Fully Sealed Oil Immersed Type Transformer Low Noise High
Efficiency Energy Saving
Compared with the oil storage tank in traditional oil-immersed
power transformer, our 12kV fully-sealed transformer has corrugated
plate, which adjusts the oil automatically. The oil is isolated
from the air, showing no signs of deterioration nor aging problem.
That enhances the operation reliability, free maintenance under
normal operation.
In addition, the 12kV transformer has features of low loss, low
noise and high efficiency, which guarantee good energy-saving with
less pollution to the environment.
Structural Features
- The transformer core is made of folded import high-quality
cold-rolled silicon steel sheet, which greatly reduces no-load loss
and no-load current. The core is bound to ensure the compactness
and reduce noise.
- The high and low voltage winding is made of oxygen-free copper,.
The low voltage winding of 500KVA and below is of double-layer
barrel structure, and of 630kVA and above is of double helix or
four helix structure. The high-voltage winding normally adopts
multi-layer barrels structure.
- Dyn11 method is applied to the transformer connection to reduce the
influence of harmonics on the power grid and improve the quality of
power supply.
- The transformer is a fully-sealed structure, which can extend its
service life, free of core -lifting and maintenance.
- The measured noise value is lower than the standard. After normal
transportation, this series of transformers can be installed with
relevant parts and components without core- lifting inspection, and
can be put into operation after passing the acceptance test.
