The amorphous alloy is a novel energy-saving material made with a fast and abrupt-solidification 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 demagnetized. When this novel material is used in transformer core, a running transformer may be easily subjected to 120 cycles/second of magnetizing and demagnetizing 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 21st century. A Model SH13 amorphous alloy product adopts a single-phase or three-phase five-legged spiral core. The core is damped with sheet-formed frame 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 national structure and its overall performances reach international advanced level. |
