变压器的安全运行是核电站平稳发电的保证。变压器油色谱在线检测装置是利用油中色谱分析原理（定性，定量分析溶于变压器油中的气体来实现）来检测变压器的潜伏性故障，而对判断充油设备电器内部故障有价值的气体，即氢气，甲烷，乙烷，乙炔，乙烯，一氧化碳，二氧化碳等称为特征气体。本文对现在市场上主要的在线监测设备原理及运行效果进行了简单的总结。根据方家山核电调试及运行阶段遇到的问题，对方家山核电所使用在线检测设备给出了运行评价，希望能给相关从业人员一定的参考。%The safe operation of transformer is the assurance of smooth plant power generation. Transformer oil chromatogram on-line detection device is the use of oil chromatographic analysis principle (qualitative and quantitative analysis of the gases dissolved in transformer oil) to detect transformer latent fault. For judging oil-filled equipment electrical internal fault valuable gas, hydrogen, methane, ethane and acetylene, ethylene and carbon monoxide, carbon dioxide and other gases called characteristics. Now in the market, the author of this paper is mainly the online monitoring principle and effect has carried on the brief summary. According to some problems in Fang jia shan nuclear commissioning and operation stages, I gave my evaluations to Fang jia shan nuclear power plant by using the online testing equipment, hoping it can give certain reference related professionals.
