摘要
针对现有变压器油中气体故障诊断"三比值法"对比值分界值绝对化而造成误诊的缺点,本次研究提出把"模糊原理"和"无编码比值法"相结合,从而产生的一种新的变压器故障诊断方法"模糊无编码比值法"。根据大量的实践经验,编写软件实现了"无编码比值法"分界点的模糊处理和比值评判,通过大量的故障数据验证证明,"模糊无编码比值法"比现有的"三比值法"有更高的判断准确度。
Based on the original in transformer oil gas fault diagnosis ＂three ratio method＂ the ratio of boundary caused by the hard-core misdiagnosis of faults, proposed has mature technology ＂fuzzy principle＂ and be practice has proved accurate ＂no coding ratio method＂ combination, and produce a new type of transformer fault diagnosis method ＂Fuzzy no coding ratio method＂, and with ＂three ratio method＂ accuracy is software realization demonstration.
