一起变压器故障分析与判断的实例

An Lnstance of Fault Analysis and Judgement in the Transformer

变压器的内部故障会使变压器油或固体绝缘材料分解,产生气体并大部分溶于油中,其产气速率和产气量与变压器的内部故障性质有很大关系。本文针对具体故障实例,采用对变压器油中气体含量进行分析并结合高压试验及变压器的运行状况判断的方法比较准确的定位出故障。

The inner faults in the transformer may resolve the oil or solid insulation material in the transformer, producing gas which dissolves in the oil. The speed and amount of gas-producing have much to do with the inner fault properties. This paper analyzes the gas content in the oil in the light of high pressure experiment and the transformer＇s operation to locate the fault in specific instances.
