Online HPLC Detection Technology In The Transformer Of The Applied Research

Power transformers are the most important equipments in electric Power system..They own very important significance.Transformer oil dissolving gases' kinds, contents and change trends are important sign to reflect transformer's status.can reflect transformer's status.Dissolved gas analyzing(DGA)in transformer oil is main method to detect transformers in electric power department.Paper fully investigates transformer online DGA history,status and development level at home and abroad.Paper fully researehes dissolved gases in transformer oil online detecting key technology in such fields as separating gas from oil,mixture gases separating and tiny combustible gases detecting.On the bases of agreat deal of investigates and researches,the paper sums up the interfere sources on locale.Ecially the paper draws some valuable conclusion that the oil cycle style,running state,configuration,oil flow distributing of transformer;position of faults and destroy degree when confirming and choosing sampling position. According to status of on the function in field,give some suggestions whice need solved in future and the development trend.
