- W4213372419 abstract "Power transformer is the core equipment of the power network, and vibration detection is an important technical means to analyze the mechanical state of the inner winding and iron core of the transformer. Compared with the traditional vibration sensor, the optical fiber vibration sensor has the advantages of anti-electromagnetic interference, easy reuse and high sensitivity. This paper designed a FBG vibration sensor based on the structure of cantilever beam, and based on the theory analysis and COMSOL simulation design the sensor structure vibration picking, improves the sensor sensitivity of low frequency vibration of transformer, set the edge spectrum of fiber grating demodulation system, simplifying the system structure, has realized the sensing of low frequency vibration signal. Based on the shaking table, the measured resonant frequency of the sensor is 180Hz, and the sensitivity at the resonant point is 14.09V/g. The sensor has good linearity at 100 Hz and can detect vibration signals lower than 0.0176g." @default.
