Discussion over oil sampling techniqueused in oilimmersed transformer filledwith nitrogen

Abstract

Abstract:

Common oilimmersed transformer is notfilled with nitrogen，and its oil sample technology is also relatively mature. However, the oilimmersed transformer filled within nitrogen is rarely introduced on papers. If conventional oil sampling technology is used, it is the external air that will be sucked into the inside of the nitrogen filled oilimmersed transformer frequently, rather than the oil sample that can be moved out of it. Through the discussion over oil sampling technology and combination with engineering practice, it summarizes an oil sampling technology that is suitable for nitrogen filled oilimmersed transformer and can solve the above problems well.

Key words:

transformer, nitrogen, oilsampling
