Oil-immersed transformers are typically installed in a separate transformer room. What are the key points for the installation of oil-immersed transformers? Jiangsu Jula editor takes you through the details.
Oil-filled transformers rely on oil as a cooling medium, including oil-immersed self-cooling, oil-immersed air cooling, oil-immersed cooling, and forced oil circulation. The main transformer at a substation is typically oil-filled, with a voltage ratio of 20KV/500KV or 20KV/220KV. Generally, auxiliary transformers are used to drive power plants with their own loads (such as coal mills, induced draft fans, blowers, circulating water pumps, etc.) and are also oil-filled transformers with a voltage ratio of 20KV/6KV.
The oil-immersed transformer features a fully-oiled and sealed design. The corrugated oil tank shell is a sealed tank that adjusts to oil expansion with its own elasticity. The oil-immersed transformer has been widely used in various power distribution equipment.
