Overview
HCGC-280 Gas Chromatography Analysis System for Transformer Oil
Product Details
Detailed introduction:
HCGC-280It is an economical and applicable gas chromatography analysis system for dissolved gases in transformer oil launched by Shenzhen Huachang Haitai Technology Co., Ltd. The system uses a domestically produced host (three detectors) and a dedicated analysis process to completely separate the insulating oil in one injection7Dissolved gas components (includingH2、CO、CO2、CH4、C2H4、C2H6、C2H2）, can meetThe need for chromatographic analysis of dissolved gases in transformer oil in the power system.
Technical features:
l Large screen LCD display
l Chinese Menu
l key operation
l digitizeFIDElectronic zeroing technology enhances the anti-interference ability of instruments
Using electronic zeroing technology to achieveFIDElectronic regulation of output signal level. Due to the fact that electronic adjustment can be directly installed on the signal channel of the circuit board, the electronic noise suppression capability is improved, and there is no interference signal when connecting mechanical potentiometers. Due to the reduction of parasitic parameters, it has strong anti-interference ability.
l Thermal conductivity tungsten wire gas cutoff protection function
HCGC-280Equipped with intelligent thermal conductivity cut-off protection function, when the carrier gas pressure is below the safety threshold, the system will automatically cut off the thermal conductivity current to protect the thermal conductivity detector from damage.
