To Research on Application and Maintenance of Sulfur Hexafluoride (SF6) Circuit Breaker

Analysis of Electric Field and Polarization of SF6 Circuit Breaker to Approach a Suitable Structure

Abstract: The application of electric field theory to widely different aspects of electrical insulation has led to more understanding the phenomena. Electric fields may be considered as the main reason for insulation failure. The purpose of this paper is to modify importance of analyzing electric field in insulation design. The SF6 circuit breaker is chosen as case study that encounters cri...

A Life Cycle Impact Assessment Study on Sulfur Hexafluoride (SF6) as a Gas Insulator

A lifecycle environmental impact analysis was conducted for SF6 used as an insulating gas in electrical devices. Eight scenarios with different forms of usage as an insulating gas (pure SF6 and gaseous mixture of SF6 with nitrogen) and treatment processes of waste SF6 (e.g., reproduction after decomposition, reuse after purification) are assumed. Energy consumption and emission of pollutants an...

Low-energy electron collisions with sulfur hexafluoride, SF6 C. Winstead and V. McKoy

We report calculated cross sections for elastic and electronically inelastic collisions of low-energy electrons with sulfur hexafluoride, SF6 . Elastic cross sections are computed within the fixed-nuclei approximation, with polarization effects incorporated. Inelastic cross sections for nine low-lying states are computed in a few-channel approximation. We compare our cross sections to previous ...

Correlation for the Viscosity of Sulfur Hexafluoride (SF6) from the Triple Point to 1000 K and Pressures to 50 MPa

Treatment of Symptomatic Vitreomacular Adhesion with Expansile Sulfur Hexafluoride (SF6) Gas

BACKGROUND To evaluate intravitreal injection of expansile sulfur hexafluoride (SF6) as a low cost and effective treatment for symptomatic vitreomacular adhesion (sVMA). METHODS Retrospective analysis of all patients with sVMA treated with pneumatic vitreolysis using SF6 gas presenting to a clinical practice from January 2005 and June 2013. RESULTS Six cases were included in the study. Five...
