ABB三相變壓器（English）

ABB is a well-known global leader in the electrical engineering industry, specializing in a wide range of products, including three-phase transformers. ABB's three-phase transformers are designed to meet the demanding requirements of various power distribution and transmission applications. These transformers feature advanced technology and robust construction, ensuring efficient and reliable performance for power systems. ABB's three-phase transformers typically consist of three independent windings configured to produce or receive three sinusoidal voltages with a 120-degree phase difference between each winding. They can be found in different voltage ratings, from low-voltage (LV) for local distribution to high-voltage (HV) and extra-high-voltage (EHV) for long-distance transmission lines. The design incorporates features like oil-immersed or dry type coolers, forced-air cooling, or vacuum-insulated Bushing (VIB) for enhanced insulation and environmental adaptability. ABB also offers a variety of transformer configurations such as autotransformers, instrument transformers, and harmonic filters to cater to specific customer needs. Their transformers are equipped with state-of-the-art protection systems and monitoring capabilities through digital control and automation technologies, enabling remote supervision and optimization of the transformer's operation. In summary, ABB's three-phase transformers represent a premium solution for electric utilities, industries, and other sectors requiring dependable, efficient, and advanced power system components. By combining robust engineering expertise with cutting-edge technologies, ABB ensures that their transformers contribute to a more sustainable and resilient energy infrastructure.
