Power transformers are one of the essential equipment in the power system, known for their reliability, efficiency, and safety. Under normal circumstances, the service life of power transformers can usually reach 20-30 years, but this does not mean that the transformer will not malfunction or fail. Therefore, regular maintenance and repair of power transformers is crucial, which can extend their service life, improve their performance and reliability, and achieve higher operational efficiency. Hengfengyou Electric summarized several aspects of power transformer maintenance:
Cleaning: Cleaning the inside and outside of transformers is very important, especially in areas with harsh environments or production lines of industrial enterprises. External cleaning requires regular wiping and cleaning of dirt, dust, and dirt. Internal cleaning requires the removal of oxides, oil, and corrosive substances from the surface of components.
Maintenance: Repairing transformers can detect potential problems as soon as possible and take timely measures to repair them. Maintenance includes observing and inspecting transformer components, maintaining pressure relief valves and lightning arresters, replacing damaged contacts and switch components, and promptly replacing worn or cracked parts.
Oil quality management: Oil quality is one of the important factors in transformer operation. Regular replacement of transformer oil, timely detection of changes in oil quality, and maintenance of oil quality to meet specified standards can provide good guarantee for the smooth operation of transformers.
Environmental temperature management: Controlling the surrounding temperature is crucial for transformers. Higher ambient temperatures can shorten the lifespan of transformer electrical components and windings, and measures need to be taken to reduce temperature, including installing heat sinks and air cooling equipment.
Protection: Transformers can sometimes be accidentally damaged, such as lightning strikes and overvoltage. By using appropriate lightning arresters, fuses, fast circuit breakers, and surge suppressors, transformers can be effectively protected.
Insulation measurement: The normal operation of transformers requires good insulation performance. By conducting regular insulation measurements, potential problems can be detected and repaired in a timely manner before any faults occur in the insulation system.
Maintaining power transformers can extend their service life, improve their performance and reliability, and achieve higher operational efficiency. Therefore, with proper maintenance and upkeep, the service life of power transformers can be extended to a greater extent, while improving the operational efficiency and safety of the power system. Hengfengyou Electric's power transformer products have sold well in countries and regions such as Central Asia, South Asia, West Asia, Southeast Asia, the Middle East, and the Americas.
