details
GC-9280 typeTransformer oil dedicated gas chromatographThe determination of dissolved gas content in insulating oil by gas chromatography is an effective means for power generation and supply enterprises to determine whether there are latent overheating, discharge and other faults in oil filled power equipment during operation, in order to ensure the safe and effective operation of the power grid. It is also a necessary means for oil filled electrical equipment manufacturers to conduct factory inspections of their equipment.
GC-9280 typeTransformer oil dedicated gas chromatographIt is a multifunctional gas chromatograph developed based on the actual needs of the power system, which can measure both the dissolved gas content in insulation oil and the gas content in oil. It can meet the needs of multi task measurement and analysis of transformer oil in power systems. The system adopts a three detector process of one injection, dual column parallel connection, and one diversion, equipped withTCD detector, dual FID detector, and methane converter, where H2andO2pass throughTCD detection; Hydrocarbon gases (methane, ethylene, ethane, acetylene) pass through FID1testing,CO、CO2After being converted by a methane converterFID2Testing has overcome a lot of challengesCO、CO2The impact on hydrocarbon gases, especially acetylene. When analyzing, it is not necessary to change the chromatographic column and gas path flow to measure the oil contentThere are nine components: H2, O2, N2, CO, CO2, CH4, C2H4, C2H6, and C2H2.
Execution standards:
GB/T 17623-1998 "Determination of dissolved gas components in insulating oil by gas chromatography"
GB/T 7252-2001 "Guidelines for Analysis and Determination of Dissolved Gases in Transformer Oil"
DL/T 722-2000 "Guidelines for Analysis and Determination of Dissolved Gases in Transformer Oil"
instrumentcharacteristic:
Injection port flow rate, chromatographic column carrier gas flow rate, detector gas flow rate, precision control
Multiple injection ports can be configured: packed column injection port (with spacer blowing, can be connected to large-diameter capillary column), splitter/Non split capillary injection port, program-controlled cold column head injection port, volatile component series connection injection port (specially equipped with sample pretreatment devices such as headspace/sweep capture/thermal desorption);
Industry detector design
The amplification plate with special ceramic treatment is stable during humid seasons, automatically ignites, and has automatic protection against hydrogen leakage, making it safe and reliable.
Precise control program temperature rise and furnace temperature, precise furnace temperature tracking design
The internal control accuracy of the furnace is less than0.01℃； The temperature difference between internal points shall not exceed 1 ℃; Rapid heating and cooling,*Program heating speed120℃/min； Balance time of 10 seconds; Cooling time (300 ℃ to 50 ℃) for 6 minutes; Absolute temperature control accuracy (with a difference of less than 0.3 ℃ from the actual temperature).
Fully imported valve configuration system
*More equipped8 valves (four-way valve, six way valve, ten way valve, and liquid injection valve optional); Automatic control and sequential operation; 0 leakage blowing technology; High speed switching solenoid valve has a long service life (1 million times, 10mS).
Separated columns oven
In a multi column chromatography system, different column operating temperatures can be set separately to achieve separation efficiency for each column;
Convenient implementation of pneumatic cutting technology
It can achieve multidimensional chromatography function to separate and analyze complex samples, and can realize the blowback function of the chromatography column to greatly save analysis time and cycle;
The column box has a large volume, and the intelligent rear door opening system allows for infinitely variable air flow in and out, shortening the system's stable equilibrium time after program temperature rise/fall; Heating furnace system:The ambient temperature ranges from 7 ℃ to 400 ℃ Step program heating, heating rate 0-50 ℃/min; The increment of 0.1 ℃/min allows users to recalibrate the furnace temperature and freely set the highest temperature. The temperature equilibrium time of the heating furnace is determined by the user.
