Description

Technical Field

[0001] The invention relates to the technical field of tension clamp testing, and in particular to a tension clamp performance testing method and system. Background Art

[0002] As a key connection component of the transmission line, the performance of the tension clamp is directly related to the safety and stability of the entire transmission system. The clamp is prone to fatigue, deformation, and even breakage under long-term tension and harsh environmental conditions (such as corrosion, wind vibration, etc.). This damage will cause the conductor to loosen or break, thus endangering the normal operation of the power system. With the continuous expansion of the global power grid and the increase in electricity demand, it has become more important to ensure the stability and durability of each component of the power grid. The reliability test and evaluation of the tension clamp has become the focus of the maintenance of the transmission system.

[0003] Strain clamps are usually exposed to harsh outdoor environments such as wind, rain, salt spray, and temperature changes. They will be affected by multiple factors such as corrosion, current thermal effects, tension, and vibration during long-term use, which may lead to a decrease in mechanical and electrical performance. Therefore, it is necessary to conduct multi-dimensional performance tests on the tension clamps to ensure their reliability under various extreme conditions. Environmental corrosion and frequent vibrations will aggravate the wear and fatigue of the tension clamps and increase the risk of failure.

[0004] There are still some deficiencies in the existing technology for the research on the performance test of tension clamps: first, traditional tension clamp testing technology often only focuses on one aspect of performance, but the tension clamps in actual working conditions are subjected to multiple forces; second, traditional manual testing methods are difficult to meet the rapid detection needs of power systems, and the test coupling capability and the integration capability of multiple data are insufficient, the factors considered are not comprehensive enough, and the multi-factor coupling effect is ignored, and the overall performance of the clamps in complex environments cannot be effectively predicted; third, traditional tension clamp tests are often scattered and isolated, and various aspects of performance data cannot be effectively integrated. There is a lack of correlation analysis of multiple data, and the isolated data leads to incomplete information, making it difficult to discover potential hidden dangers and problem patterns, ignoring the complex relationship under the joint influence of multiple factors, affecting the understanding and optimization of the entire life cycle of the tension clamp, resulting in inaccurate diagnosis and prediction of performance tests, and easily ignoring the combined impact of the synergistic effect of multiple factors on the tension clamp, resulting in misjudgment.

[0005] Therefore, how to provide a solution that provides quantitative indicators for the performance of the tension clamp, can determine the performance test assessment level of the tension clamp, and ensure the consistency and reliability of the assessment process, reduce misjudgment and improve the accuracy of the assessment has become a problem that needs to be solved urgently. Summary of the invention

[0006] The embodiments of the present invention provide a method and system for testing the performance of a tension clamp to solve the problems in the prior art of insufficient coupling capability and multiple data integration capability of traditional tension clamp testing, insufficient consideration of factors, and neglect of the coupling effect of multiple factors.

[0090] The technical solution provided by the embodiment of the present invention may have the following beneficial effects:

[0091] (1) The present invention provides a performance testing method and testing system for a tension clamp, which uses multi-dimensional characteristics such as corrosion, vibration, mechanical properties and electrical properties as evaluation factors, respectively, and can comprehensively evaluate the overall performance of the tension clamp from different angles. The evaluation factors and deviation values ​​calculated based on the corrosion characteristics, vibration characteristics, mechanical and electrical performance data provide quantitative indicators for the performance of the tension clamp. The performance constraint model of the tension clamp can integrate various evaluation factors and deviation values, and finally determine the performance test evaluation level of the tension clamp, which can ensure the consistency and reliability of the evaluation process and reduce human errors.

[0092] (2) The present invention determines the performance test and evaluation level of the tension clamp by combining the corrosion and vibration coupling test scheme and the tension and current coupling test scheme. The multi-dimensional test can better simulate the coupling effect in actual working conditions, ensuring that the evaluation result is closer to the performance of the clamp in the real environment. The interaction between corrosion, vibration, tension and current may have a synergistic effect on the tension clamp, and single factor testing often cannot capture these effects. Through multiple coupling tests, the performance of the clamp can be more accurately evaluated and its reliability in long-term use can be determined, thereby reducing misjudgment and improving the accuracy of the evaluation. Intelligent and automated detection can simplify the process and reduce human intervention, thereby accelerating the evaluation process and providing real-time monitoring and rapid response.

[0108] Figure 1-Figure 2 An embodiment of a method for testing performance of a tension clamp of the present invention is shown.

[0109] In this optional embodiment, the tension clamp performance testing method includes:

[0110] Step S101: Based on the corrosion and vibration coupling test scheme, the corrosion characteristic data and vibration characteristic data of the strain clamp are obtained by using the strain clamp test equipment, and according to the tension and current coupling test scheme, the mechanical property data and electrical property data of the strain clamp are obtained by using the strain clamp test equipment;

[0111] Step S103, according to the corrosion characteristic data, vibration characteristic data, mechanical property data and electrical property data of the tension clamp, through the characteristic analysis method, determine the mechanical property evaluation deviation value of the tension clamp, and establish the evaluation factor set of the tension clamp;

[0112] Step S105: Based on the performance constraint model of the tension clamp, input the assessment factor set of the tension clamp, output the performance assessment factor of the tension clamp, and use the performance assessment range of the tension clamp to divide the performance test assessment level of the tension clamp.

[0113] Specifically, under the corrosion and vibration coupling test scheme stored in the database, based on the strain clamp test equipment, the corrosion characteristic data of the strain clamp and the vibration characteristic data of the strain clamp are obtained; the corrosion and vibration coupling test scheme stored in the database is a combination of different humid and hot environments, salt spray environments and multi-frequency vibration conditions, and the strain clamp test equipment integrates multiple testing functions, including an intelligent strain clamp prototype tensile test device, a current loading system, a vibration test device, a corrosion environment simulation system, etc., which can apply multiple forces such as tension, current, vibration and corrosion, and collect data, and obtain the corrosion characteristic assessment factor of the strain clamp based on the corrosion characteristic data of the strain clamp; obtain the vibration characteristic assessment factor of the strain clamp based on the vibration characteristic data of the strain clamp, and determine the deviation value of the mechanical property assessment of the strain clamp.

[0114] In this optional embodiment, the corrosion characteristic data of the tension clamp includes the thickness of the corrosion layer on the surface of the tension clamp, the maximum depth of the corrosion pit of the tension clamp, and the change rate of the surface resistance of the tension clamp;

[0115] Specifically, the thickness of the surface corrosion layer refers to the thickness of the oxide or corrosion product formed on the metal surface of the wire clamp, which reflects the exposure time and the accumulation of corrosion degree of the wire clamp in the corrosive environment, and is obtained based on X-ray photoelectron spectroscopy. The maximum depth of the corrosion pit refers to the deepest depression or "pit" formed on the surface of the wire clamp due to local corrosion. The corrosion pit will cause stress concentration when subjected to force, which may reduce the overall strength of the wire clamp. The depth of the corrosion pit can show the severity of local corrosion. The surface contour map of the corrosion pit is generated by 3D imaging technology, and the depth of the corrosion pit is measured non-contact. The surface resistance change rate refers to the degree of change in the surface resistance of the wire clamp during the corrosion process. The accumulation of corrosion products or the formation of an oxide layer will increase the resistance and affect the conductive properties of the wire clamp. The increase in the surface resistance change rate means that the conductivity of the wire clamp decreases, affecting the efficiency of power transmission. It is obtained based on a four-probe resistance tester.

[0116] Specifically, the formation of corrosion layer and corrosion pits are different manifestations of corrosion. As the thickness of the corrosion layer increases, the depth of the corrosion pit may also increase, because the local area of ​​the metal is more susceptible to corrosion by corrosive substances and deepens. The corrosion layer and corrosion pits can jointly reflect the overall situation of corrosion, and the combined effect of the two will accelerate the deterioration of the overall strength of the wire clamp. The thickening of the corrosion layer usually reduces the conductivity of the metal, resulting in an increase in surface resistance. The increase in the thickness of the corrosion layer is often proportional to the change in surface resistance. As the corrosion layer accumulates, the resistance gradually increases, affecting the passage of current and reducing the electrical performance of the wire clamp. The formation of corrosion pits will also have an impact on the surface resistance, especially when the current path is destroyed or the conductive cross-sectional area is reduced. Deep corrosion pits are prone to stress concentration, causing microcracks or surface unevenness, which may further increase resistance.

[0117] The vibration characteristic data of the tension clamp include the natural frequency deviation rate of the tension clamp, the amplitude of the tension clamp and the resonance frequency bandwidth of the tension clamp;

[0118] Specifically, the vibration characteristic data of the strain clamp include the natural frequency deviation rate of the strain clamp, the amplitude of the strain clamp, and the resonant frequency bandwidth of the strain clamp; based on the vibration characteristic data of the strain clamp, the vibration characteristic assessment factor of the strain clamp is obtained, and the vibration characteristic assessment factor of the strain clamp is used as the analysis basis for determining the performance test assessment level of the strain clamp.

[0119] Specifically, the natural frequency deviation rate indicates the difference between the natural frequency of the wire clamp under actual working conditions and the design frequency, which can reflect the stability of the frequency offset of the wire clamp during vibration. The amplitude is the displacement amplitude of the wire clamp under vibration, which indicates the intensity of its vibration response. A larger amplitude may increase the risk of fatigue damage. The resonant frequency bandwidth is the frequency range near the resonant frequency of the wire clamp. The narrower the bandwidth, the less sensitive the structure is to the vibration frequency, which helps to improve vibration resistance. The exciter and accelerometer are used together to measure the natural frequency deviation rate and amplitude data, while the spectrum analyzer or modal analysis system can obtain and analyze the resonant frequency bandwidth.

[0120] Specifically, the natural frequency deviation rate indicates the deviation between the natural frequency and the design frequency of the wire clamp in actual use. The smaller the deviation, the more stable the dynamic characteristics of the wire clamp, reducing the risk of accidental resonance. The amplitude is the displacement amplitude of the wire clamp under vibration load. The larger the amplitude, the stronger the vibration response, which increases the possibility of fatigue damage. The resonant frequency bandwidth indicates the sensitive frequency range around the resonant frequency. The narrower the bandwidth, the more concentrated the response of the structure to vibrations of a specific frequency, and the better the vibration resistance. A smaller natural frequency deviation rate and a narrower resonant frequency bandwidth help control the amplitude within a safe range, thereby improving the vibration resistance reliability of the wire clamp and extending its service life. The deviation rate is the ratio of the absolute value of the actual value minus the reference value to the reference value.

[0121] The mechanical performance data of the tension clamp include the elongation of the tension clamp and the tensile strength limit of the tension clamp;

[0122] Specifically, under the tension and current coupling test scheme stored in the database, based on the tension clamp test equipment, the mechanical performance data of the tension clamp and the electrical performance data of the tension clamp are obtained; the tension and current coupling test scheme stored in the database is a combination of applying different tension conditions and current conditions, based on the mechanical performance data of the tension clamp, and combined with the mechanical performance assessment deviation value of the tension clamp, the mechanical performance assessment factor of the tension clamp is obtained; based on the electrical performance data of the tension clamp, the electrical performance assessment factor of the tension clamp is obtained.

[0123] Specifically, the elongation indicates the plastic deformation ability of the wire clamp under tensile stress, usually expressed as the percentage of the maximum elongation before the material breaks to the original length. The higher the elongation, the better the plasticity of the wire clamp, the more ductile and tough the material is when stretched, and it can adapt to a certain degree of deformation under tension without breaking easily. The tensile strength limit refers to the maximum stress value that the wire clamp material can withstand in a tensile test, that is, the highest tensile force before breaking, usually in megapascals (MPa). The higher the tensile strength limit, the greater the strength of the material under stress and the less likely it is to break. The elongation and tensile strength limit of the tension clamp are measured by a tensile testing machine.

[0124] The electrical performance data of the tension clamp includes the conductivity of the tension clamp, the power loss of the tension clamp and the temperature rise of the tension clamp;

[0125] The assessment factor set of the tension clamp includes the corrosion characteristic assessment factor, vibration characteristic assessment factor, mechanical property assessment factor and electrical property assessment factor of the tension clamp.

[0126] Specifically, the electrical performance data of the strain clamp include the electrical conductivity of the strain clamp, the power loss of the strain clamp, and the temperature rise of the strain clamp; based on the electrical performance data of the strain clamp, the electrical performance assessment factor of the strain clamp is obtained, and the electrical performance assessment factor of the strain clamp is used as the analysis basis for determining the performance test assessment level of the strain clamp.

[0127] Specifically, conductivity refers to the ability of a material to conduct electric current, usually expressed in Siemens per meter (S / m). The higher the conductivity, the more efficient the wire clamp is in conducting current, the lower the resistance, and the less energy loss when current passes through. Conductivity is an important parameter that affects the efficiency of power transmission. The conductivity is obtained by a four-probe resistance tester or a conductivity meter, which reflects the conductivity of the wire clamp. Power loss refers to the energy loss caused by resistance when current passes through the wire clamp, which is usually manifested as heat dissipation. The power loss can reflect the energy efficiency level of the wire clamp. The higher the power loss, the more energy is lost in the form of heat, which may cause the temperature to rise. Use a power meter or a DC resistance tester to measure the power loss when current passes through the wire clamp.

[0128] Specifically, temperature rise refers to the increase in temperature generated when current passes through the wire clamp. It usually refers to the difference between the working temperature of the wire clamp when current flows and the ambient temperature. The temperature rise reflects the heat dissipation capacity and conductivity of the wire clamp. A higher temperature rise may cause material aging and strength loss. The temperature of the wire clamp is monitored in real time through a thermocouple temperature sensor or an infrared thermometer, and the difference between the working temperature and the ambient temperature, i.e., the temperature rise, is calculated.

[0129] Specifically, under the same current conditions, lower resistance will lead to lower power loss. Power loss is the source of heat generated by the wire clamp during the conduction process. Heat will cause the temperature of the wire clamp to rise, that is, temperature rise. The greater the power loss, the more heat is generated, and the higher the temperature rise. Higher conductivity will reduce power loss, thereby reducing temperature rise. The higher the conductivity, the lower the resistance, and the lower the temperature rise, which is crucial to the durability and performance stability of the wire clamp, especially under long-term high current conditions.

[0130] In this optional embodiment, according to the corrosion characteristic data, vibration characteristic data, mechanical property data and electrical property data of the tension clamp, the mechanical property evaluation deviation value of the tension clamp is determined by a characteristic analysis method, and an evaluation factor set of the tension clamp is established, including:

[0131] Step S1031, solving the corrosion characteristic assessment factor of the tension clamp based on the corrosion characteristic data of the tension clamp;

[0132] Step S1033, calculating the vibration characteristic evaluation factor of the strain clamp according to the vibration characteristic data of the strain clamp, and determining the mechanical performance evaluation deviation value of the strain clamp;

[0133] Step S1035, based on the mechanical property data of the tension clamp and in combination with the mechanical property evaluation deviation value of the tension clamp, solving the mechanical property evaluation factor of the tension clamp;

[0134] Step S1037, calculate the electrical characteristic assessment factor of the strain clamp according to the electrical characteristic data of the strain clamp, and combine the corrosion characteristic assessment factor, vibration characteristic assessment factor and mechanical characteristic assessment factor of the strain clamp to form an assessment factor set for establishing the strain clamp.

[0135] In this optional embodiment, the corrosion characteristic evaluation factor of the tension clamp is expressed as:

[0136]

[0137] Wherein, α is the corrosion characteristic assessment factor of the tension clamp, hd is the thickness of the corrosion layer on the surface of the tension clamp, sd is the maximum depth of the corrosion pit of the tension clamp, bh is the rate of change of the surface resistance of the tension clamp, μ1 is the compensation factor of the set hd, μ2 is the compensation factor of the set sd, and μ3 is the compensation factor of the set bh;

[0138] Specifically, the analysis process is as follows: the corrosion characteristic data of the tension clamp specifically include the thickness of the surface corrosion layer of the tension clamp, the maximum depth of the corrosion pit of the tension clamp, and the surface resistance change rate of the tension clamp; based on the corrosion characteristic data of the tension clamp, the corrosion characteristic assessment factor of the tension clamp is obtained, and the corrosion characteristic assessment factor of the tension clamp is used as the analysis basis for determining the performance test assessment level of the tension clamp.

[0139] Specifically, analyzing the thickness of the corrosion layer, the depth of the corrosion pits, and the rate of change of the surface resistance can provide a comprehensive understanding of the corrosion state of the tension clamp, reflecting the rate and degree of degradation of the clamp in a corrosive environment, and is an important indicator of its long-term corrosion resistance. The present invention incorporates the corrosion characteristic assessment factor into the performance grade assessment, which can ensure that the selected clamp can maintain good corrosion resistance in a specific environment, thereby extending the service life of the equipment. Accurately assessing the corrosion situation can effectively identify potential corrosion hazards and prevent failure or breakage due to corrosion. In a corrosive environment, tension clamps are at greater risk of damage due to corrosion, and the corrosion characteristic assessment factor can help identify clamps with high corrosion risks in advance.

[0140] Specifically, the above-mentioned tension clamp corrosion characteristic assessment factor is calculated by the thickness of the surface corrosion layer of the tension clamp, the maximum depth of the corrosion pit of the tension clamp, and the surface resistance change rate of the tension clamp. HD, SD, and BH are normalized, and the corrosion condition of the tension clamp can be comprehensively analyzed by combining the corrosion layer thickness, corrosion pit depth, and surface resistance change rate. The corrosion layer thickness reflects the cumulative degree of uniform corrosion, the corrosion pit depth shows the severity of local corrosion, and the resistance change rate directly shows the impact of corrosion on the conductive properties, which can more comprehensively and accurately reflect the actual corrosion impact. During the corrosion process, oxides, hydroxides, or other corrosion product layers gradually form on the metal surface. These corrosion products usually have high resistance. As the corrosion layer thickens, the surface resistance will gradually increase. The corrosion characteristic assessment factor quantifies the corrosion state by integrating multiple corrosion indicators into a single value, which is convenient for direct comparison of tension clamps in different batches or different environments, and provides a scientific basis for screening or replacement.

[0141] Specifically, the compensation factors of HD, SD, and BH set above are obtained from a database, and a mapping set of the historically measured thickness of the surface corrosion layer of the tension clamp, the maximum depth of the corrosion pit of the tension clamp, the rate of change of the surface resistance of the tension clamp and the compensation factors of HD, SD, and BH is established based on historical data to obtain the compensation factors of HD, SD, and BH corresponding to the current HD, SD, and BH.

[0142] Specifically, σ1, σ2, σ3, τ1, τ2, ε1, ε2, and ε3 in the subsequent solutions of the present invention are also obtained through a mapping set of historical data and compensation factors established in a database, that is, the corresponding compensation factors are obtained according to the current data.

[0143] In this optional embodiment, the vibration characteristic evaluation factor of the tension clamp is expressed as:

[0144]

[0145] In the formula, β is the vibration characteristic evaluation factor of the tension clamp, gp is the natural frequency deviation rate of the tension clamp, zf is the amplitude of the tension clamp, dk is the resonance frequency bandwidth of the tension clamp, σ1 is the compensation factor of the set gp, σ2 is the compensation factor of the set zf, σ3 is the compensation factor of the set dk, and e is a natural constant.

[0146] Specifically, the vibration characteristic assessment factor obtained based on the vibration characteristic data of the tension clamp (including the inherent frequency deviation rate, amplitude, and resonant frequency bandwidth of the tension clamp) is used as the analysis basis for the performance test assessment level of the tension clamp, reflecting the dynamic response capability and vibration resistance of the clamp under actual working conditions. The inherent frequency deviation rate shows the stability of the clamp to the design frequency, the amplitude reflects its displacement response under vibration, and the resonant frequency bandwidth reveals the resonance sensitivity range of the clamp. The vibration characteristic assessment factor formed by these data can help comprehensively and quantitatively evaluate the vibration resistance and fatigue durability of the clamp in a complex environment, and be included in the performance level analysis, making the selection and application of the tension clamp more accurate and safe, helping to reduce damage and failure caused by vibration, and improving the stability of the power system. This factor provides a scientific basis for life prediction and fault warning.

[0147] It should be explained that the above-mentioned vibration characteristic assessment factor of the tension clamp is calculated by the natural frequency deviation rate of the tension clamp, the amplitude of the tension clamp, and the resonant frequency bandwidth of the tension clamp. After normalizing gp, zf, and dk, the natural frequency deviation rate, amplitude, and resonant frequency bandwidth respectively reflect the dynamic characteristics and vibration resistance of the clamp under different vibration conditions. Integrating these three data into a comprehensive vibration characteristic assessment factor can fully understand whether the clamp has good vibration resistance in actual working conditions.

[0148] Specifically, the amplitude and resonant frequency bandwidth provide information on stress and amplitude concentration in vibration, while the natural frequency deviation rate indicates whether there is a risk of resonance caused by frequency offset. Comprehensive analysis can help identify the potential fatigue damage risk of the wire clamp in a vibration environment and provide a scientific basis for early maintenance and replacement. A single parameter may not be able to accurately evaluate the vibration characteristics of the wire clamp, but through the comprehensive factors of the natural frequency deviation rate, amplitude and resonant frequency bandwidth, it is possible to quantify the complex dynamic behavior in vibration, which can more accurately evaluate the overall stability of the structure and ensure the safety of the wire clamp in complex environments.

[0149] Specifically, the vibration characteristic assessment factor of the tension clamp is stored as a designated label, and the designated label is compared with each set label stored in the database one by one to determine the set label that is the same as the designated label, and obtain the tension clamp mechanical property assessment deviation value corresponding to the set label in the database.

[0150] Specifically, the vibration characteristic assessment factor of the tension clamp is stored as a specified label, and is compared one by one with each set label stored in the database to determine the set label that is the same as the specified label, and then obtain the mechanical property assessment deviation value of the tension clamp corresponding to the set label. This process has many benefits. Through this comparison method, historical data that matches the current test conditions in terms of vibration characteristics can be automatically and quickly matched. Providing a reference basis for the mechanical property deviation of the current clamp not only improves the accuracy of the assessment, but also reduces the need for repeated testing, thereby optimizing resource utilization.

[0151] Specifically, this comparison method effectively utilizes the historical data accumulated in the database, which helps to discover the potential weaknesses of the wire clamp under complex working conditions during the assessment, and can more accurately predict the status of the equipment, extend the service life and reduce the risk of unexpected failures. The vibration characteristic assessment factor reflects the dynamic response of the wire clamp under vibration conditions, including the natural frequency deviation, amplitude and resonant frequency bandwidth. High vibration response may cause mechanical stress concentration and fatigue damage, which will change the actual mechanical properties of the wire clamp and increase the deviation of the mechanical properties. When the vibration characteristic assessment factor shows a higher vibration sensitivity, the deviation value of the mechanical property assessment tends to increase, indicating that the mechanical stability of the wire clamp in a vibration environment is reduced.

[0152] In this optional embodiment, determining the deviation value of the mechanical performance assessment of the tension clamp includes:

[0153] Based on the vibration characteristic assessment factor of the tension clamp, a specified label is generated through data storage operation;

[0154] Compare the specified tags with the set tags stored in the database one by one;

[0155] Based on the results of one-to-one comparison, the set label that is the same as the specified label is determined, and the deviation value of the mechanical performance assessment of the tension clamp corresponding to the set label is obtained.

[0156] In this optional embodiment, the mechanical property evaluation factor of the tension clamp is expressed as:

[0157]

[0158] In the formula, γ is the mechanical property evaluation factor of the tension clamp, θ is the mechanical property evaluation deviation value of the tension clamp, ys is the elongation of the tension clamp, jx is the tensile strength limit of the tension clamp, τ1 is the compensation factor of the set ys, and τ2 is the compensation factor of the set jx;

[0159] Specifically, the specific analysis process is: the mechanical performance data of the strain wire clamp specifically includes the elongation of the strain wire clamp and the tensile strength limit of the strain wire clamp; based on the mechanical performance data of the strain wire clamp and combined with the deviation value of the mechanical performance assessment of the strain wire clamp, the mechanical performance assessment factor of the strain wire clamp is obtained, and the mechanical performance assessment factor of the strain wire clamp is used as the analysis basis for determining the performance test assessment grade of the strain wire clamp.

[0160] Specifically, based on the mechanical property data of the tension clamp (including elongation and tensile strength limit), combined with the mechanical property evaluation deviation value, the mechanical property evaluation factor is used as an analytical basis for determining the performance test evaluation level of the tension clamp, which has important benefits. The elongation data reflects the ductility of the clamp, the tensile strength limit reflects its strength performance under the ultimate tension, and the deviation value further corrects the accuracy of these data under different conditions. The mechanical property evaluation factor can provide quantitative support for the strength and durability of the tension clamp under actual working conditions, making the evaluation level more accurate and ensuring the service life and safety of the clamp. The power system can reasonably select and configure the clamp, prevent premature failure, reduce maintenance costs, and improve the overall stability and safety of the system, ensuring that the tension clamp can operate reliably under high load and complex environments.

[0161] It should be explained that the above-mentioned mechanical property assessment factor of the tension wire clamp is calculated through the elongation of the tension wire clamp, the tensile strength limit of the tension wire clamp and the deviation value of the mechanical property assessment of the tension wire clamp. After normalizing ys and jx, the elongation reflects the ductility and toughness of the material, and the tensile strength limit shows its bearing capacity and fracture resistance. The mechanical property deviation value helps to quantify the performance deviation, and the mechanical property assessment factor can comprehensively evaluate the mechanical performance of the wire clamp to ensure its reliability in tension and stress environments. The mechanical property deviation value can correct the actual performance of the material and make up for the shortcomings of simple experimental data. By introducing the deviation value, the assessment factor can more accurately reflect the mechanical properties of the wire clamp under real application conditions, providing higher credibility for the evaluation results.

[0162] In this optional embodiment, the electrical characteristic evaluation factor of the tension clamp is expressed as:

[0163]

[0164] In the formula, δ is the electrical performance assessment factor of the tension clamp, dd is the conductivity of the tension clamp, sh is the power loss of the tension clamp, ws is the temperature rise of the tension clamp, ε1 is the compensation factor of the set dd, ε2 is the compensation factor of the set sh, and ε3 is the compensation factor of the set ws.

[0165] Specifically, based on the electrical performance data of the tension clamp (including conductivity, power loss, and temperature rise), the electrical performance evaluation factor is used as the analytical basis for determining the performance test evaluation level of the tension clamp. The conductivity data reflects the current conduction capacity of the clamp, the power loss shows its energy loss, and the temperature rise reflects its heat dissipation efficiency. The electrical performance evaluation factor generated by integrating these key indicators can comprehensively evaluate the electrical reliability of the clamp and ensure its safety performance under high load current conditions. Using this factor as the basis for evaluation level will help the power system select clamps with excellent conductivity, low power consumption and good heat dissipation, avoid the decrease in power transmission efficiency and equipment aging due to excessive temperature rise, thereby improving the safety and operation efficiency of the overall power grid, reducing maintenance costs, and ensuring the long-term and stable operation of equipment.

[0166] It should be explained that the electrical performance evaluation factor of the above-mentioned tension clamp is calculated through the conductivity of the tension clamp, the power loss of the tension clamp, and the temperature rise of the tension clamp. dd, sh, and ws are normalized. The conductivity reflects the efficiency of the clamp material in conducting current, the power loss shows the energy loss, and the temperature rise reflects the heat dissipation performance. The electrical performance evaluation factor obtained by combining these parameters can comprehensively measure the conductivity and energy efficiency level of the clamp under high current conditions.

[0167] Specifically, higher power loss and temperature rise may cause material overheating and increase the risk of thermal damage. Electrical performance assessment factors can help identify potential degradation and material aging risks caused by high temperature, provide support for preventive maintenance, and extend the service life of wire clamps. Electrical performance assessment factors can help screen out wire clamps with good conductivity and low loss to reduce power loss and improve power transmission efficiency. More efficient electrical performance means less energy loss in the power system and lower overall operating costs. The higher the rating of the tension clamp performance test, the better.

[0168] Specifically, the assessment factor set of the tension clamp consisting of the tension clamp corrosion characteristic assessment factor, the tension clamp vibration characteristic assessment factor, the tension clamp mechanical property assessment factor and the tension clamp electrical property assessment factor is introduced into the tension clamp performance constraint model to determine the tension clamp performance test assessment level.

[0169] In this optional embodiment, based on the performance constraint model of the tension clamp, the evaluation factor set of the tension clamp is input, the performance evaluation factor of the tension clamp is output, and the performance evaluation range of the tension clamp is defined by using the performance evaluation of the tension clamp, and the performance test evaluation level of the tension clamp is divided into:

[0170] Step S1051, importing the assessment factor set of the tension clamp into the tension clamp performance constraint model to obtain the tension clamp performance assessment factor;

[0171] The expression of the tension clamp performance constraint model is:

[0172]

[0173] In the formula, ω is the performance assessment factor of the tension clamp; α is the corrosion characteristic assessment factor of the tension clamp; β is the vibration characteristic assessment factor of the tension clamp; γ is the mechanical performance assessment factor of the tension clamp; δ is the electrical performance assessment factor of the tension clamp;

[0174] Specifically, the specific analysis process of the performance constraint model of the tension clamp is shown in the expression. The corrosion characteristic assessment factor, vibration characteristic assessment factor, mechanical performance assessment factor and electrical performance assessment factor of the tension clamp are introduced into the performance constraint model of the tension clamp. The performance assessment factor of the tension clamp is obtained through comprehensive analysis, and it is used as the basis for determining the performance test assessment level and compared with the performance assessment definition range stored in the database. When the performance assessment factor falls within the definition range, the performance level of the tension clamp is determined to be level 2, indicating that the equipment is operating normally within the standard range. If the assessment factor is less than the minimum value of the definition range, the equipment has potential functional damage or degradation, and further diagnosis is required, and a first-level diagnostic assessment level is assigned. When the assessment factor is greater than the maximum value, it indicates that the equipment exceeds the normal performance limit, the performance is excellent, and it is assessed as level 3. It can not only accurately identify the operating status of the tension clamp, but also provide a scientific basis for preventive maintenance and fault handling, extend the life of the equipment, ensure the safe and stable operation of the power grid, and effectively optimize the allocation of maintenance resources. It should be noted that the performance assessment definition range of the tension clamp is a left-closed and right-closed interval.

[0175] Step S1053, comparing the performance assessment factor of the tension clamp with the performance assessment definition range of the tension clamp, if the performance assessment factor of the tension clamp falls within the performance assessment definition range of the tension clamp, the performance test assessment level of the tension clamp is classified as level 2;

[0176] Step S1055: if the performance assessment factor of the tension clamp does not fall within the defined range of the performance assessment of the tension clamp, and the performance assessment factor of the tension clamp is less than the minimum value in the defined range of the performance assessment of the tension clamp, the performance test assessment level of the tension clamp is classified as level one;

[0177] Step S1057: if the performance assessment factor of the tension clamp does not fall within the defined range of the performance assessment of the tension clamp, and the performance assessment factor of the tension clamp is greater than the maximum value in the defined range of the performance assessment of the tension clamp, the performance test assessment level of the tension clamp is divided into three levels.

[0178] Specifically, Figure 3As shown in the figure, the specific analysis process is as follows: the strain clamp corrosion characteristic assessment factor, the strain clamp vibration characteristic assessment factor, the strain clamp mechanical property assessment factor and the strain clamp electrical property assessment factor are introduced into the strain clamp performance constraint model, and the strain clamp performance assessment factor is obtained by comprehensive analysis. The strain clamp performance assessment factor is used as the analysis basis for determining the strain clamp performance test assessment level; the strain clamp performance assessment factor is compared with the strain clamp performance assessment definition range stored in the database; if the strain clamp performance assessment factor falls within the strain clamp performance assessment definition range, the strain clamp performance assessment factor corresponds to The performance test assessment level of the tension wire clamp is level two; if the performance assessment factor of the tension wire clamp does not fall within the defined range of the tension wire clamp performance assessment, and the performance assessment factor of the tension wire clamp is less than the minimum value in the defined range of the tension wire clamp performance assessment, then the simulation failure diagnosis assessment level of the hardware to be diagnosed corresponding to the performance assessment factor of the tension wire clamp is level one; if the performance assessment factor of the tension wire clamp does not fall within the defined range of the tension wire clamp performance assessment, and the performance assessment factor of the tension wire clamp is greater than the maximum value in the defined range of the tension wire clamp performance assessment, then the simulation failure diagnosis assessment level of the hardware to be diagnosed corresponding to the performance assessment factor of the tension wire clamp is level three.

[0179] In order to facilitate the understanding of the above technical solution of the present invention, the following is a detailed description based on the actual test data of a certain type of tension clamp for high-voltage transmission lines as follows:

[0180] After conducting a corrosion characteristic test on the tension clamp, the corrosion characteristic data obtained specifically include: the thickness of the corrosion layer on the surface of the tension clamp is 0.5mm, the maximum depth of the corrosion pit of the tension clamp is 0.1mm, the surface resistance change rate of the tension clamp is 20%, the compensation factor of the thickness of the corrosion layer on the surface of the tension clamp is 1.0, the compensation factor of the maximum depth of the corrosion pit of the tension clamp is 1.5, the compensation factor of the surface resistance change rate of the tension clamp is 0.05, and the calculated corrosion characteristic assessment factor of the tension clamp is 1.053.

The electrical performance evaluation factor of the tension clamp is calculated to be 0.214.

[0184] Finally, based on the above test data, the corrosion characteristic assessment factor of the tension clamp, the vibration characteristic assessment factor of the tension clamp, the mechanical property assessment factor of the tension clamp and the electrical property assessment factor of the tension clamp are introduced into the performance constraint model of the tension clamp. Comprehensive analysis shows that the performance assessment factor of the tension clamp is 0.247. Since the performance assessment factor of the tension clamp falls within the defined range of the performance assessment of the tension clamp [0.1, 0.4], the performance test assessment level of the tension clamp is determined to be level two.
