Aluminum Transformer For Refrigerator 3 Phase Double Winding Oil Immersed Power Transformer

Aluminum Transformer For Refrigerator 3 Phase Double Winding Oil Immersed Power Transformer

Product introduction

On the basis of S9 series, the no-load loss of S11 series products is reduced by 30% on average, and the no-load current is 70-80% lower than that of S9. The core is made of imported high magnetic conductivity, low loss, cold-rolled high-quality silicon steel sheet, which reduces the no-load loss and saves energy significantly.

High safety and reliability, advanced structure, small volume, light weight, low noise, low temperature rise, anti-corrosion, reliable anti leakage measures, to prevent oil leakage.

·Structural features:

1. The low-voltage winding of an oil immersed transformer, except for copper conductor used for small capacity transformer, generally adopts copper foil winding and extraction hydro-cylinder structure; and the high-voltage winding adopts multi-layer barrel structure. These result in evenly distributed ampere-turns, small magnetic flux leakage, high mechanical strength and strong short-circuit resistance.

2. The iron core and winding are fastened separately. The machine height, low-voltage lead and other fastening parts adopt self-locking locknut and non-suspension structure, which can withstand impact during transportation.

3. The coil and iron core are treated by vacuum-drying, and the transformer oil is filtered and oiled in vacuum to reduce the water content inside of the transformer.

4. The oil tank is made of corrugated plate, which could absorb oil to compensate temperature fluctuation caused by oil volume change. Therefore, this product has no external oil tank, which significantly reduces height of the transformer.

5. As the corrugated plate replaces the oil storage tank, the transformer oil is isolated from the outside world, effectively preventing entry of oxygen and water and resulting in the decrease of insulation performance.

6.The above five performances enables the oil immersed transformer no need to change oil in normal operation, greatly reducing the maintenance cost , and extending the service life of the transformer.
