Embodiment Construction
[0010] Such as figure 2 As shown, the present invention provides a method for monitoring the breakdown of parallel arrester groups based on grating temperature measurement, which includes the following steps: first, a fiber optic grating temperature sensor is evenly installed on the outer wall of the insulating porcelain bottle of the arrester group, and the temperature data of the arrester group is collected. The obtained optical signal is demodulated and converted into a digital signal through the data acquisition device. The wireless transceiver device packs the digital signal and transmits it to the data processing device through wireless mode. When the data processing device finds that the temperature of the arrester group exceeds the threshold, it will alarm.
[0011] Wherein the data processing device collects the temperature data of the arrester group in real time, compares the temperature data with the historical temperature data of the arrester group, and compares th...
