Introduction:

● Separation and determination of dissolved gases in insulating oil group by gas chromatography is the power supply enterprise to judge the oil filled power equipment in the operation of the existence of potential overheating, discharge of the fault, in order to ensure the effective operation of the power grid safety. Oil filled electrical equipment manufacturers is the necessary means for the factory inspection of the equipment.     

● Our company is a special transformer oil chromatograph launched a dedicated power special insulating gas oil dissolved gas component content determination of chromatograph instrument adopts advanced process with three detector, TCD detector and two FID detector, one injection, 7 minutes to complete the analysis of 7 kinds of gases dissolved in insulating oil the component content. The H2 was detected by TCD; hydrocarbon gases (CH4, C2H4, C2H6, C2H2) was detected by FID1, CO, CO2 by FID2 detection, to overcome the influence of a large number of CO and CO2 on hydrocarbon gas, especially the effect of C2H2, shorten the detection time and improve detection sensitivity.

Technical Specifications:

The main technical index is ul/L (ppm):

H₂< 2,CO＜2，CO₂＜2，CH₄ ＜0.1，C₂H₄＜0.1，C₂H₆＜0.1，C₂H₂＜0.1

Implementation standards:

Characteristics:

1 :  To achieve real-time computer control and data processing:

Instrument with digital interface, realize real-time data signal acquisition, data processing and test results on the computer through a communication line. Instruments and computers connected to the Internet can be connected by remote computers and instruments to realize remote data acquisition and management. The degree of freedom of the device is improved, and the effective application of the laboratory is promoted.

Through humanized software interface, greatly facilitate the user set including various temperature; intuitive operation including FID (first ignition has been changed fully automatically, without manual operation), open and close the switch bridge flow, temperature control, and each time events etc.;

2:  High precision, stable and reliable temperature control system:

Main control circuit adopts the advanced microprocessor, large memory, the data storage is more reliable; the integration of measurement, control, and design of circuit board improves the anti-interference and reliability of the instrument; the temperature control circuit of the microprocessor, the heating zone temperature controlled object accuracy reached 0.1 degree;

The column case has over temperature protection. Any way the temperature exceeds the set extremely difficult, the instrument will stop heating, and on the display to report the location of the fault;
