摘　　要：500kV单相自耦中压无载调压的变压器,当调压绕组与低压绕组相邻、中压截波入波时,会在低压到铁心之间感应出很高的冲击传递电压,本文使用波过程仿真的方法,对比了不同的调压连接方式下低压到铁心之间传递电压的变化,进而得出调压的最优连接方案。Regulating winding is adjacent to low voltage winding is a typical winding arrangement for 500 kV single-phase autotransformer with off-circuit tap.During lightning impulse tests,a high impact transfer voltage is induced between the low voltage and the core.In this paper,the wave simulation is used to compare the transfer voltage in key area with different regulated connection modes.The optimal connection scheme is obtained.
