In order to prevent the lack of oxygen caused by the retention of SF6 gas in the equipment room due to leakage, or the existence of trace harmful substances to endanger the health of personnel, SF6 and oxygen content should be tested regularly. The oxygen content of the air should be greater than 18%.
For indoor SF6 electrical equipment places frequented by staff, air exchange should be at least 15min per shift, and the volume of air exchange should be 3 to 5 times the space volume; The air outlet should be placed in the lower part of the room; For equipment places that are not frequently accessed by staff, ventilation should be carried out for 15min before entering.
In the indoor SF6 electrical equipment installation site on the ground floor, the alarm device oxygen meter and SF6 leakage alarm meter should be installed. The oxygen meter should give an alarm when the oxygen content in the air drops to 18%; The SF6 leak alarm alarms when the SF6 level in the air reaches 1000μL/L. If found unqualified, should be ventilated, ventilation.
