Oil-Immersed Transformer: the key to power transmission and distribution

As one of the most important equipment in the power system, Oil-Immersed Transformer undertakes the important tasks of regulating voltage, transmitting and distributing electric energy. Its working principle is to achieve voltage conversion through electromagnetic induction, which involves magnetic field changes, coil design and the role of insulating oil.

The basic principle of oil-immersed transformer is based on electromagnetic induction. When an input voltage is applied to the primary coil, the resulting changing magnetic field passes through the core and induces a voltage in the auxiliary coil. This changing magnetic field causes an induced electromotive force in the auxiliary coil, thereby transmitting electrical energy from the input end to the output end, realizing voltage conversion.

The coil design of oil-immersed transformers is crucial for voltage conversion. The ratio of the turns of the main and auxiliary coils determines the conversion relationship between the input and output voltages. By rationally designing the turn ratio of the coil, different voltage conversion ratios can be achieved to meet the needs of different occasions. In addition, the coil winding process and material selection also play an important role in the performance of the transformer.

The iron core in an oil-immersed transformer plays a role in concentrating the magnetic field and reducing energy loss. The iron core is usually made of laminated silicon steel sheets with high magnetic permeability and low hysteresis characteristics, which can effectively guide the magnetic field and reduce its own energy loss, thus improving the efficiency and stability of the transformer.

Insulating oil is an indispensable component of oil-immersed transformers. It is used to insulate the coil and iron core to prevent breakdown between them, and also plays a cooling role. When the transformer is working, the insulating oil can effectively absorb and conduct the heat generated, maintaining the stable operating temperature of the transformer, thereby extending the service life of the equipment.

Oil-Immersed Transformers realize the transmission and distribution of electrical energy through electromagnetic induction, coil design, the role of the iron core, and the importance of insulating oil. Its role in the power system is irreplaceable, providing stable and reliable power supply for various applications and laying a solid foundation for the development of future power systems.
