Performance characteristics of oil immersed transformers:
a. The low-voltage winding of the oil immersed transformer generally adopts a cylindrical structure with copper foil winding except for the small-capacity copper wire; the high-voltage winding adopts a multi-layer cylindrical structure, so that the ampere-turn distribution of the winding is balanced and magnetic leakage Small, high mechanical strength, strong resistance to short circuit.
b. Fastening measures are adopted for the iron core and winding respectively. The fastening parts such as the height of the device and the low-voltage lead wires are equipped with self-locking anti-loosening nuts.
c. The coil and iron core are dried in vacuum, and the transformer oil adopts the process of vacuum oil filtering and oil injection to minimize the moisture inside the transformer.
d. The oil tank adopts corrugated sheet, which has a breathing function to compensate for the volume change of the oil caused by the temperature change, so this product does not have an oil conservator, which obviously reduces the height of the oil immersed 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 insulation performance to decline.
f. According to the performance of the above five points, it is ensured that the oil immersed transformer does not need to be changed during normal operation, which greatly reduces the maintenance cost of the oil immersed transformer and prolongs the service life of the transformer.
