gaz sf6 gas in medium-voltage switchgear | TD Guardian Articles

May 01, 2013 · In this issue, we discuss the use of insulating gas (sulfur hexafluoride) gas in medium-voltage switchgear. Sulfr hexafluoride has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses gaz sf6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.Get price

Fighting global warming using Sulfr hexafluoride alternatives and AI - Seetalabs

How Is Sulfr hexafluoride Related to Global Warming?How Artificial Intelligence Can Help?New FrontiersSulphur hexafluoride (sf 6), developed in early 20th century, is an inorganic, non-toxic, and stable gas that has many electro-technical applications. The gas insulated switchgear (GIS) is a popular example of Sulfr hexafluoride application due to its higher dielectric strength, density, and electronegativity as compared to air. The self-healing of sf 6 also promotes its use for arc-quenching purposes. However, sf 6 is a green house gas with global warming potential (GWP) 24000times higher than carbon dioxide. The life-cycle management costs while handling sf 6-filled aged equipments is also high. It will rise further with energy demands and need for gas-filled medium and high voltage switchgears. Therefore, power sector is working feverishly on eco-friendly gaz sf6 alternatives for application in electrical industry. Their primary concern is to retain the insulation efficiency and partial discharge resistance of Sulfr hexafluoride in the alternate gases, particularly for GIS.Get price
