未运行变压器油乙炔超标原因分析及对策研究

Cause Analysis and Corresponding Countermeasures of Acetylene Overproof Phenomenon in Unused Transformer Oil

文章针对市场反映和投诉未运行变压器油乙炔气体超标现象进行了系统调查和研究。结果表明:未运行变压器油乙炔超标主要是由于周围环境中含乙炔、在转油或真空脱气过程中选泵不当、电气设备中构件吸附乙炔以及变压器油溶解气分析不规范等造成的。

Systematic investigation of acetylene overproof phenomenon in unused transformer oil fed back from customers was carried out. The results showed that there being acetylene in surroundings, using non-conforming pump during oil transferring or vacuum degassing process, release of acetylene adsorbed on the transformer components surface and de-normalized operation during dissolved gas test are the main four factors leading to acetylene overproof in unused transformer oil.
