A three-phase oil-immersed transformer is a type of electrical transformer that utilizes oil as a cooling and insulating medium. It is designed to transform electrical energy between three-phase alternating current (AC) power systems, typically found in industrial and utility applications. These transformers are constructed with multiple windings and a core made of laminated steel to efficiently step up or step down voltage levels while maintaining stable electrical characteristics. The oil within the transformer not only serves to cool the unit but also provides insulation between windings and the transformer's core, ensuring safe and reliable operation.
Good cooling performance: Oil immersed transformers use oil as a cooling medium, which can effectively dissipate heat, maintain a reasonable temperature during transformer operation, and ensure long-term stable operation of the equipment.
Good insulation performance: The oil in oil immersed transformers has excellent insulation performance, which can effectively isolate the electrical components inside the transformer, reduce the risk of breakdown and leakage, and improve the safety and reliability of the equipment.
Lower operating noise: Oil immersed transformers have lower noise during operation, which is very important for applications that require low-noise environments, such as residential areas or office spaces.
Strong adaptability: Oil immersed transformers are suitable for various environmental conditions, such as high-altitude areas, humid environments, and heavily polluted areas, and can operate stably and reliably.
Long lifespan and maintainability: With proper maintenance and upkeep, oil immersed transformers can have a longer service life and are relatively easy to maintain, making regular inspections and repairs convenient.
High efficiency and economy: Oil immersed transformers usually have high efficiency and can effectively reduce energy losses, thereby saving energy costs in long-term operation.
