10KV on-load voltage-regulating oil-immersed distribution transformer
I. Scope of application
On-load voltage-regulating oil-immersed distribution transformer is a kind of transformer that can automatically or manually operate the on-load switch under load conditions, or achieve voltage regulation through a remote voltage regulator controller; it is an upgraded product developed on the basis of conventional oil-immersed distribution transformers; it is suitable for areas, enterprises or places with relatively stable voltage requirements where the grid voltage fluctuates more frequently; transformers with rated capacity ranging from 200KVA to 2500KVA are suitable for AC 50Hz/60Hz, working voltage 10KV and below power systems, as 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.
Voltage: When the grid voltage fluctuates greatly, the on-load voltage regulator can be used to adjust the voltage under load to provide a stable output voltage.
