110kV倒置少油电流互感器金属膨胀器含氢拉伸的故障分析

Fault Analysis of Hydrogen-Containing Tension in Metal Expander of 110kV Inverted Low Oil Current Transformer

该文的主要内容是根据工作经验对110kV倒置少油电流互感器金属膨胀器含氢压缩的故障原因进行介绍,从该互感器故障前后的色谱分析情况、结构特点、解体检查结果以及油浸式电流互感器、氢气超标的原因等进行综合分析,希望能够帮助读者,对于该方面的知识有进一步了解,同时提出一些运营方面的管控措施,以减少故障发生的几率和影响范围。

The main content of this paper is to introduce the causes of hydrogen-containing compression in metal expander of 110 kV inverted oil-less current transformer based on working experience, and to synthesize the chromatographic analysis before and after the transformer failure, the structural characteristics, the results of disassembly inspection, the oil-immersed current transformer and the causes of hydrogen exceeding the standard. It is hoped that the analysis can help readers to have a better understanding of the knowledge in this area, and put forward some operational control measures to reduce the probability of failure and the scope of impact.
