Description

technical field

[0001] The invention relates to the field of sulfur hexafluoride gas quality analysis, in particular to a sulfur hexafluoride gas quality analysis system. Background technique

[0002] Sulfur hexafluoride (SF6) has good insulation and arc extinguishing properties, and is commonly used in gas-insulated combined electrical appliances. The content of air, carbon tetrafluoride, hexafluoroethane, octafluoropropane and water needs to be tested before use. In the market, the pulse discharge helium ionization detector is commonly used for detection and analysis, but it has the disadvantages of expensive analytical instruments and high requirements for operators. Contents of the invention

[0003] In view of the above problems, the present invention provides a sulfur hexafluoride gas quality analysis system to realize the analysis of air, carbon tetrafluoride, hexafluoroethane, octafluoropropane and water components in the sulfur hexafluoride gas.
