【 摘 要 】

Acetylene (C2H2) is one of the major fault characteristic gases dissolved in the oil of power transformer, which can reflect the discharge fault of transformer effectively. This paper presents three kinds of ZnO nanosensors with different morphology and structure. Based on the laboratory platform, their detection characteristics and gas sensitive mechanism of dissolved C2H2 in transformer oil are studied. The results indicate that, owing to the larger specific surface area, the flowerlike ZnO nanosensor maintains good linearity and stability and has higher sensitivity and rapider response than the rod-like and granular ZnO nanosensors. The results provide a new idea for the research of high performance C2H2 ZnO sensor.
