Power transformers are very important devices in power systems, and they require regular maintenance to ensure their safe and reliable operation. Following are some common steps for power transformer maintenance:
Cleaning: Regularly clean the sundries and dirt on the surface of the transformer and the surrounding environment to maintain the ventilation and heat dissipation performance of the transformer, and also help to check the insulation condition around the transformer.
Check the liquid level: Regularly check the liquid level and quality of the transformer oil to ensure that the oil quality is qualified, and at the same time ensure that the oil liquid level is within the specified range to ensure the normal operation of the transformer.
Check the insulation: Regularly check the insulation condition of the transformer, including insulation materials, coils and insulation joints, etc., to ensure that the insulation performance meets the requirements.
Measuring electrical parameters: Regularly measure the electrical parameters of the transformer, including voltage, current, power factor, etc., to ensure that the performance of the transformer meets the requirements.
Check connections: Regularly check the transformer connections, including cables, wiring, and connectors, to make sure they are not loose or corroded, and make sure they are making good contact.
Check accessories: Regularly check the accessories of the transformer, including protective devices, thermometers and pressure gauges, etc., to ensure that they are working properly.
Check mechanical parts: Regularly check the mechanical parts of the transformer, including oil pumps, fans, coolers, etc., to make sure they are working properly.
Check the environment: Regularly check the environment around the transformer, including climate, temperature and humidity, to ensure that the environment will not adversely affect the operation of the transformer.
Maintenance of power transformers requires professional technology and tools, and relevant standards and regulations must be strictly followed during the maintenance process. If any problems or abnormalities are found, measures should be taken to repair or replace them in time to ensure the safety and reliability of the transformer.
