Oil immersed transformer: a key equipment for modern power transmission

1.Overview of oil immersed transformer

Oil immersed transformer are the most common type of transformer in power systems, widely used in power transmission and distribution. Its working principle is to use oil as a cooling medium to help the transformer maintain a stable working temperature, ensuring the efficiency and safety of power transmission.

1.1 Working principle of oil immersed transformer

The core components of an oil immersed transformer include the iron core, winding, and transformer oil. Oil immersed transformer convert input high voltage into low voltage through electromagnetic induction principle and transmit it to downstream equipment. Transformer oil not only serves as a cooling agent, but also provides insulation protection to prevent electrical faults.

1.2 Advantages of Oil Immersed Transformer

Oil immersed transformer have the following significant advantages:

• Good cooling effect: Transformer oil effectively reduces the temperature during equipment operation and extends the service life of the transformer.
• Low cost: Compared with other types of transformers, oil immersed transformers have lower production and maintenance costs.
• Stable work: Transformer oil remains stable over long-term use, reducing malfunctions caused by temperature fluctuations.
