SH15 series amorphous alloy full-sealed transformer is an epoch-making and trans-century “Green” product. The iron base amorphous alloy core has high saturation magnetic induction intensity, low loss (equivalent to 1/3-1/5 of silicon sheet), low corrective force and low excitation current and good temperature stability. The amorphous alloy is a novel energy-saving material made with a fast and abrupt-solidfication process and the metal atoms arrange in a disordered amorphous state and its structure completely different from crystal of silicon steel makes it easily magnetized and de-magnetized. When this novel material is used in transformer core, a running transformer may be easily subjected to 120 cycles/second of magnetizing and de-magnetizing process and thus no-load loss of the core is greatly reduced. If the said alloy is used in oil-immersed transformer, escape of harmful gases such as CO2, SO2 and NOX may be reduced and thus it is known as “green material” of 21 century. A Model SH-15 amorphous alloy product adopts a single-frame or three-phase five-legged spiral core. The core is clamped with sheet-formed structure and the low-voltage coil is of a foil winding type so as to render a low loss and a high short-circuit withstand. It has advanced and rational structure and its overall performances reach international.
Performance characteristics:
a. The magnetic conductive material of the iron core is amorphous alloy. Amorphous alloy is an alloy made of iron, boron and other elements as raw materials, which is sprayed and cast into strip flakes by special processes such as rapid cooling, so that the atomic arrangement of the material is disordered. Due to the soft magnetic properties of amorphous alloy, the area of hysteresis loop is very narrow, that is, it only requires very small magnetization power, so the no-load loss of transformers made of amorphous alloy materials is very small.
b. The iron core of the transformer is generally rolled into a three-phase five column structure with amorphous alloy strips, so that the height of the transformer is lower than that of the three-phase three column structure. The iron core section is rectangular, and its lower yoke can be opened to facilitate the coil package.
c. The body assembly, oil tank structure, protective device and other aspects are similar to the fully sealed oil immersed distribution transformer, which also adopts the structure without hanging core, vacuum drying, vacuum oil filtering and oil filling processes, corrugated oil tank, no oil conservator and other structures.
d. The load loss of this transformer is the same as that of S9 series, but the no-load loss of 15 series is about 75% lower than that of S9 series; The 16 series is about 80% lower than the S9 series Product advantages: Ultra low loss characteristics, energy saving, high power efficiency; Amorphous metal materials are manufactured with low energy and ultra-low loss characteristics, which can greatly save power consumption and reduce power generation of the power plant, relatively reduce CO2 and SO2 emissions, reduce environmental pollution and greenhouse effect, and are maintenance free and pollution-free; Low operating temperature, slow insulation aging and long service life of transformer; High overload capacity, high mechanical strength; When the amorphous core passes through the high frequency magnetic flux, it still has the characteristics of low iron loss and low excitation current without causing the problem of core saturation, so the SCRBH15 amorphous alloy transformer made of the amorphous core has good harmonic resistance; The investment returns quickly. Amorphous alloy transformer is a new energy-saving power distribution equipment. Its energy-saving effect mainly comes from the use of a new type of material with excellent soft magnetic energy. The iron based amorphous alloy and its strict design and manufacturing process: amorphous alloy strip material contains 78% – 81% iron, 13.5% boron and 3.5% – 8% silicon. In addition, the no-load loss of amorphous alloy transformer containing trace metal elements such as nickel and cobalt is very low, which is only 20% of S9 silicon steel transformer, The relative consumption reduction of 80% amorphous alloy transformer meets the requirements of national industrial policies and power grid energy conservation and consumption reduction.
