Overview
HCC-101 Transformer Oil Analysis Chromatography Column
Product Details
Detailed introduction:
Specialized for Oil Chromatography Analysis of Power System Transformers
HCC-101typeSingle column injection chromatography column
At present, for the analysis of dissolved gases in transformer oil, the needle injection method is generally used, which can reduce analysis errors, meet the requirements of oil sample analysis with low degassing volume, and be easy to operate. The conventional single injection dual column parallel diversion method and the one injection six way valve switching method have certain defects:
|
Defects of one needle injection dual column parallel diversion method |
Defects in the six way valve switching method for one needle injection |
|
1 The diversion ratio may change during operation 2 Separation using a molecular sieve columnCO2The peak outflow time is long, and the column is prone to failure 3 O2The existence ofCOFront out shoulder peakCH4Front load peak, interference measurement |
1 Analysis of baseline mutation caused by valve switching and its impact 2 use13XMolecular sieve columns have a short service life and are prone to moisture adsorptionCO2And failed 3 There is a high content ofCO、CO2answerCH4、C2H4The impact of separation 4 C2H2Low detection sensitivity |
The above defects are mainly caused by the separation performance of the chromatographic column and the analysis process.
Using a single column to analyze dissolved gases in transformer oil can overcome these deficiencies, simplify the analysis process, reduce instrument manufacturing and operating costs, and prevent unstable factors caused by other complex processes.
Developed by Shenzhen Huachang Haitai Technology Co., LtdHCC-101Single column single injection chromatography column and process overcome the shortcomings of the above process. Single column single injection can achieve8Completely separate within minutesH2、O2、CO、CO2、CH4、C2H6、C2H4、C2H2Waiting for components.
This process can significantly reduce high concentrationsCO、CO2answerCH4、C2H4The impact of measurement has expandedCO、CO2Linear detection range significantly increases high concentrationCO、CO2Accuracy of measurement.
HCC-101Suitable for use with various models of gas chromatographs currently used in the power system.
