Technical Field

[0001] The utility model belongs to the technical field of transformer equipment, and particularly relates to an oil tank bottom of a transformer. Background Art

[0002] A transformer is a device that uses Faraday's law of electromagnetic induction to step up or down voltage. It typically contains two or more coils and is primarily used to step up or down the voltage of alternating current (AC), change impedance, and separate circuits. Widely used in power plants, it is an essential piece of equipment in production and everyday life. Transformers are classified into gas-filled, oil-immersed, and dry-type test transformers. The body (windings and core) of an oil-immersed transformer is housed in a tank filled with transformer oil. The tank serves to house the transformer, fill it with oil, and dissipate heat and cool it. The tank typically consists of a bottom, sidewalls, a rim, and a lid. The bottom is typically a flat plate with the sidewalls welded to it. The body mounting plate is directly welded to the sidewalls. After welding, the transformer body is placed in the tank and the lid snaps onto the rim.
