OSA | Highly sensitive SO2 photoacoustic sensor for Sulfr hexafluoride

IntroductionSelection of SO2 Detection Wavelength and Excitation Optical SourcePhotoacoustic Cell DesignExperimental Setup of Sensor SystemConclusionsIn electric power systems, sulfur hexafluoride (sf6 gas) has been widely used as an insulating medium in gas circuit breakers (GCBs), gas-insulated switchgears (GIS), transformers (GIT), and transmission pipes (GIL) since pure gaz sf6 gas is noninflammable and highly reliable due to its chemical inertness. Due to the presence of electric arcs, sparks or coronas in electric power systems, insulating gas can be decomposed via the electronic, thermal and optical processes into sulphur fluorides (SF2, SF3 and SF4), which in turn react with electrodes and gas impurities (trace amounts of air and water vapor) to form various chemically active by-products (such as SOF4, SOF2, SO2F2, SO2, CO and H2S). The composition and decomposition rates vary with changing insulating defects. The accumulation of these by-products has led to concerns regarding personnel safety and material compatibility problems. The monitoring of decomposed by-products is able to identify and determine the occurrence of fault types in elec...Get price
