Profile:

  • The KDXJ-8 is a distributed SF6 gas leak alarm system designed for power substation safety. It quantitatively measures SF6 concentration (0~1000ppm), O₂ level, and ambient temperature, with customizable alarm thresholds. When SF6 exceeds limits or O₂ drops below safe levels, it automatically activates ventilation and triggers audible/visual alarms. The system supports wall-mounted installation, back-end monitoring, and data logging for up to 255 collection points, making it ideal for continuous safety monitoring in high-voltage equipment rooms.

Features:

  • Quantitative measurement of SF6, O₂, and temperature with high accuracy.
  • Customizable alarm thresholds for SF6 and O₂ concentrations.
  • Automatic ventilation and alarm activation when gas limits are breached.
  • Back-end monitoring and historical data storage for safety analysis.
  • Distributed architecture supporting up to 255 collection points.
  • Wall-mounted design for flexible installation in equipment rooms.
  • Manual ventilation control for emergency operation.
  • Human body induction interface for intuitive local operation.
  • High reliability with stable performance in harsh environmental conditions.
