摘　　要：在有载调压变压器中,有载分接开关是重要的组成部件,运行中切换频繁,发生渗漏油、拒动及故障几率较高。通过2起变压器有载开关故障实例,深入分析了事故的原因,避免类似问题的发生,提高变压器运行可靠性.。On- load tap changer is an important component part in OLTC transformers,there are a lot of problems in actual operation such as frequent switching operation,oil leakage,a higher probability of failure,tripping and other abnormalities. Through two transformer＇ s fault cases,the detailed analysis of the fault cause is provided. This paper points out the importance of strict quality control and the need for strictly following the operation rules of on- load tap changer,avoiding similar problems to improve the operation reliability of power grid.
