变压器.不大于2500kva的地下型三相配电变压器:高压不大于34500y接地19920伏低压不大于480伏.要求 - By fuzzying these parameters and calculating the membership degree , fault characteristic vectors are designed and analyzed by gray relational degree ( grd ) , which could open a new way for fault classification and identification , including diesel vibration diagnosis by combining the ea and fuzzy method with the grd
对特征参数进行模糊处理和隶属度计算，在此基础上设计出故障特征向量，进行灰色关联度分析，从而把包络解调分析、模糊数学和灰色关联分析有机结合在一起，综合它们的优势，进行故障分类和识别，为机械设备的故障诊断提供一条新的思路。
