What are the anti-corrosion measures for rod pillar porcelain insulators?

The anti-corrosion measures of rod pillar porcelain insulators mainly include the following:

1. Surface protection treatment
Clean up salt spray deposits regularly:
In a salt spray environment, the surface of the insulator is prone to the accumulation of salt spray deposits, which can react with the surface of the insulator and lead to corrosion. Therefore, it is necessary to manually clean the surface of the insulator regularly to avoid the occurrence of corrosion.
Apply the protective layer:
Protective layers such as silicon and ozokerite can be applied on the surface of the insulator to increase the insulation and corrosion resistance of the insulator. These layers form a barrier that prevents the corrosive medium from coming into direct contact with the insulator surface.
Replacement Insulator Type:
Traditional porcelain insulators may not perform well in certain corrosive environments. Therefore, new types of insulators such as silicone insulators, which are stain-resistant and corrosion-resistant, can be considered.
2. Anti-corrosion treatment of iron parts
Paint application:
For the ferrous parts in the transmission and distribution line, such as connectors, supports, etc., paint can be applied to their surface to form a protective layer to prevent corrosion. The iron parts of the newly erected transmission and distribution lines should be painted once after 2-3 years of operation, and then derusted and painted every two years thereafter.
Hot-dip galvanizing:
Hot-dip galvanizing is an effective anti-corrosion method that forms a dense zinc layer on the surface of ferrous parts, thus preventing the corrosive medium from coming into direct contact with ferrous parts. This method is particularly suitable for ferrous components in outdoor and wet environments.
3. Structural design and material selection
Optimized design structure:
By optimizing the design structure, the risk of corrosion of insulators and ferrous components can be reduced. For example, the shape and size of insulators can be optimized to reduce surface area and areas of stagnant water; The connection and layout of ferrous components can be optimized to reduce stress concentrations and build-up of corrosive media.
Choosing corrosion-resistant materials:
When choosing materials for insulators and ferrous components, priority should be given to their corrosion resistance. For example, materials such as ceramic, stainless or alloy steel, which have higher corrosion resistance, can be selected to manufacture insulators and ferrous components.
4. Operation, maintenance and monitoring
Periodic Inspection and Maintenance:
Regular inspection and maintenance of insulators and ferrous components is an important measure to prevent corrosion. A detailed inspection plan and maintenance plan can be formulated, and the surface condition of the insulator and the fastening of the connector can be checked regularly, and the problems found can be dealt with in a timely manner.
On-line monitoring technology:
Real-time monitoring of corrosion of insulators and ferrous components is carried out using online monitoring technology. For example, corrosion monitoring sensors can be installed to monitor the rate and degree of corrosion of insulators and ferrous components so that protective measures can be taken in a timely manner.
In summary, the anti-corrosion measures of rod pillar porcelain insulators include surface protection treatment, anti-corrosion treatment of iron parts, structural design and material selection, as well as operation maintenance and monitoring. These measures can complement and cooperate with each other to jointly improve the corrosion resistance and service life of insulators.
