Oil-Immersed Transformer Industry knowledge
1. Working principle and importance of oil-immersed transformer
Oil-immersed transformers are vital components in power systems, and their basic working principles involve electromagnetic induction and energy transmission. In power transmission and distribution systems, these transformers are responsible for changing voltage levels to suit the power needs of different parts. Its core principle is based on Faraday's law and Lenz's law. By applying an alternating current in the primary coil, a magnetic field is generated, thereby inducing the voltage in the secondary coil.
The reason why oil-immersed transformers use tanks filled with insulating oil (usually mineral oil or silicone oil) is due to several considerations. This oil has good insulating properties, helps prevent discharges and provides a cooling effect. These characteristics enable the transformer to operate stably for a long time. In addition, the design of the oil tank also helps dissipate heat and keep the internal temperature of the transformer within a controllable range to ensure equipment operation efficiency and safety.
Oil-immersed transformers play an important role in the power grid, mainly by stabilizing and adjusting voltage to ensure the safe operation of the power system. They reduce voltage losses, improve power transmission efficiency, and ensure stable power delivery to end users, including homes, factories, and commercial facilities. Therefore, these transformers have an irreplaceable role in the power system.

2. Design and technological innovation of oil-immersed transformers
The design and technical aspects of oil-immersed transformers have evolved and improved over the years. To cope with growing power demands and technical challenges, manufacturers continue to explore new design and technical solutions.
Recent technological innovations mainly focus on the following aspects:
High temperature superconducting material applications
Using high-temperature superconducting materials as coil materials can reduce the resistance of the coil, thereby reducing energy loss and improving efficiency. The use of this material also helps reduce the size and weight of the transformer.
Intelligent monitoring and diagnostic system
Sensors and monitoring devices are introduced to realize real-time monitoring and remote management of oil-immersed transformers. These systems can collect large amounts of data and use machine learning and artificial intelligence technologies to predict and diagnose faults, help with timely maintenance and management, and improve equipment reliability and safety.
Environmental protection and energy efficiency
The industry is increasingly focusing on environmentally friendly and more energy-efficient designs. Choosing to use biodegradable or silicone oils instead of traditional mineral oils can help reduce environmental impact and improve the energy efficiency of your transformer.
These innovations not only improve the performance and reliability of oil-immersed transformers, but also enable them to better adapt to the needs of future power systems.

3. Industry trends and challenges
The oil-immersed transformer industry is facing a series of new trends and challenges, which will affect the development and application of future transformers.
Renewable energy integration
With the rapid development of renewable energy, power grids need to better adapt to unstable power input patterns and frequencies. Oil-immersed transformers need to be more flexible and responsive to effectively integrate and manage renewable energy.
Supply chain and raw material issues
The transformer manufacturing industry faces the challenge of unstable raw material supply chains. For example, some scarce metals or special insulation materials may be in short supply, which may affect production cycles and costs.
digital transformation
The industry is developing towards digitalization and intelligence. This transformation requires investment in smart manufacturing, data analytics and IoT technologies to improve production efficiency and product quality while meeting growing market demand.
The development and innovation of the oil-immersed transformer industry is to meet the growing power demand and cope with the complexity and challenges of future power systems. Through continuous technological improvements and adaptation to new trends, oil-immersed transformers will continue to play a key role in the field of power transmission and distribution.
