10kV S11 Three-phase Full-sealing Oil-immersed Distribution Transformer

10kV S11 Three-phase Full-sealing Oil-immersed Distribution TransformerPerformance and characteristic of 10KV and S11 type transformer:Comparing with general oil-immersed power transformer, the full-sealing power transformer cancels conservator, and uses fin plate of corrugated tank as heat dissipation components.The fin plate can expands as the volume of transformer oil to isolating internal transformer from external atmosphere for avoiding degradation, moistened insulation and aging.The core adopting high quality cold silicon sheet improves flux density condition in core and reduces sound and loss.The winding adopting high strength enameled wire(or paper covered wire) and cylindrical structure with uniform ampere-turn and reasonable insulation structure has a strong capacity of anti-short circuit.All of the fasteners adopt check nut to insure that they are not loose during operation after long distance transportation. The transformer whose surface of tank adopts 3-proofing (coating of damp proof, mould proof and salt spry proof) after parkerizinis is widely used in some nasty conditions such as metallurgy, mine and petrochemical.----BASIC PARAMETERSHigh Voltage:              6/6.3/10/10.5/11/20KV Low Voltage:               0.4KV Connection Symbol:   Yyn0 or Dyn11 Number of phases:    ThreeS11-M ,10KV oil-immerses off-circuit distribution transformertypeVoltage combination andtap range(KW)VectorgroupNo-loadloss(KW)On-loadloss(KW)No-load current(％)Short circuit  impedance(％)Trackgauge(mm)HVTaprangeLVS11-M-3066.31010.511±5％或±2x2.5％0.40.69Yyn0或Dyn110.100.63/0.601.844.0400x400S11-M-500.130.91/0.871.6S11-M-630.151.09/1.041.52S11-M-800.181.31/1.251.52S11-M-1000.201.58/1.251.44S11-M-1250.241.89/1.801.36S11-M-1600.282.31/2.201.28550x550S11-M-2000.342.73/2.601.20S11-M-3500.403.20/3.051.12S11-M-3150.483.83/3.651.12S11-M-4000.574.52/4.301.04660x660S11-M-5000.685.41/5.510.96S11-M-6300.816.200.884.5S11-M-8000.987.500.8820x820S11-M-10001.1510.30.8S11-M-12501.3612.00.72S11-M-16001.6414.50.64(1)For the transformer whose capacity is 500KV and below, the on-load loss value above diagonal line is suitable for Dyn11 connection, and the value below diagonal line is suitable for Yyn0 connection.(2)Overall dimensions are for reference only, and we have a right to change it.(3)We can produce transformers with special performance parameter according to requirements of users.S11 10KV oil-immerses on-load voltage regulation transformer typeVoltage combination andtap range(KW)Vector groupNo-loadloss(KW)On-loadloss(KW)No-loadcurrent(％)Short circuitimpedance(％)Tractiongauge(mm)HVTap rangeLVSZ11-10066.31010.511±4x2.5％0.40.69Yyn0或   Dyn110.231.51.44.0660x660    SZ11-1250.271.81.4SZ11-1600.322.21.3SZ11-2000.382.911.2SZ11-2500.453.421.1SZ11-3150.544.11.1SZ11 -4000.644.961.0SZ11 -5000.775.91.0SZ11-6300.967.270.94.5820x820SZ11-8001.128.890.8SZ11-10001.3610.430.8SZ11-12501.5612.40.7SZ11-16001.9214.790.6
