摘要
Abstract
Filed detection of SF6 gas decomposition products was combined with chromatographic analysis in laboratory to realize long-term monitoring of SF6 high-voltage DC bushing.In an electrical test,no defect was found with the bushing,however,the detection of SF6 decomposition products revealed internal defect and issued a warning in time.The disassembly inspection revealed obvious superheated trace and a large amount of solid powder on the bushing surface,verifying the validity and reliability of the SF6 decomposition products monitoring method for state diagnosis of SF6 equipment.关键词
