Research progress on photoacoustic SF6 decomposition gas sensor in gas-insulated switchgear
Journal of Applied Physics, 2022 In the power industry, sulfur hexafluoride (SF6) as an insulating gas is widely used in gas-insulated switchgears (GISs). Owing to the latent inner insulation defects of GIS, various SF6 gas decompositions are generated in the process of partial ...

Compact QEPAS humidity sensor in SF6 buffer gas for high-voltage gas power systems
Photoacoustics, 2021 In SF6 insulated high-voltage gas power systems, H2O is the most problematic impurity which not only decreases insulation performance but also creates an acidic atmosphere that promotes corrosion. Corrosion damages electrical equipment and leads to leaks,

Breakdown Gradients in SF6-N2, SF6-Air and SF6-CO2 Mixtures
IEEE Transactions on Electrical Insulation, 1980 A method to calculate the uniform field breakdown gradients for SF6-N2, SF6-air and SF6-CO2 mixtures is discussed. Calculated values of the breakdown gradients in these mixtures are compared with experimentally measured values using plane-plane electrode configuration and direct applied voltages.

Host Range Expansion of Shigella Phage Sf6 Evolves through Point Mutations in the Tailspike
Journal of Virology, 2022 Viruses depend on host cells to propagate themselves. In mixed populations and communities of host cells, finding these susceptible host cells may have to be balanced with avoiding nonhost cells.

High-resolution cryo-EM structure of the Shigella virus Sf6 genome delivery tail machine
Science Advances, 2022 Sf6 is a bacterial virus that infects the human pathogen Shigella flexneri. Here, we describe the cryo–electron microscopy structure of the Sf6 tail machine before DNA ejection, which we determined at a 2.7-angstrom resolution.

Improving measurements of SF6 for the study of atmospheric transport and emissions [PDF]
, 2011 Sulfur hexafluoride (SF6) is a potent greenhouse gas and useful atmospheric tracer. Measurements of SF6 on global and regional scales are necessary to estimate emissions and to verify or examine the performance of atmospheric transport models.

Recent Development of Two Alternative Gases to SF6 for High Voltage Electrical Power Applications
Energies, 2021 For many years, SF6 has been the preferred dielectric medium in electrical power applications, particularly in high voltage gas-insulated equipment. However, with the recognition that SF6 has an extremely long atmospheric lifetime and very high global ...

Research on Environmental Protection Treatment for Ex-Service SF6 Adsorbent
IEEE Access, 2020 SF6 adsorbents absorb many toxic SF6 decomposition products, such as SOF2, SO2F2, and H2S. Ex-service SF6 adsorbents that did not undergo environmentally friendly processing will seriously harm the environment.
