The KDFJ-II SF6 gas comprehensive analyzer integrates SF6 micro water analyzer, SF6 purity analyzer, and SF6 decomposition product analyzer, consolidating functions that originally required three instruments into one instrument. One on-site measurement can complete the detection of three indicators, greatly saving gas in the equipment. One measurement saves 2/3 of gas usage, while reducing the workload of users and improving work efficiency.

The faults of SF6 electrical equipment are divided into internal faults of the body and faults of the operating mechanism; Internal faults involving solid insulation pose the greatest threat to equipment safety, and can be divided into two categories: discharge and overheating. Discharge type faults are further divided into floating potential discharge, ground discharge, and inter turn discharge.

At present, commonly used electrical tests both domestically and internationally are usually conducted during power outages, and the detection rate for insulation that poses the greatest threat to safety is very low. The KDFJ-II SF6 gas comprehensive analyzer is intelligent, with high sensitivity, stability, and easy operation. It can automatically diagnose and provide treatment suggestions based on the detected concentration, providing a simple and effective efficiency for early detection of internal faults in SF6 electrical equipment.

1. Fast gas saving: After starting up and entering the measurement state, the measurement time for SF6 gas dew point is about 5 minutes, and the measurement time for SF6 decomposition products is about 2 minutes.

2. Self locking connector: Using German imported self-locking connectors, it is safe, reliable, and leak free.

3. Data storage: Designed with a large capacity, it can store up to 200 sets of test data.

4. Curve function: The large screen curve displays the dew point measurement process.

5. Clear display: The LCD screen directly displays dew point, micro water (ppm), SO2+SOF2, H2S, CO content, environmental temperature, environmental humidity, time, and date.

6. Built in power supply: Equipped with a 4Ah rechargeable lithium battery, it can work continuously for 10 hours when fully charged.

7. Monitor SO2, H2S, and CO decomposition products simultaneously.

8. Able to quickly detect and diagnose internal faults of SF6 electrical equipment (circuit breakers, transformers, GIS, and bushings, etc.) on site.

9. This instrument can be widely used for SF6 electrical equipment in the power, railway, metallurgical, and petrochemical industries.
