An alternative to Sulfr hexafluoride in electrical switchgear - EE Publishers

The ubiquitous insulation and switching medium, SF 6, a man-made gas developed in the early 20th century, is no exception to this trend. Due to its excellent properties for electric insulation and arc interruption, sf6 gas enables safe and reliable operations while making it possible to reduce the size of switchgear installations significantly.

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

In this issue, we discuss the use of sf 6 (sulfur hexafluoride) gas in medium-voltage switchgear. sf6 gas 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.

Fighting global warming using sf 6 alternatives and AI - Seetalabs

May 18, 2020 · The gas insulated switchgear (GIS) is a popular example of sf6 gas application due to its higher dielectric strength, density, and electronegativity as compared to air. The self-healing of insulating gas also promotes its use for arc-quenching purposes. However, Sulfr hexafluoride is a green house gas with global warming potential (GWP) 24000 times higher than carbon dioxide. The life-cycle management costs while handling sf 6-filled aged equipments is also high.

gaz sf6 circuit breaker maintenance | TD Guardian Articles

The industry was ready for an alternative to the traditional mediums of mineral oil and/or air. Using sf 6 as an interrupting medium had the advantages of being inflammable as well as having high dielectric strength and exceptional thermal stability. The first generation of Sulfr hexafluoride circuit breakers was the lower voltage classes of 72kV and 145kV.

Siemens to provide UK’s first insulating gas free 145kV vacuum circuit

The chemical properties of gaz sf6 gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear. However, it has a high global warming potential and contributes to the greenhouse effect if released to the atmosphere. Strict regulations are in place to manage sf 6 (F-gas) and there is pressure on the switchgear supply industry to provide sf6 gas gas alternatives to reduce the impact of any gas emissions caused by failures or handling.
