SF6 Gas Leak Alarm System is a core safety monitoring device for power and industrial high-voltage electrical equipment. It is mainly used to detect SF6 gas concentration in real time, prevent leakage risks, and ensure the safety of personnel and equipment. It is widely used in substations, power distribution rooms, GIS rooms, switch rooms and other places.

I. Core Safety Functions

1. Real-time leakage monitoring and early risk warningContinuously detect the concentration of SF6 gas and oxygen in the environment. Data will be captured immediately in case of micro leakage to prevent leakage from expanding and causing safety accidents.
2. Prevent hypoxia and suffocation to protect personal safetySF6 gas is denser than air and will accumulate at low levels to displace oxygen. The system monitors oxygen content synchronously and alarms immediately when it is below the safe value, preventing suffocation when personnel enter a hypoxic environment.
3. Avoid poisoning and health hazardsSF6 decomposes into toxic and corrosive gases under high-temperature electric arcs. The system can quickly detect abnormalities to avoid health risks such as respiratory tract injury and poisoning caused by inhalation.
4. Interlock ventilation to automatically eliminate hidden dangersThe system can automatically start the ventilator upon detecting leakage to forcibly discharge toxic gases and replenish fresh air, reducing risks quickly without manual intervention.

II. Equipment and Operation & Maintenance Support Functions

1. Ensure stable operation of electrical equipmentSF6 acts as the insulation and arc-extinguishing medium for high-voltage equipment. Leakage will lead to reduced insulation, tripping or even explosion of equipment. The alarm system enables early detection and treatment to maintain normal operation.
2. Comply with safety specifications and meet acceptance requirementsIt meets safety standards of the power industry and fire acceptance requirements, and is an essential safety protection device for power distribution rooms, GIS rooms and other places.
3. Reduce operation and maintenance costs and minimize accident lossesEarly warning avoids major equipment damage, casualties and production downtime, greatly reducing post-accident maintenance and emergency disposal costs.

III. Practical Application Value

1. 24-hour unattended monitoring replaces manual inspection, improving safety and efficiency.
2. Dual sound and light alarm provides clear reminders even in long-distance and noisy environments.
3. Data can be uploaded to the background for remote monitoring and historical traceability.
