Amorphous alloy transformers can be identified through the following methods:

　　Check the Nameplate Information: The model of an amorphous alloy transformer usually contains specific identifiers. For example, in the model S(B)H15-M-□/□, the "H" represents amorphous alloy, and "15" indicates the loss level. Additionally, the nameplate will also indicate relevant parameters such as rated capacity and rated voltage, which can be used as a reference for identification.

　　Observe the Appearance Structure

　　Core Structure: The core of an amorphous alloy transformer is typically a three-phase five-column wound core. The three-phase five-column core is composed of four single-frame wound cores combined in the same plane, and the cross-section is rectangular. For single-phase transformers, it is a single-frame wound core, and the core can be opened, which is beneficial for coil assembly.

　　Coil Shape: Since the amorphous alloy core is rectangular, the coils of the amorphous alloy transformer are also rectangular. The high and low voltage coils are nested and wound.

　　Tank Structure: Amorphous alloy transformers often adopt a fully sealed structure, canceling the oil conservator and moisture absorber. The volume change of the oil is compensated by the elasticity of the corrugated sheets of the tank.

　　Test the Loss Characteristics: The no-load loss of amorphous alloy transformers is 70%-80% lower than that of traditional silicon steel transformers. If conditions permit, the no-load loss can be tested. If the measured no-load loss is much lower than the standard value of traditional transformers, it may be an amorphous alloy transformer.

　　Check the Material and Thickness of the Core: The core of an amorphous alloy transformer is made of amorphous alloy materials, mainly composed of elements such as iron, silicon, and boron. The thickness of the amorphous alloy strip is extremely thin, usually only about 0.025mm, which is less than one-tenth of the commonly used silicon steel sheet. If possible, by observing the core material or measuring its thickness, it can be determined whether it is an amorphous alloy transformer.

　　Evaluate the Noise Level: Due to the low loss of amorphous alloy transformers, the noise generated during operation is also relatively small. In an environment with the same load, if the noise of the transformer is significantly lower than that of other transformers, it may be an amorphous alloy transformer.
