摘要
分解气体分析法通过检测故障产生的气体组分诊断设备故障,是检测电力设备故障的重要方法,某些应用场合具有不可替代的作用。然而目前该方法只在绝缘油、SF_6等绝缘介质的场合有应用,对于空气这一最重要的绝缘介质还没有应用。文中在简述空气放电衍生物气体产生理论的基础上,分析了采用分解气体分析法检测空气中放电的可行性,并对相关分解气体分析法的应用及研究现状、空气分解气体产生规律等进行了综述。最后提出需要进一步研究问题包括空气气体分解演化规律及影响因素、气体特征与放电的关系、放电识别方法等。
Fault diagnosis based on the decomposition gas analysis method （DGAM） is through the examination of the composition of the decomposed gases produced in a fault. It is an important method for the detection of equipment fault and irreplaceable in some applications. However this method is at the moment only applied to insulation oil and SF6 gas. There has been no application to air insulation so far. In the present work, the feasibility of discharge diagnosis in air by monitoring the decomposed gases is studied considering the relevant theory on the formation of discharge products. In addition, a review has been carried out on the present research and application of the decomposition gas analysis method. Future work is also proposed that includes the decomposition and formation of chemical species and the influencing factors, relationship between gas properties and discharge behavior, and finally the method to recognize partial discharges.
