Recently, with the strong support from the project of "one hundred billion yuan industry" in the autonomous region, Guangxi Electric Power Academy completed the construction of the first sulfur hexafluoride solid analysis laboratory in Guangxi, indicating that the sulfur hexafluoride sulfur dioxide electrical equipment Fault diagnosis technology into a new level. The sulfur hexafluoride solid decomposition testing laboratory is an important part of the SF6 key laboratory construction in the hospital. It is mainly composed of ICP-MS and related supporting equipment. The system is characterized by high temperature ( 7000K) ionization features combined with the sensitive, fast scanning advantages of quadrupole mass spectrometers for the elemental and isotopic analysis of sulfur hexafluoride for the analysis of elemental composition of sulfur hexafluoride solid decomposition products for rapid diagnosis of internal sulfur hexafluoride electrical equipment failures What happened? At present, Guangxi Electric Power Academy has completed the installation and commissioning, performance acceptance and technical training of the ICP-MS analysis and testing system, and chemical technicians are working hard to carry out practical application studies. The completion of sulfur hexafluoride solid decomposition testing laboratory, for the safe operation of sulfur hexafluoride electrical equipment to provide a new analytical techniques.
