Performance of oil immersed transformer

A, oil immersed transformer low-voltage winding in addition to small capacity using copper wire, the general use of copper foil around the cylindrical structure; high-voltage winding using multi-layer cylindrical structure, so that the winding ampoule distribution balance, magnetic flux leakage Small, high mechanical strength, anti-short circuit capability.

B, core and winding each with a tightening measures, the device body height, low voltage lead and other fastening parts are self-locking lock nut, using a non-hanging structure, can withstand the transport of the shock.

C, coil and core using vacuum drying, farady transformer oil using vacuum oil and oiling process, so that the transformer internal moisture to a minimum.

D, fuel tank with corrugated sheet, it has a breathing function to compensate for changes in temperature caused by changes in the volume of oil, so the product is no oil conservator, obviously reduced the height of the transformer.

E, because the corrugated plate replaced the oil conservator, so that the transformer oil and the outside isolation, so as to effectively prevent the oxygen, water into the lead to the decline in insulation performance.

F, according to the above five performance to ensure that the oil-immersed transformer in the normal operation does not need to change the oil, greatly reducing the maintenance costs of the transformer, while extending the life of the transformer.
