Before the use of sulfur hexafluoride gas, we first understand the basic properties of SF6 gas. SF6 gas has a history of more than 100 years, it was synthesized by two French chemists, Moissan and Lebeau, in 1900, and made commercially available in 1947. Sulfur hexafluoride is a volatile compound. Yellow-brown at room temperature, reddish brown in liquid and gas. Strong alpha radioactivity. Melting point 50.75℃. Boiling point 62.3℃. It does not sublimate at atmospheric pressure, but unlike urani

If the purity of sulfur hexafluoride gas is low, its insulation strength will be greatly reduced, and it is easy to be broken down by high voltage when used in electrical insulation, resulting in accidents from the test and research results of relevant departments. So what are the reasons for the impurity of sulfur hexafluoride gas?

SF6 gas is a colorless, odorless, odorless, non-toxic, inert gas that is denser than air and is one of the six greenhouse gases discovered today. SF6 gas is widely used in the high voltage electrical appliance manufacturing industry. Pure sulfur hexafluoride gas is a non-toxic and harmless asphyxiating gas, and there is no toxic sulfur hexafluoride. However, the impure SF6 gas is very harmful to the environment and the human body and equipment. Especially when sulfur hexafluoride gas co

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 is mainly composed of working cylinder, main voltage reservoir, arc extinguishing chamber, voltage equalizing capacitor, triple header, pillar, connecting seat, density relay, oil supply and discharge valve and auxiliary fuel tank, which is a closed combination electrical appliance. SF6 gas mainly plays the role of insulation, arc extinguishing and heat dissipation, chemical properties are very stable, is a colorless, odorless, non-toxic, will not burn gas. The action proces
