Transformer Oil Dissolved Gas Analyzer Chromatography Analyzer for Transformer Oil Gas Analysis
Overview of transformer oil dissolved gas analyzer
GC-7890A-DL Gas Chromatograph for Transformer Oil (Insulating Oil) Analysis is a multi-functional gas chromatograph specially designed for the analysis of dissolved gas content in insulating oil. The instrument adopts the advanced dual-column parallel connection, tandem thermal conductivity detector, methane conversion furnace, double hydrogen flame detector gas flow, can be a sample to complete the dissolved H2, O2, N2, CO, CO2, CH4, C2H4, C2H6, C2H2 nine kinds of gases in the insulating oil components of the analysis of the whole. Powerful functions, excellent performance, good separation effect, sensitivity and other characteristics, can fully meet the needs of multi-task detection and analysis of insulating oil, all performance indicators are better than the national standard, is the first choice for users of insulating oil analysis.
Performance Characteristics of transformer oil dissolved gas analyzer
- large LCD blue screen, Chinese and English display.
- It can monitor various parameters such as temperature and flow rate in real time, and the heating power will be cut off automatically after the heating area is over-temperature.
- With gas cut protection function. When the carrier gas pressure is lower than 0.1MPa, the instrument will automatically alarm and cut off the heating power supply, thermal conductivity bridge current.
- With parameter storage function. After power failure and restoration of power supply, the instrument will automatically return to the operating state before power failure.
- With fault self-diagnosis function. The instrument detects each operating parameter in real time, and the microcomputer system will protect the instrument automatically when there is abnormality.
- With automatic ignition function.
- The gas circuit system adopts a unique pressure stabilization process design, reducing the impact of pressure fluctuations on the detector during gas injection, thus minimizing the impact of the impact of the peak on the analysis to ensure that the analysis results of the high reproducibility and high accuracy.
- The whole machine has changed the traditional three-box design and adopted the advanced two-box design. The built-in gas circuit system makes the appearance of the instrument more neat and beautiful, and improves the safety of instrument operation.
- Carrier gas, hydrogen and air are indicated by pressure gauges, which makes the operator know the conditions of chromatographic analysis at a glance and is easy to operate.
- The main and key components are imported components, extend the service life of the machine, reduce maintenance costs.
- The inlet, detector, conversion furnace are modular design, easy to disassemble, without any experience in chromatography can be easily disassembled and replaced.
- Large column box (291 * 284 * 260mm, 21.5L), so that it is more convenient to disassemble the column.
