General Information:
Transformer Oil Dissolved Gas Analyzer (also called: Transformer Oil Gas Chromatography Analyzer) uses chromatographic method to determine the content of dissolved gas in transformer oil. It is effective for power generation and power supply companies to determine whether there are latent overheating, discharge and other faults in oil-filled power equipment in operation to ensure safe and effective operation of the power grid. means. It is also a necessary means for manufacturers of oil-filled electrical equipment to carry out factory inspections of their equipment.
It is suitable for the determination of the content of the dissolved gas components in the insulating oil of the power system. The full analysis of the content of the 7 gas components dissolved in the insulating oil can be completed with one sample injection. The minimum detection concentration of acetylene is 0.01ppm, and the stabilization time is less than the baseline was stable at 40 minutes.
Composition of detection objects: H2, CO, CO2, CH4, C2H4, C2H6, C2H2.
Reference standard: IEC60599-2015, IEC60567-2011
Features:
- The control panel adopts a 7-inch color touch screen design with intuitive display, rich content and easy operation.
- The electronic gas circuit control system has higher and more precise control accuracy. It has multiple control modes such as constant current, constant pressure, program pressure and flow rate, which realizes the comprehensive digitization and intelligence of the instrument, and ensures the repeatability and accuracy of the analysis results. sex.
- The chromatographic process with three detector signals output at the same time has good separation effect and high sensitivity.
- Intelligent self-diagnosis function, the program can diagnose and protect the circuit itself. When the carrier gas leaks or loses gas, the bridge current will be automatically disconnected, which improves the reliability of the instrument.
- The instrument has intelligent operating procedures such as power-on self-check, automatic temperature rise, FID ignition and TCD plus bridge flow. After power-on, it can quickly reach a stable state and perform sample analysis without any operation.
- It can remotely operate the instrument, observe spectra, query data, and remotely calibrate through the network.
