection and evaluation unit is F3-F4, and the current cracking level output by the crack detection and evaluation unit is K2-K3, the repair decision of the decision module is to perform aging layer removal treatment and surface coating treatment on the composite sleeve skirt, and the output result is recorded as J4.

[0071] The repair module includes: The cleaning unit is used to clean the surface of the composite sleeve umbrella skirt by means of cleaning agent cleaning, pressurized water rinsing, laser cleaning or dry ice cleaning when the output result of the decision module is J2, so as to restore the hydrophobicity of the surface of the composite sleeve umbrella skirt.
