摘　　要：电力变压器是电力系统中的重要设备之一,而绕组则是其关键的组成部分,绕组的布置方式会对变压器的阻抗分配和绝缘布局产生影响。本文作者以220k V三相三绕组电力变压器为例,探讨了绕组布置对变压器阻抗和绝缘特性的影响,并总结了这种影响对于变压器成本的作用。The power system relies heavily on the power transformer,with its winding being a crucial component.The ar-rangement of these windings has a significant impact on both the impedance distribution and insulation layout of the transformer.This study focuses on a 220kV three-phase three-winding power transformer to explore how different winding arrangements influence the impedance and insulation characteristics,ultimately affecting the over-all cost of the transformer.
