摘　　要：本文作者通过多个实例,简析在变压器制造厂的不当气相工艺,纸板内层形成“空腔”,且浸渍工艺不良导致纸板内层放电的机理。提出先加热油再排油和抽真空的加强工艺措施,对改善纸绝缘的二次浸渍有较好的工艺效果。Based on many examples,analysis the discharge mechanism Inner layer of the transformerboard due to the"Voids"by poor process technology for vapor-phase drying and the oil impregnation at the voids.Propose enhanced process measures of heating oil first and then draining oil and vacuuming,which are effective in improving the secondary impregnation of the transformerboard.
