Description

technical field

[0001] The invention relates to the field of electrical equipment detection, in particular to a refillable sulfur hexafluoride decomposition product chromatographic on-line detector. Background technique

[0002] With the rapid development of the power industry, the number of sulfur hexafluoride electrical equipment continues to increase. Under electric arc, spark discharge, high temperature and other factors, sulfur hexafluoride gas is easy to ionize and decompose, and its decomposition products react with moisture and oxygen in electrical equipment to form SO 2 、H 2 S, HF and other acidic substances, and SF 4 、SOF 2 , SF 2 , SO 2 f 2 highly toxic and corrosive substances. Therefore, the detection of sulfur hexafluoride decomposition products, especially the detection of various decomposition products, is of great significance for judging the operating status, fault cause, discharge level and danger degree of electrical equipment.
