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...
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...
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...
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 ...
