Mikrosensorik SF6 decomposition joints Wireless Sensors

Sulphur hexafluoride (SF<SUB6</SUB) is used as an insulator in high voltage systems. Electrical breakdown in such a system dissociates SF<SUB6</SUB into sulphur fluorides, sulphur and fluorine. Some of these products react with contaminants such as water vapor and oxygen, and with metal surfaces and electrodes, to produce by-products including gaseous sulphur oxyfluorides, hydrogen ...

  • NDIR SENSORS FOR SF6 MEASUREMENT - smartGAS Mikrosensorik

    SF6 (sulphur hexafluoride) is a non-com- bustible and non-toxic gas. Throughout the world it is used primarily for insulating electrical high-voltage switching systems, transformers and cables. It is also used as an etching gas in semiconductor produc- tion and as a tracer gas in environmental simulations. The sensors measure either the purity and quality of the insulating gas in the systems or reliably detect minute SF6 quantities in indoor air.

    However, part of SF6 decomposes into different components under partial discharge (PD) conditions. Previous research has shown that the gas responses of intrinsic and 4 Å-type molecular sieve-deposited multi-wall carbon nanotubes (MWNTs) to SOF2 and SO2F2, two important decomposition components of SF6, are not obvious.

    Sep 25, 2020 · Abstract. SF 6, as an outstanding insulation medium, is widely used in the high-voltage insulation devices, guaranteeing the safe operation of the power system. Nevertheless, the inevitable partial discharge in a long-running device causes the decomposition of SF 6 and deteriorates its insulation performance. In this work, DFT calculations were performed to study the adsorbing and sensing properties of ZnO-modified C 3 N (ZnO-C 3 N) nanosheet towards SF 6 decomposed products, in order to
