Intelligent Monitoring and Alarm System for SF6 Gas Leakage

The 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.SF6 gas leakage alarm deviceThe main function is to detect the concentration and oxygen content of SF6 gas in the switch room. When the SF6 gas content in the environment exceeds the standard or there is oxygen deficiency, an alarm can be triggered in real time, and the ventilation fan can be automatically turned on for ventilation. It also has many rich functions such as temperature and humidity detection, working status voice prompt, remote alarm, and historical data query. He has a trace SF6 gas detection technology that can detect SF6 gas with a concentration of 10-5000ppm, which not only ensures personal safety but also ensures the normal operation of equipment; Imported highly stable oxygen sensors can provide more reliable protection for on-site workers.

This system can be widely used in SF6 switch rooms, SF6 switch rooms, combination electrical rooms (GIS rooms), SF6 main transformer rooms, etc. of various voltage levels.
