Lantern Festival reunion, polish your eyes, do not become fake wipe tears!
1. The low voltage winding of oil immersed transformer generally adopts the cylindrical structure of copper foil winding, except for the small capacity of copper wire; High voltage winding adopts multi layer cylindrical structure, which makes the distribution of ampere turn of winding balanced, with small magnetic leakage, high mechanical strength and strong short-circuit resistance.
2. The iron core and winding adopt fastening measures respectively. The fastening parts such as the height of the device and the low voltage lead are equipped with self locking locknuts. The structure without lifting the core is adopted, which can withstand the bumping during transportation.
3. The coil and iron core are vacuum dried, and the transformer oil is vacuum filtered and filled to minimize the moisture inside the transformer.
4. The oil tank adopts corrugated sheet, which has breathing function to compensate for the volume change of oil caused by temperature change, so this product has no oil conservator, obviously reducing the height of transformer.
5. Because the corrugated plate replaces the oil conservator, the transformer oil is isolated from the outside, which effectively prevents the entry of oxygen and water and leads to the decline of insulation performance.
6. According to the above five performances, the oil-immersed transformer does not need to change oil during normal operation, which greatly reduces the maintenance cost of the transformer and extends the service life of the transformer.
