Operation and maintenance of sulfur hexafluoride gas 1, regular inspection, the staff on duty should use SF6 gas storage equipment to detect sulfur hexafluoride gas leak detector every day for detection, if the detected leakage content exceeds the standard and should report immediately, timely treatment. 2, patrol explosion-proof film. GIS equipment equipped with explosion-proof film should be inspected regularly every day, but should not stay near the explosion-proof film. Report any anom

Where does the moisture in the sulfur hexafluoride gas come from? In fact, in the process of SF6 gas production will be affected by the material of the production equipment, process conditions and other factors, in addition to the water generated in the synthesis process, in the gas filling process may also be mixed with a small amount of water. In order to prevent the possible harm of sulfur hexafluoride gas moisture, there are strict regulations for the quality indicators of SF6 gas, requiring

SF6 circuit breaker interrupter chamber structure according to the pressure of the interrupter medium is different, divided into double pressure type and single pressure type, but the double pressure type is generally not used because of the complex structure and auxiliary equipment. According to the direction of the blowing arc, it can be divided into double blowing, single blowing, external blowing and internal blowing. According to the direction of movement of the contact, it is divided into
