6 Cheryong Power Products Transformer Products High-Efficiency Amorphous Transformer The Amorphous transformer is a power conversion equipment and a High Efficiency Energy and Power Saving Transformer which reduces the rate of no-load loss more than 75% comparing to the existing transformer due to the adoption of amorphous metal in the steel core instead of the existing grain oriented silicon steel. 6 High-Efficiency Amorphous Transformer Amorphous Metal The Amorphous metal is an amorphous magnetic material created from molten metal which is mixed with Fe, B, Si and others through a rapid cooling process(10 6 /sec) * The array of atom is irregularly arranged into amorphous state like liquid state(random structure) * Due to the advantage that atom s rotation is easy to cope with the variation of magnetic field, amorphous metal reduces the hysteresis loss more than silicon steel with crystal structure * Amorphous metal has the high natural resistance(3 times higher than silicon steel) and the thin and thickness of material (about one tenth of silicon steel) enables amorphous metal to reduce the eddy loss - Hysteresis loss : Friction loss occured between magnetic particles when a magnetic flux passes through steel core - Eddy loss : Resistance loss occured from eddy current when a magnetic flux passes through steel core - No-load loss : Energy loss resulting from the primary side of transformer is powered regardless of load existence. This loss always occurs in steel core in energizing condition - Load loss : Variable loss with load factor in the transformer winding. This loss is in proportion to square of load factor. This load loss is zero in case of no-load Amorphous Metal Structure Grain Oriented Silicon Steel Structure Noncrystalline Amorphous Metal Crystalline Silicon Steel

7 CHERYONG Electric Co., Ltd. Characteristic Comparison of Iron Core Material Characteristic Amorphous metal Grain Oriented Silicon steel Reference Magnetic property Iron core loss(w/kg) Characteristic of excitation(va/kg) Magnetization of saturation(25 ) Resistivity(µ -cm) Amorphous metal: 1.35 Tesla Silicon steel: 1.7 Tesla Physical property Thickness(µm) Specific gravity(g/cc) Hardness(Hv) ~ Hysteresis curve A hysteresis curve decides the main characteristics of a magnetic material and the cross section of a looped curve shows a hysteresis loss. Because the coercivity of amorphous metal is less than silicon steel and the high permeability of amorphous metal comparing to silicon steel, it decreases hysteresis loss in natural. B(T) Silicon Steel Amorphous Metal H(A/m) Hc 7 Advantages of Amorphous Transformer B(T) = Magnetic flux density, H(A/m) = Magnetic field intensity, B/H = Permeability(Slope of Curve) * Miniaturization : Reduce overall dimension by the special winding structure * Low Heat Generation - Require the smallest space for installation - Decrease secular variation of the winding & insulating materials caused by passing years - Enable minimization of rising temperature in winding to increase capability for overload * According to loss reduction, get the operation & maintenance cost of the transformer reduced and make transformer life more extended * The excellent magnetic characteristics in the high frequency and harmonics band provide high efficiency and miniaturization * Environmental effects - Reduce heat emission by power consumption and prevent global warming - Environmental conservation due to the reduction of power plant construction - Reduce emission of harmful gases * Certificated by high efficiency energy appliance High-Efficiency Amorphous Transformer
