The structural design of amorphous alloy dry-type transformers revolves around "energy saving, safety, and stability". Compared with traditional dry-type transformers, the key differences are concentrated in the core materials and modular layout.

1. Amorphous alloy iron core

   The iron core is the core of energy conversion in transformers. Amorphous alloy dry-type transformers are made by rolling iron-based amorphous alloy strips, replacing traditional silicon steel sheet iron cores. The atomic arrangement of amorphous alloys has no fixed pattern, with extremely high magnetic permeability and extremely low coercivity, which can significantly reduce hysteresis loss and eddy current loss, which is the core source of their energy-saving advantages. The iron core adopts a fully inclined joint and multi-stage stacked structure, combined with a dedicated clamping device, which ensures smooth magnetic circuit and reduces operating noise. The overall loss is 30% -50% lower than that of traditional silicon steel sheet iron core transformers.

2. Epoxy resin cast winding

   The winding is made of high-quality oxygen free copper wire, and the outer layer is formed by epoxy resin vacuum casting process to form a fully sealed insulation structure. This design endows the winding with excellent insulation performance, mechanical strength, and moisture and corrosion resistance, enabling stable operation even in humid and dusty environments. The surface of the winding is smooth and dense, without bubbles or cracks, which can effectively resist the impact of short-circuit current. It also has strong flame retardancy and does not produce toxic gases when exposed to fire, meeting the fire prevention requirements of dry-type transformers.

3. Modular enclosure and heat dissipation design

   The enclosure is made of cold-rolled steel plate treated with anti-corrosion coating, with a compact structure and high modularity. The interior is divided into winding area, wiring area, and heat dissipation area, with a clear layout for easy maintenance. The cooling system adopts a dual-mode design of "natural air cooling+forced air cooling". During normal operation, it relies on the ventilation louvers of the box for natural heat dissipation. When the load is high, it automatically starts the built-in cooling fan to ensure stable temperature of the equipment under rated load and avoid affecting performance due to overheating.

4. Complete auxiliary protection structure

   Built in multiple protection devices such as overload, short circuit, and lightning protection, combined with an insulation grounding system, with a grounding resistance of ≤ 4 Ω, effectively avoiding the risk of electric shock and equipment failure. The wiring terminal adopts a closed protection design with clear labeling, which not only prevents accidental contact but also facilitates wiring debugging; The protection level of the enclosure can reach IP44-IP54, which can adapt to various indoor and outdoor installation environments and resist dust and rainwater erosion.

Relying on unique structural design, amorphous alloy dry-type transformers have demonstrated significant advantages in performance and are suitable for the core requirements of modern power distribution.

1. Ultimate energy saving

   The low loss characteristic of amorphous alloy iron core is its core advantage. Its no-load loss is only 1/3-1/2 of that of traditional silicon steel sheet dry-type transformers, and the load loss is greatly reduced by optimizing the winding structure. Taking 1000kVA products as an example, amorphous alloy dry-type transformers can save thousands of kilowatt hours of electricity annually. Over long-term operation, they can save users considerable electricity expenses, which is in line with the national "dual carbon" policy and green distribution concept.

2. Safe and reliable

   As a dry-type transformer, its oil-free design eliminates the risk of oil leakage and fire from the root. Combined with the flame retardant properties of epoxy resin windings, it is particularly suitable for scenarios with high personnel density and fire prevention requirements (such as high-rise residential areas, hospitals, data centers). The equipment has strong short-circuit resistance, can withstand frequent start stop and load fluctuation impacts, has a long average fault free operation time, and can have a service life of over 20 years under normal maintenance.

3. Low noise and environmental protection

   The amorphous alloy iron core has a small magnetostriction coefficient, combined with the iron core clamping device and box sound insulation design, the operating noise is ≤ 55dB, far lower than traditional transformers, and will not cause noise pollution to the surrounding environment. At the same time, the equipment has no oil pollution, no toxic gas emissions, and the scrapped iron core material can be recycled, which meets environmental protection requirements and is an ideal choice for green power distribution.

4. Flexible adaptation

   The product capacity covers 50kVA-2000kVA, and the voltage level supports 10kV/0.4kV. The capacity and voltage parameters can be customized according to user needs. It can meet the conventional power distribution needs of residential areas and commercial centers, as well as adapt to the electricity requirements of special scenarios such as factory production lines, photovoltaic power stations, charging piles, etc., especially suitable for projects with dual high requirements for energy conservation and safety.
