Single phase column mounted oil immersed power transformer

Short Description:

The characteristic of this transformer is that it adopts a column mounted suspension installation method, with a small volume, low infrastructure investment, reduced low-voltage power supply radius, and can reduce low-voltage line losses by more than 60%. The transformer adopts a fully sealed structure, with strong overload capacity, high reliability for continuous operation, simple maintenance, and long service life.

Overview details

Low voltage windings of oil immersed transformers generally adopt cylindrical or spiral structures; The high-voltage winding adopts a multi-layer cylindrical structure, which balances the distribution of turns, reduces magnetic leakage, has high mechanical strength, and has strong short-circuit resistance.

The iron core and winding are each fastened with measures, and the fastening parts such as the height and low-voltage leads of the device are equipped with self-locking anti loosening nuts. They adopt a non suspended structure, which can withstand the shaking during transportation.

The coil and iron core are vacuum dried, and the transformer oil is vacuum filtered and injected to reduce the moisture inside the transformer to a low level.

The oil tank adopts corrugated sheets, which have a breathing function to compensate for the volume change of oil caused by temperature changes. Therefore, this product does not have an oil storage tank, which obviously reduces the height of the transformer.

Due to the replacement of oil storage tanks with corrugated sheets, the transformer oil is isolated from the outside world, effectively preventing the entry of oxygen and moisture, which can lead to a decrease in insulation performance
