摘要气体光声光谱检测技术能很好地应用于变压器油中溶解气体的在线监测。温度是光声光谱检测的重要影响因素之一。论文基于光声光谱技术的基本原理,利用分布反馈半导体激光器构建了一种便携式、可调谐的光声光谱装置；在分析光声池声学理论的基础上,结合实验探讨了温度对光声池池常数、谐振频率以及气体吸收系数的影响。以变压器油中主要特征气体C₂H₂进行实验分析,得到了乙炔气体光声信号与温度之间的关系曲线,理论及实验结果为进一步完善油中气体光声光谱在线监测系统奠定了重要基础。

Abstract：Gas photoacoustic spectroscopy (PAS) can be well applied in transformer oil-dissolved gas detection online monitoring. The effect of temperature on the photoacoustic spectroscopy detection is significant. A portable and tunable experimental setup with a distributed feedback diode laser is developed based on the fundamental of PAS in the paper. The influences of temperature on photoacoustic cell constant, resonant frequency and gas absorption coefficients with the experiments are discussed. Based on the experimental analysis of the acetylene dissolved in transformer oil, the relationships between acetylene photoacoustic signal and temperature are given. The theoretical and experimental results laid an important foundation, for the further improvement in oil gas photoacoustic spectroscopy of on-line monitoring system.

Key words： Dissolved gas-in-oil photoacoustic spectroscopy photoacoustic cell temperature characteristic
