摘要:
提出一种正-负-零的面积关联度,通过其计算数值,确定待诊断变压器油中溶解气体序列和标准故障模式序列间的相似性与相近性.实例分析表明,正-负-零面积关联度诊断的结果与实际情况完全吻合,与传统的灰色面积关联度相比,能更全面、更准确地诊断变压器的内部故障类型.
Abstract:
An area relational grade is put forward,the value of which can be positive,negative or zero,to determine the similarity and the proximity between the content sequences of dissolved gases in the transformer oil to be diagnosed and the sequences of standard fault modes by calculating its value.The case study has indicated that the results of the diagnosis based on the area relational grade fit those in the actual situations completely,which can diagnose the inside fault types in the transformer more completely and accurately compared with the traditional gray area relational grade.
