Analysis and Treatment of a Light Gas Tripping of OLTC of Converter Transformer

本文中作者介绍了一起换流变有载分接开关轻瓦斯跳闸故障的检查与分析处理过程。对有载分接开关各部位进行排气检查,并对分接开关油样与气体继电器气样进行试验,最终判断出故障原因,提出了相应建议。

The inspection and analysis process of a light gas trip fault of the OLTC of a converter transformer is introduced by the author in this paper.Perform exhaust inspec-tions on all parts of the on-load tap-changer,and test the oil samples of the tap-changer and the gas samples of the gas relay.The cause of the failure is judged and corresponding suggestions are presented.
