10KV amorphous alloy oil-immersed distribution transformer
I. Scope of application
The core of the amorphous alloy oil-immersed distribution transformer is made of amorphous alloy material, with a three-phase five-column structure; the transformer loss is particularly low, and its no-load loss is 75% lower than that of conventional oil-immersed distribution transformers, and the annual operating cost is reduced by 22.7%, with a very significant energy-saving effect. It adopts a fully sealed maintenance-free structure, which is safe and energy-saving; the transformer with a rated capacity ranging from 30KVA to 2500KVA is suitable for AC 50Hz/60Hz, working voltage 10KV level power system, as a substation equipment in the fields of power transmission and distribution, infrastructure, public transportation, construction and housing, industry, information technology and new energy.

4. Product Advantages
Core: 45° full-slant step joint process is adopted, which effectively reduces no-load loss, no-load current and core noise;
The clamp and pull plate structure are used to make the core as a whole stable and firm, thereby improving the ability to resist short circuit and impact.
Coil: High voltage adopts cylindrical type, low voltage adopts cylindrical type or foil type, which improves the ability to resist short circuit;
An oil guide structure is provided inside the winding to improve the oil flow path, thereby reducing temperature rise and improving load capacity.
Oil tank: It is a fully sealed bell-shaped structure, and the oil tank reinforcement iron adopts corrugated folding plate structure, with fewer welds and high mechanical strength;
The cooling device adopts a plate radiator, which has faster circulation speed, high heat dissipation efficiency, and improved overload capacity.
Body: All insulating parts and the welding parts of the winding head and lead wire are rounded.
The upper and lower parts of the body are positioned with rigidity to ensure that the body does not shift under various transportation conditions.
Energy saving: no-load loss is reduced by about 75% compared with conventional oil-immersed distribution transformers.
