Sensitive Characteristics Analysis on 4A Molecular Sieve Doped Carbon Nanotube Sensor for Detecting SO_2

SO2 is an important characteristic component of SF6 decomposition under partial discharge(PD), so its content and varying pattern are adopted to evaluate PDs in SF6 gas insulated equipment. To improve intrinsic carbon nanotubes gas sensors, which have poor sensitivity to SO2, we proposed a kind of gas sensor made of sieve-doped carbon nanotubes. We experimentally investigated the sensitivity of this 4A molecular sieve-doped carbon nanotube gas...
