#Three Phase Dry Transformer#Dry Type Power Transformer#50kva Dry Type Transformer
630kva Dry Type Epoxy resin transformer
Dry-type transformer main materials:
1. Iron core
The high-quality cold-rolled grain-oriented silicon steel sheet is adopted, and the iron core silicon steel sheet adopts a 45-degree full oblique joint, so that the magnetic flux passes along the joint direction of the silicon steel sheet.
2. Winding form
⑴ Winding;
⑵ Epoxy resin plus quartz sand filling and pouring;
(3) glass fiber reinforced epoxy resin casting (ie thin insulation structure);
(4) Multi-strand glass fiber impregnated with epoxy resin winding type (generally 3 is used, because it can effectively prevent the poured resin from cracking and improve the reliability of the equipment).
3. High voltage winding
Generally, a multi-layer cylindrical or multi-layer segmented structure is adopted.
