How to extend the life of the transformer ?
One
Preventive maintenance and planned maintenance:
Preventive maintenance: Preventive maintenance is the regular inspection, maintenance and replacement of key parts of the equipment during the operation of the equipment to reduce the failure rate of the equipment. By performing preventive maintenance, the failure rate of transformers can be reduced and the reliability of equipment can be improved.
Planned maintenance: Planned maintenance is to formulate a periodic maintenance plan based on the service life, fault characteristics and operating environment of the equipment. Planned maintenance can prevent performance degradation caused by long-term operation of equipment, thereby ensuring safe operation of equipment.

The key link of maintenance and repair:
1. Transformer oil: Transformer oil not only has the function of insulation, but also dissipates heat. Therefore, it is very important to regularly check the oil level, oil quality and oil temperature of the transformer oil. If the oil level is insufficient, it needs to be replenished in time; if the oil quality is unqualified, it needs to be processed or replaced.
2. Insulation system: The insulation system of the transformer includes oil-paper insulation and porcelain bottle insulation. Regularly check the aging degree and damage of the insulation system, and carry out treatment or replacement.
3. Coil and core: The coil and core are the core components of the transformer. Regularly check the short circuit and burning condition of the coil, the magnetic flux leakage of the iron core, the temperature rise of hot spots, etc., and deal with or replace them.
4. Power distribution equipment and protection system: Regularly check the connection and contact of power distribution equipment, and whether the fault indication and overload relay of the protection system are working normally.
5. Ventilation and heat dissipation system: Regularly check whether the radiator, fan and other heat dissipation equipment of the transformer are working normally, keep the vents unblocked, and clean the dust and dirt on the surface of the radiator in time. For forced air-cooled transformers, it is necessary to regularly check the operating status of the fan, bearing lubrication, etc.
6. External environment: Regularly check the environment around the transformer, such as weeds, sundries, etc., and keep a certain safe distance to avoid fire and other safety hazards.
7. Test and monitoring: Conduct regular electrical tests and online monitoring of the transformer to understand the operating status of the equipment. Through data analysis, potential faults and potential safety hazards can be discovered in time to provide a basis for equipment maintenance.
