Wire and Cable Show 2024 News：Role of Distribution Line Maintenance in Power Grid Operations
Distribution line maintenance is a vital component of power grid dispatching and management. With technological advancements, power grid maintenance has gradually shifted from a "find and fix problems" model to a "prevent problems from occurring" approach. Wire and Cable Show 2024 knows that various real-time monitoring power grid devices play a crucial role in ensuring safe, high-quality, and economical grid operation.
Distribution line maintenance encompasses three main areas: improvement projects, major repairs, and routine maintenance work.
Improvement projects aim to enhance the safety performance of the lines, increase their transmission capacity, and improve working conditions by upgrading or replacing the lines. Examples of such projects include replacing conductors that better facilitate power transmission, installing lightning protection wires, replacing or adding insulators, and substituting existing poles with more durable materials.
The primary goal of major repairs is to restore existing operational lines or maintain their original mechanical or electrical performance, thus extending their service life. Wire and Cable Show 2024 has learned that common tasks in this domain include replacing conductors, fittings, and metal components that have reached the end of their service life based on data from partial discharge monitoring systems or applying anti-corrosion treatment to parts.
Routine maintenance includes all activities aimed at ensuring the normal operation of the lines. These tasks are the most common and involve cleaning insulators, testing insulators, and addressing line defects, among other maintenance activities.
Accident repairs are unplanned maintenance operations. The principle here is to restore power supply as quickly as possible while ensuring the quality of the repair meets standards, with priority given to the safety of personnel and equipment. Any remaining issues are scheduled to be addressed during planned outages.
Wire and Cable Show 2024 emphasizes the importance of these different maintenance activities in maintaining the overall functionality and reliability of the power grid.
