Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a power transformer capable of accelerating transformer oil circulation. Background Art

[0002] Transformer oil is a mineral oil obtained by distillation and refining of natural petroleum. It is a mixture of pure, stable, low-viscosity, good insulation and cooling liquid natural hydrocarbons obtained by acid-base refining of lubricating oil fractions in petroleum. Commonly known as square shed oil, it is a light yellow transparent liquid; the main functions of transformer oil: insulation: transformer oil has a much higher insulation strength than air. Insulating materials immersed in oil can not only improve insulation strength, but also protect against moisture erosion; heat dissipation: transformer oil has a large specific heat and is often used as a coolant. The heat generated during the operation of the transformer causes the oil near the core and winding to expand and rise due to heat. Through the up and down convection of the oil, the heat is dissipated through the radiator to ensure the normal operation of the transformer.

[0003] However, the existing power transformers that accelerate the circulation of transformer oil often only accelerate the circulation speed of the transformer oil, but fail to eliminate the heat carried by the transformer oil well, resulting in poor heat dissipation effect. Therefore, the present application provides a power transformer that accelerates the circulation of transformer oil to meet the demand. Utility Model Content
