However, part of SF6 decomposes into different components under partial discharge (PD) conditions. Previous research has shown that the gas responses of intrinsic and 4 \u00c5-type molecular sieve-deposited multi-wall carbon nanotubes (MWNTs) to SOF2 and SO2F2, two important decomposition components of SF6, are not obvious. In this study, a K-type molecular sieve-deposited MWNTs sensor was developed. Its gas response characteristics and the influence of the mixture ratios of gases on the gas-sensing properties were studied. The results showed that, for sensors with gas mixture ratios of 5:1, 10:1, and 20:1, the resistance change rate increased by nearly 13.0% after SOF2 adsorption, almost 10 times that of MWNTs sensors, while the sensors\u2019 resistance change rate with a mixture ratio of 10:1 reached 17.3% after SO2F2 adsorption, nearly nine times that of intrinsic MWNT sensors. Besides, a good linear relationship was observed between concentration of decomposition components and the resistance change rate of sensors.<\/jats:p>","DOI":"10.3390\/s151128367","type":"journal-article","created":{"date-parts":[[2015,11,12]],"date-time":"2015-11-12T03:46:55Z","timestamp":1447300015000},"page":"28367-28384","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Analysis of the Sensitivity of K-Type Molecular Sieve-Deposited MWNTs for the Detection of SF6 Decomposition Gases under Partial Discharge"],"prefix":"10.3390","volume":"15","author":[{"given":"Xiaoxing","family":"Zhang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment & System Security and New Technology, Chongqing University, Chongqing 400044, China"},{"name":"School of Electrical Engineering, Wuhan University, Wuhan 430072, China"}]},{"given":"Xin","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment & System Security and New Technology, Chongqing University, Chongqing 400044, China"}]},{"given":"Chenchen","family":"Luo","sequence":"additional","affiliation":[{"name":"Maintenance Company, State Grid Zhejiang Electric Power Company, Hangzhou 311232, China"}]},{"given":"Xingchen","family":"Dong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment & System Security and New Technology, Chongqing University, Chongqing 400044, China"}]},{"given":"Lei","family":"Zhou","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment & System Security and New Technology, Chongqing University, Chongqing 400044, China"}]}],"member":"1968","published-online":{"date-parts":[[2015,11,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"164","DOI":"10.1016\/S0925-4005(04)00415-0","article-title":"Detection of partial discharge in SF6 gas using a carbon nanotube-based gas sensor","volume":"2","author":"Suehiro","year":"2005","journal-title":"Sens.
