  • The SF6 Decomposition Mechanism: Background and

    2017-1-24Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition phenomenon would greatly reduce the

  • SF6 Gas Decomposition discount -

    A ppb-level photoacoustic multicomponent gas sensor system for sulfur hexafluoride (SF6) decomposition detection was developed by the use of two near-infrared (NIR) diode lasers and an ultraviolet (UV) solid-state laser. A telecommunication fiber amplifier module was used to boost up the excitation optical power from the two NIR lasers.

  • Application of flower-like ZnO nanorods Gas sensor

    Detecting and analyzing the decomposition byproducts of sulfur hexafluoride gas (SF 6) is an effectivemethod for GIS state assessment and fault diagnosis. This paper proposes a novel gas sensor based on flower-like ZnO nanorods to detect typical SF 6 decompositions. Flower-like ZnO nanoparticles were synthesized via a simple hydrothermalmethod

  • Tellurene Nanoflake-Based Gas Sensors for the Detection of

    2021-2-24Tellurene has a phosphorene-like puckered configuration and exhibits great air stability. This characteristic makes it highly sensitive to some gases, and therefore, it has a huge potential in gas sensing applications. In this paper, the sensing performance of tellurene-based gas sensors toward SF6 decomposition products, including H2S, SO2, SO2F2, and SOF2, was systematically investigated
