Online monitoring device and calibration method for gas in transformer oil

According to the online monitoring device and calibration method for the gas in the transformer oil, the corrected gas concentration value Ni of a gas component i serves as the standard concentration value of the gas component i in a degassing sample gas source (20), and due to the fact that the corrected gas concentration value Ni of the gas component i is designed, the standard concentration value of the gas component i in the degassing sample gas source (20) is obtained; therefore, the data precision of the on-line monitoring device for the gas in the transformer oil is improved. 一种用于变压器油中气体的在线监测装置和标定方法，以气体组分i的修正后气体浓度值Ni为脱气样气源(20)中的气体组分i的标准浓度值，由于设计了气体组分i的修正后气体浓度值Ni，得到脱气样气源(20)中的气体组分i的标准浓度值，因此提高了变压器油中气体在线监测装置数据精度。
