Description
The GSA-0/SO SF6 Gas Leak Online Monitoring System is a professional, 24/7 online safety monitoring solution designed for enclosed high-voltage environments such as SF6 switchgear rooms, GIS halls, and transformer compartments. It integrates real-time SF6 leakage detection and oxygen (O₂) deficiency monitoring to address the dual hazards of SF6 leakage (a potent greenhouse gas) and oxygen displacement (asphyxiation risk).
Adopting high-sensitivity NDIR infrared sensing for SF6 and electrochemical sensors for O₂, the system delivers rapid, stable, and interference-free monitoring. Fully compliant with IEC 60480, GB/T 8905, and DL/T 639, it supports real-time data display, multi-channel alarm, and automatic linkage with ventilation systems, providing comprehensive safety protection for personnel and equipment in power utilities, manufacturing, and industrial sites.

FAQ
Q: What standards does the GSA-0/SO comply with?
A: The system fully complies with IEC 60480, GB/T 8905, DL/T 639, and CE, meeting global SF6 safety and environmental protection requirements.
Q: Can it monitor both SF6 leakage and oxygen deficiency?
A: Yes. It simultaneously detects SF6 concentration and O₂ levels, providing early warning for both gas leakage and asphyxiation risks.
Q: Does it support automatic ventilation control?
A: Yes. It triggers external or built-in fans when alarms are activated to rapidly dilute SF6 and restore oxygen levels, ensuring on-site safety.
Q: How is the data stored and exported?
A: It supports up to 5 million historical records with timestamps and can export Excel/PDF reports via USB for compliance documentation and project handover.
Q: Is it suitable for outdoor substation environments?
A: Yes. It has an IP66-rated enclosure, explosion-proof design, and wide operating temperature range (-25°C~+70°C), making it suitable for harsh outdoor conditions.
Q: Can it integrate with existing SCADA systems?
A: Yes. It supports RS-485/Modbus-RTU, Ethernet, and IEC 61850 protocols, enabling seamless integration with SCADA, PLC, and cloud platforms for centralized monitoring.
Q: Warranty and after-sales support?
A: We provide a standard 1-year whole-machine warranty, lifetime technical support, on-site calibration, and maintenance services through our global service network. Extended warranty plans are available upon request.
