Among several neutral oils, transformer oil shows the best agglomeration effect. For the complex tailings, in which over 90% of molybdenum distributed in the range of -0.038 mm, the optimal dosage of transformer oil and frother was about 12 kg/t and 0.5 kg/t respectively, and the least agitation time and rate should above 3 min and 400 r/min, respectively.

结果表明，在众多中性油中，变压器油表现出了较好的油团聚浮选效果，对于钼金属分布率高于90%的-0.038mm粒级的浮选尾矿，其合适用量需达到12kg/t左右，与之配合的起泡剂用量在0.5kg/t左右，油团聚时间及搅拌强度分别需达到3min和400r/min以上。

This paper combines the movement of the qu-zhou electric Power bureaus actual with the three phase oil immersed transformer as example, thorough analysis the fault regulation of electrical transformer, putting for...

本文结合衢州电力局的运行实际，以油浸式变压器为例，深入分析变压器的故障规律，提出了变压器状态检修策略，并依此制定状态检修应用导则，在实际中得到很好的应用，指导了状态检修工作的开展。

The research aim of this thesis is the winding end insulating structure of oil immersed power transformer 110kV . Beause of the very asymmetric electric field, the higher electric field would apeared in the oil-gap and partial charge will easily engendered in the wedge oil-gap between static ring and head block of winding end.The two-dimensional isoparametric and finite element method is used for analyzing and calculating the electric field distribution in high voltage winding end insulating structure.

本文以110kV油浸电力变压器绕组端部绝缘结构为研究对象，针对绕组端部绝缘结构中静电屏与垫块之间存在楔形油隙区，致使电场分布很不均匀，油隙区中的电场强度较高，容易产生局部放电的特点，采用二维等参元有限元法及有限元软件ANSYS电磁场分析功能对高压绕组端部绝缘结构进行电场计算分析。

The conclusion that dissolved gases in gas composition and content of transformer could embody the inside of the transformer"s situation about "the insulation fault effectively is concluded.In the research of power equipment fault diagnosis based dissolved gases in transformer oil, the fault type increase clearly with the fault development. Traditional way is inability to faults diagnose of electrical equipment such as transformer that the fault reason, phenomenon and principle are indeterminacy etc.

在以油中溶解气体分析电气设备故障的模式识别研究中，当故障进一步发展，待判别的类型将显著增加，由于传统的诊断方法缺乏对样本数据的科学分析，不能够真实体现特征量数据的规律，将不可避免的面临准确率下降的问题，且不可能提供类间相互关系或演变过程的信息，因此用新的诊断方法来解决此类问题十分必要；本文在对目前变压器内部绝缘故障常用诊断方法总结分析的基础上，利用模糊数学的思想，提出以油中溶解气体为特征量，采用模糊聚类的方法对变压器内部绝缘故障进行诊断。
