Abstract

gas mixtures are regarded as the most promising alternatives to SF

gas in the near future. Research on mixing ratio detection of SF

gas mixtures in electrical equipment plays an important role in equipment state assessment. This paper presents a detection technology of mixing ratio

based on a thermal conduction sensor

and develops a detector

which is able to detect the mixing ratio of SF

/CF

/Air and SF

/CO

with a measurement accuracy and standard deviation both b

etter than 1.5%. Moreover

this detector can be used easily to rapidly measure the mixing ratio on site with low gas consumption

and the accuracy of the results and feasibility of field detection has been verified by a large amount of test data.
