Insulating Oil Dissolved Gases Analysis Transformer Oil Dga Analysers And Monitors For Meter 9 Gases

◆Analysis of dissolved gases in insulating oil

Content determination of dissolved gases in insulating oil by gas chromatography is set, the power supply enterprise to judge the oil filled power equipment in the operation of the existence of latent heat, discharge fault, in order to ensure the effective operation of the power grid safety, It is also one of the necessary means of testing equipment for oil-filled electrical equipment manufacturers.HZGC-1212A transformer oil chromatographic analysis system using three detector process standard recommend, a sampling can complete component of dissolved gas in insulation oil (including hydrogen, oxygen, methane, ethylene, ethane, acetylene, carbon monoxide and carbon dioxide) full content analysis.

◆Determination of gas content in insulating oil

Insulating oil gas content is an important index of oiliness supervision. At present, according to the DL/T450-1991 method of making carbon dioxide elution method is suitable for determining not only acid gas containing oil, according to the DL/T423-91 method for vacuum pressure difference method for vacuum instrument is not easy and the existence of the limitations.HZGC-1212A transformer oil spectrum analysis of process design of the system fully in line with the People's Republic of China electric power industry standard DL/T 703-1999< gas="" content="" in="" insulating="" oil="" by="" gas="" chromatography="" method="" in="" the="" chromatographic="" process="" design.="" the="" machine="" is="" equipped="" with="" the="" provisions.="" the="" thermal="" conductivity="" detector="" with="" high="" sensitivity="" and="" hydrogen="" flame="" ionization="" detector,="" and="" a="" nickel="" catalyst="" converter,="" can="" be="" dissolved="" in="" transformer="" oil="" nine="" gas="" components:="" hydrogen,="" oxygen,="" nitrogen,="" carbon="" monoxide,="" carbon="" dioxide,="" methane,="" ethane,="" ethylene,="" acetylene="" measuring.="" its="" performance="" to="" meet="" the="" requirements="" of="" gas="" insulated="" dl/t="">< chromatograph="" oil="" and="" gas="" content="" in="" gas="" chromatography="">
