Cooling oil according to the principle of heat generated by the coil and magnetic core during operation will transfer to the oil. The temperature of the oil will spread out to the outside through the transformer's metal shell.
Oil-immersed transformers consist of the magnetic core, windings and bushings. The magnetic core provides a path for magnetic flow. Windings create a magnetic field and consist of a conductor coil, wrapped around the core and insulated with press board barriers and screens. The thickness of the winding insulation increases with voltage. Bushings connect transformer windings to a substation. A characteristic feature of an oil-immersed transformer is the oil conservator. It simplifies operation by monitoring the oil level in a tank and providing space for thermal expansion of the oil.
Moreover, the minimum net distance between the outer profile of the fuel oil-immersed transformer and the wall and door of the transformer room also has strict distance requirements. The various civil structures, fire barriers and storage tanks of oil-immersed power transformer substations are designed because of the flammability and liquidity of oil. In addition, "when the transformer room is located in the building, the door shall be a Class A fire door." In this way, the construction investment designed to prevent fire in each substation is naturally much larger.
