A three-phase oil-immersed transformer is a special type of transformer whose core components – the coil and iron core – are completely immersed in transformer oil.
Characteristics of three-phase oil-immersed transformers
- High efficiency: The three-phase oil-immersed transformer has a high cooling efficiency, effectively reducing the temperature of the coil and iron core, thereby reducing energy loss and improving operational efficiency.
- Stability: Due to the good thermal conductivity of transformer oil, three-phase oil-immersed transformers can maintain stable operation under high temperatures or high load conditions.
- Reliability: The oil-immersed design reduces contact with air, reduces the risk of equipment oxidation and corrosion, and improves the service life of the equipment.
Application fields of three-phase oil-immersed transformers
- Power transmission and distribution system: In the power system, three-phase oil-immersed transformers are mainly used to transmit the high-voltage electricity generated by power plants to the low-voltage power grid in urban and industrial areas. Its efficient energy conversion and stable performance ensure the reliable power supply of the power system.
- Industrial sector: In industrial sectors such as metallurgy, petrochemicals, mining, etc., three-phase oil-embedded transformers can output electrical energy and meet the working needs of various equipment and machinery. They play an important role in electric arc furnaces, electrolytic tanks, oil extraction, and mining equipment.
- High-power load scenarios: Three-phase oil-immersed transformers are widely used in high-power load scenarios such as power grids and industrial and mining enterprises.
How do we maintain and upkeep three-phase oil-immersed transformers?
- Appearance inspection: Regularly inspect the appearance of the transformer, including the color, oil level, porcelain bottle, terminals, etc., of the transformer oil to ensure that there are no abnormal situations.
- Cleaning: Regularly clean the transformer, remove dust and debris from the surface, and keep its appearance clean.
- Oil level inspection: Check the oil level of the transformer to ensure that the oil level is normal. If the oil level is too low, transformer oil should be replenished promptly. If the oil level is too high, check for leaks.
- Temperature inspection: Regularly check the temperature of the transformer to ensure that its operating temperature does not exceed the specified range. The cooling system should be checked for proper operation if the temperature is too high.
- Sound inspection: Regularly check the sound of the transformer. If any abnormal sounds are found, such as buzzing or creaking, they should be checked and dealt with promptly.
- Grounding inspection: Ensure good grounding of the transformer and regularly check whether the grounding resistance meets the requirements.
- Preventive tests: Conduct preventive tests according to regulations, such as insulation resistance tests, voltage withstand tests, etc., to ensure the normal electrical performance of the transformer.
- Replace seals: Regularly replace seals on transformers, such as sealing rings, gaskets, etc., to ensure good sealing and prevent transformer oil leakage.
