Description

Technical Field

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

[0002] When the transformer is running, the temperature will rise and the transformer oil will expand as the temperature rises. The oil pillow plays the role of storing oil. When the temperature drops, the oil level drops and the oil can be replenished into the oil tank to ensure that the oil tank is full of oil and that the iron core and winding are completely immersed in the oil tank, thereby ensuring the insulation strength and heat dissipation of the transformer.

[0003] After the transformer oil enters the oil pillow, the bellows body is squeezed and the air is discharged through the breather. After the transformer oil enters the oil-immersed transformer, the air enters the bellows body through the breather, thereby achieving the breathing effect. However, during use, the bellows body expands and contracts inside the oil pillow. Due to the lack of a limiting structure, the bellows body contacts the inner wall of the oil pillow, increasing the resistance to expansion and contraction, thereby reducing the circulation speed of the transformer oil.

[0004] To this end, we propose a power transformer that can accelerate transformer oil circulation. Utility Model Content
