GD8000C SF6 Gas Leakage Alarm Online Monitoring System General Information The quantitative leak alarm system is mainly used in the 35kV SF6 switch room and 110kV, 220kV and 500kV GIS room in the substation to monitor the SF6 gas leakage in the environment of the SF6 combined electrical equipment room and the oxygen content in the air in real time. When SF6 gas leaks, the density of SF6 gas is more than 5 times that of air, which accumulates in the lower space and causes local oxygen deficiency, causing major accidents. GD8000C SF6 Gas Leakage Alarm Online Monitoring System uses multiple sets of new high-sensitivity imported SF6-O2 sensors, temperature sensors and humidity sensors. When the indoor SF6 and O2 concentrations change slightly, the sensors can respond to these changes immediately, even if the SF6 concentration is 10ppmv can be effectively monitored. The concentration change monitored by the sensor is converted into a RS485 communication digital signal by the transmitter, A/D module, RS485 communication module and single-chip microcomputer, and the signal is sent to the main controller through the on-site RS485 bus, and the main controller performs data process and store, judge whether to alarm and remote communication.
