摘要

研制了一种基于谐波检测的光纤传感器，用于实时监测高压变压器绝缘油中溶解气体的故障检测。本工作描述了对传感器系统的优化贡献，使用由锁相放大器的本振调制的DFB激光器，也用于被测气体分子谱线的谐波检测。以C2H2和CO为测试气体，对传感器的优化进行了详细的研究。

Contributions to the optimization of an optical sensor for acetylene and carbon monoxide

An optical fiber sensor based on harmonic detection for real time monitoring of dissolved gases in the insulating oil of high-voltage transformers has been developed for fault detection. The present work describes contributions to the optimization of the sensor system, using a DFB laser, which is modulated by the local oscillator of a lock-in amplifier, also used for harmonic detection of the spectral line of the gas molecule under test. A detailed study was developed toward sensor optimization by using C2H2 and CO as the test gases.
