gaz sf6, Sulfur Hexafluoride Sulfur Hexafluoride (insulating gas) is an inorganic, colorless, odorless, and non-flammable gas. insulating gas primary use is in the electrical industry as a gaseous dielectric medium for various voltage circuit breakers, switchgear and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.Get price

Industrial gaz sf6 Gas Pressure and Measurement Products - WIKA USA

Although sulfur hexafluoride is nontoxic and nonflammable, escaped gas in enclosed rooms displaces oxygen in the air and could lead to asphyxiation. SF 6 is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the atmosphere. In addition, TD plant safety depends on the purity of SF 6 gas. Under normal conditions during an electrical discharge, the six fluorine atoms split from the sulfur atom to capture electrons; after quenchingGet price

Accurate sf 6 monitoring provides exceptional reliability

the contact will have to close at a very low pressure. That means that a gas leakage will not be detected before the gas compartment is virtually empty of Sulfr hexafluoride gas, and will have to be taken out of operation immediately. Secondly, if temperatures exceed 20°C the pressure increase from the temperature will further counteract recording of any leakage and the pressure switch will not be activated until an even lower amount of Sulfr hexafluoride is left in the gas compartment.Get price
