Description

Technical Field

[0001] The present invention relates to the technical field of coating protection performance testing, and in particular to a testing device and method for the aging resistance performance of anti-corrosion coatings of power transmission and transformation equipment. Background Art

[0002] Developing clean energy is an important measure to promote the construction of new power systems and achieve environmental protection. It is worth noting that the desert areas often have strong winds and sand, high temperature differences, strong sunshine, and even saline-alkali land, which poses a severe test to the environmental adaptability of power transmission and transformation equipment.

[0003] In order to improve the anti-corrosion reliability of power transmission and transformation equipment and ensure the safe and stable operation of the power network, the shells and components of power transmission and transformation equipment are usually treated with coating protection. Surveys show that among the current power transmission and transformation equipment, transformers, reactors, GIS, substation cabinets and other equipment mostly use solvent-based organic coatings, such as epoxy zinc-rich primer, epoxy micaceous iron intermediate paint, acrylic polyurethane topcoat, etc. for protection. The protective performance of the coating is directly related to the safe and reliable operation of power transmission and transformation equipment. Therefore, it is of great significance to accurately and effectively simulate the actual service environment of power transmission and transformation equipment and study the corrosion failure behavior of the coating to clarify the anti-corrosion life of the coating, determine the equipment maintenance cycle, and ensure the safe operation of the power system.

[0004] At present, salt spray tests and ultraviolet aging tests are usually used to evaluate the protective performance of coatings. The test equipment lacks wind and sand and electromagnetic field simulation components, and is not suitable for studying the corrosion failure mechanism of coatings in the desert service environment. For the protective coatings of power transmission and transformation equipment in desert areas rich in clean energy, in addition to being affected by temperature and humidity, magnetic fields, and sunlight radiation, they are usually inevitably affected by wind and sand. Therefore, a single environmental aging test is difficult to truly reflect the service conditions of coating materials. It is of great practical significance to carry out corrosion mechanism research on coating samples under the coupling of multiple factors. Summary of the invention
