Abstract. By detecting the decomposition gases of sulfur hexafluoride (SF 6 ), the type of internal fault of gas insulated switchgear (GIS) can be determined. In this paper, the scandium atom doped molybdenum sulfide material (Sc-MoS 2) was proposed, and the adsorption behaviors of four typical SF 6 decomposing gases (H 2 S, SO 2, SOF 2, SO 2 F 2) on the surfaces of intrinsic MoS 2 and Sc-MoS 2 are studied based on density functional theory (DFT) method.Get price

Drying and particle filters absorb moisture, gas and dust

On the suspicion that SF 6 gas in a circuit breaker is contaminated or humid, we strongly recommend the use of drying and particle filters between switchgear and service cart. Moisture and both gaseous and dusty decomposition products as well as oil aerosols are adsorbed by special drying and particle filters during the recovery operation. Thus, service carts are protected effectively against contamination as most of the moisture and decomposition products are collected by the prefilter units.Get price
