Oil Cooled Power Transformer Performance Characteristics

a. The low-voltage windings of oil cooled power transformer generally adopt a cylindrical structure with copper foil winding except for small-capacity copper wires; the high-voltage windings adopt a multi-layer cylindrical structure to balance the ampere-turn distribution of the winding and prevent magnetic flux leakage Small, high mechanical strength, strong short circuit resistance.

b. The oil cooled power transformer iron core and the winding have adopted fastening measures respectively. The fastening parts such as the height of the device and the low-voltage lead wire are all equipped with self-locking locknuts. The non-hanging core structure is adopted, which can withstand the shock of transportation.

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

d. The oil tank adopts corrugated sheet, which has a breathing function to compensate the volume change of oil caused by temperature changes, so this product does not have an oil storage tank, which obviously reduces the height of the oil cooled power transformer.

e. Since the corrugated sheet replaces the oil conservator, the transformer oil is isolated from the outside world, which effectively prevents the entry of oxygen and water and causes the decline of insulation performance.

f. According to the above five points of performance, it is guaranteed that the oil cooled power transformer does not need to change oil during normal operation, which greatly reduces the maintenance cost of the transformer and prolongs the service life of the transformer.
