摘要

Device and method based on spectrofluorimetry for simultaneous determination the content of ethylene and ethane in the power transformer oils of the present invention refers to a device pairThe detection of ethene (C2H4) and ethane (C2H6) in the insulating oil for power transformers.More specifically, the device can detect lines in power transformers considering that these are the main gases that occur when the processor is operating at temperatures CAIma of the supported.More particularly, the wavelengths of emission and excitation for the detection of these gases was made by correlating the fluorescence spectrum with the gas concentrations determined by aThe reference method, such as gas chromatography by least squares regression (PLS) English, partial least squares regression).On the basis of the wavelengths determined by PLS model was constructed, a sensor for determining the gas bench ethane and ethene dissolved in insulating oil.The invention has the potential application in transformer industry and electric power distribution.
