For ease of understanding, referring to fig. 1, an embodiment of a method for detecting defects of a power transmission cable clamp based on a coating provided in the present application includes:
Further, step 101 includes:
fusing first preset amount of orange grease and ethyl acetate to obtain a coating matrix;
adding a second preset amount of silver potassium germanate, lithium germanate, indolopyrrolone, dimethyl azobenzoate and nickel flash powder into the coating matrix, and stirring uniformly to obtain a thermal fusion agent, wherein the thermal fusion agent comprises a heat-sensitive fluorescent agent and a thermochromic fuel;
and adding a third preset amount of nano silicon chip into the thermal fusion agent to obtain the mixed coating, wherein the nano silicon chip is used as a color-changing response seasoning.
In this embodiment, the mixed paint is prepared from a plurality of preset chemical agents, and mainly comprises 10-15 parts of silver potassium germanate, 5-9 parts of lithium germanate, and indolopyrene (C) 14 H 8 N 2 O 2 ) 18-35 parts of dimethyl azobenzoate (C) 16 H 10 N 2 O 2 ) 26-42 parts of nickel flash powder 14-20 parts of nano silicon chip 25-41 parts of ethyl acetate 15-30 parts of orange grease 20-40 parts of orange grease, wherein the parts refer to the mass ratio of various reagents. In this embodiment, only the reference ranges of the first preset quantity, the second preset quantity and the third preset quantity are given, and the specific configuration quantity can be adjusted based on the actual requirement, which is not limited herein; it will be appreciated that adjustment of the proportions of the different agents may give the hybrid coating different functional emphasis, such as degree of coloration, corrosion protection, water resistance, viscosity, etc. For example, 12 parts of silver potassium germanate, 6 parts of lithium germanate, 20 parts of indolopyrrolone, 32 parts of dimethyl azobenzoate, 16 parts of nickel flash powder, 29 parts of nano silicon chip, 21 parts of ethyl acetate and 28 parts of orange grease can be prepared into a mixed paint.
In the preparation process, the fused orange grease and ethyl acetate are used as a coating matrix, and on the basis, heat-sensitive fluorescent agents such as silver potassium germanate, lithium germanate, indolopyrrolone, dimethyl azobenzoate, nickel flash powder and the like and thermochromic fuel are added to be stirred, so that a heat fusion agent can be obtained; and adding the thermal fusion agent into the nano silicon chip, stirring and grinding to obtain the mixed paint. In order to facilitate the subsequent brushing, after the mixed paint is prepared in this embodiment, the viscosity of the paint needs to be adjusted by continuously stirring, and the mixed paint is thick and can not flow after stirring, so that the paint is in an optimal brushing state.
Lithium germanate (Li 2 GeO 3 ) White powder, and automatic response of changing color when heating in power transmission wire clampThe paint is used as a heating catalyst to accelerate the heating reaction of the paint on the power transmission wire clamp. Meanwhile, the lithium germanate has good electrical property and high temperature resistance, and can improve the heat resistance and the electrical insulation property of the power transmission wire clamp. In addition, the lithium germanate can also improve the flow and viscosity of the paint and improve the coating property and adhesive force of the paint.
Silver potassium germanate (Ag) 4 K 4 Ge 4 O 12 ) The temperature-sensitive film material is white powder, odorless and tasteless, the purity is more than or equal to 99%, the moisture content is less than or equal to 1%, the temperature-sensitive film material can exhibit an automatic color-changing effect of overlapping different colors, and the temperature-sensitive film material can be used for exhibiting the change of the surface temperature of a conductor. In the power transmission wire clamp, the function of silver potassium germanate is to detect whether the surface temperature of the clamp is too high, when the surface temperature of the clamp reaches a certain temperature, the silver potassium germanate can automatically change color, so that a warning signal is sent to an electric engineer to remind the electric engineer to timely process or replace the wire clamp, and the safe operation of a power transmission line is ensured.
Indolopyrrolone (C) 14 H 8 N 2 O 2 ) Is a colorless or light-colored heat-sensitive fluorescent dye which can change the color and sensitivity of the heating automatic color-changing paint. When the surface temperature of the coating exceeds a certain temperature, the indolopyrrolone can undergo a chemical reaction, so that the coating changes color, and the power transmission wire clamp is indicated to have a possible heating phenomenon.
Dimethyl azobenzoate (C) 16 H 10 N 2 O 2 ) The color of the azobenzoic acid dimethyl ester is changed according to the change of temperature, the azobenzoic acid dimethyl ester has better chemical stability and durability, and the heating automatic color-changing response paint can be ensured not to fade or fade for a long time.
Nickel flash powder is a substance with fluorescent properties and can convert energy into visible light signals. In the novel automatic color-changing response coating for heating the power transmission wire clamp, the nickel type flash powder has the effects that when the power transmission wire clamp heats, heat generated after heating is absorbed and converted into fluorescence, and the color of a coating on the surface of the power transmission wire clamp changes accordingly, so that the monitoring and early warning of the temperature change of the power transmission wire clamp are realized. Specifically, when the temperature of the power transmission wire clamp is increased, the nickel type flash powder can emit a strong fluorescent signal, and the coating can gradually change from white to yellow and orange, so that workers are reminded to strengthen monitoring and maintenance of the power transmission wire clamp.
The nanometer silicon chip is a nanometer silicon chip with the size of 25-50nm, and the function of automatic color change is realized mainly through the special optical property and chemical property in the novel automatic color change response coating for the heat generation of the power transmission cable clamp. In particular, the nanosilicon chip has reversible optical response characteristics, and when being stimulated by heating force, electrons in a lattice structure of the nanosilicon chip undergo energy level transition, so that the reflected spectrum of the nanosilicon chip changes, and color changes are generated. Meanwhile, the nanometer silicon chip has higher thermal stability and chemical stability, can keep the color change effect in various environments, and can not be influenced by external environments to lose the function of automatic color change. Therefore, the nano silicon chip is one of key components for realizing the automatic color changing function of the novel power transmission wire clamp heating automatic color changing coating.
The ethyl acetate is an ethyl acetate organic solvent, so that the drying and curing process of the coating is accelerated, meanwhile, the ethyl acetate has better dissolving capacity and volatility, the fluidity of the coating can be improved, the coating can be more uniformly attached to the surface of a power transmission wire clamp, and the adhesive force and the wear resistance of the coating are improved. In addition, the ethyl acetate can also play a role in adjusting the viscosity of the paint, so that the paint is easier to construct and residual pollutants are reduced.
The orange fat is an orange plant oil, and is extracted from subcutaneous horny layer of orange. The orange grease plays roles of mixing, diluting, processing and adjusting in the novel automatic color-changing response paint for the heating of the power transmission wire clamp, can improve the performance and quality of the paint, and improves indexes such as coating property, adhesiveness, wear resistance, weather resistance and the like. In addition, the orange grease can also increase the glossiness and softness of the coating, so that the coating is more uniform, finer and smoother and has a stereoscopic impression.
And 103, brushing the mixed paint on adjacent wire fittings of the wire clamp to obtain the color of the wire paint, wherein the second brushing range comprises a wire crimping pipe and a jumper wire part.
It should be noted that, both the wire clamp of the target transmission line and the wire clamp adjacent to the wire fitting need to be painted, the surface of the device is fully painted with the mixed paint without leaving any gap, so that the detection accuracy can be ensured. In addition, the coating range adjacent to the wire fitting is a wire crimping pipe and a jumper wire part, the length is 20-35cm, and the wire crimping pipe and the jumper wire part can be specifically set according to actual conditions and are not limited herein.
And 104, comparing the color of the wire clamp coating with the color of the wire coating based on a preset coating chromaticity table to obtain the defect grade of the power transmission wire clamp.
Further, step 104 includes:
respectively determining the color-changing temperatures of the wire clamp and adjacent wire fittings according to the positions of the wire clamp paint color and the wire paint color in a preset paint chromaticity meter;
and analyzing the defect grade of the power transmission wire clamp according to the color-changing temperatures respectively corresponding to the wire clamp and the adjacent wire fitting in a comparison mode to obtain the defect grade of the power transmission wire clamp.
In this embodiment, the color of the mixed paint changes with the change of temperature, so the paint color of the wire clamp and the paint color of the wire guide change due to the rise of the fault temperature of the power transmission line, the color-changing temperature of the wire clamp and the adjacent wire fitting can be determined based on the preset paint chromaticity table which is configured in advance in the set, and the defect level of the wire clamp can be determined according to the difference of the color-changing temperatures. The expression of the relationship between the mixed paint and the temperature is shown in Table 1.
Table 1 correspondence list of mixed paint and temperature relationship
It should be noted that, the heating conditions of the wire clamp and the adjacent wire fitting under the fault are not consistent, so even though the wire clamp and the adjacent wire fitting are coated with the mixed paint, the paint color reaction under the same fault state is different, and therefore, the fault degree can be determined by comparing the corresponding color-changing temperatures of the wire clamp and the adjacent wire fitting, and the defect grade of the power transmission wire clamp is obtained.
Further, step 104, before further includes:
and constructing a preset paint chromaticity table according to the color change relation between the temperature and the mixed paint, wherein the preset paint chromaticity table comprises a temperature change gradient, a wire clamp paint color change gradient and a wire paint color change gradient.
The color change relationship between the temperature and the mixed paint is shown in table 1, and referring to table 2, the temperature of the adjacent wire fitting is not higher than 50 ℃, so the color of the wire paint mainly comprises three colors, light gray, off-white and white, but the wire clamp can show various colors from light to dark under different degrees of faults.
TABLE 2 color of wire clamp coating and color variation of wire coating at different temperatures
Taking the color of the wire coating as a reference, if the color of the wire coating is light gray, presetting a coating chromaticity table as follows:
TABLE 3 preset coating colorimetry table for light gray wire coating color
If the wire coating is off-white in color, then:
TABLE 4 preset paint colorimeter when the wire paint color is off-white
If the wire coating is white in color, then:
TABLE 5 preset paint colorimeter when the wire paint color is white
Based on the three preset paint colorimeter, the comparison of the paint color of the wire clamp and the paint color of the wire clamp can be completed, so that the defect grade of the specific power transmission wire clamp is determined.
It should be noted that, compared with the traditional coating, the electric transmission wire clamp heating automatic color-changing response mixed coating in the embodiment has the advantages that after the conductive part is coated with the coating, when the internal temperature of the electric transmission wire clamp is increased to a specific level, the coating can automatically change color to prompt a user that the current temperature of the conductive part is too high, so that the user is warned to maintain in time. The coating has the characteristics of automatic sensing and automatic color changing, is simple and easy to use, and does not need to additionally add any sensor or element.
