摘　　要：SF6气体绝缘电气设备目前已被广泛地应用于电力行业中,因此通过检测SF6气体衍生物的成分和含量来对气体绝缘电气设备进行状态检测成为了一个重要的技术手段。基于光学方法的气体检测技术是目前最有效的检测技术之一,但受气体本身的光谱性质所限,在检测光学波段内往往会出现混合气体中各组分吸收峰重叠的现象,即交叉干扰,导致各组分的体积分数难以被准确测量,从而难以对气体绝缘电气设备内的潜在故障进行准确判断,降低电气设备运行的安全性和可靠性。因此,必须对交叉干扰进行校正以保证检测结果的准确性。本文研究了现阶段各类应用于微量气体检测的交叉干扰处理技术,总结了各处理技术的优势与缺点,并对相关技术进行展望,旨在为采用光学方法进行微量气体检测的相关人员提供参考。SF6-based gas insulated equipment is now widely applied in various fields of electrical power system.Thus,state detection for relevant equipment possesses considerable practical meaning.Nowadays,decomposition products analysis is the most common and effective method in monitoring gas insulated equipment.However,due to the characters of gas,absorption peaks overlap may occur in detection wavelength range,which causes crossover interference.Crossover interference may pile up the difficulty of measuring volume fraction accurately.As a result,the situation in gas insulated equipment cannot be diagnosed correctly,and the safety and reliability of electrical equipment would decrease consequently.This paper firstly summarizes current researches about crossover interference processing methods.Then,pros and cons of each processing method are concluded.As last,further issues to be solved and possible development directions are put forward.
