Maintaining dry-type transformers is crucial to ensuring stable operation of power equipment. Here are some practical maintenance tips to help you keep dry-type transformers in good condition:
Regular cleaning: Ensure the dry-type transformer surface, heat sink, and casing are free of dirt and debris and kept clean.
Check temperature: Use an infrared thermometer or other tool to regularly check the temperature and ensure it is within the normal range.
Check insulation: Regularly test insulation resistance, dielectric loss, and other indicators to ensure good insulation performance.
Check windings: Inspect windings for short circuits, open circuits, or localized overheating.
Check connections: Ensure all connections are tight and free of looseness or corrosion.
Check accessories: Ensure accessories such as heat sinks and fans are functioning properly.
Preventive testing: Regularly measure winding resistance and perform insulation tests to prevent potential problems.
Avoid overloading: Avoid prolonged overload operation to ensure overloaded operation.
Regular inspections: Regularly observe operating conditions to identify and address potential problems promptly.
