Sistem HZGC-1210 direka bentuk berdasarkan semua kelebihan pemantauan dalam talian kromatogram minyak di dalam dan luar negara. Jadi sistem ini mempunyai kelebihan yang jelas dalam aspek kestabilan, kebolehpercayaan dan ketepatan.

♦ On-line testing the concentration and growth rate of H2,CO,CO2,CH4,C2H4,C2H2,C2H6

♦ The method of quantitative cleaning and circulatory sampling could truly reflect the state of gas dissolved in oil.

♦ Oil-gas separation is safe and reliable without any pollution. The users could choose to discharge the transformer oil or not.

♦ It adopted dedicated composite chromatographic column to improve the degree of separation of gas component.

♦ It adopted imported detector to enhance the sensitivity of testing hydrocarbon gases.

♦ The gas detection technique has high stability and precision with ± 10 percent error range.

♦ Mature and reliable as the communication mode is, it adopted standard networking protocols and could support remote data transmission.

♦ Data collection, adopted the oversampling technology Δ - ∑ analog-digital converter with 24-bit resolution and automatic calibration, is highly reliable.

♦ Diverse data display and inquiry modes could provide report and trend chart. The storage life of historical data is 10 years.

♦ It has strong environmental adaptability, widely used in cold, hot, high humidity and high altitude areas.

♦ The performance of anti-interference is outstanding. The electromagnetic compatibility could meet GB/T17626 and IEC61000 standard.

♦ It offered 2 level of alarming set. Alerting signal could spread widely.

♦ Open database could access to LAN of electric system.

Selain itu, sistem HZGC-1210 menggunakan reka bentuk modular dengan aplikasi pemproses terbenam berprestasi tinggi, menjadikan sistem pemantauan dalam talian kromatografi lebih stabil dan boleh dipercayai. Ia mempunyai ciri-ciri berikut:

♦ It has faster analysis cycle which can be set by users themselves. The minimum monitoring cycle is 40 to 60 minutes. We recommend setting 24 hours as an inspection cycle;

♦ It takes only 10 minutes to separate oil and gas. It uses special environmental adaptation technology to eliminate any change of gas distribution coefficient caused by the temperature and humidity changes.

♦Analyzed oil sample adopted the technique of degassing and buffering, removing the mingled bubble in oil sample of reinjection transformer. The technique of multilayer isolated reinjection oiling (return oiling) could guarantee the carried gas would not be taken into the transformer.

♦ The minimum limit of detection of C2H2 can reach 0.1-0.5 μ L/L.

♦ It adopted double circuit and multi{{0}}mode thermostatic control with ± 0.1 degree temperature control accuracy. The device is equipped with industrial air conditioning which has the function of automatic constant temperature control.

♦ The embedded processor control system is multi-function, combining oil-gas separation, data acquisition, chromatographic analysis, concentration calculation, data alarming, and equipment condition monitoring. Cases like data loss would be avoided, greatly improving the reliability and stability of the system.

♦ Functional interface circuit adopted opto-isolator to further improve the ability of anti-interference.

♦ Via Ethernet, it could realize full-digital and remote data transmission, parameter setting and control.

♦ It improves the function of fault diagnosis, applying modified three ratio method, David trigonometry and cube graphic method to draw the diagnosis result;

♦ It strengthens self-inspection and adds the function of remote maintenance and alarming for equipment abnormality

♦ It supports 61850 communication protocol, providing networking for monitoring equipment of the same kind, so that it can realize concentrated remote diagnosis in a certain area.

♦ The system adopted 19 standard case and high-integrated modular design, which is easy to install and maintain with user-friendly operation.

♦ With wide expandability, it could integrate with other monitoring device conveniently.

♦ The design of non-cylinder saves the time and money to change the carrier gas every year so that after sale maintenance would be much easier. Without high pressure vessel nearby, transformers would be safer, free from any potential risk.
