High safety performance 110kv 31.5mva Electric Power Transformer

Product Description

 

110kv SF9 NLTC

General

 

Amount of local discharge: The apparent discharge amount under 1.5 times of rated voltage is less than 80pC.

Noise: Product of 63MVA and below is lower than 58dB(AN).

Power loss: no-load loss is. 30% lower than that of IEC standard.

Reliablity: All in-service products have no damages or oil leakage occurred.

Short circuit withstanding: Model SFZ11-50000/132 smoothly passed the short-circuit withstanding test of the national transformer quality supervision and inspection center and also passed Holland "KEMA" quality Control syestem.

 

Coil

 

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 inulation.

In the transformer winding there is a zigzag il 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. 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 styas and shroud plate they are fully dried and tightly matched to ensure extremely good compactness and concentricity of the entire winding.

 

Core

The core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet and the material is cut with advanced Germany Geoge GmbH automatic shear line with the cut burrs controlled within 0.02mm.

The silicon sheet fabrication adopts"no-upeer yoke-lapped" technology and all lapped joints of the silicon sheet are 45 full-miters. The laminated core sheet are integrally pressed and adhered with epoxy resin to make the three-leg two-yoke core a strong and flat integral one with good verticality precision, this effectively improves no-load performance and reduces noise.

Bracing plates are used as support between coil leg and inner coil. The iron yoke is tied with epoxy resin-impregnated glass fiber band, and the lower iron yoke and the lower section of oil tank is tightened with counter-pressure bolts. The upper iron yoke and the upper section of oil tank are fixed at 3 locations. Hence the body inside the oil tank can withstand the vibration during transportation wihtout any shift.

 

Oil tank and accessories

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 troughts and control cabinets of the secondary circuit are all made of stainless steel, so the entire transformer has a simple and good looking.

All sealing surfaces use quality sealing material and are precision-machined.

On the edge of the tank there are double sealing grooves, and teh 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 reliablity of the sea.
