Problems solved by technology

[0002] Due to its instability, the decomposition products of sulfur hexafluoride gas are easily disturbed by the external environment during the sampling process, resulting in discrepancies between the laboratory test results and the actual situation. Accurately determine the nature and degree of the internal faults of the equipment. Therefore, it is necessary to develop a mobile test system for the state detection of sulfur hexafluoride equipment, so that it has the ability to analyze the full components of sulfur hexafluoride decomposition products
