Products Description


Load capacity regulating power transfommer produced by us is a new type energy saving distribution transformer, theproduct has two kinds of rated capacity, the principle is that in the case of uninterrupted power supply, the transformetreck the load changers through the intelligent system, automatically change its capacity according to the size ofelectnical load.lt solves the problem that seasonal load variation of 10kV distribution network which cause high lossof transfomer, and overcomes the problem that off-load capacity regulating power transformer is manually adjustedcapacity under outage conditions to cause difficult operation and maintenance.




Product features
After automatically capacity regulating, transformer will be run at reasonable situation.
Through capacity regulating, no-load loss of transformer is comprehensively reduced by 50%-70%, reactive powerloss of grid is reduced by more than 20%, and reactive power line loss is reduced by more than 20%.
Switching process of capacity regulating is completed within 20ms-40ms, which could keep the power supplycontinuity of low side.

Winding:
1) The high-voltage (HV) coil adopts an interleaved-continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed. All stays and pads are chamfered to keep highly reliable insulation.

2) In the transformer winding there is a zigzag oil guide structure so as to fully cool all areas inside the winding, lower the
temperature rise of the winding and the hot points of the winding and prolong the service life of insulation. The HV and MV
regulation system are independently provided with voltage-regulating winding to balance the ampere turn of each winding,
effectively lower the axial electrodynamic force generated at short-circuit of transformer and improve abrupt short-circuit
withstanding capacity.

3) The winding adopts radial "0" margin designed, between the core and the paper sleeve of LV winding, and between the LV, HV, voltage-regulating windings, as well as before insertion of stays and shroud plate they are fully dried and tightly matched to ensure extremely good compactness and concentricity of the entire winding.

Oil tank and accessories:

1) The tank wall adopts wide steel sheet, which will be folded into corrugated structure without splicing, in this way welds are decreased and mechanical strength is enhanced, meanwhile, the corrugated wall has diverging effect, and thus plays a role in decrease of noise. The routing troughs and control cabinets of the secondary circuit are all made of stainless steel, so the entire transformer has a simple and good looking.

2) All sealing surface use quality sealing material and are precision-machined.

3) On the edge of the tank there are double sealing grooves, and the outer sealing material is used to shade the atmosphere and ultra-ray to protect the inner sealing being damaged, thus at utmost prolonging service life and enhancing reliability of the seal.
