摘要
介绍了220kV变压器绕组通过匝绝缘与油道的配合来降低绕组的匝绝缘尺寸,分析了梯度电压与匝绝缘和油道尺寸的关系曲线,计算了线饼间的复合电场分布情况。
The method of reducing the winding turn insulation sizes of 220kV transformer by cooperating with turn insulation and oil duct is introduced. The relation curve of gra- dient voltage, turn insulation and oil duct sizes is analysed. The electric field distribution of disc is calculated.
