Transformer winding machine is the most important core production equipment in the production process of transformer. Its winding performance determines the electrical characteristics of transforme...
The coil of transformer is an important part of transformer. It is said that the heart of coil type transformer is very important to transformer. In the transformer, the coil is the part of the cir...
effect of temperature on high pressure test
The change of temperature will fully affect the insulation resistance, so when the external temperature continues to rise, the movement of molecules and ...
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...
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...
