S11, SZ11 series performance characteristics and applications
  1. Core material: the core adopts high permeability grain-oriented cold-rolled silicon steel sheet, 45 degrees full oblique joints, small no-load current, low no-load loss;
  2. Coil material: the wire is made of paper wrapped or lacquer wrapped copper wire with high tensile strength, layer or pie winding, with strong short circuit resistance;
  3. Insulation structure: fully insulated, the insulation level is shown in the following table;
    Voltage Level(kV) ≤0.5 3 6 10 15 20 35 110
    Maximum voltage(kV) / 3.5 6.9 11.5 17.5 23 40.5 121
    Industrial frequency voltage(kV) 5 18 25 35 45 55 85 200
    Surge voltage(kV) / 40 60 75 105 125 200 480
  4. Regulating mode without excitation voltage regulation or on-load voltage regulation;
  5. cold pair way: oil-immersed self-cooling, oil-immersed air-cooling;
  6. The product is outdoor type, adapt to various natural environmental conditions, for power distribution and lighting power supply operation.
Introduction to transformer configuration protection devices
  1. Measuring device: measuring transformer top oil temperature:
    (1), the transformer box cover with thermometer (-20C-130C) seat
    (2), 1000-6300kVA transformer with electric contact signal thermometer;
    (3), 8000kVA and above are equipped with remote temperature measuring thermostat.
  2. Gas relay: provide operating gas alarm and tripping signal
    800kVA and above transformer configuration.
  3. Pressure release valve: to provide operating pressure signal alarm and release pressure device, 1000KVA and above configuration.
  4. Breather: to stop moisture damage transformer oil and insulation aging, to ensure that the transformer in a variety of natural conditions breathing smoothly
  5. Oil purifier: anti-oil aging and regeneration device:
    3150-6300kVA and above configuration. ( If you take anti-oil aging measures, may not be equipped with oil purifier)
