The main content is to introduce the analysis and detection technology of sulfur hexafluoride gas, including two major parts: laboratory detection technology of sulfur hexafluoride gas and on-site detection technology of sulfur hexafluoride electrical equipment. It also includes relevant basic knowledge that testing technicians must possess, namely basic characteristics of sulfur hexafluoride gas, basic knowledge of analytical chemistry, detection error analysis, and data processing knowledge. In addition, This article elaborates on the gas analysis technology for fault diagnosis of sulfur hexafluoride electrical equipment, the supervision and management of sulfur hexafluoride new gas, operating gas, and electrical equipment, as well as the monitoring standards for sulfur hexafluoride used in power equipment. At the same time, attention was also paid to the greenhouse effect of sulfur hexafluoride and its recycling, treatment, and reuse technology
