Continuous SF6 gas monitoring system for high-voltage equipment. Real-time density, moisture & leak detection with ±0.75%FS accuracy. IEC 61850 compliant
SF6 Gas Leakage Alarm System — High-Precision Guardian for Electrical Safety
Product Overview
The SF6 Gas Leakage Alarm System is a robust safety monitoring solution designed for the power industry. Integrating SF6 gas leak detection, oxygen concentration monitoring, and intelligent alarm functions, it ensures real-time protection in critical environments such as substations and GIS switchrooms. Leveraging infrared absorption technology and digital compensation, this system delivers unmatched accuracy and reliability, enabling unmanned operation and smart grid compliance.
Key Features
�� Advanced Dual Gas Monitoring
· SF6 Detection: Utilizes dual-wavelength infrared sensors with temperature compensation for precise measurement (0–3000ppm ±1% FS error).
· O2 Monitoring: Detects oxygen levels (0–99%) with ≤0.5% error at 21% O2. Triggers alarms when O2 drops below 20%.
�� Multi-Stage Alarm & Fan Control
· Threshold Alarms: Audible/visual alerts and 24V/switch outputs activated when SF6 >1000ppm or O2 <18%.
· Smart Fan Control: Supports 5 daily time slots, motion-triggered activation, or manual override. Customizable ventilation duration (default: 15min/cycle).
�� Seamless System Integration
· Protocol Compatibility: RS485 with standard power protocols; optional IEC 61850 (IED module) for integration with SCADA systems (NARI, NR Electric, XJ Group, etc.).
· Real-Time Data Transmission: SF6/O2 levels, temperature/humidity, and device statuses are relayed to control centers for remote monitoring.
��️ Industrial-Grade Durability
· Extended Lifespan: Sensors rated for >10 years. Operates in extreme conditions: -40°C to +70°C, ≤99% RH, and seismic Zone 7.
· Robust Protection: IP66-rated enclosure, >10MΩ insulation, >2000V surge resistance, and EMI/lightning compliance (GB/T 17626 Level 3).
