摘　　要：基于故障标准谱定义了n维空间模式集合,根据欧氏距离构造了一种几何分类器。分类器结构简单,具有较强的抗干扰能力,且易于实现,因而适合在线故障诊断。文末给出的实例证明了分类器的有效性。Based on normative spectrum, modes for transformer is defined, a geometry classifier is developed with Euclidean distance, which is of simple structure and antijamming capability, so classifier is easily realized and suitable to be inserted into diagnosis systems on line. Finally, an example is given to illustrate our results based on dissolved oxygen analysis(DGA)and comparisons with previous related research results are made, which shows our method is valid.
