Oil-filled transformers use oil as the main insulation means of the transformer and rely on oil as the cooling medium, such as oil-immersed natural cooling, oil-immersed air cooling, oil-immersed water cooling, and forced oil circulation. Oil-filled transformers can operate as specified on the nameplate under the specified cooling conditions, but the top oil temperature should not exceed 90℃. To prevent the insulation of oil-filled transformers from aging, the top oil temperature should not exceed 85℃ frequently, and the alarm setting should be set at 80°C. The following is an introduction to the performance characteristics of oil-filled transformers.
This is the content list:
l Oil-filled transformers have high mechanical strength and strong short-circuit resistance
l Oil-filled transformers can withstand the shock of transportation
l Oil-filled transformers coils and cores are vacuum dried
l Oil-filled transformers use corrugated sheets
The low-voltage winding of oil-filled transformers generally adopts a cylindrical structure with copper foil around the shaft, except for the small-capacity copper wire. The oil-filled transformers' high-voltage winding adopts a multi-layer cylindrical structure, which balances the ampere-turns distribution of the winding, and has low magnetic leakage. The oil-filled transformers have high mechanical strength and strong short-circuit resistance.
The core and winding of the oil-filled transformers are fastened respectively. The height and low-voltage lead of the oil-filled transformers are all equipped with self-locking lock nuts. The oil-filled transformers adopt a non-suspending structure and can withstand the shock of transportation.
The coil and core of the oil-filled transformers are vacuum dried, and the transformer oil is vacuum filtered and oiled to minimize the moisture inside the oil-filled transformers.
The oil-filled transformers oil tank uses corrugated sheets, which have a breathing function to compensate for the volume change of the oil caused by temperature changes, so the product does not have an oil storage tank, which reduces the height of the oil-filled transformers. Because the corrugated sheet of oil-filled transformers replaces the oil storage tank, the transformer oil is isolated from the outside world, which effectively prevents oxygen and moisture from entering the oil-filled transformers and causes a decrease in insulation performance.
Based on the above performance, it is ensured that oil-filled transformers do not need to be changed during normal operation, which greatly reduces the maintenance cost of oil-filled transformers and prolongs their service life of oil-filled transformers.
