Abstract

SOF

is an important component of SF

gas discharge decomposition in gas insulated switched（GIS）.Online monitoring of SOF

gas concentration in GIS can effectively reflect the operating state of GIS in real time.In view of the fact that the traditional tin dioxide-based gas sensor detects the SF

decomposition component

the working temperature is high and the gas response sensitivity is low.This pape

r proposes a hydrothermal method for preparing gold nanoparticles/tin dioxide/reduced graphene oxide（AuNPs-SnO

-RGO） hybrid nanomaterials for the detection of SF

gas discharge decomposition components.The gas-sensing properties of AuNPs-SnO

-RGO hybrid materials were studied by exposure to SOF

.Results showed that AuNPs-SnO

-RGO sensors had desirable response/recovery time.Compared with pure RGO（’396/748 s） and SnO

/RGO（302/467 s）

the response/recovery time ratios of AuNPs-SnO

-RGO sensors for 50 μL/L SOF

at 110 ℃ were 41/68 s

respectively.Furthermore

the sensor has good repeatability and stability.Finally

the sensing mechanism of the prepared sensor is discussed.
