Abstract


In recent decades , SF6 gas as an excellent dielectric and arc-quenching medium, high voltage electrical equipment insulation areas to be more widely used, but the SF6 gas in the presence of moisture , seriously affect its insulating properties, so the SF6 electrical the device for detecting the humidity of the gas is very important. At present, domestic power system using micro-water detection methods are mainly electrolytic method , dew point method and the RC method . These methods have a very big disadvantage is that when measuring air consumption are large , SF6 is an expensive gas , but also a source of pollution. In addition to testing large consumption can cause environmental pollution, but also cause excessive pressure drop within the device and affect normal operation of equipment or increase qi work . Therefore , this paper proposes a new detection method - gas chromatography , creatively put forward the enrichment enrichment technology to solve the separation of water and SF6 critical pain points and using a thermal conductivity detector for detection. Finally, the principle of the issue for a lot of validation testing machine comparison test results show that the method is very effective and has a certain application prospect and popularization value .
