S11 Series 10KV stage double winding distribution

INTRODUCTION : Adopt high quality Gao Dao Ci crystal grain orientation cold press the flat of silicon steel .The distribution of magnetic circuit is even have reduced idle magnetizing current and idle wastage greatly have raised function factor and have improved the quality of power supply. Since core adopts the 3 whole oblique structures of joint gap have raised the reliability of product operation ,have reduced quality ,reduce noise ,technical properties is good .Scattered hot performance is good .Temperature rise is low. Do not pollute environment, high efficiency. The coil of low voltage skirts structure with foil, balanced performance is good .It is strong to bear the burst ability of short circuit, have raised mechanical performance and the electrical performance of product .Reliability and the safety of having guaranteed product. Adopt ripple oil box ,the heat of transformer expands cold the elasticity that shrinks by ripple flat regulates .Have no oil conservators .On case cover, have for note oil .The triune installation of oil level of instruction and pressure relief valve ,oil and air isolate .Efficiently prevent oxygen and moisture to dip transformer cause the decrease of product electrical performance , in the normal service life of having guaranteed product, need not carry out oil handling USE BZ-||/3150 Transformer performance test The testing equipment picture REFERENCE SPECIFICATIONS:Rated Power (KVA) VoltageCombination Connection Symbol Short Circuit Impedance No-load Loss (KW) Load Losses 120° (KW) No-Load Current (%) H.V (KV) Tapping Range L.V (KV) 30 6 6.3 10 10.5 11 ±5 0.4 Dyn11 Yzn11 Yyn0 4.0 0.1 0.63/0.60 2.3 50 0.13 0.91/0.87 2.0 63 0.15 1.09/1.04 1.9 80 0.18 1.31/1.25 1.9 100 0.20 1.58/1.50 1.8 125 0.24 1.89/1.80 1.7 160 0.28 2.31/2.20 1.6 200 0.34 2.73/2.60 1.5 250 0.40 3.20/3.05 1.4 315 0.48 3.83/3.65 1.4 400 0.57 4.52/4.30 1.3 500 0.68 5.41/5.15 1.2 630 Dyn11 Yyn0 4.5 0.81 6.20 1.1 800 0.98 7.50 1.0 1000 1.15 10.30 1.0 1250 1.36 12.00 0.9 1600 1.64 14.50 0.8 NOTE 1: The rated capacity of 500kVA and below the transformer, slash top of the table load apply to Dyn11, or Yzn11 connection Group, Slash the bottom of the load loss values apply to Yyn0 Connection Group. NOTE 2: According to user needs, providing high-pressure tap range is ±2×2.5% of the transformer. NOTE 3: According to user needs, can provide low-voltage transformer foe the 0.69kVA
