• Power Industry: Suitable for substations, distribution rooms, and similar facilities, detecting gas leaks in power equipment such as sulfur hexafluoride circuit breakers and GIS (Gas Insulated Switchgear). Ensures stable insulation and arc-quenching performance of power systems, preventing equipment failures that could cause power outages.
• Electrical Equipment Manufacturing/Maintenance: During production assembly, factory testing, and field maintenance of SF₆-related electrical equipment (e.g., instrument transformers, surge arresters), it identifies leaks caused by seal aging or loose connections, ensuring product quality and post-maintenance equipment integrity.
• Chemical and Industrial Production: For chemical production lines, industrial furnaces, and other scenarios using SF₆ as an insulating medium, etching gas, or protective gas, it enables real-time monitoring of gas leaks to prevent safety risks (such as oxygen deficiency or explosion hazards) and environmental impacts caused by gas leaks.
• Laboratories and Research Institutions: Used for leak testing of experimental apparatus and piping systems involving sulfur hexafluoride gas. This ensures controlled and safe experimental processes, preventing gas leaks that could compromise data accuracy or cause laboratory environmental contamination.
• Construction and Refrigeration: Used in leak detection during installation and operation of specialized refrigeration equipment and thermal insulation sealing systems employing SF₆. Ensures optimal refrigeration/sealing performance while preventing efficiency loss or safety hazards from gas leaks.
• Emergency Detection Scenarios: At emergency response sites where SF₆ gas leaks are suspected, the device can be rapidly deployed for on-site qualitative detection to locate leak sources. This provides decision-making support for emergency rescue and personnel evacuation, minimizing hazards to personnel and the environment from leaked gas.
• Note: Ensure the device operates within its environmental specifications (0°C to 50°C, 0% RH to 80% RH non-condensing). Avoid use in harsh conditions such as high concentrations of corrosive gases, severe vibration, or strong electromagnetic fields to maintain detection accuracy and device stability.
