Oil immersed transformer accessories

Transformer accessories can ensure the safe, stable, and efficient operation of transformers, and extend their service life. Oil immersed transformer accessories play an important role in power systems due to their excellent comprehensive performance. Their core advantages are mainly reflected in the following aspects: firstly, using insulating oil as the cooling and insulation medium not only has excellent insulation strength (breakdown voltage ≥ 30kV/2.5mm), but also achieves efficient heat dissipation, with heat dissipation capacity increased by more than 30% compared to dry-type transformers. At the same time, their high temperature resistance characteristics make them capable of withstanding working temperatures of 105 ℃, especially suitable for high load or short-term overload operation. Secondly, its sealed fuel tank design provides IP55 protection level, which can effectively prevent moisture and dirt, adapt to various harsh environments, and with oil buffer design, can reduce winding vibration and extend equipment service life to more than 25 years. Thirdly, equipped with a comprehensive multi protection system, including gas relays for real-time monitoring of internal faults, pressure relief valves to prevent explosions, and intelligent temperature control systems, to ensure safe and reliable operation. In addition, modular design makes maintenance more convenient, and the insulating oil can be filtered and regenerated for use, significantly reducing maintenance costs. Compared to dry-type transformers, oil immersed transformers have significant advantages in heat dissipation efficiency, overload capacity, environmental adaptability, and are particularly suitable for high reliability applications such as industrial power systems, renewable energy power stations, data centers, and rail transit. They have become the preferred solution for medium and high voltage power systems and harsh environments.
