油浸变压器绝缘降低的原因分析及其现场处理方法

Analysis on Reasons of Insulation Reduction of Oil-immersed Transformer and Field Treatment

对油浸变压器绝缘降低的原因进行了分析,重点分析了纸纤维素绝缘受潮和变压器油介质损耗增加的原因,介绍了绝缘降低后的现场处理方法。

The reasones for tightness reduction of oil-immersed transformer were analyzed,especially the insulation moisture of paper cellulose and reasons for dielectric loss factor increase of transformer oil,then it introduced the field treatment after tightness reduction.
