Product Description

Brief introduction

Transformer oil chromatograph (Transformer Oil Dissolved Gas Analyzer) is used to determine the component content of dissolved gas in transformer oil by chromatography. It is an effective means for power generation and power supply enterprises to judge whether there are latent overheating, discharge and other faults in oil filled power equipment in operation, so as to ensure the safe and effective operation of power grid. It is also a necessary means for oil filled electrical equipment manufacturers to carry out factory inspection on their equipment.

It is suitable for the determination of dissolved gas components in insulating oil of power system. The total analysis of seven dissolved gas components in insulating oil can be completed with one sample injection. The minimum detection concentration of acetylene is 0.05ppm, the stable time is less than 40 minutes, and the baseline is stable.

Main detection: H2, Co, CO2, CH4, C2H4, C2H6, C2H2

Instrument features
 
1.The configuration scheme of special gas chromatograph for insulation is equipped with double FID detector, TCD detector, nickel conversion furnace, packed column sampler and three special chromatographic columns for insulating oil. The analysis results can be obtained by one injection of seven gases in insulating oil: carbon monoxide, carbon dioxide, methane, ethane, acetylene, ethylene and hydrogen.
 
2.New production process, redesigning the air source channel and internal structure in the instrument, making the layout of parts more reasonable, reducing signal interference of components, improving detection accuracy, and excellent stability and durability of the equipment.
 
3.It adopts 7-inch color touch screen control and professional chromatograph UI operation interface design, which can directly reflect the internal temperature value of injection port, column temperature box and detector, and the values of each detector, as well as the running time. It has the function of one key cooling. The user can set the detection conditions by himself, which is convenient for use.
 
4.The instrument has excellent repeatability. The repeatability error of the instrument can reach 2% under the experimental conditions of using automatic sampler, which is better than 3% of the national standard.
 
5.The column temperature box adopts six independent temperature control system, automatic back door opening system, 30 stage 31 platform temperature programmed, fast rising / cooling speed, and temperature control accuracy of 0.1 ºC, which makes the equipment competent for large-scale sample analysis.
 
6.It can be directly connected with the computer, and can be operated by PC terminal network edition chromatography workstation software (maximum support 253 sets), and realize the temperature rising and cooling of instrument injection port, column temperature box and detector by program control. Under the condition that the customer is equipped with an automatic injection valve (or an automatic injector), it can realize some test procedures such as unattended instrument, automatic temperature rising and ignition, automatic loading method, automatic calculation of test results, etc., meeting the requirements of online test.
 
7.Exclusive Internet of things chromatograph technology, built-in IP protocol stack, can upload test data to the computer of field laboratory, department head and superior leader through enterprise LAN or Internet, so as to facilitate each department to monitor the operation and test results of the instrument in real time. It can connect with manufacturers directly through the Internet to realize remote diagnosis and remote program update of gas chromatograph.
