QUNENG SCB10-250 SCB10 series resin dry-type transformer

Dry-type transformer: relies on air convection for cooling, generally used for local lighting and electronic circuits. Transformers such as mechanical equipment, in the power system, general steam turbine transformers, boiler transformers, ash removal transformers, dust removal transformers, desulfurization transformers, etc. are all dry-type transformers, the transformation ratio is 6000V/400V and 10KV/400V, used for rated voltage 380V load. Simply put, a dry-type transformer refers to a transformer in which the iron core and winding are not immersed in insulating oil.

Structural features of dry-type isolation transformers:
iron core
The high-quality cold-rolled grain-oriented silicon steel sheet is used, 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.
Winding form
1, winding
2, 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)
