Description

Technical Field

[0001] The invention relates to an insulator surface cleaning technology, in particular to an algae cleaning agent and a cleaning method for an algae-covered insulator surface. Background Art

[0002] Insulators are one of the most important components in the power system, mainly serving as electrical isolation and mechanical support. The cleanliness of the insulator surface directly affects the insulation performance and thus the stability of the power system. Algae growth and reproduction require appropriate temperature and humidity, and the southwest region of my country happens to have the natural conditions for algae growth. Therefore, insulators in power transmission and transformation equipment in the southwest region of my country are prone to algae growth. Algae growth on the surface of power transmission and transformation insulators may affect the electrical performance, hydrophobicity and physical and chemical properties of the insulators. On the one hand, the algae growth attached to the surface of the insulator will make the surface of the insulator more prone to dirt accumulation, thereby increasing the probability of flashover accidents. On the other hand, the algae on the surface of the insulator are easily damaged under the action of external forces, resulting in an increased risk of hand or foot slip accidents during operation and maintenance, which greatly affects the safety and efficiency of maintenance work. At present, traditional cleaning methods mostly use high-pressure water guns or manual wiping, which is not only inefficient, but also damages the surface of the insulator in some cases, affecting its service life. Therefore, it is urgent to study a special cleaning method for algae on the surface of algae-covered insulators for targeted treatment.

[0003] Mechanical cleaning is currently one of the common methods for cleaning algae on the surface of algae-covered insulators. Mechanical cleaning is a traditional cleaning method. For algae with a shorter growth time, its adhesion is smaller, and it is generally wiped off with a rag. For algae with a longer growth time, due to its greater adhesion, it cannot be removed with a rag, so brushes, scrapers and other tools are often used for manual cleaning. This method not only has a mediocre cleaning effect, but also has many disadvantages. For example, scraping with a blade can easily scratch the surface of the insulator, leaving scratches on its surface, resulting in a decrease in its anti-pollution flashover performance, thereby shortening the service life of the insulator. In addition, since some algae have greater adhesion, it takes a lot of time to clean.

[0004] Chemical cleaning agents are used to remove algae contamination based on traditional mechanical cleaning. Chemical cleaning agents are used to "dissolve" the algae on the surface of the insulators, and then wipe them off with a rag. In recent years, a variety of special cleaning agents have been developed to remove algae, moss and other microorganisms on the surface of power transmission and transformation equipment. They have a good effect on cleaning surface moss, but there are currently no standards for the performance indicators of various cleaning agents. It is unknown whether the cleaning agents meet the physical, chemical and electrical properties, and it is also unknown whether they will cause corrosion and other damage to the insulators themselves after cleaning.

[0005] High-pressure water gun cleaning is also one of the commonly used cleaning methods. High-pressure water gun cleaning is to use high-pressure water flow to wash the surface of the insulator to remove the algae on the surface. Using this method to clean the algae on the surface of the insulator not only requires a lot of labor costs and time costs, but is also affected by environmental factors such as weather and temperature, as well as the constraints of the construction operation environment. On the other hand, for algae that have grown for a long time, due to their strong adhesion, the effect of using high-pressure water gun cleaning is not satisfactory.

[0006] It should be noted that the information disclosed in the above background technology section is only used for understanding the background of the present application, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0075]

[0076] Cleaning process:

[0077] ① Surface pretreatment: Pre-spray the surface of the algae-covered insulator, and use a low-pressure sprayer to evenly spray the special cleaning agent.

[0078] ②Standing reaction: Wait for the cleaning agent to fully react with the algae and let it stand for 5-10 minutes to ensure that the biological enzyme decomposes the algae cell wall.

[0079] ③ Flushing: Use low-pressure clean water to rinse the surface of the insulator to ensure that algae and cleaning agent residues are completely removed.

[0080] ④Surface drying: Use an air flow dryer to dry the surface of the insulator to prevent secondary contamination caused by residual moisture.

[0081] Experimentation and performance testing

[0082] The algae cleaning agent of the present invention is a colorless liquid. After the algae cleaning agent evaporates, no obvious residue remains on the surface of the insulator. It has a slight solvent smell. The original liquid is tested according to the provisions of Q / SH 1020, and the pH value ranges from 6 to 8. The composition of the algae cleaning agent does not contain any substance harmful to the human body and the environment, and does not contain any ozone depleting substance.

[0083] After experimental testing, it was found that the algae cleaning agent of the present invention has a good cleaning effect on algae on the external insulation surface of power equipment. The algae cleaning agent of the corresponding embodiment was used to clean glass insulators, porcelain insulators and silicone rubber composite insulators with algae vegetation, and the algae cleaning rate reached more than 80%.

[0084] In addition, after testing, the algae cleaning agent of the present invention has a flash point greater than 80°C; a ignition point greater than 100°C; a power frequency breakdown voltage greater than 30kV; and a volume resistivity of not less than 1×1010Ω·cm.

[0086] 1) Thorough cleaning: Cleaning agents can effectively remove algae, dirt and other contaminants on the surface of insulators, making the insulators clean again.

[0087] 2) Long-lasting anti-algae effect: The antimicrobial additive adheres to the surface of the insulator during the cleaning process, forming a protective film. This film can continuously release antimicrobial ingredients, inhibit the regeneration of algae and other microorganisms, thereby extending the cleaning cycle of the insulator.

[0088] 3) Reduced cleaning frequency: Due to the long-lasting effect of the additives, the insulator surface can remain clean for a longer period of time, reducing the need for frequent cleaning and lowering maintenance costs.

[0089] 4) Prevent surface corrosion: The growth of algae and microorganisms may cause aging and corrosion of the surface materials of insulators. Antimicrobial additives can effectively inhibit this process and extend the service life of insulators.

[0090] 5) Improve insulation performance: Keeping the surface of the insulator clean and free of algae helps maintain its excellent insulation performance and prevent insulation failure or power failure caused by surface contamination.

[0091] 6) Reduce chemical pollution: Compared with traditional high-frequency cleaning, the application of antimicrobial additives can reduce the amount of cleaning agents used, thereby reducing chemical pollution and impact on the environment.

[0092] 7) High safety: The antimicrobial additives used in the special cleaning method have undergone environmental and safety assessments and are harmless to operators and the environment.

[0093] 8) Reduce maintenance costs: Due to the long-term anti-algae effect after cleaning, maintenance costs are significantly reduced. There is no need to frequently clean and replace insulators, saving manpower and material costs.

[0094] 9) Reduce equipment wear and tear: Longer cleaning cycles and better protection measures help reduce equipment wear and tear caused by frequent cleaning, thereby reducing long-term operating costs.

[0095] In summary, the method proposed in the present invention has significant advantages in efficiently removing algae, inhibiting algae regeneration, extending the service life of insulators, saving maintenance costs, and improving the safety and economy of insulator operation.
