Adsorption Behavior of Ni-Doped ZnO Monolayer upon SF6 ...· In this article, Ni-doped ZnO (Ni-ZnO) monolayer is proposed as a potential sensing material for detection of two SF6 decomposed components (namely, SO2 and SOF2), based on the density functional theory (DFT) method, to monitor the operation status of SF6 insulation devices in the power system. The Ni-doping effect on the physicochemical properties of the pure ZnO monolayer is first …

HIS - Highly Integrated Switchgear, Type 8DQ1· Sulfur hexafluoride (SF6) is used as the insulating and arc-quenching gas. All modules are attached to one another with flanges. The gas-tightness of the flange joints is ensured by the Siemens O-ring sealing principle, proven over decades of service. Gas-tight bushings permit subdividing the bay into several distinct gas compartments.
