Introduction to Analysis of Dissolved Gas in Transformer Oil:

GC-9280The specialized gas chromatograph for dissolved gas analysis of transformer oil (insulation oil) is designed and manufactured according to national standards for power specific gas chromatographs. Dissolved gas（H2、CO、CO2、CH4、C2H4、C2H6、C2H2）The analysis adopts a mature scheme of one-time injection, dual column parallel connection, and three detector detection. If further testing is requiredThe content of O2 and N2 can be configured with nine components.

The human-computer interaction interface of the 7-inch color touch screen is intuitive and easy to understand;

Full microcomputer computer anti control system，have6Road temperature control;8-channel external event time program;

Equipped with a dedicated workstation for analyzing dissolved gases in power transformer oil, it can integrate effective parts of multi-channel spectra for convenient spectrum processing. It can generate trend curves of the content of various gas components at the same sampling point over time, and automatically provide three ratio codes, fault characteristics, and typical examples in the report;

The instrument adoptsRJ45 Ethernet interface, simple and convenient signal output and control acquisition, can realize remote control of instruments and remote data transmission processing and supervision. Can be connected to unit supervisors and higher-level supervisors for easy supervision by supervisors;

Equipped with a dedicated independent balanced gas intake port, gas intake oscillation will not affect analysis.

Adopting transformer oil specific anti pollution composite chromatography column technology, the service life of the chromatography column is longer.

Large capacity column box with automatic rear door, can be operated8th order program temperature rise, column box near room temperature control function (5 ℃ above room temperature);

Equipped with fault self diagnosis function, displaying the location and nature of the fault at any time; Equipped with over temperature protection function, any temperature exceeding the set temperature will automatically stop heating.
