SF6 gas concentration online monitoring and alarm system
J CD L/1 SF 6 gas concentration online monitoring and alarm system (hereinafter referred to as this system) is a high-tech new high-tech developed by our company for the personal protection needs of indoor staff in SF 6 switch room, combined electrical appliance (GIS) room, etc. product. This system adopts original imported sensors, combined with the powerful control capability of C P U, can monitor the concentration of SF 6 gas, oxygen content and ambient temperature and humidity online in real time, and use the bus for digital transmission of the measurement results. It can accurately and timely grasp the status of the operating equipment, and also control the exhaust air of the fan.
