Description

Technical Field

[0001] The invention belongs to the technical field of corrosion inhibition monitoring of electric equipment, and in particular relates to a monitoring system for multi-metal corrosion inhibition of electric equipment by atmospheric environment. Background Art

[0002] With the continuous advancement of my country's economic construction, the power energy industry has ushered in great development. The power system uses a large number of power and electronic equipment, many of which are installed in outdoor environments and repeatedly experience high temperature and high humidity environments, causing aging and corrosion of equipment structures, electronic components, metal conductors and other materials, which can easily lead to frequent equipment failures and shorten the service life of the equipment.

[0003] Due to the complex and compact internal structure of power electronic equipment, various metal components and conductor materials coexist in a limited space. It is difficult for general anti-corrosion measures to achieve good protection effects without affecting the normal use of the equipment.

[0004] Therefore, further improvements are made to the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide a monitoring system for the atmospheric environment's multi-metal corrosion inhibition of power equipment, which performs anti-corrosion treatment and corrosion monitoring on the structure of the power equipment through a corrosion acquisition module, a corrosion analysis module and a vapor phase corrosion inhibition module, thereby ensuring the safe operation of the power equipment, and performs three-dimensional visualization of each structure of each power equipment through a background management module, thereby displaying it more intuitively, and has the advantages of intelligence, ease of use and good economic effect.

[0006] To achieve the above objectives, the present invention provides a monitoring system for atmospheric environment corrosion inhibition of multiple metals in power equipment, which is installed in the power equipment and used to monitor the aging corrosion of the metals in the power equipment, including a corrosion collection module, a corrosion analysis module and a gas phase corrosion inhibition module, wherein:

[0007] Before monitoring, the vapor phase corrosion inhibition module uses a multi-metal vapor phase corrosion inhibitor to fully cover the structure of the power equipment including metal structural parts and electrical components with anti-corrosion spraying, so that the power equipment is in a first state;

[0008] During monitoring, the corrosion collection module collects the corrosion degree of the first state of the power equipment to obtain the initial corrosion value of each structure of the power equipment in the first state and transmits the initial corrosion value to the corrosion analysis module;

[0009] The corrosion analysis module uses the obtained initial corrosion value as the origin value of the actual corrosion curve of the structure of the current power equipment, and the corrosion collection module periodically collects the corrosion degree of each structure of the power equipment according to a preset time interval and periodically transmits the obtained corrosion value to the corrosion analysis module, so that the corrosion analysis module outputs the actual corrosion curve of each structure of the current power equipment according to the obtained corrosion value;

[0010] The corrosion analysis module compares and analyzes the actual corrosion curve of each structure with the historical corrosion curve extracted from the historical library (no anti-corrosion spraying is performed on the power equipment), thereby obtaining the anti-corrosion effect data of each structure after the anti-corrosion spraying of the vapor phase corrosion module, and transmits the anti-corrosion effect data of each structure to the background management module through the wireless transmission module. The background management module displays the anti-corrosion effect data of each structure of each power equipment through three-dimensional visualization;

[0011] The corrosion analysis module compares and analyzes the actual corrosion curve of each structure with the preset corrosion threshold curve to determine whether the actual corrosion degree of each structure has reached the alarm corrosion threshold. If the corrosion threshold is reached, the generated alarm information is transmitted to the background management module through the wireless transmission module, so that the background management module can display the specific location of the structure of the current alarm power equipment through three-dimensional visualization.

[0012] As a further preferred technical solution of the above technical solution, for the actual corrosion curve and the preset corrosion threshold curve:

[0013] When the actual corrosion degree of each structure reaches the first degree of the corrosion threshold (10%-50%, assuming that reaching 100% is reaching the corrosion threshold), the corrosion analysis module transmits the generated first alarm information to the background management module;

[0014] When the actual corrosion degree of each structure reaches the second degree (50%-80%) of the corrosion threshold, the corrosion analysis module transmits the generated second alarm information to the background management module, and the background management module generates a second instruction and transmits it to the wireless transmission module, so that the second instruction is wirelessly transmitted to the vapor phase corrosion inhibition module, and then the vapor phase corrosion inhibition module automatically performs anti-corrosion spraying on the structure that reaches the second degree, and adjusts the actual corrosion curve of the current structure and records the anti-corrosion spraying again in the background management module;

[0015] When any structure of the power equipment reaches the second level again after the number of times of anti-corrosion spraying, the corrosion analysis module will transmit the generated replacement alarm information to the background management module through the wireless transmission module. The background management module will display the structure of the power equipment that needs to be replaced through three-dimensional visualization, and generate replacement arrangement information (arrange maintenance personnel to replace it. If anti-corrosion spraying is performed again at this time, the previous effect has been achieved. From the perspective of economy, safety and development, replacing the specific structure is the preferred choice).

[0016] As a further preferred technical solution of the above technical solution, the multi-metal vapor phase corrosion inhibitor is an imidazole derivative, which is mixed according to a preset mass ratio, and is adsorbed into nano-silica gel powder after being modulated into an aqueous solution, and is obtained after being dried at low temperature.

[0017] As a further preferred technical solution of the above technical solution, the corrosion analysis module also performs multi-metal corrosion inhibition analysis on structures made of different metals of the same power equipment, so as to obtain the corrosion resistance data of each structure under the same atmospheric environment, and transmit the corrosion resistance data to the background management module, so that the background management module can obtain the degree of corrosion resistance enhancement of the multi-metal vapor phase corrosion inhibitor on different metals (thereby reversely adjusting the ratio and manufacturing process of the multi-metal vapor phase corrosion inhibitor or changing the metal parts of the power equipment structure, so as to improve the overall corrosion resistance).

[0018] As a further preferred technical solution of the above technical solution, the vapor phase corrosion inhibition module is provided with a self-checking unit, which periodically detects the remaining amount of the multi-metal vapor phase corrosion inhibitor, thereby transmitting the generated remaining amount information to the background management module through the wireless transmission module. The background management module displays the remaining amount of the multi-metal vapor phase corrosion inhibitor of the vapor phase corrosion inhibition module of each power equipment through three-dimensional visualization, and outputs the multi-metal vapor phase corrosion inhibitor replacement alarm information when the remaining amount reaches the minimum threshold.

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0021] In the preferred embodiments of the present invention, those skilled in the art should note that the power equipment and structures involved in the present invention may be regarded as prior art.

[0022] Preferred embodiments.

[0023] The present invention discloses a monitoring system for atmospheric environment corrosion inhibition of multiple metals in power equipment, which is installed in the power equipment and used to monitor the aging corrosion of the metals in the power equipment, and comprises a corrosion collection module, a corrosion analysis module and a gas phase corrosion inhibition module, wherein:

[0024] Before monitoring, the vapor phase corrosion inhibition module uses a multi-metal vapor phase corrosion inhibitor to fully cover the structure of the power equipment including metal structural parts and electrical components with anti-corrosion spraying, so that the power equipment is in a first state;

[0025] During monitoring, the corrosion collection module collects the corrosion degree of the first state of the power equipment to obtain the initial corrosion value of each structure of the power equipment in the first state and transmits the initial corrosion value to the corrosion analysis module;

[0026] The corrosion analysis module uses the obtained initial corrosion value as the origin value of the actual corrosion curve of the structure of the current power equipment, and the corrosion collection module periodically collects the corrosion degree of each structure of the power equipment according to a preset time interval and periodically transmits the obtained corrosion value to the corrosion analysis module, so that the corrosion analysis module outputs the actual corrosion curve of each structure of the current power equipment according to the obtained corrosion value;

[0027] The corrosion analysis module compares and analyzes the actual corrosion curve of each structure with the historical corrosion curve extracted from the historical library (no anti-corrosion spraying is performed on the power equipment), thereby obtaining the anti-corrosion effect data of each structure after the anti-corrosion spraying of the vapor phase corrosion module, and transmits the anti-corrosion effect data of each structure to the background management module through the wireless transmission module. The background management module displays the anti-corrosion effect data of each structure of each power equipment through three-dimensional visualization;

[0028] The corrosion analysis module compares and analyzes the actual corrosion curve of each structure with the preset corrosion threshold curve to determine whether the actual corrosion degree of each structure has reached the alarm corrosion threshold. If the corrosion threshold is reached, the generated alarm information is transmitted to the background management module through the wireless transmission module, so that the background management module can display the specific location of the structure of the current alarm power equipment through three-dimensional visualization.

[0029] Specifically, for the actual corrosion curve and the preset corrosion threshold curve:

[0030] When the actual corrosion degree of each structure reaches the first degree of the corrosion threshold (10%-50%, assuming that reaching 100% is reaching the corrosion threshold), the corrosion analysis module transmits the generated first alarm information to the background management module;

[0031] When the actual corrosion degree of each structure reaches the second degree (50%-80%) of the corrosion threshold, the corrosion analysis module transmits the generated second alarm information to the background management module, and the background management module generates a second instruction and transmits it to the wireless transmission module, so that the second instruction is wirelessly transmitted to the vapor phase corrosion inhibition module, and then the vapor phase corrosion inhibition module automatically performs anti-corrosion spraying on the structure that reaches the second degree, and adjusts the actual corrosion curve of the current structure and records the anti-corrosion spraying again in the background management module;

[0032] When any structure of the power equipment reaches the second level again after the number of times of anti-corrosion spraying, the corrosion analysis module will transmit the generated replacement alarm information to the background management module through the wireless transmission module. The background management module will display the structure of the power equipment that needs to be replaced through three-dimensional visualization, and generate replacement arrangement information (arrange maintenance personnel to replace it. If anti-corrosion spraying is performed again at this time, the previous effect has been achieved. From the perspective of economy, safety and development, replacing the specific structure is the preferred choice).

[0033] More specifically, the multi-metal vapor phase corrosion inhibitor is an imidazole derivative, which is mixed according to a preset mass ratio, and is adsorbed into nano-silica gel powder after being modulated into an aqueous solution, and is obtained after being dried at low temperature.

[0034] Preferably, the corrosion analysis module also performs multi-metal corrosion inhibition analysis on structures made of different metals of the same power equipment, so as to obtain the corrosion resistance data of each structure under the same atmospheric environment, and transmit the corrosion resistance data to the background management module, so that the background management module can obtain the degree of corrosion resistance enhancement of the multi-metal vapor phase corrosion inhibitor on different metals (thereby reversely adjusting the ratio and manufacturing process of the multi-metal vapor phase corrosion inhibitor or changing the metal parts of the power equipment structure, so as to improve the overall corrosion resistance).

[0035] Preferably, the vapor phase corrosion inhibition module is provided with a self-checking unit, which periodically detects the remaining amount of the multi-metal vapor phase corrosion inhibitor, thereby transmitting the generated remaining amount information to the background management module through the wireless transmission module. The background management module displays the remaining amount of the multi-metal vapor phase corrosion inhibitor of the vapor phase corrosion inhibition module of each power equipment through three-dimensional visualization, and outputs the multi-metal vapor phase corrosion inhibitor replacement alarm information when the remaining amount reaches the minimum threshold.

[0036] Preferably, the multi-metal vapor phase corrosion inhibitor is an imidazole derivative, which can volatilize and adsorb on the metal surface at room temperature and higher temperature. The N atom in the imidazole ring has a large electronegativity, can preferentially contact the metal surface and provide lone pairs of electrons to hybridize the d empty orbitals of common and easily corrosive Fe, Cu, Zn, Ag, Al and other conductive metal element atoms, forming coordination bonds and adsorbing on the metal surface, thereby changing the double electric layer structure of the metal surface and increasing the activation energy of the metal ionization process.

[0037] In addition, the imidazole ring skeleton contains a large number of non-polar C atoms and H atom groups, which are far away from the metal surface and form a dense monomolecular film, isolating the corrosive medium from the metal surface and hindering the transfer of charge and matter. The strong adsorption of N atoms in the vapor phase corrosion inhibitor and the isolation of the CH group in the imidazole ring help slow down the corrosion of the metal.

[0038] The effect is:

[0039] 1. Multi-metal universal vapor phase corrosion inhibitor is mainly made of imidazole derivatives, micro-nano inorganic porous silicon powder and pure water as raw materials, and is prepared by sol-gel method + low-temperature drying. The product has good controlled release, is safe and environmentally friendly, and is easy to use.

[0040] 2. This corrosion inhibitor is a mixed corrosion inhibitor that can simultaneously inhibit the cathode reaction and the anode reaction of the electrochemical corrosion process, thereby slowing down the electrochemical corrosion rate. The EIS test results after hanging the plate show that the corrosion inhibitor increases the charge transfer resistance of the metal surface by volatilizing to the metal surface, thereby increasing the corrosion resistance of the metal.

[0041] 3. The corrosion inhibitor has a corrosion inhibition effect on a variety of metals such as copper, brass, A3 steel, silver, and zinc. The corrosion inhibition efficiency for brass and A3 steel can reach 78.13% and 71.86%. Due to their good self-passivation, the degree of vapor phase corrosion of metal aluminum and zinc is very small, and the corrosion inhibition rate is greater than 10%. The degree of vapor phase corrosion of metal silver is also very slight, which may be related to the low activity of silver itself.

[0042] 4. Adding vapor phase corrosion inhibitors to metal coatings can greatly improve the protective effect of the coatings, thereby extending the service life of the coatings. Doping corrosion inhibitors in the coatings can increase the electron transfer resistance of the electrochemical corrosion process, inhibit the corrosion rate, and extend the service life of the coatings.

[0043] It is worth mentioning that the technical features such as electrical equipment and structures involved in the patent application of this invention should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field and should not be regarded as the inventive point of this patent. This patent will not be further elaborated.

[0044] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
