The material performance is not lower than 30ZH110 cold-rolled silicon steel sheet; the three-phase three-column stereo symmetrical structure has the most balanced three-phase magnetic circuit; each set (roll) core piece is wound by a thin steel strip on a special core winding machine, and the pressure is even Tightening; the core frame is vacuum annealed to eliminate stress and improve electromagnetic performance; the core surface is coated with epoxy paint, moisture-proof and solidified.
Low-oxygen copper paper-clad copper flat wire or QQ-2 acetal enamelled round copper wire; low-voltage coil is double-layer or four-layer round copper or new spiral, or foil high-voltage coil is multi-layer cylinder; The coil oil passage is corrugated structure, the interlayer insulation is double-sided adhesive paper; the low-pressure and high-pressure surfaces are all wrapped with epoxy resin semi-adhesive glass fiber belt to increase mechanical strength.
The triangular-structured fully sealed corrugated fuel tank is equipped with corrugated sheets for three-phase to ensure heat dissipation and compensate for the volume of expansion and contraction caused by oil temperature change; the oil level gauge with pressure relief valve on the cover surface is convenient for refueling and Observe the oil level and release the pressure safety protection against sudden overvoltage in the transformer.
The revolutionary 3D wound core is the ideal transformer technology. It offers:
Balanced magnetic circuits and exciting current in all 3 phases
Lower no-load losses
Reduced in-rush currents
Reduced exciting (a.k.a. reactive or no-load) currents
Reduced 3rd harmonic effects and total harmonics distortion
