摘要
推导了变压器油中溶解气体的分离数学模型，建立了一种用光纤Ｍ－Ｚ干涉仪对低浓度氢气进行检测的实验系统．通过对气室引入声波调制手段，消除了环境因素对干涉仪的干扰。
A mathematical model for separating the hydrogen dissolved in transformer oil is developed. An experimental setup is built to measure extremely low hydrogen concentration based on a fiber optic M Z interferometer. By introducing sound wave modulation to the gas cell, all kinds of environmental interference to the interferometer are significantly reduced and the sensitivity of hydrogen concentration measurement is greatly improved.
