摘　　要：变电站最重要的设备是变压器,正常情况下变压器的油位随变压器负荷和环境温度的变化而变化。但油位却有可能随着这些条件的变化出现一些异常情况,如冬季发生油位过低,轻瓦斯保护动作现象,妥善排除这些异常情况,有利于变压器的安全可靠运行。Transformer is the most important equipment in substation.Under normal conditions,the oil level of the transformer changes with the transformer load and ambient temperature.However,the oil level may be abnormal with the change of these conditions.If the oil level is too low in winter,the light gas protection will act.Properly eliminating these abnormal conditions is conducive to the safe and reliable operation of the transformer.

关 键 词：气温 变压器油位过低 轻瓦斯动作
