The thermal stability of the insulation material is the main factor affecting the life and overload capacity of the oil-immersed transformer. By explaining the preparation process, physical and che...
Foil coil is mainly used for small and medium-sized transformers with capacity less than 2000KVA. The advantages of foil coil are: good mechanical strength, not easy to deformation, can withstand s...
When the transformer is in operation, heat is generated due to copper losses in the windings and iron losses in the core. The removal of heat from the transformer is known as cooling of the transfo...
A series of problems, such as larger diameter, the formation of waves on the cylinder, the deviation of the verticality of the assembly, and the unqualified performance after annealing during proce...
I.Cause of Partial Discharge
The transformer insulator, metal body and so on are often with some sharp angle and burr, so the electric charges under the action of electric field intensity will conc...
Distribution transformers normally have ratings less than 200 kVA,[2] although some national standards can allow for units up to 5000 kVA to be described as distribution transformers. Since distrib...
