The laminated core sheets 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 noises.3) 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 section of oil tank is tightened with counter-pressure bolts. The upper iron and the upper section of oil tank are fixed at three locations. Hence the body inside the oil tank can withstand the vibration during transportation without any shift.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 accessories1) 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.Typical projectsFeatures:1) Low loss2) Low noise3) High efficiency4) Low partial discharge5) Strong mechanical strength and short-circuit withstand ability.6) Operation reliability7) Easy maintenance8) Pretty outline and compact structure9) 100% guaranteed no leakageBrief specification1) Voltage class: 6~110 KV2) Capacity: 630 kVA to 120, 000 kVA3) Short-circuit impedance: 4.5~21%4)Losses: No-load losses is fully comply with IEC standard requirementsTypeRated Power (kVA)Rated Voltage (Line Side) V Rated Voltage (Valve Side) VConnection SymbolActive Part Weight (kg)Oil Weight (kg)Total Weight (kg)Overall Dimension (L*W*H) (mm)ZSSP-800/1080010000400Dyn11158066032402160*1625*1855ZSSP-2000/35200035000400Yyn03320128057352600*1260*2740 ZSSP-4000/35400035000950Dd0y115410204095402570*1745*2720 ZSSP-6300/356300350001000D( ±7.5 °)dyn86004860182603340*1875*3370 ZSSP-7000/35700035000950Dd0y1185703390147003185*985*3475 ZSSP-8000/22800022000950 Dd0y1186403340147103210*1905*3375 ZSSP-8000/35800035000950Dd0y11 91703590155203340*1870*3490 ZSSP-9000/35900035000950 Dd0y1199204070157403240*1915*3720 ZSSP-10000/3510000350001000 D( ±7.5 °)dyn110904400188503410*1915*3845
