The gas detector is capable of on field detecting contents of SO2+SOF2, H2S, CO and HF in SF6 gas rapidly at the same time

 

JH3000-4 SF6 Electrical Equipment Decomposition Products Detector,gas analyzer, is capable of on field detecting contents of SO2+SOF2, H2S, CO and HF in SF6 gas rapidly at the same time, as well as accurately analyzing and determining inner faults of SF6 electrical equipment (including breakers, mutual inductors, transformers, GIS and casing, etc.) by the built-in expert system, then providing the scientific basis for status maintenance of the equipment. It is applicable for supervision of SF6 electrical equipments and quality inspection of SF6 gas in electricity, railway, metallurgy, petrochemicals and the industries manufacturing SF6 electrical equipments.

JH3000-4 instrument has the following functions:

1)  Multi-component detection, it can detect contents of SO2+SOF2, H2S, CO and HF, then provide more specific basis for fault diagnosis of equipments.

2)   Automatic decision for detection endpoint, which improves the accuracy of detection data.

3)   Auto-compensation of sensor for the temperature drift, which insures that the actual data can be obtained in various ambient temperatures.

4)   A built-in system design scheme is adopted. The built-in operation system can beautify the interface and provide a friendly man-computer interface in addition to improving the real-time performance and stability of the system .

5)   Protection function against excessive gas concentration, which prolongs the service life of sensor

6)   USB interface, which is convenient for data storage and transmission.
