Oil-immersed transformers are a common type of power transformer, characterized by having the transformer's core and windings submerged in insulating oil

Oil-immersed transformers are a common type of power transformer, characterized by having the transformer's core and windings submerged in insulating oil. This design offers the following key advantages:

1. Superior insulation performance: The insulating oil has excellent dielectric properties, effectively insulating the various transformer components and enhancing the overall insulation strength of the device.

2. Effective heat dissipation: The insulating oil can efficiently absorb the heat generated by the windings and core, improving the transformer's load-carrying capacity.

3. Simple and reliable structure: The oil-immersed design has a straightforward construction, making manufacturing and maintenance relatively easier, and contributing to the transformer's overall reliability.

4. Long service life: The excellent insulation and cooling performance ensure a long operational lifespan for the transformer.

The main components of an oil-immersed transformer include:

• The core: Made of high-quality electrical steel, it forms the magnetic circuit of the transformer.
• The windings: Consisting of conductive coils, divided into high-voltage and low-voltage windings.
• The oil tank: Houses the insulating oil to protect the core and windings.
• Oil release devices: Used to vent any accumulated gases and moisture from the transformer interior.
• Cooling systems: Including oil circulation pipework and radiators, to enhance the transformer's heat dissipation.
• Other accessories: Such as temperature gauges, oil level indicators, and oil analysis equipment, for monitoring the transformer's operational status.

Oil-immersed transformers are widely used in various stages of power systems, including generation, transmission, and distribution. As the demand for electricity continues to grow, the application prospects for oil-immersed transformers remain promising.
