摘要

为进一步提升变压器油中腐蚀性硫化物的检测灵敏度，该文首次将互相关检测应用于拉曼光谱的定量分析中，并提出多输入信号修正的相关检测方法，通过理论推导证明了该方法可增强拉曼光谱信号。以变压器油中的典型硫腐蚀特征分子二苄基二硫醚为例，采用传统定量分析方法时质量浓度检测下限为338.51 mg/kg，应用相关检测后检测下限达到178.29 mg/kg，检测下限提升了1.90倍。而进一步应用多信号输入修正的相关检测方法后，针对弱信号的检测能力随着通道数的增加而增强。当输入信号通道数达到25时，19.5 mg/kg二苄基二硫醚样品的检出率即可达到100%。最后通过实验室配制固定浓度样品进行验证试验，证实了相关检测方法与多信号输入修正方法的可靠性和有效性。此方法同时可应用于其他特征物分子的检测中，以及其他基于图谱的检测方法中，如红外光谱检测、质谱检测等。

Abstract

In order to further improve the detection sensitivity of corrosive sulfides in transformer oil

the correlation detection theory is introduced to the Raman spectroscopy quantitative analysis for the first time

a multi-channel signal modified correlation detection method is proposed

and all methods are mathematically proved. Taking dibenzyl disulfide

a typical corrosive sulfides molecule in transformer oil

as an example

we use the traditional quantitative analysis method and find that the limit of detection is 338.51 mg/kg. After the correlation detection is introduced

the limit of detection reaches 178.29 mg/kg

an increase of 1.90 times is achieved. After applying the multi-channel signal modified correlation detection method

the detection sensitivity for weak signals is further enhanced as the channels number increases. When the channels number reaches 25

the detection rate of 19.5 mg/kg dibenzyl disulfide samples can reach 100%. Finally

the reliability and effectiveness is demonstrated by fixed concentration samples test. These methods can also be generalized to chromatography

mass spectrometry and other spectra based detection methods.
