Component module of oil-immersed dry type transformer

Iron core: The iron core is one of the most basic components of the dry transformer, is a part of the equivalent circuit of the dry transformer, the primary and secondary windings of the dry transformer will be on the iron core, in order to develop the equivalent circuit magnetic absorption index and reduce the eddy current loss in the iron core, the iron core is generally made of 0.35mm, the surface insulation layer of ferrite core. The iron core is divided into two parts of the iron core column and the iron yoke. The winding is coated on the iron core column, and the iron yoke connects the iron core to each other, and its effect is to close the equivalent circuit.

Winding (electromagnetic coil) : winding is also one of the most basic components of dry transformers. It is a part of the power circuit of the dry transformer, and is generally wound with a copper core wire wrapped in insulating paper or aluminum money. The winding that receives the high-voltage network is the high-voltage winding, and the winding that receives the bottom-voltage network is the bottom-voltage winding. The effect of the winding is the medium of current flow, generating magnetic flux and induced current.

Accessories: The accessories of power engineering dry transformer include fuel tank, oil pillow, tap power switch, safety gas pipe, insulation pipe, etc. Its effect is to ensure the safety and firm operation of the dry transformer.

Its main engineering is composed of the body, the oil tank, the freezing equipment, the maintenance machine equipment and the group line out machine equipment. The body comprises an iron core, a winding (turning coil), an insulation layer, a wire and a tap power switch; The oil tank includes the oil tank itself and the oil tank accessories (discharge pump, grounding device screw, car, factory nameplate, etc.); The refrigeration equipment comprises a heat pipe radiator and a cooling tower; Maintenance equipment includes oil storage tanks, oil level gauges, safety pipes, moisture absorbers, temperature measuring components and automotive relays; The team’s wiring equipment consists of high and bottom pressure waterproof bushings.
