Transformer oil in the state of water, the transformer in the transportation, storage, use process may be entered by the outside or oil itself oxidation of water, the water generated will exist in...
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...
As know oil-type transformers are the most common form of transformers. When an oil-immersed transformer is in use, the heat generated by the coil and iron core is first transferred to the insulati...
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...
In the working process of transformer, a lot of heat will be produced, which seriously affects the performance of transformer. During the operation of transformer, the loss of winding and core wil...
