Structure type of dry-type transformer

It is mainly composed of an iron core composed of silicon steel sheets and a coil casted by epoxy resin. An insulating cylinder is placed between the high and low voltage coils to increase electrical insulation, and the coil is supported and restrained by pads. loose performance.
Construction performance:
⑴ Solid insulation encapsulated winding
⑵ Unencapsulated winding
Winding: Among the two windings, the higher voltage is the high-voltage winding, and the lower one is the low-voltage winding.
From the relative position of high and low voltage windings, high voltage can be divided into concentric type and overlapping type.
The concentric winding is simple and easy to manufacture, and all adopt this structure.
Overlapping type, mainly used for special transformers.
