SF6 gas mass is heavier than air, in the case of not fully mixed with air, SF6 gas has a tendency to deposit in low places, such as cable trench, indoor bottom, the bottom of the container, etc. In these places where there may be a large amount of SF6 gas deposits, it is easy to be hypoxic, and there is a danger of suffocation. Therefore, most regulations stipulate that the maximum allowable concentration of SF6 gas in the workplace for operation and maintenance is 1000UL/L.

Indoor installation of SF6 electrical equipment, its installation and the main control room should be air-tight isolation, to prevent the spread of toxic gases into the main control room, SF6 leakage monitoring system should be installed at the entrance of SF6 electrical equipment, the detection of SF6 and oxygen, the air oxygen content should be greater than 18%, the concentration of SF6 in the ambient air should not exceed 1000UL/L.

(1) The harm of SF6 gas. For a long time, due to the use and poor management of SF6 gas, many toxic, corrosive gases and solid decomposition are discharged into the atmosphere, causing irreparable pollution and damage to the environment we rely on for survival, and endangering the normal operation of electrical equipment and human health;
