为s9-M/WF1系列分三个阶段的石油浸改变

•Main Functions And Features Transformer core,Transformer winding insulation structure and internal structure is same as S9-M ,S10-M,S11-M Series . Oil tank: the oil tank is made by fine cold-rolled steel sheets; corrugation oil tank automatic production line is adopted ; rust cleaning and phosphate treatment are applied for the surface of the oil tank, then , antiseptic coating material is applied on the surface, which can meet the requirements for petroleum and chemical industry(much oil stain and many chemical substances). In addition , the corrugations not only possess heat radiation function , but also meet the requirement for oil expansion and oil contraction under normal performance . The isolation from air guarantees a low aging speed of oil and a long life expectancy of transformer. Cover: the cover is manufactured by welding fine steel sheets: rust cleaning and phosphate treatment are applied for the surface to avoid the corrosion caused by oil stain and chemical substances; the cover possesses a pretty external appearance; the installation and maintenance for the cover is very easy and convenient , so it can be used in places where the outdoor surrounding is not very good. Standard: the technical standards for this transformer are GB1094.1 2-1996, GB1094.3,5-2003. The technical standards for our S9-M Series transformer meet the national standards of S9 series transformer. •Main Technical Parameters for 10kV S9-M/WF1 series three-phase Oil-immersed transformer exclusive for petrifaction: Rated power (kVA) High Voltage (kV) H.V Tap range Low Voltage (kV) Connection Symbol Short-Circuit Impedance (%) No-load Loss (kW) On-Load Loss (kW) No-load Current (%)Gauge (mm)306 6.3 10 10.5 11±5% ±2×2.5%0.4Yyn0 Dyn1140.130.62.1550×660500.170.872550×660630.21.041.9550×660800.251.251.8550×6601000.291.51.6550×6601250.341.81.5550×6601600.42.21.4550×6602000.482.61.3550×6602500.563.051.2660×6603150.673.651.1660×6604000.840301660×6605000.965.11660×6606304.51.26.20.9820×9008001.47.50.8820×90010001.710.30.7820×90012501.95120.6820×90016002.414.50.6820×90020002.619.80.61070×107025003230.61070×1070
