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.
