Product Description

Introduction To oil-immersed transformer

Amorphous alloy iron core three phase oil immersed transformer 1000KVA

The performance of our S9 S10 S11 series 10kV and 35kV three-phase oil-immersed transformer conform to the standard of GB 1094-1996 “Power Transformer “ and GB/T6451-2008 “Technical Para-meter and requirements of Three-phase Oil-immersed Power Transformer”. The iron core is made of quality cold –rolled silicon steel sheet , and the coil is made of quality oxygen-free copper, featuring good outlook and safe running . The products are widely used in power transmission and distribution of industrial and agricultural power networks.

Main Function And Features of  oil-immersed
  Amorphous alloy iron core three phase oil immersed transformer 1000KVA

01)  Iron core is made of cold-rolled silicon-steel sheet with high conduction of magnetism and adopts pulling-plank structure, so that its magnetic route is short, losses and noise level is low;

02)  Compress wire is adopted for winding so losses are low and have good ability withstand short-circuit;

03)  Its active part adopts special pressing method which could ensure reliable axial pressure;

04)  The oil tank is bell type with the structure of full folding plate type, having an excellent exterior and easy for maintenance;

05)  Adopting capsule-type oil container, it can reduce oil aging to the lowest degree.

06)  Amount of  local discharged:  The apparent discharge amount is less than 80pC under the 1.5 times of rated voltage;

07)  Noise: Products of 63MVA and below is lower than 58dB(AN);

08)  Power loss: no-load loss is 30% lower than that of IEC standard;

09)  Reliability: All in-service product have no damages or oil leakage occurred;

10)  Oil tank with various kinds of structure and good appearance.

Details of oil-immersed transformer

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.

3)  The HV and MV regulation system are independently provided with voltage-regulating winding to balance the ampere turn of each winding-up, effectively lower the axial electrodynamic force generated at short-circuit of transformer and improve abrupt short-circuit withstanding capacity.

4)  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.
