Three-phase Two Winding 100MVA  On-load-tap-changing 220KV Electrical Transformer

Product Description

220kv,110KV and 66kv low-loss series transformer is our independently new generation of transformers on the basis of absorption of domestic and foreign advanced technology ,which features low local discharge ,low loss,low noise ,high reliability ,strong protection against abrupt short circuit .its excellent performance has been recognized by wide users and highly appraised by experts .The full-sealed suspending-cover free products sell well nationwide.

Amount of local discharge:The apparent discharge amount under1.5 times of rated voltage is less than 80 PC.

 

 

Coil

The high-voltage coil adopts an interleaved 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 .

In the transformer winding there is a zigzag oil guide structure so as to fully cool all areas inside 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.

  The winding adopts radial “0”margin design ,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 tighly matched to ensure extremely good compactness and concentricity of the entire winding.
