摘要:

目前国内绝大多数变压器油含气量超标皆为空气进入引起的,在变压器含气量超标处理过程中,除了要准确分析含气量超标原因外,采取科学的、恰当的检查处理步骤,对防止新的空气进入和空气残留,防止设备损坏,减少检查处理过程中的动作浪费具有重要意义。总结了梨园电站处理500kV变压器含气量超标问题过程中的经验,对变压器含气量超标检查处理步骤和工艺控制措施进行了详尽描述,对同类型变压器含气量超标处理有借鉴意义。

Abstract:

At present, the excessive gas content in the transformer oil are mainly caused by air entry. In the process of excessive gas content in the transformer, scientific and appropriate inspection steps are taken to analysis the reason for excessive gas content accurately, to prevent the new air entry and air residue, and to prevent the equipment damage. It is important to reduce unnecessary operation in the process of processing. It summarizes the useful experience in the process of dealing with the excess gas content of 500kV transformer in Liyuan Power Station, and gives a detailed description of the process and control measures for the inspecting and dealing with the gas content that exceeds the standard in the transformer, which can be used for reference to the treatment process for transformers of the same type.
