为了消除电力Transformer油中溶解气体在线检测中费时的油气分离过程，提出将光纤光栅（FBG）氢气传感器直接安装在电力Transformer油中。在传感器设计中，FBG包层被侧面抛光，剩余厚度为20 μm，并用钯/银溅射。由于侧面抛光包层是非常敏感的曲率应变引起的钯在溶解氢的存在下，所提出的传感器是更敏感的比未经处理的FBG氢传感器。测试结果表明，该传感器的灵敏度高达0.477（pm/（μL/L）），是传统光纤光栅氢气传感器的11.4倍。此外，还研究了重复性和短期稳定性。性能满足电力Transformer油中溶解氢浓度监测的实际需要。
To eliminate the time-consuming oil-gas separation process in online dissolved gas detection of power transformer, fiber Bragg grating (FBG)-based hydrogen sensor is proposed to be installed into the power transformer oil directly. In the sensor design, the FBG cladding is side-polished with a residual thickness of 20 μm and sputtered with palladium/silver. Since side-polished cladding is very sensitive to curvature strain induced by palladium in the presence of dissolved hydrogen, the proposed sensor is much more sensitive than the untreated FBG hydrogen sensor. Measurements prove that the sensitivity is as high as 0.477 (pm/(μL/L)), about 11.4 times higher than the conventional FBG hydrogen sensor. Furthermore, repeatability and short-term stability have been investigated. The performances satisfy the actual need of monitoring dissolved hydrogen concentration in power transformer oil.
