| 摘 要： | 维护变压器绝缘电阻在正常值范围运行至关重要。对110 kV变压器绝缘降低现象进行分析,认为是变压器在安装过程中遭遇下雨进水受潮所致。经对变压器干燥处理后绝缘电阻合格。指出绝缘电阻测量和数据分析中存在的问题。

| Abstract: | it is extremely important to keep the transformer insulation resistance in its normal value range.An insulation resistance degradation of 110 kV transformer is analyzed and it is considered that it was the damp of the rain during the transformer installation that led to the degradation.The insulation resistance is qualified after dehydrating disposal.Problems in the process of insulation resistance measurement and data analysis are pointed out. |
