大型变压器现场真空热油喷淋干燥之经验

Discussion on Vacuum Oil Atomization Dryness in field for Large Transformer

分析大型变压器现场真空热油喷淋雾化干燥过程,发现变压器干燥时凝结水的析出呈现周期性变化,同时、破真空、间断干燥可以提高变压器析出凝结水的速度,缩短变压器干燥时间。

The vacuum oil atomization dryness in field for large transformer is analyzed. It is found that the separating out of condensation water is periodic during the dryness of transformer. The discontinuous dryness can increase the separating out speed of condensation water and decrease the drying time.
