GCBJ-H SF6 Gas Leakage Quantitative Alarm System Introduction: The laser method SF6 gas leakage intelligent monitoring and alarm system is an intelligent online monitoring system designed and developed in accordance with the SF6 Safety Regulations to provide personal health and safety protection for workers in distribution equipment rooms equipped with SF6 equipment. It mainly detects the concentration and oxygen content of SF6 gas in the switchgear room. When the SF6 gas content in the environment exceeds the standard or lacks oxygen, it can give a real-time alarm and automatically turn on the ventilation fan for ventilation. It also has many rich functions such as temperature and humidity detection, voice prompt of working status, remote alarm, and historical data query. Its unique infrared detection technology for trace SF6 gas can detect SF6 gas with a concentration of 10-5000ppm, which not only ensures personal safety but also ensures the normal operation of the equipment; Imported highly stable oxygen sensors can provide more reliable protection for on-site workers. This system can be widely used in various voltage levels of SF6 switchgear rooms, SF6 switchgear rooms, combined electrical rooms (GIS rooms), SF6 main transformer rooms, etc. Features: 1. Laser detection of SF6 gas content in the environment; 2. Automatically start the exhaust function of the fan when there is an over limit alarm leakage; 3. O2 content detection function in the environment; Automatic alarm and exhaust when lacking oxygen; 4. Large screen LCD dynamic Chinese display with automatic screen protection function. Friendly interface, fast refresh speed; 5. When the SF6 and O2 gas content exceeds the standard, the fan will automatically start the function; 6. Regular exhaust function; 7. Activate the forced ventilation function when an alarm is triggered; 8. Relevant historical data storage and retrieval functions; 9. Temperature and humidity detection, alarm and display; 10. Infrared detection, voice prompt alarm function; Technical parameters: SF6 concentration exceeding limit alarm point: 1000ppm, accuracy < ± 1%; O2 concentration detection range: 0-25%, O2 deficiency alarm point: 18%, accuracy<0.5%; Temperature display range: -20~+99 ℃, humidity display range: 0~99% RH; Input power supply: AC 220V ± 20%; Alarm output contact power: AC220/7A; Fan output contact: 380V/15A (three-phase) or 220V/15A; Fan start: When the O2 content is ≤ 19.6% or the SF6 gas concentration is>1000ppm, the fan will be automatically started, and the start time will be automatically set according to the time period. The fan can be manually controlled or forced to start; SF6 gas detection alarm error:<1%, Oxygen alarm error: < 0.5%;
