Description

Technical Field

[0001] The present application relates to the technical field of electric power fittings, and in particular to a method and system for evaluating the quality of the hot-dip galvanized layer on the surface of fittings after a wildfire. Background Art

[0002] Overhead transmission lines are a crucial physical vehicle for energy allocation and power supply in the new power system. As the new power system becomes a new engine for construction, long transmission distances and wide spatial spans have become prominent characteristics of overhead transmission lines. These lines are subject to increasingly complex and variable operating conditions, with a significant increase in the proportion of lines passing through fire-prone areas such as mountainous areas and forests. Wildfires have become a major natural disaster contributing to transmission line failures.

[0003] Forest fires in hot or dry climates spread rapidly, burn at high temperatures, and last for a long time. The flame's center can reach a maximum temperature of 1200°C, its edge can reach 1100°C, the hot flue gas temperature can exceed 520°C, and the flame column can reach a maximum height of 20-30 meters. Overhead transmission line hardware is mostly made of carbon structural steel or alloy structural steel, with steel parts generally treated with hot-dip galvanizing for corrosion protection. Hot-dip galvanizing is susceptible to severe oxidation when exposed to high temperatures, causing the zinc coating to become brittle and lose its protective effect. After a wildfire, it is particularly important to evaluate the quality of the zinc coating on the surface of hardware. Hardware that does not meet quality standards must be replaced, while hardware with degraded zinc coatings requires regular anti-corrosion maintenance. Hardware that meets quality requirements does not require regular anti-corrosion maintenance.

[0004] Currently, testing for the surface corrosion of the galvanized coating after wildfires involves macroscopic examination, laboratory composition analysis, and microstructural analysis. This macroscopic assessment of the corrosion status of the galvanized coating on transmission line fittings relies primarily on the operational experience of line workers, which can lead to arbitrary and blind approaches to corrosion protection. Microscopic analysis using precision laboratory instruments can accurately assess the corrosion status of the galvanized coating, but in practice, on-site sampling and re-sampling of the fittings is required, which is labor-intensive, time-consuming, and inefficient in providing rapid results. Summary of the Invention

[0005] The purpose of this application is to provide a fast, convenient and accurate method for evaluating the quality of the hot-dip galvanized layer on the surface of hardware after a wildfire failure, so as to solve the problems of non-standardization, objectivity, long cycle and large workload of existing detection methods.

In particular, based on the Fe / Zn value of the zinc coating surface, the zinc coating thickness test is added to obtain the thickness of the individual zinc coating and the overall zinc coating thickness. The zinc coating thickness evaluation index determined by the correspondence between the minimum zinc coating thickness of the hardware and the local atmospheric corrosion level is combined to obtain the quality evaluation results of the hot-dip galvanized layer on the surface of the hardware. The triple indicators of thickness, Fe / Zn value, and corrosion level are used to comprehensively evaluate the quality of the zinc coating, avoiding the limitations of a single indicator. The zinc coating thickness requirements are adjusted according to the actual service environment to improve the durability of the hardware under specific corrosion conditions. By comparing with the atmospheric corrosion level standard, it is intuitively judged whether the zinc coating meets the use requirements and reduce the risk of quality disputes. Through Fe / Zn value analysis, insufficient coating purity or substrate corrosion risks can be discovered in advance to avoid large-scale failures in the later stage. The zinc coating thickness is reasonably selected according to the corrosion level to avoid cost waste caused by excessive galvanizing. This method establishes a scientific and systematic quality evaluation system for hot-dip galvanizing coatings by combining coating thickness testing, Fe / Zn analysis, and atmospheric corrosion level matching. This not only improves the corrosion resistance of hardware but also provides a replicable and scalable quality evaluation paradigm. This evaluation system enables rapid, convenient, and accurate assessment of the surface quality of galvanized coatings on hardware after wildfires, addressing the issues of existing testing methods, such as non-standardization, objectivity, long processing times, and high workload.

[0032] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application. For the step numbers in the following embodiments, they are provided only for the convenience of explanation and are not intended to limit the order of the steps. The order of execution of the steps in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0033] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0034] This application aims to evaluate the quality of the zinc coating on the surface of hardware after wildfire failures. It proposes an evaluation system that combines three indicators: the appearance of the zinc coating, the Fe / Zn value of the zinc coating surface, and the thickness of the zinc coating. Specifically, it includes: S1, perform appearance inspection on the zinc coating on the surface of the hardware after the wildfire failure, and proceed to S2 after passing the inspection; S2, testing the Fe / Zn value of the galvanized layer surface, and based on the quantitative relationship between the Fe / Zn value and the corrosion degree, proceed to S3 after judging that the corrosion degree is qualified; S3, the galvanized layer thickness is tested to obtain the thickness of the individual galvanized layer and the overall galvanized layer thickness, and the galvanized layer thickness evaluation index is determined by combining the correspondence between the minimum galvanized layer thickness of the hardware and the local atmospheric corrosion level to obtain the quality evaluation result of the hot-dip galvanized layer on the hardware surface.

[0035] Furthermore, the present invention can use a portable X-ray fluorescence spectrometer to detect the composition of the zinc coating and obtain the Fe / Zn ratio, which is a convenient and fast non-destructive test. The magnetic method can also be used to measure the thickness of the zinc coating, which is also a non-destructive test. The combination of the two can quickly and accurately analyze the surface quality of the zinc coating. This solves the problem of large laboratory analysis workload, long cycle time, and the inability to quickly provide results.

[0036] More specifically, the present application provides a method for evaluating the quality of hot-dip galvanized layer on the surface of hardware after a wildfire. The method is an evaluation system consisting of three evaluation indicators, such as Figure 1 The figure shows the appearance of the galvanized layer, the Fe / Zn value of the galvanized layer surface, and the thickness of the galvanized layer. It also provides the quantitative relationship between the Fe / Zn value of the galvanized layer of the hardware after a wildfire and the degree of corrosion; and the quantitative relationship between the minimum thickness of the galvanized layer on the surface of the hardware after a wildfire and the corresponding galvanized layer quality. The specific technical solution is as follows: Indicator 1: Appearance of galvanized layer; The galvanized layer should be continuous and smooth, firmly and evenly adhered to the plated parts, without peeling or flaking. Zinc leakage spots with a diameter of less than 0.5mm are allowed on the local surface. There should be no concentrated zinc-free areas, nodules and ripples on the galvanized surface. The total area of ​​dispersed zinc-free areas, nodules and ripples should meet the following requirements: 1) For general hardware, it should not exceed 0.5% of the total area of ​​the plated part; 2) Large hardware (such as voltage-sharing shielding rings, large connecting plates or those with a surface area exceeding 2000cm 2 The metal fittings) should not exceed 0.1% of the total plated area.

[0037] Indicator 2: Fe / Zn value of the galvanized layer surface; There is a clear correlation between the corrosion state of the hot-dip galvanized layer and the Fe / Zn ratio on the galvanized layer surface. That is, the larger the Fe / Zn value, the more severe the damage to the galvanized layer of the hardware and the greater the zinc layer consumption. Further experimental research revealed a quantitative correlation between the corrosion state of the galvanized layer and the Fe / Zn ratio. Specifically, when the Fe / Zn mass ratio is greater than 10%, the galvanized layer has reached a severe corrosion level and no longer provides protection to the substrate, requiring timely anti-corrosion treatment or replacement. When the Fe / Zn mass ratio is less than or equal to 4%, the corrosion state of the galvanized layer is relatively mild (mild corrosion) and still provides good protection to the substrate. When the Fe / Zn mass ratio is between 4% and 10%, the corrosion state of the galvanized layer has reached a moderate corrosion level. The galvanized layer still has some protective effect, but the galvanized layer has been significantly thinned and multiple fine cracks have appeared on the surface, requiring increased inspection of the hardware.

[0038] It can be seen that the Fe / Zn ratio test results play a vital role in the quality evaluation of the galvanized layer. The Fe / Zn value test steps are as follows: 1) Select the number of inspection points according to the size of the hardware to be inspected. For smaller hardware (such as U-shaped rings, ball head hanging rings, etc.), 4 to 6 inspection points are required, preferably 4 inspection points. For hardware with a larger surface area (equalizing shielding rings, large connecting plates or hardware with a surface area of ​​more than 2000cm 2 For hardware), 6 to 8 inspection points need to be selected, with 6 inspection points being preferred.

[0039] 2) Test the Fe and Zn content at the detection points and calculate the Fe / Zn ratio of each detection point; take the average value of the Fe / Zn ratio of all detection points to obtain the Fe / Zn ratio.

[0040] 3) The Fe / Zn ratio is the ratio of the mass percentage of the Fe element to the mass percentage of the Zn element.

[0041] 4) Determine the corrosion status of the galvanized layer of the hardware based on the obtained Fe / Zn ratio; when the Fe / Zn ratio of the galvanized layer of the hardware is greater than a, the galvanized layer is severely corroded and needs to be replaced in time; when the Fe / Zn ratio of the galvanized layer of the hardware is between a and b, the galvanized layer is moderately corroded and requires regular anti-corrosion maintenance; when the Fe / Zn ratio of the galvanized layer of the hardware is less than or equal to a, the galvanized layer is slightly corroded and the galvanized layer thickness test is required, where a and b are constants, a<b.

[0042] For example: when the Fe / Zn ratio of the galvanized layer of the hardware is greater than 10%, the galvanized layer is severely corroded and needs to be replaced in time; when the Fe / Zn ratio of the galvanized layer of the hardware is between 4% and 10%, the galvanized layer is moderately corroded and requires regular anti-corrosion maintenance; when the Fe / Zn ratio of the galvanized layer of the hardware is less than or equal to 4%, the galvanized layer is slightly corroded and the galvanized layer thickness test is required.

[0043] In the above detection method, preferably, a portable X-ray fluorescence spectrometer is used to detect the Fe and Zn mass contents of the zinc coating.

[0044] Indicator three: galvanized layer thickness; The corrosion level of the hardware service environment is determined based on the service environment of the hardware, including the humidity time of the atmosphere, the dust content in the air, the sulfur compound content in the air, and the chloride content in the air, combined with the average annual corrosion rate of standard metal parts. The corrosion level of the hardware service environment is graded in accordance with the standard GB / T19292.1-2018 "Classification of Corrosion Atmospheres of Metals and Alloys", and is divided into five corrosion levels: C1, C2, C3, C4, and C5. The corrosion level is divided into five levels: C1, C2, C3, C4, and C5, and the corrosivity increases in sequence.

[0045] For steel fittings, the evaluation index of zinc coating thickness is differentiated according to the thickness of the plated parts: When the thickness of the plated part is ≥6mm: the minimum thickness of the individual zinc coating is 50μm for grades C1 and C2, 70μm for grade C3, 90μm for grade C4, and 150μm for grade C5. The minimum overall zinc thickness is 65μm for grades C1 and C2, 85μm for grade C3, 115μm for grade C4, and 180μm for grade C5.

[0046] When the plated thickness is 3mm≤and the plated thickness is less than 6mm: the minimum thickness of the individual zinc coating is 40μm for grades C1 and C2, 55μm for grade C3, 70μm for grade C4, and 90μm for grade C5. The minimum overall zinc thickness is 55μm for grades C1 and C2, 70μm for grade C3, 86μm for grade C4, and 110μm for grade C5.

[0047] For cast iron fittings, the evaluation index of zinc coating thickness is also differentiated according to the thickness of the plated parts: When the thickness of the plated part is ≥6mm: the minimum thickness of the individual zinc coating is 50μm for grades C1 and C2, 70μm for grade C3, 90μm for grade C4, and 150μm for grade C5. The minimum overall zinc thickness is 60μm for grades C1 and C2, 80μm for grade C3, 110μm for grade C4, and 170μm for grade C5.

[0048] When the thickness of the plated part is less than 6mm: the minimum thickness of the individual zinc coating is 40μm for grades C1 and C2, 60μm for grade C3, 70μm for grade C4, and 90μm for grade C5. The minimum overall zinc thickness is 50μm for grades C1 and C2, 70μm for grade C3, 80μm for grade C4, and 110μm for grade C5.

[0049] The details are shown in Table 1 below.

[0050] Table 1 Atmospheric corrosion classification

[0051] The evaluation index of the galvanized layer thickness is determined according to the corrosion level of the hardware service environment. The evaluation index of the galvanized layer thickness of the hardware under various corrosion environment conditions is shown in Table 2.

[0052] Table 2 Minimum thickness of zinc coating on metal fittings (μm)

[0053] That is, the higher the corrosion level, the higher the requirement for the thickness of the zinc coating to ensure that the hardware can operate stably and long-term in a harsh corrosive environment. At the same time, the thickness of the plated part is also an important factor affecting the evaluation index of the zinc coating thickness. The thicker the plated part, the thicker the required zinc coating thickness.

[0054] The above empirical data takes into account various factors, such as plated component thickness and corrosion level, providing flexible options for corrosion protection of hardware under different conditions. The thickness of the zinc coating can be adjusted according to the specific environment, such as increasing the coating thickness to improve corrosion resistance under high corrosion levels (C5). This is because coating thickness is one of the key factors determining its corrosion resistance. Thicker coatings can provide longer-term protection, especially in highly corrosive environments. The empirical data determines different coating thickness requirements based on plated component thickness and corrosion level. For example, for steel hardware with a plated component thickness ≥6mm, the minimum individual zinc coating thickness is required to reach 150mm and the minimum overall zinc thickness to reach 180mm under C5 level to ensure corrosion resistance of the hardware within its expected lifespan. Environments with different corrosion levels have different corrosion rates for the coating. The empirical data of this example takes these environmental factors into account and provides targeted guidance for corrosion protection of hardware in different environments.

[0055] Among them, this embodiment also provides a method for detecting the thickness of the zinc coating, and the specific steps are as follows: 1) Randomly select samples from metal fittings with a zinc coating Fe / Zn ratio of less than or equal to 4%; 2) The measuring points should be randomly and evenly distributed on the entire zinc layer surface of the test piece. If the size of the workpiece allows, the measuring points should not be in the area less than 10mm from the edge or the flame-cut surface; 3) For each hardware sample, measure the thickness at 5-8 measuring points and take the arithmetic mean as the thickness of the single galvanized layer of the sample.

[0056] 4) If it is a batch sample, calculate the overall zinc thickness of the batch of hardware samples.

[0057] 5) The thickness of the single zinc coating is the arithmetic mean of the zinc coating thicknesses measured on the zinc coating surface of a single specimen a specified number of times.

[0058] 6) The overall zinc thickness is the arithmetic mean of the thickness of the individual zinc coatings of all sampled test pieces of a batch of galvanized parts.

[0059] The thickness of the zinc layer is preferably measured by a magnetic method, which is a non-destructive testing method.

[0060] 7) Compare the individual galvanized layer thickness and overall galvanized layer thickness obtained in steps 3) and 4) with the local atmospheric corrosion level and the minimum galvanized layer thickness of the hardware in Table 2. If the minimum galvanized layer thickness in Table 2 is met, the hardware can continue to serve. If it does not meet the minimum galvanized layer thickness in Table 2, regular anti-corrosion maintenance is required.

[0061] The principle of zinc coating thickness testing is to directly measure the thickness of the zinc coating on the surface of individual hardware using a magnetic thickness gauge, eddy current thickness gauge, or metallographic microscope. A batch of hardware is sampled and tested, and parameters such as average thickness and minimum thickness are calculated to assess the overall zinc coating quality.

[0062] The atmospheric corrosion level is matched to the galvanized layer thickness. The corresponding minimum galvanized layer thickness requirement is determined based on the local atmospheric corrosion level. By comparing the minimum galvanized layer thickness of the hardware with the standard requirements, its corrosion resistance is evaluated to see whether it meets the standard.

[0063] Compliance of coating thickness: coating thickness ≥ minimum requirement, indicating that basic corrosion resistance is met; combined with the local atmospheric corrosion level, the galvanized layer thickness requirement is dynamically adjusted to ensure the long-term reliability of the hardware in the service environment.

[0064] Based on the above scheme, the advantages of galvanized layer thickness detection in the service environment of hardware are analyzed as follows: 1. Precisely adapted to the corrosive environment: According to the GB / T19292.1-2018 standard, corrosion levels C1-C5 are categorized by quantitative environmental parameters (humidity duration, dust, sulfides, and chlorides). The required zinc coating thickness strictly corresponds to the corrosion level (Table 2). For example, level C5 (extremely high corrosion) requires a thicker zinc coating to avoid wasting resources due to insufficient or excessive galvanizing, achieving an optimal balance between protection and cost.

[0065] 2. Extending the service life of hardware: The zinc coating slows down base metal corrosion through sacrificial anode protection, and thickness testing directly verifies its protective capabilities. Based on standard corrosion rates and zinc coating thickness, the expected service life of hardware in specific environments can be estimated to guide maintenance planning.

[0066] 3. Standardized quality control: GB / T19292.1-2018 and Table 2 provide internationally recognized testing standards, eliminating subjective judgments and improving the comparability of test results. Test data feedback allows optimization of galvanizing process parameters (such as current density and galvanizing time) to ensure coating uniformity and density.

[0067] 4. Avoid frequent replacements due to excessively thin coatings (high hidden costs) or material waste due to excessively thick coatings. Regular inspections can identify localized coating loss in advance, allowing for targeted repairs and avoiding the economic losses caused by large-scale corrosion failures.

[0068] 5. Use non-destructive technologies such as magnetic thickness gauges and eddy current thickness gauges for rapid and accurate measurement without affecting the structural integrity of the hardware. Digitally record the distribution of coating thickness, providing a basis for quality traceability and accountability, in compliance with ISO quality management system requirements.

[0069] If service environment parameters change (e.g., increased chloride salt content in coastal areas), the protection level can be reassessed by retesting the coating thickness, allowing timely adjustments to maintenance strategies. Table 2 shows thickness standards corresponding to different corrosion levels, applicable to diverse industrial scenarios such as power transmission, railways, and chemical industries.

[0070] Therefore, zinc coating thickness testing directly links environmental corrosion with protective performance through standardized and quantified methods, making it scientific, economical, and practical. Its core advantage lies in minimizing hardware lifecycle costs and maximizing reliability through precise protection matching, making it particularly suitable for long-term corrosion protection management in harsh industrial environments.

[0071] In order to better understand the present application, the present application is further described below with reference to the accompanying drawings and specific embodiments.

[0072] Taking the U-shaped ring of a connecting hardware after a wildfire as an example, a method for evaluating the quality of the zinc coating on the surface of the hardware after a wildfire includes the following steps: 1. Inspection of appearance index of galvanized layer: After the fire, the zinc coating on the U-shaped ring of the connecting hardware was smooth and continuous, firmly and evenly adhered to the plated part, without any peeling or flaking. Therefore, the appearance of the zinc coating was qualified.

[0073] 2. Detection of Fe / Zn value index on the surface of galvanized layer; 1) Due to the small size of the U-shaped ring of the connecting hardware, four test points were selected to test the composition of the galvanized layer; 2) Use a portable spectrometer to detect the surface composition of the test points of the tested hardware and record the test results, as shown in Table 3.

[0074] Table 3 Composition of the zinc coating at four test points on the U-shaped metal fitting (wt.%; other elements not listed)

[0075] 3) The Fe / Zn value was calculated and the average Fe / Zn value at the four detection points was 1.57wt%; 4) When the Fe / Zn ratio is less than or equal to 4%, the galvanized layer is slightly corroded and the galvanized layer thickness test is required.

[0076] 3. Galvanized layer thickness index detection; 1) Randomly select samples from U-shaped ring samples with Fe / Zn ratio less than or equal to 4%; 2) The measurement points should be randomly and evenly distributed on the entire zinc layer surface of the test piece, and the measurement points should not be made in the area less than 10 mm from the edge.

[0077] 3) The thickness of the zinc coating of the U-shaped ring sample was tested by the magnetic method. Five measuring points were selected and their arithmetic mean was taken as the thickness of the single zinc coating of the sample. The measured zinc coating thickness values ​​are shown in Table 4.

[0078] Table 4 Thickness of zinc coating at five inspection points of hardware U-shaped ring (μm)

[0079] 4) The thickness of the U-shaped ring tested is 20 mm, and the material is 35CrMo steel. The atmospheric corrosion level of the line is C3. According to the minimum thickness requirement of the galvanized layer in Table 2, the thickness of the galvanized layer of the U-shaped ring should be greater than or equal to 70 μm.

[0080] 5) The thickness of the single zinc coating obtained in step 3) is 91 μm, which meets the minimum zinc coating thickness value in Table 2. Therefore, the conclusion is that the hardware can continue to serve without the need for hardware anti-corrosion maintenance.
