I. A brief product introduction:
This intelligent online sf6 gas monitoring system enhances personnel safety in distribution rooms with SF6 equipment. It monitors ambient SF6 and oxygen levels in real time, detecting SF6 as low as 50 ppm. When SF6 exceeds 1000 ppm or oxygen falls below 18%, the system triggers audible/visual alarms and automatically starts fans to reduce SF6 concentration. With optional remote upload, real-time data and alarms can be sent to the control room, ensuring reliable personal safety protection in SF6 switchgear rooms.

VIII. Real-world Case Studies
The expansion and upgrade project of the power grid system in Dhaka, Bangladesh has been officially put into operation. The project has established an online monitoring network for SF ₆ gas concentration covering key areas, achieving early detection and automatic warning of leaks. The system integrates advanced sensing and data platforms, enhancing the intelligence level of environmental safety management, effectively preventing oxygen deficiency and equipment failure risks caused by gas accumulation, and providing reliable technical support for ensuring personnel safety, equipment stability, and fulfilling environmental responsibilities.
IX. Application Scenarios
• Underground substations: Poor ventilation makes SF6 leaks prone to accumulating in low-lying areas such as cable layers and maintenance access routes, leading to oxygen deficiency and suffocation risks.
• GIS equipment within tunnels (e.g., urban subway power supply systems).
• Any electrical equipment room with entrances below ground level or poor ventilation.
• Intelligent operation and maintenance of unattended and high-value assets.

XIV. FAQ
Q1: What is SF6 gas used for in GIS?
A1: It provides electrical insulation and rapidly extinguishes arcs.
Q2: Why must SF6 leaks be strictly controlled?
A2: Leaks impair insulation, cause failures, and SF6 is a potent greenhouse gas with major environmental and safety risks.
Q3: What are the key national standards for SF6 leakage?
A3: The annual leak rate must be ≤0.5%. Indoor installations require monitors and automatic ventilation if SF6 >1000μL/L or oxygen<18%.
Q4: What is the correct leak response process?
A4: Warn and ventilate → locate the leak → power down and repair → recover gas, vacuum, refill, and verify the seal.
