Pore-Structure Control in Metal-Organic Frameworks (MOFs) for Capture of the Greenhouse Gas SF6 with Record Separation.

Angewandte Chemie, 2022
In the electronics industry, the efficient recovery and capture of sulfur hexafluoride (SF6) from SF6/N2 mixtures is of great importance. Herein, three metal-organic frameworks with fine-tuning pore structures, Cu(peba)2, Ni(pba)2, and Ni(ina)2, were ...

Fault Diagnosis of SF6-Insulated Equipment by Micro Gas Sensor Array

IEEE Transactions on Power Delivery, 2023
SF6 decomposition products could reflect the running status and inner faults of power equipment, and it's expected to realize a timely warning. In this work, six faults including spark and corona discharge were simulated, and SF6 decomposition products ...

SOF2 sensing by Rh-doped PtS2 monolayer for early diagnosis of partial discharge in the SF6 insulation device

, 2021
In this paper, Rh-doped S-vacancy PtS2 (Rh-PtS2) monolayer is proposed as a novel sensing material for SOF2 detection in order to evaluate the operation status of SF6 insulation devices.

Quantitative Detection of Multicomponent SF6 Decomposition Products Based on Fourier Transform Infrared Spectroscopy Combined With CARS-ELM Algorithm

IEEE Transactions on Instrumentation and Measurement, 2022
The decomposition of SF6 as an insulating medium in gas-insulated switchgear (GIS) in the event of partial discharges (PDs) leads to insulation failure inside the equipment.

Breakdown field strength of SF6, N2O, SF6+N2, and SF6+N2O

Journal of Applied Physics, 1981
The breakdown voltages of some electron attaching gases and gas mixtures have been calculated from their fundmental properties such as ionization and attachment cross sections, the momentum transfer cross section, the drift velocity or the mean energy of electrons.

An Effective Low-Contrast SF₆ Gas Leakage Detection Method for Infrared Imaging

IEEE Transactions on Instrumentation and Measurement, 2021
Infrared noncontact detection has the advantages of having no power cut-off and convenient operation. However, when the SF6 (sulfur hexafluoride) gas leakage is small, the existing detection algorithms have low accuracy and are easily disturbed by noise.

Electrical breakdown of N2O, SF6 and N2O/SF6 mixtures

Proceedings of the Institution of Electrical Engineers, 1974
Measurements of static breakdown voltages were made for SF6 and N2O/SF6 mixtures containing between 1% and 50% SF6 by volume for values of Nds within the range 1023 < Nds < 1024 m−2 (where N is the gas number density and ds the sparking distance). These results, together with earlier data on N2O, show that the departures from Paschen's law become ...

SF6 ReUse Concept and SF6 New Applications

1998
Solvay is a worldwide supplier of SF6 since the late nineteen sixties and started to develop a ReUse concept for used SF6 at the begining of 1990. the ReUse concept was developed for SF6 coming from electrical equipment, where most of the worldwide SF6 production is used.
