Cable Channel Fire Monitoring Method Based On Photoacoustic Spectrum

With the continuous expansion of urban scale, the proportion of cable lines in urban distribution network is increasing, but the maintenance and monitoring of cable channels are generally difficult, which makes it impossible to effectively monitor the fire in cable channels. Photoacoustic spectrum monitoring technology has the characteristics of sensitive detection, high accuracy and convenient installation, which provides a new research idea for realizing cable channel fire monitoring. Combining the high sensitivity and high accuracy of photoacoustic spectroscopy monitoring technology, this paper realizes the accurate identification and location of cable channel fire, and improves the power supply reliability of distribution network.
