Abstract
Description
Technical Field
[0001] This application relates to the field of insulator surface area measurement technology, and in particular to an insulator surface area measurement tool and measurement method. Background Technology
[0002] Regularly testing the salt and ash density values of insulators on transmission and distribution lines has become a routine part of power system maintenance. The test results of these values are crucial for mapping pollution areas. By mapping the pollution distribution of the power system, the configuration of external insulation for electrical equipment can be determined, and the pollution status of power lines can be understood, providing a basis for scientific maintenance and enabling early prevention and avoidance of flashover accidents on lines and electrical equipment.
[0003] The surface area of an insulator is an important technical parameter used in the detection of its salt density and ash density. Therefore, it is of great significance to achieve accurate measurement and calculation of the surface area of an insulator.
[0004] An insulator is an irregular object, which can be considered as a solid of revolution formed by rotating an irregular curve around an axis. Its surface area can be approximated as the sum of the lateral surface areas of multiple frustums or cylinders. Current methods for measuring the surface area of insulators mainly treat the insulator as an approximation of a cylinder or a combination of various regular three-dimensional shapes, establishing a three-dimensional approximate model. After measuring all the parameters of the approximate model, the surface area formulas of the corresponding three-dimensional shapes are substituted into tedious calculations. The entire process of calculating the surface area of insulators has strict requirements for the accuracy of parameter measurement and calculation. In particular, the fact that the insulator surface area calculation is based on an approximate three-dimensional model makes the results inherently prone to errors. Summary of the Invention
[0005] This application provides an insulator surface area measuring tool and method to solve the problem in the prior art that the insulator to be measured is approximated as a cylinder or a combination of various regular three-dimensional shapes, a three-dimensional approximate model is established, all parameters of the approximate model are measured, and then the surface area formula of the corresponding three-dimensional shape is substituted into the model for calculation. This method is cumbersome and the results have unavoidable errors.
[0006] On one hand, this application provides an insulator surface area measuring tool, the tool having a sheet-like structure, the sheet-like structure comprising: Main material layer; The distinguishing layer group is located on one side of the main material layer and has a different color from the surface of the insulator to be tested; The adhesive layer group is located on the other side of the main material layer and is used to bond with the surface of the insulator to be tested or the dividing layer group. The adhesive force between the adhesive layer group and the dividing layer group is greater than the adhesive force between the adhesive layer group and the surface of the insulator to be tested.
[0007] In one possible design, the main material layer is woven cotton fabric.
[0008] In one possible design, the distinguishing layer group includes a mirror layer, which is coated on the surface of the main material layer and has a smooth mirror surface.
[0009] In one possible design, the distinguishing layers include: Upper isolation layer, set on the upper surface of the main material layer; An upper adhesive layer is disposed on the upper surface of the upper isolation layer; An upper separation layer is disposed on the upper surface of the upper adhesive layer; The upper base layer is disposed on the upper surface of the upper separation layer.
[0010] In one possible design, the upper base layer comprises multiple sub-units, with adjacent sub-units separated by dividing lines that facilitate tearing. The dividing lines include several spaced-apart breakpoints.
[0011] In one possible design, the upper release layer is a polyethylene film; the upper adhesive layer includes rubber, polymethyl methacrylate, turpentine, tung oil, and high-density polyethylene; the upper release layer is a silicone oil layer; and the upper base layer is glassine paper.
[0012] In one possible design, the adhesive layer assembly includes: The lower isolation layer is set on the lower surface of the main material layer; A lower adhesive layer is disposed on the lower surface of the lower isolation layer; A lower separation layer is disposed on the lower surface of the lower adhesive layer; The lower base layer is disposed on the lower surface of the lower separation layer.
[0013] In one possible design, the lower separating layer is a polyethylene film; the lower adhesive layer includes rubber, polymethyl methacrylate, turpentine, tung oil, and high-density polyethylene; the lower separating layer is a silicone oil layer; and the lower base layer is kraft paper.
[0014] On the other hand, this application also provides a method for measuring the surface area of an insulator, using the insulator surface area measuring tool described above, the method comprising: Take a measuring tool and attach it to the surface of the insulator to be tested in sequence, with an overlapping area between adjacent measuring tools, until the entire surface of the insulator to be tested is covered by the measuring tool; Cut the measuring tool along the surface of the insulator to be tested; Lay the cut measuring tool flat on the kraft paper coated with silicone oil; The measuring tool, after being cut open, is divided into several regular planar geometric shapes. The area of each regular planar geometric shape is calculated, and then the summation is used to obtain the surface area of the insulator to be measured.
[0015] In one possible design, the area of the overlapping region is greater than or equal to one-quarter of the total area of any adjacent measuring tool.
[0016] The beneficial effects of this application are as follows: The insulator surface area measuring tool disclosed in this application utilizes the unique characteristics of its specific structure and materials. This allows it to completely cover an irregular insulator surface and then separate from the surface as a single unit, without altering the overall surface area of the measuring tool or leaving any sticky residue. By calculating the area of the separated measuring tool, the insulator surface area calculation is transformed from solving the surface area problem of an irregular three-dimensional model to solving the area problem of a planar figure. This significantly reduces the difficulty of the entire measurement and calculation process and effectively ensures the accuracy of the final result. Furthermore, because the materials used in this measuring tool are inexpensive and the method of use is simple and easy to learn, it effectively reduces the time and economic costs of this work.

[0021] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] The following is combined with Figures 1-4 This document describes the insulator surface area measuring tool provided in the embodiments of this application.
[0023] Reference Figure 1 As shown, the insulator surface area measuring tool provided in this application embodiment is a sheet-like structure with a certain size and regular shape. For example, the size of the sheet-like structure is 10cm*10cm. The insulator surface area measuring tool includes a mirror layer 101, a main material layer 102, a lower isolation layer 103, a lower adhesive layer 104, a lower separation layer 105, and a lower base layer 106.
[0024] Reference Figure 1 As shown, the mirror layer 101 is a thin film of polyethylene terephthalate (PET) coated on the upper surface of the main material layer 102. The mirror layer 101 itself is colored, and the color must be clearly distinguishable from the color of the ceramic insulator, chosen to allow the operator to easily identify the area of the insulator surface to which it has been adhered. In this embodiment, the mirror layer 101 is blue. Utilizing the high dimensional stability, good flexibility, and excellent surface smoothness of the PET film, when using this tool to measure the surface area of the insulator, the adhesion of the lower adhesive layer 104 to the mirror layer 101 is greater than its adhesion to the ceramic insulator. Furthermore, during the separation of the measuring tool from the insulator surface, it facilitates the complete separation of the measuring tool from the insulator surface while maintaining its overall dimensions.
[0025] The main material layer 102 is a specially made high-density woven cotton fabric. Utilizing its thin, soft, tensile-resistant, and non-deformable characteristics, it can completely conform to various curved surfaces when covering the insulator surface. When the measuring tool is separated from the insulator surface, the overall size of the measuring tool will not change due to the external force tearing off the adhesive layer 104, thus preventing errors in the measured value of the insulator surface area from the actual value.
[0026] The lower isolation layer 103 is a polyethylene film sandwiched between the main material layer 102 and the lower adhesive layer 104. Its function is to prevent substances in the lower adhesive layer 104 from penetrating into the main material layer 102, thereby avoiding affecting the performance of the lower adhesive layer 104.
[0027] The lower adhesive layer 104 is an adhesive material sandwiched between the lower separating layer 103 and the lower separating layer 105. The main components of the lower adhesive layer 104 include rubber, polymethyl methacrylate, turpentine, tung oil, and high-density polyethylene. By adjusting the proportions of these components, it achieves the following characteristics: 1) viscosity sufficient for adhesion and fixation on the insulator surface within a certain time; 2) easy peeling from the insulator surface; 3) no residue left on the insulator surface after peeling; 4) greater adhesion strength when bonded to the mirror layer 101 than when bonded to the insulator surface.
[0028] The lower release layer 105 is a silicone oil layer sandwiched between the lower adhesive layer 104 and the lower substrate layer 106. The lower release layer 105 is applied onto the lower substrate layer 106 by coating and serves the following functions: 1) to protect the lower adhesive layer 104 from weakening its adhesion before it is used; 2) to allow easy peeling from the lower adhesive layer 104 when it is being used.
[0029] The lower base layer 106 is a layer of kraft paper, which supports the lower release layer 105 and facilitates the separation of the lower release layer 105 from the lower adhesive layer 104.
[0030] Measurement method for measuring the surface area of an insulator using the insulator surface area measuring tool described in the above embodiments: 1. Clean and dry the surface of the insulator 300 whose surface area needs to be measured.
[0031] 2. Take a measuring tool. Depending on the size of the insulator surface being measured, decide whether to cut the measuring tool to the required size. Then peel off the lower base layer 106 with the lower separation layer 105 and attach it along the surface of the insulator.
[0032] 3. Take another measuring tool. Depending on the size of the insulator surface being measured, decide whether to cut the single measuring tool to the required size. Then peel off the lower base layer 106 with the lower separation layer 105, and continue to regularly paste the other measuring tool along the insulator surface. There should be an overlap area between the two measuring tools during pasting. When all are pasted, ensure that the area of the overlap area of each measuring tool is not less than 1 / 4 of its original or cut mirror layer 101 area. This further ensures that the integrity of the measuring tool as a whole is not compromised during the separation process after the entire insulator surface is covered by the measuring tool to form a single measuring tool.
[0033] 4. Repeat step 3 until the insulator surface is completely covered by the measuring tool and forms a whole.
[0034] 5. Reference Figure 4 Using a marker, draw a cutting path on the outermost surface (mirror layer 101) of the formed measuring tool, with the insulator suspended vertically as the standard, and following the path that runs longitudinally through the entire outer surface of the measuring tool.
[0035] 6. At one end of the marked path, use scissors to cut the measuring tool along the marked path. While cutting, separate the measuring tool from the surface of the insulator, so that the measuring tool changes from a three-dimensional attached state to an approximately planar state.
[0036] 7. Lay the separated measuring tool with the adhesive layer 104 side flat on a piece of kraft paper with a sufficiently large area coated with silicone oil.
[0037] 8. Divide the approximately planar measuring tool into several regular planar geometric shapes using a marker and scissors. Calculate the surface area of each regular geometric shape and then sum them to obtain the surface area of the insulator being measured.
[0038] Reference Figure 2 As shown, the insulator surface area measuring tool in this embodiment is a sheet-like structure with a certain size and regular shape. The size of the sheet-like structure is 12cm*12cm. The insulator surface area measuring tool includes a main material layer 102, an upper insulating layer 110, an upper adhesive layer 109, an upper separating layer 108, an upper base layer 107, a lower insulating layer 103, a lower adhesive layer 104, a lower separating layer 105, and a lower base layer 106.
[0039] Reference Figure 2 As shown, the upper base layer 107 is a layer of glassine paper. Utilizing its dense, soft, and thin characteristics, the surface area measuring tool can still perfectly conform to various curved surfaces when covering the insulator surface without removing the upper base layer 107, effectively reducing measurement errors. The upper base layer 107 itself is colored, and the color must be clearly distinguishable from the color of the porcelain insulator to help the operator clearly identify the area of the insulator surface that has been covered. In this embodiment, the upper base layer 107 is blue.
[0040] Reference Figure 3As shown, the upper base layer 107 includes multiple sub-units, and adjacent sub-units are separated by dividing lines that facilitate tearing. The dividing lines include several spaced-apart breakpoints. For example, the upper isolation layer includes multiple equally divided squares so that when two insulator surface area measuring tools overlap on the insulator surface, the upper base layer 107 of the tool on the lower layer of the overlapping part can be torn off, while the upper base layer 107 of the tool on the upper layer of the overlapping part and the upper base layer 107 of the non-overlapping part of the two tools are not torn off.
[0041] The upper release layer 108 is a silicone oil layer sandwiched between the upper adhesive layer 109 and the upper substrate layer 107. The upper release layer 108 is coated on the surface of the upper substrate layer 107 and serves the following functions: 1) to protect the upper adhesive layer 109 from weakening its adhesion before it is used; 2) to allow easy peeling from the upper adhesive layer 109 when it is being used.
[0042] The upper adhesive layer 109 is a layer of adhesive material sandwiched between the upper release layer 110 and the upper separation layer 108. The main components of the upper adhesive layer 109 include rubber, polymethyl methacrylate, turpentine, tung oil, and high-density polyethylene. By adjusting the proportions of these components, it achieves the following characteristics: 1) higher adhesion than the lower adhesive layer; 2) durable and stable adhesion; 3) significantly increased adhesive strength when bonded to the lower adhesive layer.
[0043] The upper isolation layer 110 is a polyethylene film sandwiched between the upper adhesive layer 109 and the main material layer 102. Its function is to prevent substances in the upper adhesive layer 109 from penetrating into the main material layer 102, thereby affecting the performance of the upper adhesive layer 109.
[0044] The main material layer 102 is a specially made high-density woven cotton fabric. Utilizing its thin, soft, tensile-resistant, and non-deformable characteristics, it can completely conform to various curved surfaces when covering the insulator surface. When the measuring tool is separated from the insulator surface, the overall size of the measuring tool will not change due to the external force tearing off the adhesive layer 104, thus preventing errors in the measured value of the insulator surface area from the actual value.
[0045] The lower isolation layer 103 is a polyethylene film sandwiched between the main material layer 102 and the lower adhesive layer 104. Its function is to prevent substances in the lower adhesive layer 104 from penetrating into the main material layer 102, thereby affecting the performance of the lower adhesive layer 104.
[0046] The lower adhesive layer 104 is a layer of adhesive material sandwiched between the lower separator layer 103 and the lower release layer 105. The main components of the lower adhesive layer 104 include rubber, polymethyl methacrylate, turpentine, tung oil, and high-density polyethylene. By adjusting the proportions of these components, it achieves the following characteristics: 1) viscosity sufficient for adhesion and fixation on the insulator surface within a certain time; 2) easy peeling from the insulator surface; 3) no residue left on the insulator surface after peeling.
[0047] The lower release layer 105 is a silicone oil layer sandwiched between the lower adhesive layer 104 and the lower substrate layer 106. The lower release layer 105 is applied onto the lower substrate layer 106 by coating and serves the following functions: 1) to protect the lower adhesive layer 104 from weakening its adhesion before it is used; 2) to allow easy peeling from the lower adhesive layer 104 when it is being used.
[0048] The lower base layer 106 is a layer of kraft paper, which supports the lower release layer 105 and facilitates the separation of the lower release layer 105 from the lower adhesive layer 104.
[0049] Measurement method for measuring the surface area of an insulator using the insulator surface area measuring tool described in the above embodiments: 1. Clean and dry the surface of the insulator whose surface area needs to be measured.
[0050] 2. Take a measuring tool. Depending on the size of the insulator surface being measured, decide whether to cut the measuring tool to the required size. Then peel off the lower base layer 106 with the lower separation layer 105 and attach it along the surface of the insulator.
[0051] 3. Take another measuring tool. Depending on the size of the insulator surface being measured, decide whether to cut the single measuring tool to the required size. Then peel off the lower base layer 106 with the lower separation layer 105, and continue to regularly attach the other measuring tool along the insulator surface. There should be an overlap between the two measuring tools during attachment. When all are attached, ensure that the final overlapping area of each measuring tool is not less than 1 / 4 of its original or cut lower base layer 106 area. This further ensures that the integrity of the measuring tool as a whole is not compromised during the separation process after the insulator surface is completely covered by the measuring tool. The upper base layer 107 of the non-overlapping parts of the two measuring tools should be retained and not peeled off to facilitate subsequent measurement steps.
[0052] 4. Repeat step 3 until the insulator surface is completely covered by the measuring tool and forms a whole.
[0053] 5. Reference Figure 4Using a marker, draw a cutting path on the outermost surface (upper base layer 107) of the formed measuring tool, with the insulator suspended vertically as the standard, and following the path that runs longitudinally through the entire outer surface of the measuring tool.
[0054] 6. At one end of the marked path, use scissors to cut the measuring tool along the marked path. While cutting, separate the measuring tool from the surface of the insulator, so that the measuring tool changes from a three-dimensional attached state to an approximately planar state.
