Overview
Portable chromatograph GC-9760A for transformer oil
Product Details
In order to meet the needs of power system analysts who need to carry instruments to the fault site far away from the laboratory for transformer oil analysis, our Shanghai Huaai Chromatography Analysis Technology Co., Ltd. has newly designed the GC-9760A portable chromatograph for transformer oil. The instrument integrates all components such as computers and gas sources, and the number of components in the entire system is compressed into 2, achieving true portability.
This instrument adopts the classic three detector process, which can complete the dissolution of H in insulating oil with one injection2、CO、CO2、CH4、C2H4、C2H6、C2H2Wait for a full analysis of the content of 7 gas components, and if necessary, O can also be detected2、N2The content.
Execution standard:
GB/T 17623-2017 "Determination of dissolved gas components in insulating oil by gas chromatography"
GB/T 7252-2001 "Guidelines for Analysis and Determination of Dissolved Gases in Transformer Oil"
DL/T 703-2015 "Gas Chromatography Determination of Gas Content in Insulating Oil"
