Product Advantages


Core:


The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity, and 45° mitring and steps overlapping structure is used for core production, enable the effectiveness of reducing no-load loss and no-load current.

HV winding:


HV winding is manufactured with high quality copper conductor, adopting optimized structure to improve electric distribution. Lightning impulse wave process is carried out for calculation and analysis, thus to improve transformer's anti-lightning impulse capability.

LVwinding:


LV winding is manufactured with high quality foil conductor, so the ampere-turn balance is excellent and the transverse magnetic flux leakage is low. The anti-short circuit capability is thus greatly improved. Oil conduit is rationally designed in the windings to increase winding's heat dispersion surface, effectively reduce temperature and improve transformer's overload capability.

 

Introduction 

 

By winding number

 

35 kV class 3-phase two-winding power transformer

 

By tap-changing

 

35 kV class on-load tap-changing power transformer

 

 

35 kV class off-load tap-changing power transformer

 

 

Insulation Structure:


The transformer adopts class-A insulation. The HV and LV windings are arranged in concentric way. Between the windings are oil-clapboard insulation structure built with paper cylinder and small oil conduit.

Tank:


The tank conservator tank type with radiator fins. 


Executed Standards:
IEC60076

 

Oil inspection

  • the oil quality inspection on tank, on-load switch, conservator
    Take the oil sample from teh bottom of the tank and on-load switch, measure dielectric strength (kV/mm), it should not be less than 50kV/2.5mm (VDE 2.5mm electrode). For more details, please refer to “Instruction for transformer oil”
  • Oil level in conservator
    Inspect whether the temperature of oil is coincident with the oil gauge indicated.
    NOTE: When measuring oil temperature, the temperature sensor on cover can not be exposed under the strong sunlight directly.
  • Transformer deflation
    -- After oiling, or transformer has been placed for a long time, the transformer needs to be deflated.
    -- Open the deflated screw until the oil spill and no bubble appears.
    -- Recommendations for preparing some cloth to absorb oil.
    -- Sequence for deflating.
    Radiator Each deflated screw on the top of the radiator
    Cover Each deflated screw on the hand-decking
    On-load Switch Each deflated screw on the on-load switch and the tope of the oil
    absorbing pipe.
    Bushing Deflated screw on the bushing
    Gas relay Deflated screws on the gas relay
    Pressure release valve Deflated screws on the crust.
    **-Details are on teh instruction manual of each parts.
