Why vacuum pump should be adopted for oil-filling in transformer ? Becuase vacuum condition can avoid oil being oxidized that would decrease the insulation degree of tranfromer. Transformer above 220kV must adopt vacuum oil-filling. It is suggested to be used for 110kV tranformer. Oil filling wor...
