1、 Core advantages: low loss and high energy efficiency
Amorphous alloy transformers use iron-based amorphous metals as the core material, and their atomic structure does not have long-range ordered arrangement. The energy required for magnetization and demagnetization processes is much lower than that of traditional silicon steel materials. This characteristic reduces its no-load loss (iron loss) by 70% -80% compared to silicon steel transformers, and the no-load current decreases by about 85%. Taking a 500kVA transformer as an example, the no-load loss of the amorphous alloy model is 450W/h, while the traditional S9 silicon steel transformer reaches 900W/h, with significant energy-saving effects.
2、 Environmental Benefits: Emission Reduction and Sustainable Development
Due to reduced losses, amorphous alloy transformers can reduce power generation demand, thereby reducing greenhouse gas emissions such as carbon dioxide. According to calculations, if fully applied in the distribution networks of countries such as China and India, it can save 25-30 TWh of electricity generation and reduce 20-30 million tons of carbon dioxide emissions annually. Its reputation as a 'generator free green power plant' highlights its strategic value in achieving carbon neutrality goals.
3、 Technical features: Innovative design and reliable performance
Core structure: The three-phase transformer adopts a four frame five column design, and the core is composed of four separate frames arranged in parallel. After annealing treatment and with cross yoke joints, the cross-section is rectangular. This structure can effectively suppress the third harmonic magnetic flux and reduce additional losses.
The iron core of single-phase transformers is in the shape of a "frame", and models above 500kVA adopt an eight frame stacked structure to further enhance stability.
Winding and oil tank: The winding is a rectangular cross-section double-layer or multi-layer rectangular layered structure, using copper wire winding to adapt to mechanical stress during short circuits.
The fuel tank adopts a fully sealed corrugated structure, with maintenance free design to delay insulation aging and extend service life.
Material characteristics: The thickness of amorphous alloy strip is only 0.03mm, with a lamination coefficient of 82% -86%. It is necessary to control the magnetic flux density (usually 1.3-1.35T) to avoid saturation.
Materials are sensitive to mechanical stress, so it is necessary to avoid iron core load-bearing during design to ensure low loss characteristics.
