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...
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...
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...
Pressure Relief devices/valves are typically classified in the Transformer industry as safety or protection devices transformer pressure relief device valve for liquid-immersed transformers open in...
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...
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...
