为更经济可靠地设计 2 2 0kV自耦有载调压变压器 ,对比分析了带角接稳定绕组的自耦有载调压变压器的波过程。定量计算分析各种可能的雷电冲击方式下各线圈尤其是调压线圈的电位振荡后得出 ,合理的线圈结构形式即高压线圈末端正反调压、调压线圈多路并联纠结 ;自耦有载调压变压器的线圈之间和线圈本身的电位振荡比普通变压器要严重得多 。
In order to design 220 kV on-load tap-changing auto-transformer reliably and economically, the wave course of on-load tap-changing auto-transformer with horn connections stabilizing winding is analyzed in this paper. Each winding, particularly the tap-changing winding, is calculated for its electric potential vibrations, which may happen under various possible lightning surge. And thus a reasonable winding structure is obtained. It is also found the electric potential vibration between the winding and the winding itself in on-load tap-changing auto-transformer is much bigger than that of the ordinary transformer. Two methods are proposed to restrict the max. electric potential on tap-changing winding.
