变压器常见故障的诊断

The Diagnosis of the Common Faults of the Transformer

对于变压器常见故障的诊断一是根据变压器电流、电压、油位、油色、声音等方面发生的变化,进行初步分析和判断;二是结合油质分析、电气试验以及设备运行、检修等情况进行综合分析,对故障的部位、原因、绝缘或部件的损坏程度等做出准确判断并制定合理的处理方案。

For the diagnosis of the common faults of the transformer, the first thing is to make the primary analysis and identification based on the variations of the electric current, electric voltage, oil level, oil color, and noise, etc. the second thing is to make comprehensive analysis connecting with the oil-quality analysis, electrical test and equipment operating and inspecting situation, and make accurate diagnosis on the positions and reasons of the faults and the damage extents of the insulation and parts and work out rational treating schemes.
