The Design of a Laser Photoacoustic Spectrum Transformer Oil and Gas On-line Monitoring System

It’s an effective method to judge the operation state of transformer by measuring the composition and proportion of gas in oil-paper insulated power transformer oil. An on-line monitoring system for transformer oil and gas by laser photoacoustic spectroscopy is designed based on resonant laser photoacoustic spectroscopy and wavelength modulation, it can realize the continuous measurement of transformer oil and gas, the light source is semiconductor laser, which can avoid the problem of gas cross interference existing in traditional photoacoustic spectroscopy. At the same time, the system makes use of ubiquitous Internet of things technology to realize real-time data viewing and reading, which can facilitate the management of oil and gas equipment.
