The phase Oil immersion transformer adopts a filled sealed corrugated oil tank shell, which is a permanently sealed oil tank with its elasticity to adapt to oil expansion. Oil immersed transformer has been widely used in various power distribution equipment.

Compared with the ordinary oil-immersed transformer, the fully sealed transformer eliminates the oil conservator. The corrugated sheet in the corrugated tank is elastic and can automatically adjust and compensate for changes in the amount of oil. The transformer is isolated from the air to prevent and slow down oil deterioration and insulation aging, enhance the operation reliability, and is maintenance-free during normal operation.

The transformer core is stacked with high-quality cold-rolled silicon steel sheets, which effectively reduces no-load loss and no-load current. At the same time, through the binding process of the iron core, the tightness of the iron core is ensured, and the noise level is reduced during operation.

The transformer is mainly composed of an iron core, winding, oil tank, insulating sleeve, tap changer, etc.

a. Low voltage winding of oil-immersed transformer adopts a cylindrical structure; High voltage winding adopts multi-layer cylindrical structure to balance the ampere turn distribution of the winding, with small magnetic leakage, high mechanical strength, and strong short-circuit resistance.

b. The iron core and winding adopt fastening measures, respectively, and the fastening parts, such as the height and low-voltage lead, are equipped with locknuts, which can withstand the shock of transportation.

c. The coil and iron core are vacuum dried, and the transformer oil is vacuum filtered and injected to minimize the moisture inside the transformer.

d. The tank design uses a corrugated sheet with respiratory function, which can effectively compensate the oil volume change caused by the temperature change.Therefore, the product has no oil conservator, obviously reducing the height of the transformer.

e. By using corrugated sheets instead of traditional oil storage tanks, the transformer oil is completely isolated from the outside world, which effectively avoids the intrusion of oxygen and water, and protects the insulation performance of the transformer from being reduced.
