Oil-immersed transformers are transformers that use insulating oil as a cooling and insulating medium. Its basic working principle is to convert AC power of one voltage level into AC power of another voltage level of the same frequency through electromagnetic induction. The core components of oil-immersed transformers include iron core, coils and insulation materials, which are usually installed in a welded steel tank filled with insulating oil.
What are the main application areas of oil-immersed transformers?
1. Power industry
In the power industry, oil-immersed transformers are one of the important components of the power grid, and their application areas are wide and core.
Power plant: Oil-immersed transformers play the role of boosting in power plants. The oil-immersed transformer boosts the electric energy generated by the generator and transmits it to the power grid. This step is crucial for the long-distance transmission of electric energy, because boosting can reduce line losses and improve transmission efficiency.
Power grid system: In the power grid, oil-immersed transformers are used to reduce the voltage of high-voltage electric energy and supply it to users. This conversion process ensures a safe and stable supply of electric energy and meets the electricity needs of different users.
Power transmission and distribution system: Oil-immersed transformers are also used for power distribution in power transmission and distribution systems, distributing electric energy to various power-consuming equipment. In addition, non-partial discharge oil-immersed test transformers can be used to perform partial discharge and power frequency withstand voltage tests on transformers in substations and power transmission and distribution systems to ensure the stability and safety of the power system.
2. Industrial use
Power supply for industrial equipment: The industrial field usually requires the use of electric energy at different voltage levels to meet the needs of different equipment. Oil-immersed transformers can provide stable and reliable voltage conversion to ensure the normal operation of industrial equipment. Many industrial facilities and enterprises use oil-immersed transformers to supply the power required by their internal equipment and machines.
Special environment application: The tank of the oil-immersed transformer is filled with insulating oil, which enables it to work in polluted or humid environments. Therefore, in some special environmental conditions, such as chemical plants, mines, etc., oil-immersed transformers are widely used.
3. Urban power distribution
Urban power distribution network: The urban power distribution system usually operates with a specific voltage (such as 35KV) as the reference voltage. Oil-immersed transformers play a key role in the urban power distribution network. They convert high-voltage electricity into low-voltage electricity suitable for residential, commercial and office areas.
Future development and trends
With the advancement of science and technology and the improvement of environmental awareness, oil-immersed transformers are also constantly improving and innovating. In the future, oil-immersed transformers will develop in a more efficient, environmentally friendly and intelligent direction.
High efficiency and energy saving: Use new insulation materials and advanced electromagnetic design to improve energy conversion efficiency and reduce energy waste.
Environmentally friendly transformer oil: Develop environmentally friendly transformer oil to reduce environmental pollution and protect the ecological environment.
Intelligent monitoring system: Introduce intelligent monitoring system to achieve remote monitoring and fault warning, and improve the safety and reliability of equipment.
