What are the common faults and treatment methods of lightning arresters?

Bar pillar porcelain insulators are mainly used on high-voltage appliances or indoor power distribution devices as insulation and fixed conductors. The specific occasions for which it is suitable include: Outdoor power stations and substations: rod-shaped pillar porcelain insulators can be used in outdoor power stations and substations with power frequency AC voltage of 40.5kV~1100kV, as insulation and support components for power distribution devices and electrical equipment. These insulators are able to withstand high voltages and harsh environmental conditions, ensuring safe and stable power transmission and distribution. UHV transmission project: In UHV transmission projects, such as Longdong-Shandong ± 800 kV UHV DC transmission project and Jindongnan-Nanyang-Jingmen 1000 kV UHV AC test demonstration project, rod-shaped pillar porcelain insulators are widely used to support and insulate high-voltage transmission lines. Dirty environment: Stain-resistant rod pillar porcelain insulators are suitable for medium, heavy and extra-heavy polluted areas. In these environments, insulators need to have good resistance to contamination to prevent flashover accidents caused by contamination. Cold areas: rod pillar porcelain insulators can be used in the ambient temperature range of -40°C~+40°C, and some products can even be used in areas with an altitude of 4000m. Therefore, they are also suitable for power installations in cold regions and high altitudes. Other special occasions: In addition to the above, rod strut porcelain insulators can be customized and modified according to specific needs to suit other special applications. For example, in situations where it is necessary to bear a large mechanical load, an insulator with higher mechanical strength can be selected; In situations where radio interference needs to be reduced, insulators with low radio interference characteristics can be selected. In short, rod strut porcelain insulators are widely used in various fields of power system because of their excellent insulation properties, mechanical strength and environmental resistance. When choosing an insulator, it should be selected according to the specific use environment and requirements, and comprehensively considering the material, performance, price and other factors.
